7054 results about "Pectin" patented technology

Pectin (from Ancient Greek: πηκτικός pēktikós, "congealed, curdled") is a structural acidic heteropolysaccharide contained in the primary cell walls of terrestrial plants. Its main component is galacturonic acid, a sugar acid derived from galactose. It was first isolated and described in 1825 by Henri Braconnot. It is produced commercially as a white to light brown powder, mainly extracted from citrus fruits, and is used in food as a gelling agent, particularly in jams and jellies. It is also used in dessert fillings, medicines, sweets, as a stabilizer in fruit juices and milk drinks, and as a source of dietary fiber.

Reconstructed tobacco coating liquid component-component group chemical kitchen combination, coupling preparation, and coupling preparation process

The invention relates to a reconstructed tobacco coating liquid component-component group chemical kitchen combination, coupling preparation, and a coupling preparation process. Discarded waste tobacco leaves and stems are subjected to presoaking and enzymatic leaching or extraction to make tobacco leaf or stem enzymatically-leached/extracted solution, or tobacco leaf and stem mixed leached/extracted solution, certain components and component groups such as protein, pectin, chloride, nicotine, nitrosamines, nitrates and the like in the tobacco leaf and stem leached/extracted solution or tobacco leaf and stem leached/extracted mixture can be selectively converted, reduced or removed by combination of enzymolysis, Maillard reaction conversion, membrane separation/concentration or column separation, freeze separation, ethanol precipitation and the like, and the coupling preparation process for chemical components and component groups in the chemical kitchen, and accordingly, recombination or fitting, combination, regulation and coke reduction and harm reduction of the chemical components and component groups of the reconstructed tobacco coating liquid are achieved, quality of reconstructed tobacco is improved, and industrial technical integration and innovation on combination and coupling of the reconstructed tobacco coating liquid are realized.

Medlar and red date enzyme and preparation method thereof

The invention discloses a medlar and red date enzyme and a preparation method thereof, which belong to the technical field of enzyme preparation. Multi-strain composite fungi powder is adopted as a leavening agent; the medlar and the red date are adopted as main raw materials; dietary fiber, pectin hydrolyzate, seasoner extracting liquor, Chinese herbal medicine extracting liquor, enzyme stabilizer and other multifunctional auxiliary raw materials are scientifically compounded and modified; low-temperature processing technology such as ultrasonic cleaning, cryogenic grinding, microwave-assisted high-voltage pulse electric field processing and ultrasonic ripening are mainly adopted in the whole process, so that the natural colors, the flavor, the taste and the content of the active materials of the medlar and the red date are maintained furthest, the biological stability, the non-biological stability and the biological activity of the medlar and red date enzyme are obviously enhanced, the introduction of chemical addition agent is reduced, and the juicing rate of the medlar and the red date as well as the food safety of the enzyme are improved. Finally, the medlar and red date enzyme with high biological activity, strong stability, strong taste, flavor and appetite, long expiration date and edible safety is prepared.

Normal-temperature drinking type yoghourt and preparation method thereof

The invention discloses normal-temperature drinking type yoghourt and a preparation method thereof. The normal-temperature drinking type yoghourt comprises the following raw materials in percentage by weight: 56.6%-60% of concentrated raw milk, 1*10<6>-7*10<9>cfu/mL of a fermenting agent, 0.03-0.5% of a stabilizing agent, a proper amount of a sweetening agent and a proper amount of water, wherein the stabilizing agent is selected from one or multiple of pectin, soybean polysaccharide and gellan gum, and the percentage is the mass percent of the stabilizing agent, accounting for the total mass of the normal-temperature drinking type yoghourt. The preparation method comprises the following steps: (1) homogenizing the concentrated raw milk and milk powder and sterilizing to obtain a sterilized liquid mixture A; (2) cooling, adding the fermenting agent for fermentation, overturning a jar by back pressure, homogenizing and cooling again; (3) uniformly mixing with the sterilized liquid mixture A, adjusting the acidity, homogenizing so as to obtain a liquid mixture B, wherein the liquid mixture A comprises the stabilizing agent, the sweetening agent and the water; and (4) sterilizing the liquid mixture B. The normal-temperature drinking type yoghourt and the preparation method disclosed by the invention have the advantages that the requirements of heat treatment for the viscosity of the yoghourt and the adding amount of the stabilizing agent are effectively reduced, the obtained normal-temperature drinking type yoghourt is good in fluidity and smooth in taste and has no obvious layering condition after being stored for 6 months under the normal temperature.
