Problems solved by technology

[0003] However, the tofu currently available in the market is light yellow. Making tofu into colored tofu can increase people's appetite, but the pure natural extraction color on the market is expensive. Many businesses add chemically synthesized pigments in order to save costs. Regular food can cause great harm to the human body. Therefore, there is a need for a cheap, safe and healthy tofu pigment additive, especially a green pigment additive

Embodiment 1

[0019] A preparation method of tofu pigment additive, comprising the following steps:

[0020] (1) Color protection: select fresh raw materials, clean them, chop them, evenly spray vitamin C solution with a mass concentration of 0.03%, and freeze-dry until the water content is 7-9%, so as to avoid browning of raw materials and keep the color bright green. Freeze-dry the raw materials, save the amount of ethanol, save costs, retain the nutrients in the raw materials, increase the porosity of the raw materials, promote the release of nutrients and chlorophyll, improve the extraction rate of nutrients and chlorophyll, and obtain color-protected raw materials;

[0021] (2) Rough extraction: Add absolute ethanol 50 times the weight of the color-protecting raw material to the color-protecting raw material, mix evenly, shake at 1°C and 56 rpm for 3 hours, filter, and add 30 times the weight of the filter residue to the filter residue Ultrasound at 1°C and 31kHz for 20 minutes in anhy...

Embodiment 2

[0031] A preparation method of tofu pigment additive, comprising the following steps:

[0032] (1) Color protection: select fresh raw materials, clean them, chop them, evenly spray vitamin C solution with a mass concentration of 0.04%, and freeze-dry until the water content is 7-9%, so as to avoid browning of raw materials and keep the color bright green. Freeze-dry the raw materials, save the amount of ethanol, save costs, retain the nutrients in the raw materials, increase the porosity of the raw materials, promote the release of nutrients and chlorophyll, improve the extraction rate of nutrients and chlorophyll, and obtain color-protected raw materials;

[0033] (2) Rough extraction: Add absolute ethanol 55 times the weight of the color-protecting raw material to the color-protecting raw material, mix well, shake at 2°C and 57 rpm for 3 hours, filter, and add 35 times the weight of the filter residue to the filter residue Ultrasound at 2°C and 32kHz for 20 minutes in absolu...

Embodiment 3

[0043] A preparation method of tofu pigment additive, comprising the following steps:

[0044] (1) Color protection: select fresh raw materials, clean them, chop them, evenly spray vitamin C solution with a mass concentration of 0.05%, and freeze-dry until the water content is 7-9%, so as to avoid browning of raw materials and keep the color bright green. Freeze-dry the raw materials, save the amount of ethanol, save costs, retain the nutrients in the raw materials, increase the porosity of the raw materials, promote the release of nutrients and chlorophyll, improve the extraction rate of nutrients and chlorophyll, and obtain color-protected raw materials;

[0045](2) Rough extraction: add anhydrous ethanol 60 times the weight of the color-protecting raw material to the color-protecting raw material, mix well, shake at 4°C and 58 rpm for 4 hours, filter, and add 40 times the weight of the filter residue to the filter residue Ultrasound at 4°C and 33kHz for 25 minutes in anhydr...

Abstract

The invention mainly relates to a food additive processing and discloses a method for preparing a bean curd pigment additive. The method comprises steps of color fixation, rough extraction, drying, material addition and packaging. The additive is simple in method, wide in raw material, low in price, free of toxic chemical, safe and healthy and easy to popularize, on-scale production is achieved, and the economic income of the additive is increased by 17.7% when being compared with that of a conventional pure plant extracted pigment; due to addition of vitamin C in a raw material, the raw material is prevented from browning, a bright green color is maintained, the use amount of absolute ethyl alcohol is reduced as the raw material is freeze-dried, the cost is reduced, nutrient components in the raw material are maintained, the porosity of the raw material is improved, release of nutrients and chlorophyll is promoted, and the nutrient and chlorophyll extraction rate is increased; due to addition of the in a color fixation raw material, low-temperature oscillation extraction is firstly implemented, the pigment is extracted primarily, further low-temperature ultrasonic treatment is implemented, tissue structures are sufficiently damaged, chlorophyll release is promoted, the extraction rate of the chlorophyll is increased by 8.7%, the raw materials are saved, and the cost is lowered.

Description

technical field [0001] The invention mainly relates to the technical field of food additive processing, in particular to a preparation method of a bean curd pigment additive. Background technique [0002] Tofu is one of the favorite foods in our country. It is rich in nutrition, rich in protein, flavonoids, fat and mineral elements. It can promote the growth and development of children. For the elderly, it can prevent osteoporosis, fight cancer and suppress cancer, protect cardiovascular and cerebrovascular, Eliminate free radicals and delay aging. [0003] However, the tofu currently available in the market is light yellow. Making tofu into colored tofu can increase people's appetite, but the pure natural extraction color on the market is expensive. Many businesses add chemically synthesized pigments in order to save costs. Regular food can cause great harm to the human body. Therefore, there is a need for a cheap, safe and healthy tofu pigment additive, especially a green...
