Tianjin Institute of Crop Research, Tianjin 300112, China; Tianjin Institute of Industrial Microbiology, Tianjin 300204, China)Fruit and vegetable chips are new types of convenience foods made by frying and dehydrating materials under low temperature and vacuum conditions.
Low-temperature vacuum frying technology is to fry food under low temperature conditions, so it can effectively avoid high temperature damage to the food nutrients, to a greater extent to maintain the true color and flavor of fruits and vegetables, prevent the degradation of edible oils and deteriorate the quality of human body The production of harmful substances. This technology can be used for the production of a variety of fruits and vegetables, but due to the differences in the texture of the different varieties itself, the processing technology is also different. This article mainly introduces the production and processing of apple chips.
1 raw and auxiliary materials without rot deterioration Guoguang or Red Fuji apple, maturity of 7 to 80%; palm oil; salt; citric acid; phytic acid.
4 Discussion There are some aspects that need to be gradually improved in RAPD marker technology. One of the main problems is the instability of polymorphism in the experimental process. Zhao Jiuran, Liu Xinzhi, Zhang Zhongyan and others believe that strict control of experimental conditions, consistency, and screening of primers in the course of operations should lead to repeatable and reliable selection of primers that produce clearly discernible bands or fewer abnormal bands. The result of the. RAPD also tends to produce a false band of non-genomic DNA, which can be ruled out by placing duplicate and non-template DNA controls. Although there are shortcomings in RAPD technology, it is clear that in the near future, RAPD marker technology will become a common technology in genetic breeding, making China's corn breeding work into a new era.
There are mainly two types:
- hot forged from steel billet
- cold forged from steel plate
Both types of neck rings can be marked embossed and/or engraved. The neck rings can be supplied raw or zinc plated.
