Embodiment 1

[0030] A kind of pretreatment method of high color value, high-quality prickly grape raw material, comprises the following steps:

[0031] Step 1: Take fresh thorn grapes, put the cleaned thorn grapes in an atmospheric steam container, and steam for 20 minutes, so that the surface temperature of the original thorn grapes reaches 70°C;

[0032] Step 2: Put the steamed thorn grapes into the air shower mechanism, one side sends air, and the other side outputs air. The air supply port is equipped with a condensing unit to cool the incoming air, and the fan blows the cold air to the thorn grapes. The wind speed is 0.25~0.3m / s, the air temperature is 0.25~0.3℃, place the thorny grapes on the air duct in the middle, and let the cold wind blow through the upper and lower planes from the side to ensure that both sides are even, and cool to room temperature;

[0033] Step 3: The thorny grape fruit obtained in step 2 is frozen by freezing equipment using gradient temperature. The gradien...

Embodiment 2

[0036] A kind of pretreatment method of high color value, high-quality prickly grape raw material, comprises the following steps:

[0037] Step 1: Take fresh thorn grapes, put the cleaned thorn grapes in an atmospheric steam container, and steam for 30 minutes, so that the surface temperature of the original thorn grapes reaches 80°C;

[0038] Step 2: Put the steamed thorn grapes into the air shower mechanism, one side sends air, and the other side outputs air. The air supply port is equipped with a condensing unit to cool the incoming air, and the fan blows the cold air to the thorn grapes. The wind speed is 5-7m / s, the air temperature is 30-35°C, place the thorny grapes on the air duct in the middle, and let the cold wind blow through the upper and lower planes from the side to ensure that both sides are even, and cool to room temperature;

[0039] Step 3: The thorn grape fruit obtained in step 2 is frozen by freezing equipment using a gradient temperature. The gradient proc...

Embodiment 3

[0042] A kind of pretreatment method of high color value, high aroma thorn grape raw material, comprises the following steps:

[0043] Step 1: Take fresh thorn grapes, place the cleaned thorn grapes in an atmospheric pressure steam container, and steam for 40 minutes, so that the surface temperature of the original thorn grapes reaches 90°C;

[0044] Step 2: Put the steamed thorn grapes into the air shower mechanism, one side sends air, and the other side outputs air. The air supply port is equipped with a condensing unit to cool the incoming air, and the fan blows the cold air to the thorn grapes. The wind speed is 1-3 m / s, the air temperature is 15-20°C, place the thorny grapes on the air duct in the middle, and let the cold wind blow through the upper and lower planes from the side to ensure that both sides are even, and cool to room temperature;

[0045] Step 3: The thorn grape fruit obtained in Step 2 is frozen by a freezing device using a gradient temperature. The gradie...

Abstract

The invention provides a pretreatment method of a high-color-value and high-quality vitis davidii raw material, and relates to the technical field of agricultural product processing. The pretreatment method comprises the following steps that step 1, fresh vitis davidii is taken, cleaned, and steamed with steam; step 2, the steamed vitis davidii is rapidly cooled; and step 3, the vitis davidii fruits obtained in the step 2 is frozen. The vitis davidii treated by the method can maintain the unique characteristics of bright rose color and strong fruit fragrance of vitis davidii fruits, and further effectively maintains nutritional ingredients of sugar, flavonoid compounds, resveratrol, vitamin C and the like contained in the vitis davidii fruits.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a pretreatment method for high-color-value and high-quality prickly grape raw materials. Background technique [0002] Thorn grape (Vitis davidiiFoex), also known as Qianjin vine and mountain grape, is a kind of wild grape of the genus Vitis, woody vine, spherical fruit, purple-red (or purple-black) skin when ripe, and a radius between 0.6 and 1.1 cm. The top of the seeds is round, and the seed extrusion is round, usually with 1 to 4 seeds. The fruit ripening period of thorn grapes is from July to October, and it is mostly produced in deep ditches and bushes in Shaanxi, Gansu, Zhejiang, Hunan, Hubei, Guangdong, Guangxi and other places. In recent years, the Hunan thorn grape industry has developed rapidly. By the end of 2020, the cultivated area has exceeded 150,000 mu, and the total output has exceeded 250,000 tons. It has become the most important fruit...
