The invention relates to an industrialization production technology for extracting ginkgolic acid from Ginkgo testa. The technology comprises the following steps: leaching Ginkgo testa; separating, concentrating and fractionating leaching extracts; adjusting a pH value of the concentrated liquid; isolating a crude extract of ginkgolic acid; crystallizing, recrystallizing, and decolorizing by alkali liquor and acid precipitation; and further purifying the ginkgolic acid. The invention employs acid solution to regulate the pH value of the solution containing ginkgolic acid, and precipitates the ginkgolic acid by a common ion effect. The technology has the advantages of simple process, convenient operation, low cost, high extraction rate and high extraction purity, can rapidly extract ginkgolic acid in large amount from Ginkgo testa, and is suitable for requirements of industrial production.

The invention provides a method for processing pickled seawater fish with grain and wine. The method includes the following steps of pretreatment of seawater fish, cleaning, combination of alkaline water treatment and ultrasonic treatment for fishy smell elimination, pickling, dehydration, pickling with grain and wine, vacuum packaging and disinfection. The fishy smell and redundant fat of seawater fish are eliminated through alkaline water and ultrasonic waves, so that the product quality is improved, wherein the alkaline water is obtained through electrolysis. A vacuum pickling mode is adopted, so that pickling efficiency is greatly improved. The seawater fish is soaked and treated in a ClO2 solution, so that the good disinfection and preservative effect is achieved. The seawater fish is coated with natural antioxidant tea polyphenol, so that the good bacteriostat preservation effect is achieved.

The invention relates to a preparation process of antibiotic refreshing linear low density polyethylene film master batch, which uses LLDPE as carrier resin, adds with lanthanum oxide, zirconium phosphate loaded with silver, zirconium phosphate loaded with zinc, oleamide, silica dioxide, octadecanoic acid monoglyceride and oxidized polyethylene, and is prepared through dispersing by coating, modifying interface, mixing material and extruding and pilleting, wherein LLDPE is 40-49 parts by weight, lanthanum oxide is 10-15 parts by weight, zirconium phosphate loaded with silver is 8-12 parts by weight, zirconium phosphate loaded with zinc is 10-13 parts by weight, oleamide is 0.5-1.2-0 parts by weight, silica dioxide20-25 parts by weight, octadecanoic acid monoglyceride is 0.4-0.8 parts by weight and oxidized polyethylene is 1.2-1.8 parts by weight. Master batch which is prepared by the process is added in LLDPE resin according to the proportion of 4-5%, and the air permeable quantity isincreased 2-3 times compared with refreshing film with same thickness after prepared into film through film blowing molding, and the film is used to the refreshing package of fruits and vegetation, which can inhibit the generation of surface microbe, reduces fruit and vegetation from decaying, and prolongs refreshing time 15-45 days.

The invention discloses a lemongrass mixed fruit juice drink with a function of nourishing the stomach and a preparation method of the fruit juice drink. The preparation method comprises steps as follows: lemongrass is subjected to impurity removal, cleaned and air-dried at the room temperature in a dark place; then, the air-dried lemongrass is crushed, and a crushed material is obtained; the crushed material and distilled water are mixed in the mass ratio being 1:(5-10) and stirred, and a pre-extracting solution is obtained; the pre-extracting solution is boiled and filtered, filtrate is collected, and a lemongrass extracting solution is obtained; papaya, mangoes, grape and apple flesh are mixed, juiced, homogenized and filtered, and mixed fruit juice is obtained; the lemongrass extracting solution, the mixed fruit juice and honey are mixed, kept at the temperature of 80 DEG C for 20 mins and immediately cooled to 4 DEG C, and the lemongrass mixed fruit juice drink with the function of nourishing the stomach is obtained. The product is prepared with the simple preparation method, is low in cost and has healthcare functions including stomach nourishing and the like and has high market value.
