Abstract

A polyphenol-rich brown sugar production technology includes the following steps that sugarcanes without sugarcane tips and sugarcane leaves serve as the raw material, are juiced and subjected to primary impurity removal, and a raw material solution is obtained; lime milk is added into the raw material solution to adjust the pH to be 7.0-7.5, and then the mixture is heated to 80-90 DEG C to obtain a heated raw material solution; a first-stage ceramic membrane with the aperture of 50-200 nm is used for filtering the heated raw material solution, and first-stage membrane clear juice and first-stage membrane concentrated juice are obtained; a second-stage membrane with the molecular weight cut-off being 1-5 kDa is used for filtering the first-stage membrane clear juice, and second-stage membrane clear juice and phenolic-substance-enriched second-stage membrane concentrated juice are obtained, wherein the second-stage membrane concentrated juice is used for producing polyphenol-rich brown sugar. The two stages of ceramic membranes with different membrane aperture sizes are used for filtering sugarcane juice, the second-stage membrane is used for filtering the concentrated juice to produce the polyphenol-rich brown sugar, the functional components, namely phenolic substances, in the second-stage membrane concentrated juice are effectively enriched, enrichment is 4-8 times that of a traditional production technology, and quality and nutritional value of the brown sugar are improved.

Description

technical field [0001] The invention relates to the field of sugar making technology, in particular to a production technology of polyphenol-rich brown sugar. Background technique [0002] Sugarcane sugar industry is the pillar industry of Guangxi's national economy and a comprehensive industry involving the primary, secondary and tertiary industries. The production and life of nearly half of the population in the region is closely related to the sugarcane industry. main support. In recent years, due to the impact of international sugar prices, sugar prices have been falling. Coupled with high production costs, weak agricultural foundation, low degree of mechanization, single variety of industrial products, and lack of market competitiveness, Guangxi's sugar industry has come to a critical crossroads. To this end, the Guangxi District Government has issued a series of policies to promote the transformation and upgrading of Guangxi's sugar industry. Strengthen the industry...
