Method for preparing rhodomyrtus tomentosa particle instant solid beverage based on superfine grinding technology

Abstract

The invention relates to a method for preparing a rhodomyrtus tomentosa particle instant solid beverage based on a superfine grinding technology. The method comprises the following production steps: firstly, selecting and cleaning a fruit, washing the rhodomyrtus tomentosa fruit by using clean water, and draining; secondly, drying, namely, drying the rhodomyrtus tomentosa fruit in a blast drying oven, and transferring the dried rhodomyrtus tomentosa fruit to a vacuum drying box for drying continuously; thirdly, grinding, namely, performing primary grinding on the rhodomyrtus tomentosa fruit to obtain coarse powder, and performing superfine grinding on the coarse powder to obtain superfine whole fruit powder; fourthly, blending and uniformly mixing main and auxiliary materials of rhodomyrtus tomentosa particles; fifthly, preparing a soft material and granulating through the prepared mixed material; sixthly, drying again, namely, tiling prepared wet particles on a baking tray for drying; finally, sizing by adopting a 20-40-mesh screen to obtain a rhodomyrtus tomentosa particle solid beverage product. The rhodomyrtus tomentosa particle instant solid beverage has the characteristics of convenience in preparing, safety, hygiene, convenience in storage and transport, and the like.

Description

technical field [0001] The invention belongs to the technical field of fruit deep processing, and relates to a method for preparing gangren granule instant solid beverage based on ultrafine pulverization technology. Background technique [0002] Gang Ren ( Rhodomyrtus tomentosa (Ait.) Hassk), is the fruit of myrtle plant Myrtle, also known as Shanren, Dangli, Renzi, Doumin, Zhongni, Wudu, Uncle Tao, Dangni, Myrtle. Plants are born in hillsides, fields, hills and roadside shrubs, and are widely distributed in the mountainous areas of Jiangxi, Fujian, Guangxi, Guangdong and Yunnan provinces in my country. Gangren fruit is non-toxic and non-polluting. It is purple-red because it is rich in anthocyanin phytochemicals. It is a pure natural wild small berry with good color, country and taste and rich nutrition. It is estimated that only the mountainous areas in northern Guangdong have an annual output of 50,000 to 80,000 tons of Gangren fruit. Because the ripening period of Gan...

Problems solved by technology

The water content of fully mature Gangren fruit is about 74%, rich in pectin, and the juice yield is only about 30%. If it is spray-dried, it will not only cost more, but also cause waste of raw materials
