Abstract

The invention relates to a kelp extractive nutrition enhancer and a preparation method thereof, which belong to the science and technology field of food. The kelp extractive nutrition enhancer is stable in product quality and rich in nutrition; and the preparation method of the kelp extractive nutrition enhancer is simple in production technology, high in yield and low in cost. The kelp extractive nutrition enhancer provided by the invention comprises the following components in percentage by weight: 25.0%-35.0% of kelp extractives, 45.0%-59.5% of protein powder, 10.0%-15.0% of maltodextrin, 2.0%-5.0% of nutrition yeast powder and 0.5%-1.0% of an antioxidant. The kelp extractive nutrition enhancer provided by the invention is reasonable in component compatibility, low in production cost, rich in nutrition ingredient, less prone to moisture absorption and caking and good in stability, and can be taken as a favorable food nutrition enhancer.

Description

technical field [0001] The invention relates to a kelp extract nutrition enhancer and a preparation method thereof, belonging to the field of food science and technology. Background technique [0002] Kelp (Laminaria japonica Aresch) is a familiar seafood that contains polysaccharides, protein, crude fiber, a variety of amino acids and iodine. The traditional usage is to shred it and dry it or decoct it in water. It is used as a general food or a cooling diuretic food or iodine-supplemented food. Due to the lack of enzymes for digesting kelp in the digestive juice in the human body, the digestion and absorption rate of kelp is extremely low. The use of acid hydrolysis technology in the modern chemical industry can only extract iodine, mannitol, and alginate from kelp. A large number of other nutrients in kelp such as Vitamins, trace elements, seaweed polysaccharides, etc. are discarded. Therefore, the comprehensive development and utilization rate of kelp is low, resulting ...
