Technical Field

The invention relates to the field of health-care food, in particular to a production process of high-grade black brown sugar.

Background

The brown sugar is crude sugar prepared by taking sugarcane as a raw material and carrying out juice extraction, clarification, boiling and crystallization, and completely keeps the original flavor and nutrient substances of the sugarcane. Brown sugar is used as a sweetener in China and is regarded as a health-care product from ancient times to present.

However, the main components of the brown sugar are sucrose and reducing sugar, and the total sugar content (sucrose content + reducing sugar content) of the top-grade brown sugar in GB/T35885 & 2018 & ltbrown sugar & gt is more than or equal to 90.0 percent; meanwhile, the requirement of drying weight loss is less than or equal to 4.0 percent. The total sugar only provides energy to human body, and has no other nutrition and health care value. Therefore, the effective components of the brown sugar are mainly derived from other substances of about 6 percent.

Other substances in brown sugar mainly include the sugar cane itself contains: colloid, fiber, xylose, and small amount of crude fat, starch, inorganic salt, vitamins, protein, amino acids, etc., which can be obtained normally by diet. Meanwhile, the brown sugar also contains a small amount of melanoidins and Maillard reaction intermediates (reducing ketone substances and heterocyclic compound components) generated by Maillard reaction in the production process of the brown sugar, and the melanoidins and the Maillard reaction intermediates are also main sources of the fragrance, the color and the efficacy of the brown sugar.

Melanoidins are reaction products of a compound having a hemiacetal hydroxyl group (aldehyde, reducing sugar) and a compound having an amino group, which are condensed and polymerized to form a high molecular weight polymer. The Maillard reaction was first discovered by Maillard, a famous chemist in france, in 1912, when heated with a mixed solution of glycine and glucose. The melanoidin has the effects of resisting oxidation, promoting iron absorption, inhibiting bacteria, reducing blood pressure, reducing blood sugar, resisting allergy, resisting mutation, protecting cardiovascular health and the like, and is also a main source of the efficacy of the brown sugar.

As shown in figure 2, the production process of the common brown sugar is shown, the prepared brown sugar has less melanoidin components, the melanoidin content is 1-3%, and the brown sugar has low health care effect on human bodies.

Therefore, the preparation of brown sugar with high content of melanoidin is urgently needed.
