Characteristics of non thermal sterilization technology

pubdate:2016-10-13 Author: Click:

Non heat treatment is the characteristic of the process without heating treatment. Heat treatment in food processing, in addition to kill microorganisms in food raw materials, but also can make the product due to the heating caused by the gelatinization of starch, protein denaturation caused by the change of the quality of the products, and then improve the digestion and appetite. For most food ingredients. After weighing the excellent results obtained due to heating and the quality degradation due to heating, the final decision of the conditions of its heating treatment. Especially for food related to vegetables and fruits, in order to avoid the loss of vitamins, color changes and the quality of the structure of the deterioration of the quality of the phenomenon. The processing method of high temperature and short time treatment should be considered by considering the factors such as the deterioration rate of product quality and the necessary heating conditions. Therefore, compared with the heating treatment, can maintain the product is easy to deteriorate the vitamins and pigments and other ingredients are the greatest feature of non thermal processing. From the point of view of energy consumption and heat treatment, the other characteristic of non heat treatment is that it can save energy. For the need to increase the temperature of raw materials to a certain extent through the heating of the occasion. Because of the large water content of food materials, heat, and therefore need to spend a considerable amount of heat. Same. When the water content of raw material is reduced by heating method, the latent heat of evaporation of water will greatly increase the consumption of energy. In addition. Because the majority of heating treatment by indirect heating way, resulting in a part of the energy dissipation and damage to the surrounding environment, therefore, must be taken into account, the operating environment of the heat recovery of sound and efficient use. In non heat treatment occasions, such as high voltage electrostatic field, for processing objects, high energy efficiency, sterilization effect and electric field strength, the high voltage energy consumption is not high, less consumption of energy in the process of operation.
