Preparation method of body painting pigment based on natural nontoxic materials

The invention relates to a preparation method of a body painting pigment based on natural nontoxic materials. The body painting pigment consists of an adhesive and pigment. The adhesive consists of the following components in parts by mass: 18 parts of gum acacia powder, 8 parts of edible glycerin, 2 parts of gelatin, 0.3 part of gellan gum, 0.2 part of xanthan gum and 71.5 parts of water; and the pigment mainly contains natural plant extracts such as black sesame melanin, maize yellow and carotene compound, natural animal extracts such as cochineal and shrimp shell pigment, microbial fermentation pigment such as phaffia color and the like. The preparation method comprises the steps of stirring the raw materials of the adhesive uniformly and then adding the pigment in a certain ratio for mixing colors uniformly to obtain the body painting pigment. The prepared pigment is natural and nontoxic, does not have stimulus to the skin, is easy to scrub (wash with water or clean with a detergent), moderate in surface drying time and good in hiding power and water tolerance, does not have organic solvent volatilization, and is environment-friendly, sanitary, safe and healthy.

Treatment process of dyeing preserved strawberries with cochineal red pigment

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.

Method and device for collecting cochineal raw material

The invention discloses a method and device for collecting a cochineal raw material. The method comprises the steps: mounting a round of sponge on the internal wall of a barrel of the cochineal raw material collecting device, carrying out power-on so as to carry out startup, enabling a long hair brush to be aligned with female adult cochineals so as to suck the female adult cochineals into a barrel body, pouring the cochineal raw material collected in the barrel body after the quantity of the cochineals collected is certain, sweeping cochineal wax attached to the wall of the barrel by a hair brush, and then, carrying out collecting again; and bagging the collected cochineal raw material with hemp bags, tightening bag necks, putting the bags in a plastic basin, rapidly irrigating the hemp bags with just-boiled scalding water so as to scald the cochineals, continuously flipping the hemp bags in the basin, then, pouring the cochineals in the hemp bags into sun-curing tools such as dustpans, carrying out spreading, and exposing the cochineals to sunshine in the sun or airing the cochineals in the shade, thereby obtaining a raw material for processing a cochineal pigment. The invention simultaneously discloses the cochineal raw material collecting device. According to the method and the device, the collection efficiency is greatly increased, a great deal of labor is saved, and the injury to human is avoided.

Preparation method of hydrophobic oleophilic cochineal red pearlescent pigment

The invention provides a preparation method of a hydrophobic oleophilic cochineal red pearlescent pigment. The method is characterized in that a hydroxy group in carmine acid molecule is esterified toprepare an oil-soluble cochineal red pigment, a mica substrate is treated with an oil-soluble cochineal red pigment colored silane coupling agent, and the novel pearlescent pigment is prepared. Compared with the prior art, the hydrophobic and lipophilic surface of the pearlescent pigment is more easily wetted by an oily solvent, dispersion of the pearlescent pigment in the environments of oily coatings, oily inks, oily cosmetics and the like can be improved, and the application fields of the pigment are greatly expanded.
