Chinese cuisine in the atmosphere of fresh packaging fresh preservation principle:

17 Jul 2018

 1, what is the compound atmosphere of fresh packaging? The principle of composite air-conditioning packaging is to use compound fresh air on the Chinese box has been loaded into the box of air replacement, change the box within the gas ratio, the formation of the box within the micro-atmosphere - that is, the formation of the Micro-atmosphere, so as to slow down the surface of Chinese food oxidation and microbial propagation speed, thereby extending the Chinese dishes of the shelf life and shelf life.    2, air-conditioned fresh gas generally by the carbon dioxide (CO2), nitrogen (N2) and a small amount of special gas composition. The mechanism of fresh energy preservation is to control the oxidation and enzymatic reaction of the product through hypoxia, and to inhibit the propagation speed of microorganisms through hypoxia and high carbon dioxide. The total number of initial bacteria is controlled by environmental control and workshop management, combined with temperature control So ...

What are the main requirements for the selection of fruits and vegetables packaging materials?

17 Jul 2018

1. maintain the proper concentration of oxygen and carbon dioxide: according to the physiological characteristics of different fruits, choose the appropriate film packaging bag. The fruit is sealed in a plastic bag, if the film bag or poor ventilation, respiratory intensity of fruit is too large, the oxygen concentration in the bag is too low (<3%), the fruit will produce anaerobic respiration, resulted in the accumulation of ethanol, acetaldehyde and other volatile compounds, odor and odor, reduce fruit flavor quality. In addition, high carbon dioxide concentrations (>10%) can also cause damage to certain fruits. Such as bananas and cherries can tolerate relatively high CO2 levels, while peaches, plums and citrus are sensitive to low oxygen and high carbon dioxide. The recently developed high permeable microporous membrane enables the concentration of oxygen and carbon dioxide in the bag to be between 5%--15%, which is conducive to the packaging of products with greater respirat...

When buying paper cups should pay attention to the following aspects

17 Jul 2018

   Recently, the General Administration of Quality Supervision issued a selection of disposable paper cups convenient tips, made a one-time paper cups easy to use, low prices, is the first choice for guests.

All kinds of food preservation period (for reference)

17 Jul 2018

   Fresh fruit and vegetable mushroom    Fruit and vegetable harvest, still maintain the absorption of CO2 from the CO2 metabolism of respiratory activity. Such as the reduction of O2 content in the package and the increase of CO2 content, the fruit and vegetable can maintain a weak aerobic breathing without anaerobic respiration. The aging process of fresh fruits and vegetables is delayed and the metabolic rate is reduced, thus prolonging the shelf life. Fresh fruits and vegetables in the atmosphere of fresh air from the O2, CO2 and N2 composition. Adjustable packaging season according to fruit and vegetable varieties and fresh to determine, such as strawberries, mushrooms, lychee, peach, leafy vegetables and so on. The shelf life at 0-4 ° C is 15-45 days. Using a low barrier film.    Cooked food products    Chinese and Western food and poultry cooked food products, Lu Cai, cooking, stew, fast food and other cooked food products preservation, preservation and preservation of preservat...

How should we decide?     I believe there are many food manufacturers will be more or less encountered such a situation, in the use of plastic food packaging bags packaging products after the overall surface of the curling, bag distortion, packaging is not flat, causing these problems the main reason What should we solve?    First of all to say that the packaging caused by curling, deformation, etc. The main reason:    1, the surface of the substrate film heat resistance is poor;    2, the composite process of composite substrate tension control improper control, resulting in its aging stereotypes still have residual stress, especially when the composite film thickness is more prone to such failure;    3, the thickness of the composite film is inconsistent;    4, the cooling is not sufficient;    5, ripening time is not enoug...
