Problems solved by technology

[0005] To sum up, the main problems in the current soybean tea processing technology are: (1) The processing raw materials are all reprocessed products of cultivated soybeans such as cultivated soybeans or soybean powder, soybean germ, soybean extract, etc. The cultivated soybeans have large grains and low fat content. High, low content of soybean isoflavones, high edible value, but the medicinal or health value is lower than that of wild soybeans; (2) The processing method is still mainly steaming and frying, the processing time is long, and the nutritional components of soybeans are seriously damaged
So far, there are no patents or publications at home and abroad that use wild soybean grains as the main raw material to develop tea products

Embodiment 1

[0038] A processing method for improving the quality of wild soybean tea, comprising the following steps: placing wild soybean grains harvested in the same year in hot water (>95°C) three times the weight, soaking for 4 hours, stirring once every 2 hours during this period, and cooling naturally ;Put the soaked wild soybean grains in a germination box, accelerate germination at a constant temperature of 25°C for 30 hours until the bud length is 6mm, during this period, pour water every 5 hours for 30 seconds; place the accelerated wild soybean grains in a blast drying box , dry at 60°C for 28 hours until the water content of the grains is below 8%; place the dried wild soybean grains in an automatic roaster and bake at 140°C for 25 minutes until the skin of the grains cracks; place the roasted wild soybean grains in a dry In a room (the relative water content of the air is less than 15%), after cooling to room temperature, weigh, and pack and seal with aluminum foil bags.

Embodiment 2

[0040] A processing method for improving the quality of wild soybean tea, comprising the following steps: placing the wild soybean grains harvested in the current year in hot water (>95°C) three times the weight, soaking for 3 hours, and stirring once every 1.5 hours during this period, and naturally Cooling; put the soaked wild soybean grains in a germination box, accelerate germination at a constant temperature of 25°C for 24 hours until the bud length is 4mm, during this period, water once every 4 hours, and the watering time is 30s; place the wild soybean grains after germination in a blast drying box inside, dry at 70°C for 24 hours until the moisture content of the grain is 6%; place the dried wild soybean grains in an automatic roaster and bake at 150°C for 20 minutes until the skin of the grains cracks; place the roasted wild soybean grains in a dry In a room (the relative water content of the air is less than 15%), after cooling to room temperature, weigh, and pack and...

Embodiment 3

[0042] A processing method for improving the quality of wild soybean tea, comprising the following steps: placing wild soybean grains harvested in the same year in hot water (>95°C) three times the weight, soaking for 3.5 hours, stirring once every 1.75 hours during the period, Cool naturally; put the soaked wild soybean grains in a germination box, germinate at a constant temperature of 25°C until the bud length is 5mm, during this period, water once every 4.5h, and the watering time is 30s; place the wild soybean grains after germination in blast drying In the box, dry at 65°C until the moisture content of the grain is 6% to 8%; put the dried wild soybean grain in an automatic roaster, bake at 145°C for 22 minutes until the skin of the grain cracks; put the roasted wild soybean grain Place in a dry room (the relative water content of the air is less than 15%), cool to room temperature, weigh, and pack and seal with an aluminum foil bag.

Abstract

The invention discloses a processing method for improving the quality of glycine soja tea. According to the method, glycine soja is used as a raw material. The glycine soja tea is obtained through the sequantial steps of performing soaking with hot water, performing constant-temperataure sprouting, performing low-temperature drying, performing quick baking, performing cooling and packaging, and the like. According to the processing method disclosed by the invention, the glycine soja is used for making tea initiatively, and a conventional processing technology is optimized, so that not only are the unique flavor and the nutrient components of the glycine soja reserved, but also the hygienic quality and the nutrient quality of the glycine soja are improved; and the processing procedure is simplified, the processing cost is low, the processing method is convenient to popularize, and a new way is provided for the protection and the utilization of seed resources of the glycine soja.

Description

technical field [0001] The invention belongs to the field of tea product processing methods, in particular to a processing method for improving the quality of wild soybean tea. Background technique [0002] Wild soybean (Glycine soja Sieb. et Zucc) is a herbaceous plant of the leguminosae family Glycine L. and the direct ancestor of cultivated soybean (Glycine max (Linn.) Merr). The most intuitive difference between wild soybeans and cultivated soybeans is the size and color of the kernels. Wild soybean seeds are small, 81.1% of wild soybean populations have a hundred-grain weight less than 2.5g, while cultivated soybeans have a hundred-grain weight of 18g-30g. The grain color of 75.5% of the wild soybean population is black or dark brown, and the grain color of cultivated soybean is mostly yellow (soybean), and there are also black (black soybean or black soybean), cyan (green soybean or green soybean), brown, red or bi-color. [0003] In the process of domesticating wil...
