Abstract

The invention discloses a preparation method of squid water-soluble melanin chelated calcium salt. Aiming at the technical problem that squid natural melanin is poor in solubility and cannot be fullychelated with inorganic calcium salt in a solution system, the invention constructs an integrated technology system containing a technology integrating ultrasonic cavitation and melanin chelation, a centrifuge nanofiltration membrane separation technology and a spray drying technology, so that the squid water-soluble melanin chelated calcium salt is prepared, has mild reaction conditions and controllable quality, and is suitable for large-scale production. The prepared squid water-soluble melanin chelated calcium salt is concentrated in average relative molecular mass, good in solubility, highin bioavailability, high in safety and free of toxic and side effects, and can be applied to the field of health foods.

Description

technical field [0001] The invention belongs to the technical field of deep processing of aquatic products, and in particular relates to a preparation method of squid water-soluble melanin chelated calcium salt. Background technique [0002] Calcium is an essential mineral nutrient for the human body. Calcium plays a very important role in all stages of human growth. Calcium deficiency leads to a variety of health risks, including osteoporosis, high blood pressure, colon cancer, obesity, kurtoise, and convulsions in children. Children, pregnant women, and the elderly are especially affected. Among China's 1.3 billion population, there are various degrees of calcium deficiency, and among them, 320 million people suffer from serious calcium deficiency. Such a huge market has spawned a large number of calcium supplement products, and new brands are constantly added. So far, more than 500 calcium preparation products have been circulated in the market around the world. These c...
