Embodiment 1

[0012] The tea seed meal with a tea saponin content of 0.8% is subjected to primary selection to remove impurities such as soil, sand, and moldy parts; then it is put into a pulverizer to pulverize to obtain the tea seed meal with a 40 mesh sieve. Weigh 57g of crushed camellia seed meal, sterilize it in a high-temperature sterilization pot at 121°C for 40 minutes, and then use the raw material brewing method to make wine. The process conditions are fermentation temperature 33°C, fermentation time 14d, initial pH 4.0, and koji material ratio 0.8%. The added amount of acid protease is 15U / mL, the ratio of material to water is 1:2.8, the alcohol content of the wine obtained from the tea-camellia seed dregs with raw materials reaches 9.37%, the wine aroma is outstanding, and the protein content in the distiller's grains is as high as 28.34%. It shows that the alcohol content of the wine made from tea seed meal through raw material brewing is relatively high, and the wine quality is ...

Embodiment 2

[0014] The tea seed meal with a tea saponin content of 0.6% is subjected to preliminary selection to remove impurities such as soil, sand, and mildew; then it is pulverized in a pulverizer to obtain tea seed meal with a 40 mesh sieve. Weigh 53g of crushed camellia seed meal, sterilize it in a high-temperature sterilization pot at 121°C for 40 minutes, and then use the raw material brewing method to make wine. The process conditions are fermentation temperature 33°C, fermentation time 16 days, initial pH 4.2, and koji material ratio 1%. The added amount of acid protease is 20U / mL, the ratio of material to water is 1:3.2, the alcohol content of the wine obtained from the tea-camellia seed dregs with raw materials reaches 10.63%, the wine aroma is outstanding, and the protein content in the distiller’s grains is as high as 30.28%. It shows that the alcohol content of the wine made from tea seed meal through raw material brewing is relatively high, and the wine quality is better.

Abstract

A method for manufacturing wine with camellia oleifera seed dregs belongs to the technical field of agricultural products processing technology. The method decontaminates, smashes and sterilizes the camellia oleifera seed dregs with the content of tea saponin below 1% to manufacture wine through raw material wine manufacturing technology. With the alcohol content and relative flavor matter content in finally manufactured wine as indexes, parameters of the wine manufacturing technology are confirmed by optimizing factors of fermentation temperature, fermentation time, initial pH (potential of hydrogen), the ratio of yeast and materials, the ration of the materials and water and the like. The fermentation temperature is20 to35 DEG C, the initial pH is 3.6 to 5, the ratio of the yeast and the materials is 0.6% to 1.5%, addition amount of acidic protease in 10 to 24U / ml, the ratio of the materials and the water is 1 to 2.5-5, and the fermentation temperature is 8 to 16d. The wine made of the camellia oleifera seed dregs through the raw material wine manufacturing technology is considerable in alcohol content, reasonable in proportion of alcohol, acid and ester in the wine and outstanding in bouquet. The method widens application ranges of the camellia oleifera seed dregs and enables resource of the camellia oleifera seed dregs to be fully used.

Description

Technical field [0001] The invention is a method for preparing wine from camellia seed meal, belonging to the technical field of agricultural product processing. Background technique [0002] Camellia seed meal is a by-product of the extraction of camellia oil from camellia seed. With the continuous expansion of the planting area of ​​camellia and the development of tea oil processing technology, the output of camellia seed meal has increased rapidly. Camellia seed meal is rich in protein, sugar, crude fiber, ash and tea saponin, which has important development value in the fields of feed, pesticide, chemical industry, fertilizer, medicine and so on. However, most of the oil tea seed meal is currently only used for the extraction and purification of tea saponin, with a single purpose, which is far from developing the value of the oil tea seed meal. [0003] Different from ordinary oil meal, the starch content of camellia seed meal is very high, reaching about 40%, which can be use...
