48 results about "Cochineal" patented technology

The cochineal (/ˌkɒtʃɪˈniːl/ KOTCH-ih-NEEL, /ˈkɒtʃɪniːl/ KOTCH-ih-neel; Dactylopius coccus) is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America through North America (Mexico and the Southwest United States), this insect lives on cacti in the genus Opuntia, feeding on plant moisture and nutrients. The insects are found on the pads of prickly pear cacti, collected by brushing them off the plants, and dried.

Method for extracting chitin and chitin thereof

The invention provides a method to extract a chitin by utilizing the residue of a cochineal insect from which a haematochrome is already extracted and a chitin prepared by the method. The chitin extraction method comprises: 1) the residue of the cochineal is hydrolyzed and the protein is deprived, 2) the inorganic salt inside the residue is removed and a crude product of the chitin is derived from the residue, 3) an oxidant is added into the crude product of the chitin to do the oxidation and the decoloration process. The extraction method is characterized in that taking use of the residue of the cochineal from which the haematochrome is extracted as a raw material with simple process and easy operation, the prepared chitin appearance color and lustre and physiochemical index are in accordance with the standards for the food, medicine, cosmetics, agriculture, and environment protection, and the prepared chitin by the method is possessed of high purity and low ash content. The extraction and preparation method of the chitin from the residue of a cochineal insect has the advantages of utilizing comprehensively the resource, achieving the purpose of full use of the whole cochineal insect, decreasing the environmental pollution, and improving the economic profit for the enterprises.

Method for little-water dyeing of cotton fabric by cochineal color

The invention belongs to the technical field of a natural dye dyeing method, and concretely relates to a method for little-water dyeing of cotton fabric by cochineal color. The method comprises the following steps: a) preparing finishing liquid: taking chitosan, adding acetate acid gracial, stirring the materials to obtain the chitosan diluted finishing liquid; b) cotton fabric treatment: immersing the cotton fabric according to bath ratio of 1:30 in the chitosan finishing liquid, adding a cross-linking agent, employing two dipping and padding for treatment, placing the material under acid neutralization environment, washing the material and roasting the material to obtain the chitosan-modified cotton fabric; c) dye liquor preparation: dissolving the cochineal color in an mixed solution of an organic solvent and water, stirring the materials to obtain the dye liquor; and d) dyeing: placing the chitosan-modified cotton fabric according to bath ratio of 1: 30 in the dye liquor, washing the material, and drying the material. By chitosan modification treatment of the cotton fabric, an organic solvent system is employed for dyeing, dyeing waste water discharge is reduced, water repellency of the cotton fabric is increased, and the degree of dyeing and the color fastness of the cochineal color to the cotton fabric are increased.

Method for removing fishy smell and protecting color of duck meat

The invention relates to the field of duck meat processing, in particular to a method for removing the fishy smell and protecting the color of duck meat. The method comprises the steps of removing the viscera of a duck, cleaning the duck, blanching the duck in warm water, soaking the duck in water containing purple common perilla, lemon and cassia bark, blowing air to the warm water during soaking, ensuring that a ventilating pipe extends to the bottom of the warm water, taking out the duck and soaking the duck in ice and water mixed bath, adding eucalyptus oil, tea polyphenol and chitosan into the ice and water mixed bath, taking out the duck and placing the duck into an operating chamber at the temperature of 5 to 10 DEG C, arranging a spraying device at the upper part of the operating chamber, putting the duck on a rotating frame in the middle of the operating chamber, arranging spray liquor inside the spraying device, which adopts mixed liquor of cochineal, sodium carbonate and sodium bicarbonate, freezing the processed duck in a freezing chamber, and performing vacuum package, so as to obtain duck meat without fishy smell and bright color. The method effectively removes the fishy smell of duck meat and simultaneously improves the color of the duck meat.

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.
