Embodiment 1

[0035] An alcohol preservative, containing the following components by weight percentage:

[0036] Adsorbent: silica gel 70%;

[0037] Antifungal agent: sodium diacetate 4%;

[0038] Fungicide: 15% edible alcohol;

[0039] Preservative: citric acid 5%;

[0040] Water: 6%.

[0041] The silica gel is 300-400 mesh silica gel.

Embodiment 2

[0043] An alcohol preservative, containing the following components by weight percentage:

[0044] Adsorbent: silica gel 60%;

[0045] Antifungal agent: sodium diacetate 3%;

[0046] Fungicide: 30% edible alcohol;

[0047] Preservative: citric acid 2%;

[0048] Water: 5%.

Embodiment 3

[0050] An alcohol preservative, characterized in that it contains the following components by weight percentage:

[0051] Adsorbent: 62% silica gel;

[0052] Antifungal agent: sodium diacetate 8%;

[0053] Fungicide: 17% edible alcohol;

[0054] Preservative: citric acid 3%;

[0055] Water: 10%.

[0056] The following are the weight loss rates of the three examples, which were tested using the following method: After preparing according to the formula, each gram of the sample is packed in a 20 mm*30 mm plastic wrap bag, and 100 holes are randomly punched with a needle. Weigh every 24 hours. The specific data are as follows:

[0057] Example 1:

[0058] Weight loss: 24 h weight loss of 0.18 g, 48 h weight loss of 0.30 g, 72 h weight loss of 0.39 g

[0059] Example 2:

[0060] Weight loss: 24 h weight loss of 0.15 g, 48 h weight loss of 0.26 g, 72 h weight loss of 0.35 g

[0061] Example 3:

[0062] Weight loss: 24 h weight loss of 0.13 g, 48 h weight loss of 0.22 g, 72 h weight loss of 0.30 g...

Abstract

The invention provides an alcohol preservative to solve the problem that existing alcohol preservatives can not be good in sterilization performance and keep pure tastes of food at the same time. The alcohol preservative comprises, by weight, 60-70% of silica gel which serves as an adsorbent agent, 3-8% of sodium diacetate which serves as a mildew prevention agent, 15-30% of edible alcohol which serves as a sterilizing agent, 2-5% of citric acid which serves as an antiseptic agent and 5-10% of water. The alcohol preservative has the advantages of being good in sterilization performance, capable of keeping the pure tastes of the food and preventing food poisoning, high in sterilization speed, non-toxic and harmless.

Description

technical field [0001] The invention belongs to food science and technology, in particular to a fresh-keeping agent for food. Background technique [0002] The alcohol gas generating agent delays the reproduction of the fungus, and does not reach the level of making it die. Therefore, we must always keep the initial bacterial count in mind, and we must strictly manage it during the food manufacturing stage to prevent high-concentration contamination of microorganisms. [0003] In addition, it should be noted that for red bean paste with high water activity, the storage time is short, and more additional preservatives are needed. Generally, the food with higher water activity is more likely to spoil, which is well known. When using alcohol generating agent, it is necessary to measure the water activity in various foods respectively, and determine the additional amount corresponding to the measured value. For the outer bag of the package, KOP / CP, OP / CP and other composite pa...
