Longan whole powder having high sugar content and low viscosity and preparation method thereof

Abstract

The invention discloses longan whole powder having high sugar content and low viscosity. The longan whole powder having high sugar content and low viscosity is prepared from 35 to 55 parts by weight of longan pulp, 6 to 26 parts by weight of soybean meal, 15 to 35 parts by weight of a soyabean protein, 22 to 44 parts by weight of maltodextrin and 0 to 2 parts by weight of cane sugar powder. The invention also discloses a preparation method of the longan whole powder having high sugar content and low viscosity. The longan whole powder having high sugar content and low viscosity is rich in longan pulp, has low viscosity, comprises uniform powder, and has good fluidity, good reconstituability and a good taste.

Description

technical field

[0001] The invention relates to a longan whole powder and a preparation method thereof, in particular to a high-sugar and low-viscosity longan whole powder and a preparation method thereof. Background technique

[0002] Longan has been cultivated in my country for more than 2,000 years, and the current planting area is about 460,000 hm 2 , with an annual output of about 940,000 tons, accounting for 73% and 59% of the world's total respectively, and its cultivated area and output rank first in the world. Longan fruit has a unique flavor and high nutritional value, and has various physiological health functions such as improving immunity, anti-aging, anti-tumor, and promoting intellectual development. Longan mature season is hot and humid, its fruit skin is thin and juicy, high in sugar but low in acidity, so it is easy to rot and deteriorate after harvest. At present, in China, only about 20% of longan is consumed as fresh fruit after harvesting, and the res...
