Embodiment Construction

[0017] The technical solutions of the present invention will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings.

[0018] In the present invention, unless otherwise specified, all equipment and raw materials can be purchased from the market or commonly used in this industry. The methods in the following examples, unless otherwise specified, are conventional methods in this field.

[0019] (1) Pretreatment of mackerel protein: take mackerel ( Scomberomorus niphonius ) processing by-products after oil extraction, add 500mL isopropanol to 100g of material, beat it into a homogenate with a tissue masher, and then mix it at 60 o C water bath heating, reflux, extraction 6h, suction filtration, obtain filter residue, at 60 o C is vacuum-dried, pulverized by a pulverizer again, and crosses a 100-mesh sieve to obtain the degreased mackerel processing by-product protein, which is sealed and preserved for subsequent us...

Abstract

The invention relates to the technical field of biology and particularly relates to mackerel protein-sourced iron-chelating peptide and application thereof. The amino acid sequence of the mackerel protein-sourced iron-chelating peptide is Gln-Lys-Gly-Thr-Tyr-Asp-Asp-Tyr-Val-Glu-Gly-Leu. The mackerel protein-sourced iron-chelating peptide has very strong iron chelating capacity, can be applied to iron replenishers, has no toxic and side effect and is capable of promoting the absorption of iron, so that the utilization rate of processing byproducts of mackerel is increased, and technical supportis supplied for the development of novel iron replenishers; and the mackerel protein-sourced iron-chelating peptide has wide application prospects.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an iron chelating peptide derived from mackerel protein with strong iron chelating ability and an application thereof. Background technique [0002] Mackerel is an offshore pelagic fish with abundant annual output. It is not only in Zhejiang but also one of the important marine economic fish in my country. There is a special mackerel fishery in the Zhejiang Zhoushan Islands fishery. From the analysis of the utilization status of the main fishery resources in the East China Sea, it can be found that there is still potential for the development of mackerel production. According to the statistics of the Food and Agriculture Organization of the United Nations, the annual catch of Spanish mackerel in the world reached 1.49 million tons in 2015, and it is on the rise. As a kind of low-value and high-yield fish, mackerel has a slightly sour taste and relatively rough meat texture, but its ...
