The invention discloses a moisturizing eye mask prepared from bacterial cellulose. The method for preparing a moisturizing eye mask from bacterial cellulose comprises: inoculating 1-2 rings of activated inclined seed Gluconacetobacter xylinum into a medium, and conducting oscillating culture to obtain a seed solution; then inoculating the seed solution into the medium, fully oscillating the bacterial solution obtained by mixing the seed solution and the medium to make them mixed uniformly, then conducting stationary culture, thus generating a bacterial cellulose membrane floating on the solution surface, flushing the generated bacterial cellulose membrane with water to remove the medium and impurities on the membrane surface, then immersing the membrane in an alkali solution to remove thalli and residual medium from the membrane, and finally flushing the membrane with distilled water till the pH value of the membrane is measured up to 7-7.2, thus obtaining a bacterial cellulose wet membrane, which is then cut into an eye mask. The eye mask has the advantages of good moisturizing property and biological tissue compatibility, no toxicity, harmlessness, and simple material processing technology.

Disclosed is a method for extracting dihydro quercetin from larch. The invention is an improved production method. Due to different production materials and extraction processes, the dihydro quercetin products in U.S. and European markets are very expensive, at a price of 200-1000 euros per gram. Such a high market price economically limits the wide range of practicability of dihydro quercetin products. During the pretreatment of raw materials, 50 kilograms of larch wood chips and 500-800 liters of 50% ethanol solution are added into a reactor to get fully stirred and mixed; then the mixture is extracted and filtered for the second extraction; the filtrates are combined and adsorbed; the organic solvents are collected and dried by a vacuum evaporator through organic phase vacuum distillation; according to a weight proportion of 10:1, the residues are dissolved with hot water, decolorized with activated carbon and then crystallized at a temperature of 3-5 DEG C to precipitate the dihydro quercetin product which is then crushed after vacuum drying to finished product. The invention is used to extract dihydro quercetin from larch.

The invention discloses a color-protecting and fresh-keeping method for fresh-cut potatoes. The method includes selecting fresh or stored potatoes as the raw material, washing cleanly, peeling, cutting into chips with thicknesses of 0.5-1.0mm, adding a composite color-protecting fresh-keeping solution having the same mass with the potato chips, and soaking for 10-30min at 20 DEG C-30 DEG C; then fishing out the potato chips from the composite color-protecting fresh-keeping solution, washing cleanly with water, soaking in water at 10-150w ultrasonic power and 10-50kHz ultrasonic frequency for 10-30min of ultrasonic time; fishing out the potato chips and draining off, processing for 10-30min under the condition of subzero 0.01MPa-subzero 0.09MPa of vacuum degree; and finally taking the potato chips out of the vacuum environment and soaking immediately into an arbutin solution with the concentration of 0.05-0.3mmol/L, soaking for 5-15min, taking the soaked potato chips out and draining for 1-3min, performing decompression packaging immediately, and storing at an environment of subzero 4 DEG C to zero DEGC. The method adopts ultrasonic and vacuum cooperative processing as well as the Chinese herb extract arbutin as the color-protecting fresh-keeping agent to inhibit enzyme and microbial activities, is better in effect compared with the prior art, and ensures that various potato processed products are prevented from brown stain in a cold storage process for more than 10 days.
