What is DL-Malic acid?
As a common food additive and flavoring agent, DL-malic acid is widely used in jelly and fruit-based food, which helps food absorption and improves appetite. As a sour agent, it can be used instead of citric acid; it is often used as a sour agent for refreshing beverages, cold foods, processed foods, a preservative, and a color-retaining agent for fruit drinks.
In the non-food industry, it can be used in pharmaceuticals, cosmetics, metal cleaners, industrial deodorants and buffers, etc. In the textile industry, it is used as an anticoagulant, a raw material for fluorescent whitening agents, etc. As the role of DL-malic acid in the food and pharmaceutical industries is gradually recognized by people, its market demand is also increasing. Among them, in the application of medicine, foreign advanced standards have put forward high requirements for its purity, so its synthesis and refining process have certain difficulties in industrial production.
DL-Malic acid Uses
DL-malic acid is used in the food industry as a sour agent, color retainer, preservative and an emulsion stabilizer for egg yolks, and is also used in pharmaceuticals. Widely used in jelly and other fruit-added foods, it helps food absorption and improves appetite. As an acidulant, it can be used instead of citric acid, and is often used as an acidulant, a preservative for soft drinks, cold foods, processed foods, and a color-retaining agent for fruit drinks.
DL-malic acid is an internationally recognized safe food additive. It is used as a sour agent, a preservative and a pH regulator. Its sour taste is soft and long-lasting, and its sour taste is 20% stronger than that of citric acid. It can be used in all kinds of food and can be used in moderation according to production needs.
- In the non-food industry, DL-malic acid can be used in pharmaceuticals, cosmetics, metal cleaners, industrial deodorants and buffers, etc. In the textile industry, it is used as an anticoagulant, a raw material for fluorescent whitening agents, etc.
- DL-malic acid can be used as one of the synthetic raw materials of descaling agent and fluorescent whitening agent in the chemical industry. It can be added to shellac varnish or other varnishes to prevent the paint surface from crusting. Polyester resin produced with this acid And alkyd resins are special-purpose plastics.
Application preparation of DL-malic acid
DL-sodium hydrogen malate is a good food additive, which is widely used in aquatic products and meat food because it can increase the freshness of food and give it a good taste. Because it has a certain saltiness, it can be used as a substitute for table salt for food processing and manufacturing, and the amount of table salt can be reduced. In addition, since the content of sodium in DL-sodium hydrogen malate is lower than that of table salt, replacing table salt with DL-sodium hydrogen malate is more suitable for patients with high blood pressure, kidney disease and heart disease.
CN201510001761.3 provides a preparation method of DL-sodium hydrogen malate with simple method and high yield. The technical problem to be solved by this invention adopts the following technical scheme to realize: a kind of preparation method of DL-sodium hydrogen malate is, in the presence of a small amount of anhydrous sodium carbonate, trihydrate DL-disodium malate crystal and DL- The malic acid solids are mixed and ground under solvent-free conditions to form the reaction. The invention utilizes a solvent-free solid grinding reaction method to prepare DL-sodium hydrogen malate, has the characteristics of easy operation, high raw material utilization rate and high product yield, and has no pollution to the environment, conforming to the concept of green chemistry.
