With the continuous development of science and technology, the food processing industry is also constantly innovating and progressing. HPP technology is a new type of food processing technology that can effectively kill microorganisms in food and extend the shelf life of food while maintaining the original nutrients and taste of food. It has broad application prospects. This article will introduce in detail the principles, application fields and prospects of HPP technology.
1. Principle of HPP technology
HPP technology, or ultra-high pressure processing technology, is a new technology that uses high pressure to process food. Under normal temperature and pressure, microorganisms in food are in a dormant state and will not reproduce. However, under high temperature and high pressure, the microbial proteins will be denatured, the cell membranes will be destroyed, and they will lose their activity. Food treated with HPP technology can extend the shelf life while maintaining the original nutrients and taste of the food.
The working principle of HPP technology is mainly to apply pressure to the food through physical means, causing the moisture and other liquids in the food to be compressed and the distance between molecules to be reduced, thereby increasing the permeability of the microbial cell membrane and denaturing the microbial proteins. Cell membrane rupture. At the same time, ultra-high pressure treatment can also inactivate enzymes in food to achieve the purpose of sterilization.
2. Application fields of HPP technology
The application fields of HPP technology are very wide and can be involved in many food processing fields. The following are some of the main areas where HPP technology is used:
1. Fruit and vegetable processing
Fruits and vegetables are an important part of people's daily lives, but are often difficult to store and transport due to their short shelf life. HPP technology can effectively kill microorganisms in fruits and vegetables, extending their shelf life while maintaining their original nutrients and taste. Therefore, HPP technology has broad application prospects in fruit and vegetable processing.
2. Meat processing
Meat is an important source of protein for people, but its shelf life is short and it easily deteriorates. HPP technology can kill microorganisms in meat and extend the shelf life of meat while maintaining the original nutrients and taste of meat. Therefore, HPP technology also has broad application prospects in meat processing.
3. Dairy processing
Dairy products are an important part of people's daily lives, but are often difficult to store and transport due to their short shelf life. HPP technology can effectively kill microorganisms in dairy products and extend their shelf life while maintaining their original nutrients and taste. Therefore, HPP technology has broad application prospects in dairy processing.
4. Cereal product processing
Cereal products are an important source of carbohydrates for humans, but they have a short shelf life and are prone to spoilage. HPP technology can kill microorganisms in cereal products and extend their shelf life while maintaining their original nutrients and taste. Therefore, HPP technology also has broad application prospects in cereal product processing.
5. Beverage product processing
Beverage products are an important part of human daily life, but beverage products have a short shelf life and are prone to deterioration. HPP technology can kill microorganisms in beverage products and extend their shelf life while maintaining their original nutrients and taste. Therefore, HPP technology has broad application prospects in beverage product processing.
3. Application prospects of HPP technology
As people's living standards improve and their attention to food safety and nutrition increases, the food processing industry is also constantly innovating and progressing. As a new type of food processing technology, HPP technology has many advantages: it can not only effectively kill microorganisms in food and extend the shelf life of food, but also maintain the original nutrients and taste of food; it can also reduce the number of drugs in food. The presence of harmful substances such as residues improves food safety. Therefore, HPP technology has broad application prospects in the future.
First of all, as people's awareness of healthy diet continues to increase, the demand for natural, healthy, and additive-free foods continues to increase. HPP technology can effectively kill microorganisms, extend the shelf life, and maintain the original nutrition and taste without adding preservatives and other substances, which is very consistent with this market demand. Secondly, with the continuous development of e-commerce, people's living habits are changing very rapidly. This new type of high-voltage technology plays an important role in effective protection. Furthermore, as a country with a large population, China still has a large number of low- and middle-income groups. The stratification of national consumption into high, middle and low grades will inevitably present both challenges and opportunities, so the application prospects are very broad.
