11 results about "Sorbitol" patented technology

Sorbitol (/ˈsɔːrbɪtɒl/), less commonly known as glucitol (/ˈɡluːsɪtɒl/), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a −C(OH)H₂ group. Most sorbitol is made from potato starch, but it is also found in nature, for example in apples, pears, peaches, and prunes. It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses.

Pitaya peel-based edible packaging film and preparation method thereof

ActiveCN105419370AFull edible medicinal valueAvoid pollutionWrappersFlexible coversCellulosePolymer science
The invention provides a preparation method for a pitaya peel-based edible packaging film. The preparation method is characterized by comprising the following steps: (1) washing and stripping and slicing pitaya peels; (2) performing blanching treatment; (3) adding water and pulping to obtain pitaya peel pulp, wherein the mass ratio of matter obtained in the step (2) to the water is (15 to 45):100; (4) adding a thickening agent and a plasticizer into the pitaya peel pulp, wherein the mass ratio of the thickening agent to the pitaya peel pulp is (0 to 0.4):100, and the mass ratio of the plasticizer to the pitaya peel pulp is (0 to 0.3):100; the thickening agent is sodium alginate or sodium carboxymethylcellulose, and the plasticizer is glycerinum or sorbitol; (5) performing homogenization treatment at a treatment rate of 15000 to 20000 r / min for 5 to 8min; then, performing degassing treatment and standing to obtain shaped pulp; (6) casting and drying, and then performing film uncovering to obtain the pitaya peel-based edible packaging film. The invention also provides the packaging film prepared by the preparation method.

Culture medium and culture method for culturing haematococcus pluvialis by using brewery wastewater

InactiveCN103966103AUnicellular algaeMicroorganism based processesPhosphateMonopotassium phosphate
The invention relates to a culture medium for culturing haematococcus pluvialis by using brewery wastewater, of which the formula is as follows: 80 ml of brewery wastewater, 28 mg of sodium citrate, 20 mg of urea, 12 mg of potassium dihydrogen phosphate, 150 mg of fructose, 45 mg of yeast extract powder, 50 mg of casein tryptone, 12 mg of ammonium citrate, 25 mg of whey powder, 30 mg of lactose, 60 mg of glucose, 1.8 ml of horse manure leachate, 2 ml of fermented soya-bean milk, 100 mg of sorbitol, 24 mg of soluble starch, 25 mg of soytone, 28 mg of beta-sodium glycerophosphate, 12 mg of an edetic acid, 10 mcg of vitamin B1, 21 mcg of vitamin B1, 1.8 ml of soil extract, 1.5 ml of human urine, 2.4 ml of chicken manure leachate, and 1000 ml of pure fresh water disinfected by sodium hypochlorite. An important bioactive substance-astaxanthin can be obtained. The culture medium is low in cost, uneasily polluted, and can be reused; and due to the mixed utilization of organic fertilizers and inorganic fertilizers, the growth rate and astaxanthin content of haematococcus pluvialis are significantly increased, and the yield is increased by 270%.
