Food grade sodium tripolyphosphate is not as "horrible" as you think

 With the development of society nowadays, people are no longer confined to local cuisine. The cuisines of all parts of the country and even the world are no longer restricted by time and space, and can be eaten anytime, anywhere. It is precisely because of the development of the food processing industry that the use of food additives has achieved unprecedented development. Along with this, many foods have been added with many additives in order to prevent deterioration. Of course, there are also added for other purposes such as taste, deliciousness, etc. Should people reject these additives and look for more pure foods? Today Chuandong Chemical is here to talk about food additives, using sodium tripolyphosphate, which is widely used in phosphates, to talk about food additives.

The production of food additives is due to the fact that in daily life, the produced food has great defects in processing and storage due to the limitation of food properties. At this time, it is necessary to artificially add certain specific additives to the food to help better process the food. In the final analysis, it is to satisfy a better life. Now we can list a few of the more common additives.

Preservatives must be the first thing that many people think of. In recent years, news about preservatives has been endless. Are preservatives really that terrible? Preservatives are not only for the preservation of convenience foods, extending the shelf life of foods, but also to prevent or slow down the oxidation reaction of foods and prevent foods from spoiling due to microbial activities. At the same time, it prevents the formation of harmful oil and fat oxides in food, avoids food deterioration, and endangers the safety of consumers. Therefore, preservatives can not only ensure the quality of food, but also protect people's health.

Coloring agent is also a very commonly used food additive in recent years. It can not only improve the appearance of food, but also beautify the food, and better stimulate people's interest in food. Some food additives are rich in nutrients. For example, β-carotene can strengthen the immune system and prevent cardiovascular and cerebrovascular diseases and cataracts. Such additives are extracted from natural substances and will not endanger human health and safety. While coloring food, they also provide certain nutrients to the human body.

Water retention agent is a food additive commonly used in the processing of meat products and aquatic products. The addition of sodium tripolyphosphate can chelate Ca2+, Mg2+, Fe2+ ions, improve water retention performance, and improve antioxidant effect. After adding sodium tripolyphosphate, the calcium and magnesium ions originally bound to the muscle are chelated, and the carboxyl groups in the muscle protein are released. Due to the electrostatic force between the carboxyl groups, the protein structure relaxes, which can absorb more water and improve water retention.

In addition, sodium tripolyphosphate, sodium pyrophosphate and sodium hexametaphosphate can improve protein water retention during the interaction with protein. Since a single phosphate can not achieve the desired effect, the use of a compound phosphate as a water retaining agent for meat products can not only expand the scope of action of a single phosphate, but also reduce the dose of a single phosphate, reduce dosage and reduce costs, and improve food performance. Flavor and taste. As long as the national regulations and requirements on the use of food additives are strictly enforced, food additives can be added with confidence.
