Problems solved by technology

[0008] Hygroscopicity is stronger than that of polylysine. It is not affected by acid and alkali and is stable to heat (120°C, 20min). It can inhibit heat-resistant bacteria and has inhibitory effects on Gram-negative and positive bacteria. The ion may be inactivated by binding to it [Shima S, Matsuoka H, ​​Iwamoto T, et al.Antimicrobial action of ε-poly-L-lysine[J].Antibiot 1984,37:1449-1455.]

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] A compound biological preservative, which is compounded with 300-800mg / L monosodium fumarate and 200-500mg / L polylysine at a volume ratio of 1:9-11:1 and then added 0.02- 0.04% tea polyphenols.

[0028] The preferred ratio is: it is obtained by compounding 600mg / L monosodium fumarate and 400mg / L polylysine at a ratio of 7:1 and then adding 0.03% tea polyphenols.

Abstract

The invention relates to a compound biological preservative, which is characterized by compounding 300-800mg / L of monosodium fumarate with 200-500mg / L of poly lysine in accordance with the ratio of 1:9-11:1 and then adding 0.02-0.04% of tea polyphenol. The compound biological preservative has the characteristics of high efficiency, safety and no toxic and side effect, is good in broad-spectrum antibacterial property, is low in minimum inhibitory concentration, can not only inhibit the growth of bacterial colony in food, but also can maintain the moisture content, sensory quality and a variety of flavor components, and the compound biological preservative is suitable for the preservation of food, is especially suitable for casual fish sheet preservation, and has the very good application prospect.

Description

technical field [0001] The invention relates to a preservative, especially a compound biological preservative. Background technique [0002] Although there are various styles and types of food, the three aspects of safety, nutrition and sensory properties as food characteristics have not changed, and safety has attracted people's attention as the first of the three [Wu Xiangsheng. New ideas of industrial development [J]. Cold drink and quick-frozen food industry, 2004,10(4):37-42.]. [0003] In recent years, leisure fish fillets have been favored by consumers as a ready-to-eat leisure food with complete color, aroma and taste. While it is popular, the quality assurance of leisure fish fillets is still very concerned. Antiseptic preservation is an important measure to maintain food quality and safety. The most used preservatives today are chemical preservatives such as sorbic acid (potassium) and benzoic acid (sodium). Although their antibacterial effect is very good, the ch...
