The apple is a plant of Malus of Maloideae of RosaceaeThe fruit is rich in various vitamins, enzymes and more dietary fibers, and has the effects of regulating metabolism of a human body, reducing fat absorption, enhancing memory, promoting development of the human body and the like. Apple is one of four fruits in the world, and the apple cultivation area in 2021 years (200 ten thousand hm) in China 2 ) And the yield (4100 ten thousand) accounts for more than 50 percent of the world, is the world maximum producing country of apples, and the total consumption of apples in China accounts for one third of the world total consumption of apples, and is also the world maximum consuming country of apples. Along with the improvement of the living standard of people and the change of the living style and the consumption concept, diversified apple products can better meet the requirements of consumers.
In recent years, apple crisp chips are rapidly extruded into rows and columns of puffed products, have the characteristics of crispness, rich fragrance and the like, and are deeply popular with modern young people. The apple slices are well received by consumers due to the characteristics of convenient eating, easy storage and good taste. However, the apple slices sold in the market at present are mainly prepared by processes of freeze-drying (existing fruit slices are easy to soften when meeting air), naturally drying in the sun (poor in taste and easy to be contaminated by impurities) and the like, and polyphenol oxidase of fresh apple pulp can contact with the air in the processing process of the apple slices, enzymatic browning can occur quickly, so that the appearance, flavor and nutritional value of the product are deteriorated, the commodity value of the product is seriously influenced, and the like. In order to improve the quality of the apple crisp chips, people pay attention to how to solve the browning phenomenon in the drying process of the apple crisp chips.
Therefore, the problem to be solved by the technical personnel in the field is to provide the apple crisp chips which have crisp taste and low oil content and can keep the original flavor.
Disclosure of Invention
In view of the above, the invention provides apple crisp chips and a preparation method thereof, the processing of the apple crisp chips comprises two important stages of enzyme deactivation and drying, the enzyme deactivation can reduce and deactivate the activity of oxidases, and protect the nutrient substances and flavor in apples, and the hot air drying overcomes the defects of deepening color, bitter taste, high oil content and the like of the traditional fried crisp chips, and simultaneously protects the nutrient components in the apples better, thereby achieving the aims of nutrition, health, high quality and low price pursued by people.
In order to achieve the purpose, the invention adopts the following technical scheme:
