Iron-fortified Antarctic krill paste and preparation method thereof

Abstract

The invention discloses iron-fortified Antarctic krill paste and a preparation method thereof. The iron-fortified Antarctic krill paste is composed of the following ingredients: Antarctic krill meat,Antarctic krill peptide ferrous chelate, edible salt, and alkaline protease. The preparation method of the iron-fortified Antarctic krill paste comprises the following steps: preparing a main material; preparing the Antarctic krill peptide ferrous chelate; carrying out enzymatic hydrolysis and fermentation; and blending the main material with auxiliary materials. Specifically, the iron-fortified Antarctic krill paste is prepared by using the Antarctic krill meat as the main material, as well as the edible salt, flavor protease, chicken essence, Chinese prickly ash and the Antarctic krill peptide ferrous chelate as the auxiliary materials; and the processed iron-fortified Antarctic krill paste has the function of supplementing iron. The iron-fortified Antarctic krill paste is capable of improving iron absorption rate of the human body; and thus, the iron-fortified Antarctic krill paste is a nutritious aquatic condiment which is capable of supplementing iron and replenishing high-qualityproteins. Compared with Antarctic krill paste prepared by conventional preparation methods, the iron-fortified Antarctic krill paste prepared by the preparation method is lower in salt content, thickinstead of thin in texture, palatable in taste, an convenient to eat.

Description

technical field [0001] The invention relates to the technical field of Antarctic krill deep processing, in particular to an iron-fortified Antarctic krill sauce and a preparation method thereof. Background technique [0002] Iron is an essential micronutrient element for the human body, an important component of hemoglobin and myoglobin, and a component of many enzymes such as cytochrome and peroxidase, which play an important role in biological oxidation and the respiratory system, however Iron element is currently a nutrient that is widely lacking in the world. According to research data, about 25% of preschool children and 37% of non-pregnant women in the world are iron deficient. Similarly, in my country, about 39% of school-age children and 28% of pregnant women have insufficient iron intake. It can be seen that iron deficiency is a nutritional problem that needs to be solved urgently in the world and in my country. [0003] Studies have found that peptides and ferrous i...

Problems solved by technology

[0003] Studies have found that peptides and ferrous ions can form soluble chelates, making ingested ferrous ions soluble in the small intestine or carrying ferrous ions directly into small intestinal cells to promote iron absorption and reduce ferrous ions in the intestinal tract. Form insoluble precipitates with dietary factors such as oxalic acid and phytic acid, improve the bioavailability of iron, and thus meet the iron demand of the human body. At present, there is no relevant report on iron-fortified Antarctic krill paste. Nutritional aquatic seasoning supplemented with high-quality protein has important practical significance
