Abstract

The invention discloses a treatment process of dyeing preserved strawberries with cochineal red pigment. The process comprises the following steps:1, boiling strawberries, that is, boiling strawberries in boiling liquid which is obtained by adding sodium pyrosulfite and sodium chloride in water, wherein, the content of sulfur in the boiling liquid is 200 to 500 ppm, the concentration of sodium chloride is between 5 to 10 g / L; 2, preparing pigment water, that is, adding cochineal red pigment and sodium chloride into water and carrying out stirring for even mixing, wherein, the concentration ofcochineal red pigment is 0.3 g / L, and the concentration of sodium chloride is 5 to 10 g / L; 3, dyeing strawberries, that is, dyeing boiled strawberries in the pigment water for 24 hours, wherein, temperature for dyeing at first 12 hours is 65 to 90 DEG C, and temperature for dyeing at second 12 hours is 50 to 75 DEG C; 4, infiltrating sugar, that is, carrying out sugar infiltration on dyed strawberries; 5, finishing a product, that is, carrying out baking and soft tempering on strawberries after sugar infiltration. The process provided in the invention effectively overcomes the defects that cochineal red pigment is difficult to paint, makes painting uneven and has a color not brilliant enough, and enables uniformly colored and brilliant preserved strawberries by using cochineal red pigmentto be obtained.

Description

technical field [0001] The invention relates to a dyeing process of preserved fruit, in particular to a process for dyeing preserved strawberry with cochineal red pigment. Background technique [0002] At present, synthetic pigments cannot provide nutrients to the human body, and some synthetic pigments may even endanger human health. Strawberries with natural pigments are becoming more and more popular, especially in some EU countries, the use of artificial synthetic pigments is prohibited in preserved strawberries. Carmine natural pigment is a natural pigment that can be used not only in food, but also in medicine and cosmetics. It has obvious inhibitory effect on preventing DNA damage caused by carcinogenicity, and can be used in the prevention and treatment of viral diseases, cancer and AIDS. In the past, there was no cochineal red pigment used in preserved strawberries, and artificial synthetic pigments were used. [0003] Carmine pigment has high safety and natural co...
