Abstract

The invention discloses a chitosan flocculant and a preparation method thereof. The chitosan flocculant is prepared from chitosan and food-grade strong phosphoric acid, wherein the dosage ratio of the chitosan to the food-grade strong phosphoric acid is 1000mg: 20 to 100mL. The preparation method comprises the steps of adding the chitosan into the food-grade strong phosphoric acid, stirring to completely dissolving, and obtaining the chitosan flocculant. The chitosan flocculant provided by the invention is simple in preparation method and convenient to use, can realize sugar cane juice clarification at low temperature, and is low in energy consumption; both the chitosan and the food-grade strong phosphoric acid have a clarification function, so that a clarification effect is good; an original flavor and nutrient substances of sugar cane juice cannot be influenced, and the original flavor and the nutrient of the sugar cane juice can be better maintained, so that the obtained sugar cane juice has high quality.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a chitosan flocculant and a preparation method thereof. Background technique [0002] In recent years, with the change of people's consumption concept and the development of beverage production technology, the popularity of using stem-like plants to make beverages has risen rapidly. With the reputation of "blood fruit" and "tonifying medicine", sugarcane juice drinks are favored by consumers. In industrial production, sugarcane juice is usually obtained from sugar factories. Unclarified sugarcane juice contains a large amount of impurities such as colloids, ash, and muddy insolubles, making it turbid. Therefore, sugarcane juice clarification is an important part of the sugar production process. The first process is also one of the keys to the quality of sugarcane juice beverages. At present, sugarcane juice clarification processes are usually divided into: lime method...
