Embodiment Construction

[0018] The following is a detailed description of the specific implementation of the antistaling agent proposed by the present invention in the grass chicken pot.

[0019] 1. After pulverizing the ebony plum, condense and reflux with 95% ethanol to extract, filter and concentrate with a rotary evaporator to obtain the original solution. After the stock solution was sterilized by filtration, it was stored at 4°C for future use.

[0020] The original solution here refers to: 1mL extract contains 1g of dried ebony extract.

[0021] 2. Prepare fresh-keeping liquid according to the following weight ratio:

[0022] Take 3-5g of lysozyme, 3-5g of nisin (purchased from Zhejiang Yinxiang) and 2.5-3ml of ebony extract. Mix and set aside.

[0023] 3. Test example:

[0024] 1. First, make mature grass chicken soup in a pot according to the conventional method, and cool it to room temperature.

[0025] 2. Obtain the volume of the soup in the soup pot.

[0026] 3. Referring to the vol...

Abstract

The invention discloses an antistaling agent for soup food and an application method thereof and relates to the field of technical research on agricultural products. The antistaling agent is formed by compounding extract of dark plum fruit, nisin and lysozyme according to a certain ratio. The antistaling agent consists of protein substances derived from biological sources and medicinal and edibleplant extract, does not comprise a chemosynthetic preservative ingredient and belongs to a natural and safe antistaling agent. Meanwhile, three ingredients are compounded, so that the antistaling agent has a wide antibacterial spectrum, gram-positive bacterium, gram-negative bacteria, yeast, mould and the like in soup can be effectively inhibited or killed, the shelf life of a product is prolonged, and the spoilage of the product is inhibited. Due to the adoption of the antistaling agent, the shelf life of the soup food under the refrigeration condition can be prolonged by about 4 days.

Description

technical field [0001] The invention relates to a fresh-keeping agent for soup and pot food, which belongs to the technical research field of agricultural products. Background technique [0002] Soup food has a long tradition in our country. Its soup is attractive, delicious and fragrant, and has the effect of nourishing the body. The bento-type soup pot products transformed by modern processing technology are favored by consumers because of the combination of "conventional, delicious and healthy". However, due to the rich nutrients and high water activity of soup and pot food, it is very easy to cause spoilage and deterioration due to the massive proliferation of microorganisms in the process of product storage, transportation and sales. It is difficult to realize long-distance transportation and preservation, and it is easy to cause huge damage. economic loss. Therefore, how to control microbial pollution and ensure the quality and safety of processed products has become...
