I. Introduction
The food additive ε-Polylysine Hydrochloride is obtained from the controlled fermentation broth of Streptomyces diastatochromogenes through adsorption, desorption, and purification by ion exchange resin. It can be used as a preservative in fruits, vegetables, beans, edible fungi, rice and its products, wheat flour and its products, miscellaneous grain products, meat and meat products, seasonings, and beverages.
II. Properties
ε-Polylysine Hydrochloride is a light yellow powder with strong hygroscopicity and a slight bitter taste. It is a linear polymer of lysine. It is not affected by pH value and is thermally stable (120°C, 20 min). It can inhibit heat-resistant bacteria, so heat treatment can be carried out after its addition. However, when it encounters acidic polysaccharides, hydrochlorides, phosphates, copper ions, etc., its activity may be reduced due to combination. It has a synergistic effect when used in combination with hydrochloric acid, citric acid, malic acid, glycine, and fatty acid glycerides.
ε-Polylysine Hydrochloride with a molecular weight between 3600 and 4300 has relatively good antibacterial activity. When the molecular weight is below 1300, ε-Polylysine Hydrochloride loses its antibacterial activity.
III. Uses
The food additive ε-Polylysine Hydrochloride is obtained from the controlled fermentation broth of Streptomyces diastatochromogenes through adsorption, desorption, and purification by ion exchange resin. It can be used as a preservative in fruits, vegetables, beans, edible fungi, rice and its products, wheat flour and its products, miscellaneous grain products, meat and meat products, seasonings, and beverages. The "Announcement on Approving 4 New Varieties of Food Additives such as ε-Polylysine" approves ε-Polylysine as a new variety of food additive.
