What are the characteristics of ultra-high pressure technology and membrane technology in fruit and vegetable processing and production technology

  With the rapid development of the fruit and vegetable processing industry, the processed fruit and vegetable products also have good quality, and the functional processed fruit and vegetable products are also developing rapidly. What are the fruit and vegetable processing and production technologies? Which is better, ultra-high pressure technology or membrane technology? Let's take a look together!
  Ultra-high pressure technology
  High-pressure technology can effectively overcome the defects caused by traditional thermal processing methods, and can effectively maintain the natural color, aroma, taste and nutrients of the processed food, injecting new vitality into the food processing industry. Compared with traditional heat treatment, ultra-high pressure technology can retain more nutrients, can effectively reduce the loss of heat-sensitive components, and can effectively maintain the original properties and flavors of food without producing the cooking smell brought by heat treatment .
  This technology has broad application prospects and great development potential. It can be applied in the food industry. Ultra-high pressure technology can save energy, operate safely, process simple, and be green and environmentally friendly. High static pressure technology can ensure the safety of sterilization, play an important role in fruit and vegetable processing, and can effectively avoid quality deterioration caused by high-temperature sterilization. It has been used in fermented products, pickled products, vegetable juices, canned fruits and vegetables, etc. is commonly used.
Membrane Technology
Membrane separation technology has been rapidly developed in the fruit and vegetable industry. Membrane separation technology can use natural or synthetic polymer membranes to separate, fractionate, purify and enrich two-component or multi-component solutes driven by external energy or potential difference. and solvents. The difference between membrane separation technology and traditional filtration is that membranes can separate at the molecular level, which is a physical process that does not require phase changes and additives. The product is non-polluting, has good selectivity, and can be processed on a large or small scale, or continuously or intermittently. Membrane modules can be used alone or in combination. The process is simple, easy to operate, easy to realize automatic operation, can be carried out at room temperature, the loss of volatile components is very small, and the original fragrance can be maintained; the separated raw materials have no pigment decomposition and browning reaction, and the membrane separation process is carried out in a closed system.
  The application of membrane technology in fruit and vegetable processing is mainly manifested in:
  The concentration of fruit and vegetable juice can not only reduce the volume of fruit and vegetable juice, but also improve the storage stability of fruit and vegetable juice, reduce the cost of packaging and transportation, and facilitate storage and transportation. Membrane separation technology is expected to develop in membrane materials, membrane devices and processes in the future, and its application in fruit and vegetable juice production will gradually expand.
Using membrane ultrafiltration instead of the above method to clarify fruit and vegetable juice has the characteristics of mild conditions, good clarification effect and less loss of nutrients, which can reduce labor, shorten production cycle, reduce cost and various reagents such as diatomaceous earth, pectinase, Consumption of filter aids. The above is the introduction of ultra-high pressure technology and membrane technology for fruit and vegetable processing and production technology. I look forward to being helpful to everyone.
