Embodiment 1

[0041] A method for improving the porous structure and texture of vacuum freeze-dried recombined mango crisps, comprising:

[0042] Step 1. Wash and remove the core of the mango, add vitamin C with a weight of 0.2% of the weight of the cored mango and citric acid with a weight of 0.05% of the weight of the cored mango to protect the color, then perform rough beating, and then add The mango skin dregs with a weight of 10% of the mango pulp weight and the pectin with a weight of 1% of the mango coarse pulp weight, and then the mango coarse pulp mixed with mango skin residues is placed in an ultrafine beater for beating once, and the beating process adopts Circulating water cooling ensures that the temperature of the pulp does not exceed 4°C until the particle size of the pulp is less than 80 μm to obtain a fine mango pulp;

[0043]Step 2: Place the mango fine pulp at 121°C to sterilize for 15 minutes, pour it into a fermenter after cooling to room temperature, then add a starter...

Embodiment 2

[0047] A method for improving the porous structure and texture of vacuum freeze-dried recombined mango crisps, comprising:

[0048] Step 1. Wash and remove the core of the mango, add vitamin C with a weight of 0.5% of the weight of the cored mango and citric acid with a weight of 0.1% of the weight of the cored mango to protect the color, then perform rough beating, and then add The mango skin dregs with a weight of 40% of the mango pulp weight and the pectin with a weight of 5% of the mango coarse pulp weight, then the mango coarse pulp mixed with mango skin residues is placed in an ultrafine beater for beating for 3 times, and the beating process adopts Circulating water cooling ensures that the temperature of the pulp does not exceed 4°C until the particle size of the pulp is less than 80 μm to obtain a fine mango pulp;

[0049] Step 2, put the mango fine pulp at 121°C to sterilize for 15 minutes, pour it into a fermenter after cooling to room temperature, then add a starte...

Embodiment 3

[0053] A method for improving the porous structure and texture of vacuum freeze-dried recombined mango crisps, comprising:

[0054] Step 1. Wash and remove the core of the mango, add vitamin C with a weight of 0.4% of the weight of the cored mango and citric acid with a weight of 0.08% of the weight of the cored mango to protect the color, then perform coarse beating, and then add The mango skin dregs with a weight of 25% of the mango pulp weight and the pectin with a weight of 3% of the mango coarse pulp weight, then the mango coarse pulp mixed with mango skin residues is placed in an ultrafine beater for beating for 2 times, and the beating process adopts Circulating water cooling ensures that the temperature of the pulp does not exceed 4°C until the particle size of the pulp is less than 80 μm to obtain a fine mango pulp;

[0055] Step 2, put the mango fine pulp at 121°C to sterilize for 15 minutes, pour it into a fermenter after cooling to room temperature, then add a star...

Abstract

The invention discloses a method for improving the porous structure and texture of vacuum freeze-dried recombinant mango chips, which comprises the following steps: step 1. cleaning mangoes, denucleating, coarsely pulping, adding mango peel residues into the mango coarse pulp, and carrying out wet ultrafine pulping to obtain a mango fine pulp; step 2, sterilizing the mango fine pulp, adding a leavening agent into the mango fine pulp, and fermenting; step 3, pouring the fermented mango fine pulp into a chip mold, ironing the surface of the mango fine pulp, freezing the mango fine pulp, and carrying out heating-cooling variable-temperature thawing and freezing on the mango fine pulp; and step 4, performing vacuum freeze drying on the frozen mango fine pulp. According to the invention, the hardness and crispness of the vacuum freeze-dried recombined mango chips can be improved, the drying efficiency is improved, and the problems that the recombined mango crisp chips are poor in texture, low in drying efficiency and the like are solved.

Description

technical field [0001] The present invention relates to food processing methods. More specifically, the present invention relates to a method for improving the porous structure and texture of vacuum freeze-dried recombined mango chips. Background technique [0002] Fruit and vegetable crisps have the advantages of convenience, nutrition and health, and easy to carry, and are favored by consumers. In recent years, with the maturity of vacuum freeze drying technology and equipment, vacuum frozen fruit and vegetable crisps have developed rapidly. Mango is the most productive bulk fruit in my country, and vacuum freeze drying has gradually become a green and high-quality drying method for preparing mango chips. Natural mango raw materials have the characteristics of high sugar content, dense cells, and low eutectic point. Therefore, vacuum-frozen natural mango chips are prone to collapse during drying, and the drying time is long, resulting in poor hardness and brittleness. ...
