How are the chips made?

Original title: How are crisps made?
potato is known as the "King of Plants" and ranks fourth among the major food crops, after wheat, corn and rice. Potatoes as the main raw materials for the production of a variety of leisure food is favored by people, such as fried potato chips, frozen potato chips, low-fat fried potato chips, baked formed potato chips, so how the potato into potato chips?
chips are mainly divided into fried potato chips and compound potato chips.
1. Fried potato chips
When selecting ingredients, pay attention to the selection of potatoes with neat shape, uniform size and uniform distribution of dry matter;
production process: raw material selection, cleaning peeling, slibbing, rinsing, treatment, bleaching, color protection, dehydration, frying, de-oiling, flavoring.
2. Composite chips
Potato composite chips are a round flakes, with potato whole powder, potato starch and grain flour as the main raw materials, fried from composite fried a casual food.
process: main material, mixing, stirring, peeling, molding, frying, de-oiling, seasoning.
although potato chips are made from potatoes, they are much hoter than potatoes because they need to go through the process of frying.
chips in the process of frying, the surface moisture will first evaporate, and then the starch began to paste, forming a messy molecular structure, so that it will not be cross-linked into a tight structure to block the internal water spillage and the entry of external grease. Potatoes are perverted stems, which contain many tube bundle tissues and some conductive tissues, which facilitate the evaporation of water and the entry of grease. Due to the difference between the moisture gradient and the fat concentration, the moisture inside the potato will spread along the surrounding fiber tissue towards the low moisture direction, i.e. the surface, and the same external grease will transfer internally. At the same time, the higher the temperature outside the potato, the greater the dehydration rate, the more oil enters, and the higher the heat of the chips.
read this, you can understand the reason for the high calories of potato chips!
