E270 is the European food additive number assigned to lactic acid, a naturally occurring organic acid. It can be found in various fermented foods, such as yogurt, sauerkraut, and pickles. Lactic acid is produced by the fermentation of carbohydrates, primarily sugar, by lactic acid bacteria. This process not only contributes to the tangy flavor characteristic of many fermented products but also plays a role in food preservation.
However, the sale of monosodium glutamate is not without its challenges. Despite being recognized by food safety authorities, including the FDA and WHO, MSG has faced scrutiny and skepticism due to concerns about its health effects. Some consumers report adverse reactions to MSG, including headaches and allergic symptoms, which has led to a negative perception among certain demographics. As a result, food manufacturers are increasingly exploring natural alternatives to MSG, such as yeast extract and natural flavorings, to cater to health-conscious consumers.

Industrial Applications
The primary function of E220 in food preservation is its ability to inhibit microbial growth. By creating an environment that is hostile to spoilage-causing microorganisms, sulfur dioxide helps maintain the freshness and safety of food products. This is particularly important for dried fruits, such as apricots and raisins, which are prone to bacterial and yeast contamination.
Chemical Properties and Production
Not only do sorbates contribute to improved shelf stability, but they also have the added advantage of being effective at relatively low concentrations. This means that they can be used without compromising the sensory qualities of the food, fostering consumer acceptance.
5. Pricing Competitive pricing is always a factor in supplier selection. However, the lowest price does not always indicate the best value. Companies should weigh the total cost against the quality and service provided.
E242 is primarily used in alcoholic beverages, especially wine and beer, where it acts as a stabilizing agent. It is particularly advantageous for products that are sensitive to spoilage, such as ready-to-eat meals, sauces, and various processed foods. The additive is also utilized in non-food applications, such as cosmetics and pharmaceuticals, where preservation is equally crucial.
INS 635 is primarily used in various processed food items, such as soups, sauces, snacks, and ready-to-eat meals. Its ability to enhance umami, the fifth basic taste, makes it particularly popular in Asian cuisine, where depth of flavour is highly sought after. When used in moderation, INS 635 can improve the palatability of food products, making them more appealing to consumers and encouraging repeat purchases.
The use of sorbates as food preservatives has been evaluated and deemed safe by several health authorities, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). Both agencies have established acceptable daily intake levels for these compounds, which have been determined to pose minimal risk when consumed within those limits.
