Abstract

The invention provides a processing method of dark brown sugar, and the method comprises the following steps of: S1, peeling sugarcane, cutting sugarcane into sections, performing juicing, filtering juice, adding sucrase and maltase, adjusting conditions for enzymolysis, deactivating enzyme, and conducting filtering and concentrating to obtain concentrated sugarcane juice; S2, boiling the concentrated sugarcane juice at 150-190DEG C for 30-50min, adding brown granulated sugar, performing stirring and dissolving, conducting boiling at 190-220DEG C for 60-100min, adding stevioside, performing stirring and dissolving, and conducting boiling at 220-270DEG C for 30-60min; and S3, spreading the boiled liquid on a cold bed, neatly scribing the liquid by using a scribing tool, and packaging and selling the liquid after the liquid is completely cooled and formed. According to the method, industrial continuous production can be achieved, the problem that traditional dark brown sugar production is complex in manual operation is solved, no chemical reagent or food additive is added in the processing process, and the green safety of food is guaranteed.

Description

technical field [0001] The invention relates to the technical field of brown sugar processing, in particular to a method for processing brown sugar. Background technique [0002] Sugarcane is a kind of fruit unique to the subtropical zone. It has rich juice, high sugar content, and a sweet taste. It also contains trace elements such as calcium, potassium, iron, magnesium, folic acid and other minerals. It has high nutritional value and is beneficial to the human body. Acid-base balance, widely loved by people. Brown sugar is intended to be darker, unrefined edible sucrose, which retains most of the effective nutrients of sugarcane. At present, brown sugar in the domestic market is mainly imported from Japan and Taiwan, and there is no relevant product report in China. Guangxi is a place of sugarcane production. Utilizing superior resources to develop brown sugar products is one of the product diversification countermeasures of Guangxi's sugar industry. [0003] The tradit...
