1. In Food Industry
Acidity Regulator: Used to regulate the acidity of food and improve taste.Food Flavoring Agent: Enhances the flavor of food and makes food more delicious.Fresh-keeping Agent: Plays a similar role as salt in the processing and preservation of meat products, ham sausage, aquatic products, etc. Moisture Retention Agent: Helps food retain moisture and extend shelf life.Widely used in beverages (such as vinegar drinks, fruit drinks, nectar, iced tea, sports drinks, calcium-fortified juices, etc.), meat products, oral liquids and other foods.
2.Use Effect and Safety
Sodium L-malate is an optical isomer of sodium malate, and has the same physical and chemical properties as sodium DL-malate except for optical activity. However, sodium L-malate has the ability to directly participate in the metabolism of organisms. Thus compared with sodium DL-malate, sodium L-malate is more beneficial to human health.
According to JECFA (United Nations Committee on Food Additives), the ADI (acceptable daily intake) of sodium L-malate is no specified, indicating it is safe under normal use. However, long-term excessive intake or inappropriate use may bring some side effects, such as indigestion, diarrhea, etc. Therefore, when using sodium L-malate, relevant safety standards and regulations should be followed, and excessive intake should be a- previous：Zinc L-malate
Next：Calcium Malate/Calcium 2-hydroxybutanedioate
