Method for removing fishy smell of spirulina with quercetin

Abstract

The invention relates to a method for removing fishy smell of spirulina with quercetin. The method comprises the following steps of (1) weighing spirulina powder, adding distilled water which is 50-100 times of the spirulina powder, stirring the spirulina powder and the distilled water, and performing treatment with a colloid mill; (2) performing enzymolysis with cellulase and pectinase, wherein the temperature is 25-42 DEG C, and the action time is 1.5-3h, performing enzyme deactivation treatment, and performing filtration; (3) adding ethanol to enzymatic hydrolysate, adding the quercetin, and performing vibration at 40-45 DEG C for 1-2h; and (4) adding maltodextrin, and performing spray drying. The quercetin can remove the fishy smell of the spirulina, the spirulina is treated with the colloid mill and enzymes, after spirulina walls are destroyed, fishy-smell substances in the spirulina are sufficiently released, and the quercetin is added, so that the fishy smell of the spirulina can be effectively eliminated.

Description

technical field [0001] The invention relates to some fishy smell removal methods, in particular to a method for removing the fishy smell of spirulina with quercetin. Background technique [0002] Spirulina belongs to a class of lower organisms. It has survived on the earth for 3.5 billion years. It is the earliest photosynthetic organism on the earth. It grows in water, and its shape can be seen under a microscope as a spiral filament, so it gets its name. Spirulina is widely cultivated all over the world and is often used as a dietary supplement due to its rich nutrition and outstanding efficacy. The main components of spirulina are protein, carbohydrates and fat. The protein content of spirulina dry powder is as high as 60%, mainly composed of glutamic acid, isoleucine, leucine, lysine, methionine, phenylalanine, threonine amino acid, tryptophan, valine, etc., and its amino acid composition is very reasonable; Spirulina polysaccharide is the main form of carbohydrates in ...

[0003] Then spirulina has a special fishy smell, and many people who need to take it give up taking it because they can't bear the fishy smell

In the prior art, some people use the method of breaking the wall or fermentation to remove the fishy smell, and then the effect of removing it is not ideal, and the steps are complicated. The breaking of the wall requires a homogenizer, and the fermentation method is very harsh on the fermentation conditions. Different species are fermented, and the effect of removing fishy smell is also different, resulting in poor product balance
