Food Grade Soda Ash . Its main use is quite extensive. In the field of food production, there are many applications. First, it can be used in flour products. When making fermented flour products such as steamed buns and flower rolls, an appropriate amount of Food Grade Soda Ash is added to adjust the pH of the dough. Because yeast produces acidic substances during fermentation, soda ash reacts with it to neutralize the acidity and balance the acid and alkali of the dough, thereby improving the taste of the dough, making it softer and adding unique flavor. Second, it is also indispensable in the cleaning process of food processing. Because it has a certain decontamination ability, it can be used to clean food processing equipment, containers, etc. It can effectively remove oil stains and impurities, ensure the cleanliness of the food processing environment, and ensure food safety and hygiene. Third, it is also used in the production of some beverages. For example, in the production of some traditional carbonated beverages, it can adjust the pH and taste of the beverage, help form a suitable flavor, and give unique quality to the beverage. Fourth, when processing some meat products, adding an appropriate amount can improve the water retention of the meat. Reduce water loss in meat products during cooking, make the meat more tender and juicy, and improve the quality and taste of meat products. It can be seen that Food Soda Grade Ash plays a significant role in the food field and makes a significant contribution to ensuring food quality and safety.

Food Grade Soda Ash, which is quite different from industrial grade soda ash. First word purity, food grade soda ash has extremely high purity and contains very few impurities. It goes through multiple refining processes to ensure compliance with food safety standards. Because it is used in food processing, if the impurities exceed the standard, or cause damage to the quality of food, it endangers the health of consumers. In contrast, industrial grade soda ash, although it also has a certain purity, does not require more stringent impurities than food grade, and some industrial uses can accommodate appropriate amounts of impurities. Second discussion on the content of heavy metals and harmful substances. Food grade soda ash strictly restricts heavy metals such as lead, mercury, arsenic, etc., and the content is almost zero. Because food processing is related to people's dietary safety, trace heavy metals may also be enriched in the human body, endangering health. Industrial-grade soda ash has much looser requirements for the content of these heavy metals, because its application scenarios are mostly industrial production and do not directly contact the human body. Furthermore, the production environment and process are different. Food-grade soda ash is produced in a strictly hygienic environment, and the production equipment is regularly cleaned and disinfected to prevent microbial contamination. Its production process follows food safety regulations. Industrial-grade soda ash production environment mainly meets industrial production conditions, focusing on production efficiency and cost control, and the hygiene conditions are not as detailed as food-grade requirements. Packaging and labeling are also different. Food-grade soda ash packaging needs to meet the food packaging material standards to ensure that the product is not contaminated during storage and transportation, and the packaging is clearly marked with the words "food grade" and the applicable food range and other information. Industrial-grade soda ash packaging focuses on protecting the product from moisture and damage, and the logo mainly covers the common information of industrial products such as product name, specification, manufacturer, etc.

Food Grade Soda Ash, its Quality Standard is quite critical. In ancient times, although there was no such precise and detailed standard as today, there were corresponding considerations. In terms of purity, food grade soda ash needs to be quite high in purity, and the impurity content is extremely low. If there are many impurities, it will enter the food or be harmful to the human body. In ancient times, refined soda ash also sought to remove visible foreign bodies such as sand, gravel, soil, etc. Although the method is different from today, it is also a pure heart. In terms of pH, food grade soda ash should have an appropriate pH. Too acid or too alkali, both affect the quality of food. Ancient craftsmen used experience and simple methods to measure its pH to meet the needs of food production. Furthermore, the content of heavy metals must be strictly controlled. Heavy metals such as lead and mercury, even in small amounts, are harmful to health if ingested for a long time. Although the detection methods were limited in ancient times, the selection of materials and the production process also tried to avoid the introduction of such harmful substances. Microbial indicators cannot be ignored. If there are too many microorganisms in food-grade soda ash, it may cause food deterioration. Ancient production, although there is no advanced technology of modern sterilization and disinfection, still pays attention to the cleanliness of the production environment and prevents the growth of microorganisms. In addition, appearance indicators such as whiteness are also required. White and pure soda ash is more popular for food production. The ancient alkali production also improved its whiteness through multiple refining and other methods. Although the ancient and modern methods are different, the purpose of ensuring the quality of food-grade soda ash and making it suitable for food has never changed.

Food Grade Soda Ash. In food processing, its correct usage is very critical. Food grade soda ash can be added in moderation in the production of pasta. If steaming steamed buns, dissolve an appropriate amount of soda ash in water and add it to the dough. Because the dough ferments to produce acid, soda ash responds to it, which can remove the sour taste and make the steamed buns puffy and taste better. However, the dosage must be accurate. If there is too much, the steamed buns will taste bitter and yellow; if there is too little, the sour taste will be difficult to remove. It is also useful in meat processing. It can improve the water retention of meat and make the meat more tender and juicy. For example, when processing beef, soaking in a certain proportion of pure alkali solution can improve the taste of the meat. But the amount also needs to be strictly controlled to prevent affecting the flavor and quality of the meat. In the production of some beverages, food-grade soda ash can adjust the pH. For example, for specific fruit juice beverages, adding an appropriate amount can balance the taste and make the beverage more palatable. However, the dosage needs to be accurately determined according to the beverage formula and expected taste. In short, food-grade soda ash used in food processing needs to clarify its characteristics, and use it carefully and accurately according to different food categories and processing technologies in order to exert its effectiveness and ensure food safety and quality.

Food - Grade Soda Ash, its storage conditions are quite critical. It needs to be placed in a cool place, because extreme heat will cause its chemical properties to change. Ancient books say: "In a dry place, things are prone to change their properties." If the temperature is high, or some ingredients in soda ash accelerate the reaction, it will affect the quality. And keep a dry environment and avoid a humid place. "The Book of Rites · Lunar" says: "The soil is moist and hot, and all things are beautiful." Humid like the heat, it is easy to make soda ash deliquescent. Once deliquescent, not only the shape changes, but also its purity and food safety are affected. Furthermore, the storage place should be well ventilated. As the old saying goes "running water does not rot, and the household does not coddle", the air circulation can avoid the accumulation of harmful gases and prevent it from reacting with soda ash. When storing, it needs to be separated from other chemicals. "Huainan Zi Main Practice" says: "Those who are similar to the husband's things are confused by the master." Different chemicals coexist, or cause chemical reactions, endangering food safety. At the same time, the storage container should be made of corrosion-resistant materials, such as glass, specific plastics, etc., to ensure the stability of soda ash properties and not be disturbed by the container material, so as to achieve the purpose of safe storage.

Food Grade Soda Ash, has a wide range of main application fields. In the food processing industry, its use is particularly important. When making noodles, adding food grade soda ash can improve the ductility and toughness of the dough, making the noodles stronger and less breakable when cooked. In the field of bread baking, it can adjust the pH of the dough, help the yeast to ferment, make the bread swell more ideally, have a softer texture, and improve the taste and quality. When making biscuits, it can make the biscuits more crispy and optimize the sensory properties of the product. In the beverage industry, food grade soda ash also plays a key role. In the production of some carbonated beverages, an appropriate amount is added to adjust the pH of the beverage, balance the taste, enhance the dissolution stability of carbon dioxide, and make the bubbles last longer, thereby improving the quality and taste experience of the beverage. The processing of canned food is also inseparable from food-grade soda ash. It helps to process raw materials of fruits and vegetables. If it can soften the skin of fruits and vegetables, it is convenient for subsequent processing processes such as peeling, and it can maintain the color and texture of fruits and vegetables, and improve the appearance and quality of canned food. In the brewing industry, food-grade soda ash can be used to adjust the pH of the fermentation broth, create a suitable environment for microbial fermentation, and promote the smooth progress of the fermentation process, which in turn affects the flavor and quality of the final brewed product. In addition, in the production of food additives, food-grade soda ash is used as a basic raw material to participate in the synthesis process of various additives, providing a rich variety of functional additives for the food industry to meet different food processing needs. In short, food-grade soda ash is of great significance in ensuring food quality and optimizing processing processes in many food-related fields due to its unique chemical properties and functions.

Food Grade Soda Ash can have potential impacts on the environment if used improperly in food processing. As a pH regulator, leavening agent, etc., if the production wastewater is directly discharged, the high concentration of carbonate ions will increase the alkalinity of the water body, change the acid-base balance of the aquatic ecosystem, inhibit the activity of microorganisms, and affect the survival and reproduction of fish and shrimp; when used for cleaning food fermentation workshops, if the alkaline wastewater is not neutralized, it will corrode the drainage network and accelerate the rusting of metal pipes. However, under reasonable application, food grade soda ash has a high purity (impurities ≤ 0.5%), low residual risk, and can be degraded through biochemical treatment (such as anaerobic + aerobic process), and the impact on the environment is much less than that of industrial grade alkali agents. The key is that food companies need to optimize the water use process, recycle cleaning water, equip with acid-base neutralization tanks, control the pH of wastewater discharge at 6-9, and use closed feeding equipment to reduce dust emission, ensure workshop air quality (dust concentration ≤10mg/m³), and achieve a balance between food processing and environmental friendliness.

In food processing, Food Grade Soda Ash plays multiple roles based on its alkaline dissociation and chemical reaction characteristics: in pasta fermentation, as an auxiliary ingredient of leavening agent, carbonate ions react with acids (such as lactic acid and acetic acid) to generate CO₂ (Na₂CO₃ + 2CH₃COOH = 2CH₃COONa + CO₂↑ + H₂O), making the dough pores uniform and improving the fluffiness; in fruit and vegetable processing (such as olive pickling), alkalinity is used to destroy the pectin structure of cell walls, accelerate the removal of astringency and softening, and at the same time adjust the pH to inhibit microorganisms (when pH＞8, the mold reproduction rate is reduced by 70%); in beverage production, it acts as a buffer to stabilize the pH (pH 6.5 - 7.5 for carbonated beverages), avoid excessive acid corrosion of packaging, and ensure the shelf life of the product. Because the impurities of food grade soda ash (such as heavy metals and chloride ions) are strictly controlled (Pb≤1ppm, NaCl≤0.3%), no harmful substances will be introduced after the reaction, which complies with the GB 1886.2 - 2015 standard, ensuring food safety and quality stability.

When used in food, food-grade soda ash has a great effect. In the field of food processing, it has a wide range of effects. The first to bear the brunt can be used as an acidity regulator. The taste of food is related to acidity, or over-acidity, or discomfort. Food-grade soda ash enters it, which can adjust acidity and make the taste perfect. If used in the making of bread, it can neutralize the acid generated by fermentation, making the bread taste pure and fragrant, and the taste is soft and pleasant. Furthermore, it has the ability to puff. In the making of cakes, food-grade soda ash is added, which decomposes when heated, escapes carbon dioxide, causing the inside of the cake to become porous, forming a delicious and beautiful state, which is favored by everyone. And food-grade soda ash can be used as a pasta improver. In the genus of noodles and steamed buns, it can be used to increase the toughness and ductility of the dough, making the quality of the pasta better. Noodles are not easy to break, and steamed buns are fluffy and chewy. It is also effective in the cleaning process of food processing. Because of its alkalinity, it can remove oil stains, keep processing utensils clean, and make the food processing environment in line with hygienic regulations, ensuring food safety. All of these, food-grade soda ash is indispensable in food processing, such as craftsmen's tools, and contributes greatly to the success of food.

Food Grade Soda Ash, its storage and transportation requirements are very critical. For storage, choose a dry, cool and well-ventilated place. Because food grade soda ash is hygroscopic, if it is in a humid environment, it is easy to be damp and agglomerate, which will damage its quality. The temperature of the warehouse should be controlled within a certain range, not too high, to prevent the quality from changing due to chemical reactions caused by temperature. And it should be separated from acids, ammonium salts and other substances with reaction risk to avoid danger from mixing. The storage place must be clean to prevent impurities from mixing and affecting its safety in the food field. As for transportation, it is necessary to ensure that the means of transportation are clean and dry, and there are no residues that may contaminate food-grade soda ash. Rainproof and moisture-proof measures should be taken during transportation, and the tarpaulin can be tightly covered. The loading and unloading process should be handled with care to avoid product leakage due to damaged packaging. The packaging materials used must also meet food-related safety standards and have good sealing to ensure that the product is not affected by external factors during transportation, and maintain its quality and purity, so as to ensure that food-grade soda ash can meet the strict requirements of food production and use during storage and transportation.

Food-grade soda ash is an important substance related to people's livelihood and diet, and its purity standard is not light. Food-grade soda ash, that is,is widely used in various fields of food processing, such as the loosening of flour products, the acid-base adjustment of beverages, etc. Its purity standard is extremely strict according to the current regulations. Generally speaking, the purity of food-grade soda ash needs to reach more than 99%. This high standard is related to food safety. If the purity is not sufficient, impurities are mixed into the food, or it may cause odor and damage the taste of the food; what's more, harmful impurities or endanger human health. And this purity standard has undergone various considerations and practical verification. In the process of production and preparation, exquisite processes must be used to remove impurities and improve its purity. From the ore, through calcination, dissolution, impurity removal, crystallization and other processes, step by step carefully, to obtain this high-purity food-grade soda ash. Only by strictly observing this purity standard can we ensure the safety and stability of food processing, so that what the people eat meets the requirements of health. It is based on the purity standard of food-grade soda ash, which is the cornerstone of the food industry and cannot be slack.

Food Grade Soda Ash In food sterilization, the antibacterial properties of the alkaline environment are used to assist disinfection: in canning processing, 2% - 3% pure alkali solution is prepared as a pre-cooking liquid, and the liquid alkalinity (pH 10 - 11) is increased at high temperature (80 - 90℃) to destroy bacterial cell membranes (such as Escherichia coli, 3-minute inactivation rate > 99%), while softening fruit and vegetable fibers to improve canning quality; in the production of fermented foods (such as fermented black beans), the raw materials are soaked in pure alkali solution (0.5% - 1%) to inhibit miscellaneous bacteria (such as mold spores, germination rate reduced by 60%), creating a favorable environment for beneficial bacteria (such as Bacillus subtilis); in food equipment cleaning, alkaline solutions can decompose grease and protein dirt, and rinse with hot water (60 - 70℃) to remove biofilms on the equipment surface (such as yeast residues) and reduce microbial growth. Because the residue of food grade soda ash is easy to clean (high water solubility, 19.5g/100mL at 20℃), and meets safety standards, it will not cause secondary contamination to food, and becomes a "green additive" in the food sterilization process, assisting in ensuring food microbiological indicators (total colony count ≤1000CFU/g, pathogenic bacteria must not be detected).

Determine the amount of Food Grade Soda Ash to be added to accurately match food technology and safety standards: in pasta processing, add 0.5% - 1.5% of the mass of flour, combined with yeast activity (at a temperature of 25 - 30°C, reduce the amount by 10%) and dough moisture content (when >45%, increase the amount by 5%) to ensure uniform CO₂ gas production and avoid excessive alkaline taste; when pickling fruits and vegetables, according to the acidity of the raw materials (green plums with a pH of 3 - 4, the concentration of pure alkali solution is 1.5% - 2%) and the target of removing astringency (soaking for 24 - 48 hours), determine the optimal concentration through small tests to prevent excessive softening and resulting in a rotten taste; in beverage production, follow GB 2760 - 2014, the maximum usage in carbonated beverages is ≤0.5g/kg, combined with the amount of citric acid and phosphoric acid added, through conductivity monitoring (target value 500 - 800μS/cm) Dynamic regulation to ensure pH stability. At the same time, the purity of food grade soda ash (≥99.2%) must be considered, and the influence of impurities must be deducted when converting the theoretical dosage to ensure that the sodium content and heavy metal residues of the final product meet the national standards (sodium ≤200mg/100g, total arsenic ≤0.5mg/kg) to ensure consumer safety.

Compared with industrial grade soda ash, Food Grade Soda Ash has special requirements focused on safety and purity: raw materials must be food grade salt and ammonia (heavy metal ≤ 1ppm), the production process must be strictly controlled (GMP workshop, air cleanliness ≥ 100,000 grade), to avoid cross contamination; impurity limits are strict, heavy metals (Pb ≤ 1ppm, Cd ≤ 0.5ppm), arsenic (As ≤ 0.5ppm), chloride (NaCl ≤ 0.3%) are much lower than industrial grade (industrial grade heavy metal ≤ 10ppm, NaCl ≤ 1%); HACCP and ISO 22000 certification must be passed, each batch is accompanied by COA (Certificate of Analysis), and the entire production process is traceable (from raw materials to finished products, records ≥ 2 years). Food grade PE film (thickness ≥ 0.08mm) is used for packaging to avoid plasticizer migration, storage warehouses are separated by independent partitions (≥ 5m away from industrial chemicals), and temperature and humidity are controlled at 20 ± 5℃, RH ≤ 60% to prevent moisture absorption and agglomeration from affecting purity. These special requirements ensure that food grade soda ash does not introduce safety hazards when it comes into contact with food, supporting its compliant application in industries such as baking, beverages, and pickling, and forming essential differences with industrial grade soda ash in production environment, quality control, and risk prevention.

The production process of food-grade pure enzymes is also related to the key skills of food production. Today, in ancient Chinese, I will talk about one or two in detail. The production of food-grade pure enzymes is first in the selection of materials. It is necessary to choose high-quality biological raw materials. This raw material should be pure and unstained, with the characteristics of high enzyme activity. If a specific strain is used as the source, the strain needs to be carefully selected and cultivated in a favorable environment to ensure that its activity is fully displayed, laying the foundation for the output of enzymes. The second time is the cultivation method. The appropriate temperature, humidity and nutrition are essential. When the strain is placed in a special culture vessel, the temperature is precisely regulated according to the characteristics of the enzyme, or constant temperature, or temperature change, so that the strain can multiply orderly. Wet is also the key. If it is too wet, it is easy to stain strains, and if it is too dry, it will be unfavorable for growth. Nutrients are supplied on demand, and the ratio of sugar and nitrogen sources is exquisite, so that the strains can thrive and the output of enzymes can also be increased. Furthermore, the technique of extraction is crucial. When the strains are cultivated and mature, the amount of enzymes is enriched, which is a matter of extraction. First use physical methods, such as centrifugation, filtration, and initial separation of impurities. Following the chemical method, select the appropriate reagent, and separate it from impurities according to the chemical properties of the enzyme. This process requires fine operation. If there is a slight difference, the purity and activity of the enzyme will be affected. Then purification. There are various methods of purification, and chromatography is often used. According to the size and charge of the enzyme and the impurity molecule, when the chromatography column, the components are separated one after another to obtain a high-purity enzyme. And the purification process needs to be in a clean environment to avoid external pollution and maintain the purity of the enzyme. At the end, test and verify. Use sophisticated instruments to test the purity, activity and stability of the enzyme. If the purity is not up to standard, it needs to be purified again; if the activity is insufficient, it must be corrected for cultivation or extraction errors. Stability is related to the effectiveness of enzymes in different environments, and is also the focus of detection. All these are essential for the production process of food-grade pure enzymes. Each step is interconnected and indispensable, and must be handled with a rigorous heart and exquisite skills to achieve high-quality food-grade pure enzymes for use in the production of food.
