Method for preparing nitroso hemoglobin pigment easy to disperse and high in thermal stability

Abstract

The invention discloses a method for preparing nitroso hemoglobin pigment easy to disperse and high in thermal stability, and belongs to the technical field of nitroso hemoglobin pigment preparation. The method comprises the following steps: by taking ox blood as a raw material, purifying and decontaminating so as to prepare conventional nitroso hemoglobin pigment, further by taking a kudzuvine root as a raw material, crushing with a hammer, washing, collecting a kudzuvine root starch turbid liquid, standing, collecting starch slurry, compounding with hemoglobin pigment and amino acid, performing thermal treatment, wrapping, and performing freeze-drying crushing, thereby obtaining the nitroso hemoglobin pigment easy to disperse and high in thermal stability. Practical tests show that the method disclosed by the invention is unique and novel; when nitroso hemoglobin is used as a substitute of nitrite, not only is the residual amount of nitrite in a meat product reduced and is damage to human bodies reduced, but also a livestock blood resource can be sufficiently utilized, the blood resource can be developed and utilized, the iron content is increased, low-saltpetre or saltpeter-free meat products can be made indeed, and the food security is improved.

Description

technical field [0001] The invention discloses a preparation method of easily dispersible and highly thermally stable nitrosohemoglobin pigment, which belongs to the technical field of nitrosohemoglobin pigment preparation. Background technique [0002] my country's meat food industry is an emerging industry developed since the reform and opening up, and occupies an important position in the food industry. According to statistics, my country's total meat output has reached 62 million tons per year, ranking first in the world and accounting for the world's meat. 28.9% of the total. At present, the average meat production in the world accounts for 10% to 20% of the meat production, and the meat production in some developed countries accounts for 60% to 70% of the total meat production, but there is still a big gap between my country and this ratio. There are only more than 2 million tons of deep-processed meat products in my country every year, accounting for 4% of the total m...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: in view of the poor thermal stability of the current nitrosohemoglobin in the preparation process, precipitation occurs immediately after heating at 75°C, and it is no longer soluble in water, and the nitrosohemoglobin pigment is in the air or under light conditions. And the color of the meat products added with this pigment is unstable and fades quickly. Even after microcapsule embedding, the stability is not improved and the dispersibility is poor. It provides a kind of raw material that uses bovine blood as a raw material, through purification and removal of impurities. The traditional nitrosohemoglobin pigment is prepared, and pueraria root is used as raw material by hammering, and the pueraria starch suspension is collected by washing, and the starch slurry, hemoglobin pigment and amino acid are compounded after being collected by standing, heat-treated, coated, freeze-dried and pulverized, so that Preparation method for obtaining easily dispersible high thermal stability nitrosohemoglobin pigment
