阅读说明：本技术 一种可高温杀菌皮冻的制备方法 (Preparation method of skin jelly capable of sterilizing at high temperature ) 是由 刘树兴 延梦瑶 吴立新 岳娟 于 2020-04-09 设计创作，主要内容包括：一种可高温杀菌皮冻的制备方法,将猪皮经挑选去毛清洗干净后加清水熬煮去除肉皮表面的油脂,切条；加入清水及食盐、料酒,熬煮去掉表面泡沫杂质；然后向其中加入可得然胶,继续熬煮,搅打斩拌后,真空填装入人造肠衣,卡扣密封,于121℃高温杀菌20分钟,冷却后保温检验合格后入库常温贮藏。本发明通过添加可得然胶,能够对制备的皮冻进行高温杀菌,可以常温贮藏,延长其保质期,并且能够防止经过高温杀菌的皮冻在常温贮藏时融化。(A preparation method of skin jelly capable of sterilizing at high temperature comprises selecting Corii Sus Domestica, removing hair, cleaning, adding clear water, decocting to remove oil on the surface of Corii Sus Domestica, and cutting into strips; adding clear water, salt and cooking wine, and decocting to remove surface foam impurities; adding curdlan, decocting, stirring, chopping, vacuum filling into artificial casing, sealing with buckle, sterilizing at 121 deg.C for 20 min, cooling, maintaining the temperature, inspecting, and storing at room temperature. The curdlan is added, so that the prepared skin jelly can be sterilized at high temperature, can be stored at normal temperature, prolongs the quality guarantee period, and can be prevented from melting during normal-temperature storage.)

1. A preparation method of a skin jelly capable of sterilizing at high temperature is characterized by comprising the following steps:

1) selecting pigskin, removing hair, cleaning, adding 2-3 times of clear water, decocting for 10-20 minutes, taking out, draining, removing oil on the surface of the pigskin, and cutting into strips;

2) adding clear water, salt and cooking wine according to the proportion of adding 4-8 parts of water into 1 part of pigskin, decocting for 10-20 minutes, and removing surface foam impurities;

3) adding curdlan with the mass of 0.5-30% of the pigskin, continuously boiling for 20-40 minutes, beating and chopping, filling an artificial casing in vacuum, sealing by a buckle, sterilizing at the high temperature of 121 ℃ for 20 minutes, cooling, preserving heat, inspecting, and storing at normal temperature.

Technical Field

The invention belongs to the field of food, and particularly relates to a preparation method of a skin jelly capable of sterilizing at high temperature.

Background

The skin jelly is a favorite food for people and is prepared by decocting pigskin and the like. The commercial skin jelly in the current market has short shelf life and can only be stored in a cold storage mode due to the fact that high-temperature sterilization is not carried out, even if food preservatives are added. If high-temperature sterilization is adopted, the characteristics of the skin jelly gel are weakened, and the skin jelly gel is easy to melt after being stored at normal temperature, so that the appearance quality and the taste of the product are influenced.

Disclosure of Invention

The invention aims to provide a preparation method of a skin jelly capable of being sterilized at high temperature.

In order to achieve the purpose, the invention adopts the technical scheme that:

1) selecting pigskin, removing hair, cleaning, adding 2-3 times of clear water, decocting for 10-20 minutes, taking out, draining, removing oil on the surface of the pigskin, and cutting into strips;

2) adding clear water, salt and cooking wine according to the proportion of adding 4-8 parts of water into 1 part of pigskin, decocting for 10-20 minutes, and removing surface foam impurities;

3) adding curdlan with the mass of 0.5-30% of the pigskin, continuously boiling for 20-40 minutes, beating and chopping, filling an artificial casing in vacuum, sealing by a buckle, sterilizing at the high temperature of 121 ℃ for 20 minutes, cooling, preserving heat, inspecting, and storing at normal temperature.

Curdlan is a food additive that is approved for use. The curdlan belongs to a thickening agent and can be used for foods such as meat products and the like, and is used in a proper amount according to production requirements, which is specified in the national standard food additive use standard of food safety of the people's republic of China GB 2760-2014.

The curdlan is added, so that the prepared skin jelly can be sterilized at high temperature, can be stored at normal temperature, prolongs the quality guarantee period, and can be prevented from melting during normal-temperature storage.
