Embodiment 1

[0137] The production method of walnut powder of the present invention is as follows:

[0138] ①Material selection: select walnut kernels that are plump, free from insects, mildew, and oil, and remove walnut shells and impurities;

[0139] ②Peeling: use the walnut kernel to contain 0.1% CaCl 2 Soak it with 0.5% NaOH composite lye for 5 minutes, the immersion temperature is 60~63℃, and the dosage of composite lye is 4 times the weight of walnut kernels. After soaking, spray with a 0.3Mpa high-pressure and small-flow clean water gun and combine with bubbling water jet impact Combined with three-effect ultrasonic vibration for washing and peeling, ultrasonic vibration power≥2000W, time 5min;

[0140] ③Centrifugal dehydration: the dehulled walnut kernels are subjected to centrifugal dehydration;

[0141] ④Drying: Put the peeled walnut kernels in a vacuum drying oven at a temperature of 48~50℃ and a pressure of 0.07Mpa, and dry until the moisture content is about 5%;

[0142] ⑤Crushing: Use...

Embodiment 2

[0151] The production method of walnut powder of the present invention is as follows:

[0152] ①Material selection: select walnut kernels that are plump, free from insects, mildew, and oil, and remove walnut shells and impurities;

[0153] ②Peeling: use the walnut kernel to contain 0.1% CaCl 2 Soak in 0.5% NaOH composite lye for 3 minutes at a temperature of 60-63°C. The amount of composite lye is 4 times the weight of walnut kernels. After soaking, spray with a 0.5Mpa high-pressure and small-flow clean water gun and combine with bubbling water jet impact Combined with three-effect ultrasonic vibration for washing and peeling, ultrasonic vibration power≥2000W, time 3min;

[0154] ③Centrifugal dehydration: the dehulled walnut kernels are subjected to centrifugal dehydration;

[0155] ④Drying: Put the peeled walnut kernels in a vacuum drying oven at a temperature of 48~50℃ and a pressure of 0.07Mpa, and dry until the moisture content is about 5%;

[0156] ⑤Crushing: Use a crusher to crus...

Abstract

The invention provides walnut powder and a production method thereof; walnut kernel is peeled by high pressure water spraying, bubble water stream impact and ultrasonic wave vibration after being soaked by compound alkaline liquid, and then second-grade cold pressing is carried out to the peeled walnut kernel after the peeled walnut kernel is dried and crushed, the walnut kernel is crushed, filtered, batched and colloid-milled to be refined, and then a complex stabilizer is added in the walnut kernel to be sterilized, concentrated, homogenized and dried to obtain the walnut powder. The method has low damage degree, can effectively prevent protein denaturation and reduce alkaline liquid amount; the second-grade cold pressing technology is adopted, the denaturation degree of the protein of the walnut cake is reduced, and the walnut powder is prepared by high-pressure homogeneity and spraying drying; the visual color and luster, solubility and the content of the protein and other indexes of the product are superior to the similar products in the current market. The invention realizes the comprehensive utilization of the walnut resource, the technology is advanced, simple and practical and is easy to popularize, thereby having good economic and social benefits.

Description

Technical field [0001] The invention relates to walnut powder and a production method thereof. Background technique [0002] At present, walnut processed products in my country are mainly walnut kernels, and walnut kernels have low added value and are prone to oily deterioration at room temperature, which is not conducive to balanced production. Therefore, the development of walnut deep processing products is an urgent requirement for the development of my country's walnut industry. Walnut powder is a deep-processed product of walnut kernels with high nutritional value. At present, the production process of walnut powder on the market is mostly ultra-fine powder and micro-grinding. The product produced by this process has large hardness, poor solubility, easy precipitation, and low purity. Bacteria production, the bacterial index exceeded the standard. [0003] The invention overcomes the shortcomings of the prior art and provides a walnut powder and a production method thereof. ...
