Production method of Sinkiang quarenden crisp chips

Abstract

The invention relates to a production method of Sinkiang quarenden crisp chips. The production method comprises the following steps: performing cleaning, mechanical peeling and slicing on fresh and insect-resistant Sinkiang quarendens taken as raw materials; and performing color protection, blanching, sugar immersion, freezing treatment, primary puffing, secondary puffing, drying and cooling on the sliced Sinkiang quarendens so as to finally obtain the Sinkiang quarenden crisp chips. According to the production method of Sinkiang quarenden crisp chips, the technology of the combination of the primary puffing and the secondary puffing is adopted, so that the diffusion of water in the Sinkiang quarenden chips is accelerated; the puffing degree of the Sinkiang quarenden chips is enhanced, the drying time is shortened, the crisp degree of the Sinkiang quarenden crisp chips is improved. The primary puffing and the secondary puffing are both carried out by simultaneously performing the heating from the front end and the rear end of a heater in a puffing tank, so that the situation that materials are unevenly heated in the original puffing tank is overcome. As a result, the product yield of the Sinkiang quarenden crisp chips is improved, namely, the product yield can reach 98%; the color and the luster of the Sinkiang quarenden crisp chips are improved.

Description

technical field [0001] The invention relates to a production method of Xinjiang red apple chips, belonging to the technical field of food processing. Background technique [0002] Xinjiang red apple (Plumleaf crab), also known as red crabapple fruit, also known as catalpa, sea red, etc., belongs to the genus of apple in the family Rosaceae. Contains sugars, multi-vitamins and organic acids, and has a strong aroma of fresh crabapple, which can help replenish the intracellular fluid of the human body, thus having the effect of promoting body fluid and quenching thirst; the content of vitamins, organic acids and tannins in crabapple fruit is relatively rich, and can It helps the stomach and intestines to digest food, and has the effects of lightening the body and losing weight, opening the spleen and strengthening the stomach, so it can be used to treat indigestion, food accumulation, and abdominal distension; crabapple tastes sweet and slightly sour, sweet can slow down, acid ...

[0005] Chinese patent CN100407946C (application number: 200510042975.1) announces a method for producing puffed apple crisps or dices by microwave-pressure difference process. The processing steps for producing apple crisps or dices from fresh apples are: material preparation, cleaning, peeling and peeling. Nuclei, slices or cubes, enzyme inhibition, color protection, thermal dehydration, microwave pre-expansion, conditioning, pressure difference puffing, cooling; Chinese patent CN1111014C (application number: 99106580.8) announced a production method of low-temperature vacuum puffed fruit and vegetable chips. The method includes steps such as slicing, color protection, dehydration, low-temperature puffing, and shaping, and realizes puffing at low temperature. The puffed fruit and vegetable chips preserve the original flavor of the fruit and vegetable, and concentrate the nutrients, vitamins, and minerals of the fresh fruit. and trace elements; however, there is no follow-up process for fruit and vegetable chips puffed by the above method. After high-temperature puffed fruit and vegetable chips, the hot steam gathers in the fruit and vegetable chips. Under negative pressure, the hot steam in the fruit and vegetable chips The fruit and vegetable chips cannot be dispersed, and the fruit and vegetable chips after cooling and drying have shrinkage, deformation or even distortion, which affects the appearance of the product. In addition, the steam distribution in the fruit and vegetable chips is not uniform, and the dried fruit and vegetable chips are relatively hard and not crispy. ;It is only puffed once, and the moisture is discharged at high temperature, resulting in a decrease in the puffing degree of the puffed product

Existing expansion tank comprises steam generator, instrument electric gas control cabinet, vacuum pump, air compressor, vacuum tank, expansion tank, heater and cooling system, and its volume design of said vacuum tank is at least 5 times greater than the volume of expansion tank The expansion tank is equipped with a multi-layer heater inside, and the heater is a multi-layer tubular structure. When heating, steam is injected into the heater through a steam generator. The existing heating method is from the rear end of the heater. The hot steam is introduced to heat, so that the temperature inside the expansion tank rises. When the hot steam is transmitted from the rear end of the heater to the front end, the heat loss leads to a lower temperature at the front end of the heater, and the uneven temperature between the front and rear leads to uneven heating of the material. Affect the color of the material, and the product yield is relatively low
