Abstract

The invention relates to the technical field of caramel pigment processing, and particularly discloses a method for preparing caramel pigment from cane molasses. The method comprises the following steps of preparing a cane molasses solution from the cane molasses, regulating a pH value to 4-6, adding a complex enzyme agent, and keeping the temperature at 40-55 DEG C for 1-1.5 hours; heating to 60-65 DEG C, adding sucrase, and keeping the temperature for 2-3 hours; raising the temperature to 85-95 DEG C and keeping the temperature for 10-15 minutes to obtain a pretreated cane molasses solution;adding chitosan and sodium carboxymethylcellulose into the pretreated cane molasses solution, stirring for 30-40 minutes, and centrifugally collecting supernate; and adding amino acid into the supernate, heating to 140-150 DEG C, keeping the temperature to react for 1-2 hours, cooling to obtain a reaction product, concentrating and drying to obtain the caramel pigment. According to the method disclosed by the invention, colloid, protein, ash and other substances in the cane molasses are removed, and the prepared caramel pigment is high in color index and good in clarity.

Description

technical field [0001] The invention belongs to the technical field of caramel pigment processing, in particular to a method for preparing caramel pigment from sugarcane molasses. Background technique [0002] Caramel pigment, commonly known as caramel color, is a natural colorant widely used in food, brewing, beverage and other industries. It occupies an important position in the food color market and is currently the most widely used food additive in the food industry. With the rapid development of the food industry, the use of caramel coloring is increasing, and caramel coloring has become an important part of many products, and its quality requirements are getting higher and higher. At present, the production of caramel pigment mostly uses sucrose, glucose and hydrolyzed sugar of starchy raw materials. Among the sugar raw materials for the production of caramel pigment, sugar cane molasses has a wide range of sources and is cheap. Cane molasses is the remaining substan...
