preparation example Construction

[0022] The invention provides a kind of preparation method of walnut kernel bean curd skin, comprises the following steps:

[0023] (1) Mix walnut kernels with iron oxide particles, put them into a high-speed mixer to stir and mix, then discharge and separate the iron oxide particles and pretreated walnut kernels through a magnetic separator, and place the pretreated walnut kernels Dry it under vacuum and low temperature conditions, then put it into water, and stir it immediately. During the stirring process, the skin of the walnut kernel is continuously removed, and then it is refined to obtain the original walnut kernel solution, and then filtered through a filter to obtain the walnut kernel juice ;

[0024] (2) screening the soybeans, removing impurities and bad beans, soaking in water, refining, and filtering to obtain soybean milk;

[0025] (3) Take the soybean milk prepared in step (2) and add it to the boiling tank, heat it to 95°C; add the walnut kernel juice prepared...

Embodiment 1

[0040] A preparation method for walnut kernel bean curd skin, comprising the following steps:

[0041] S1: Mix walnut kernels and iron oxide particles with an average particle size of 0.05mm at a weight ratio of 1:0.03, then add them to a high-speed mixer for stirring and mixing at a stirring speed of 200r / min; then discharge and pass through magnetic separation The machine separates the iron oxide particles from the pretreated walnut kernels, and the iron oxide particles are recovered for next use;

[0042] Dry the pretreated walnut kernels under the condition of vacuum degree of 0.30Mpa and temperature of 40°C for 50 minutes, then add 4 times the amount of water, stir immediately, and continuously remove the walnut kernels during the stirring process epidermis;

[0043] Then control the weight ratio of walnut kernels to water to 1:3, grind to obtain walnut kernel stock solution, and then filter through a filter to obtain walnut kernel juice;

[0044] S2: Screen the soybean...

Embodiment 2

[0050] The preparation method of the walnut kernel bean curd skin as provided in Example 1, the difference is that the peeling process of the walnut kernel in the present embodiment is different from embodiment 1; specifically, the preparation method of the walnut kernel bean curd skin comprises the following steps:

[0051] S1: Dry the walnut kernels for 50 minutes at a vacuum of 0.30Mpa and a temperature of 40°C, then add 4 times the amount of water and stir immediately, and continuously remove the skin of the walnut kernels during the stirring process ;

[0052] Then control the weight ratio of walnut kernels to water to 1:3, grind to obtain walnut kernel stock solution, and then filter through a filter to obtain walnut kernel juice;

[0053] S2: Screen the soybeans to remove impurities and bad beans, then soak the soybeans in water at 20-25°C for 7 hours; control the weight ratio of soybeans to water to 1:4, refine the pulp, and filter to obtain soybean milk;

[0054] S3:...

Abstract

The invention belongs to the technical field of bean product deep processing, and specifically relates to a preparation method of a walnut kernel bean curd sheet. The preparation method comprises thefollowing steps: (1) pretreating walnut kernels; (2) screening soybeans to get rid of impurities and bad soybeans, and adding water to carry out soaking, defibrination and filtration so as to obtain soybean milk; (3) adding the soybean milk into a cooking barrel and heating to 95 DEG C, adding walnut kernel juice under a condition of slow stirring and heating to 105-110 DEG C, and preserving the heat for 20 min to obtain walnut kernel and soybean milk mixed solution; (4) pouring the walnut kernel and soybean milk mixed solution into a bean curd sheet forming pot to carry out heat preservationand forming; (5) naturally drying the formed bean curd sheet so as to obtain the walnut kernel bean curd sheet. According to the preparation method, skins of the walnut kernels are removed to preventthe bitterness of the skins and prevent the skins from affecting the forming in the bean curd sheet forming process, so that the bean curd sheet forming efficiency is ensured; through addition of thewalnut kernels in the bean curd sheet, the nutritional ingredients of the bean curd sheet is further enriched and the taste of the bean curd sheet is improved.

Description

technical field [0001] The invention belongs to the technical field of deep processing of bean products, and in particular relates to a preparation method of walnut kernel bean curd skin. Background technique [0002] Yuba, also known as bean curd skin, is made by heating soybean milk to boil, and after a period of heat preservation, a layer of film is formed on the surface, which hangs down into branches after being picked out, and then dried. Its shape is similar to bamboo branches, and it is called yuba. Yuba has high nutritional value, is easy to preserve, and is convenient to eat, and is deeply favored by consumers at home and abroad. [0003] Walnut kernel is the pulp in the walnut core, also known as walnut kernel and walnut meat. Walnut kernels have multiple nutritional functions. Among them, as a tonic of high-fat substances, walnut kernels have direct antibacterial and anti-inflammatory effects; at the same time, the rich oil in walnut kernels is beneficial to mo...
