Embodiment 1

[0017] A production method of sunflower low-fat pectin, the production method steps are as follows:

[0018] (1) Take 10kg of crushed dried sunflower pans and soak and rinse to remove water-insoluble impurities and water-soluble pigments, and collect the filter cake through solid-liquid separation; control the temperature at 20°C for 20 minutes, and filter through solid-liquid separation equipment. Remove the filtrate, repeat the above process to make the filtrate clear and transparent, without obvious sediment;

[0019] (2)) Soak the obtained filter cake in alcohol, control the temperature at 30°C for 60 minutes, remove the fat-soluble small molecular impurities, separate it by solid-liquid separation equipment, and repeat to make the filtrate clear and transparent;

[0020] (3 Add enzyme enzymolysis: add 3 times water to the above-mentioned solid matter filter cake that collects, adjust temperature to be 40 ℃, pH be 5, add mixed enzyme, mixed enzyme accounts for 1% of filter...

Abstract

The invention provides a method for manufacturing sunflower low-fat pectins. The method comprises the following steps: (1) taking crushed dry sunflower plates, soaking and rinsing the crushed dry sunflower plates, separating solid and liquid of the crushed dry sunflower plates and collecting filter cakes; (2) adding alcohol to the obtained filter cakes so as to soak the filter cakes, controlling the soaking temperature and time, separating the solid and liquid of the soaked filter cakes through solid-liquid separation equipment, and repeatedly enabling a filter liquor to be clear and transparent; (3) adding enzyme for enzymolysis: adding water to collected substances, adjusting the temperature and pH value of the collected substances, and adding a mixed enzyme to the collected substances; (4) adding water to the obtained filter cakes, heating the filter cakes, keeping the filter cakes for a period of time, and extracting pectins from the filter cakes; (5) carrying out alcohol precipitation and solid-liquid separation on an obtained pectin solution so as to obtain pectins, adding ethanol to the pectins so as to wash the pectins, and separating the ethanol and the pectins; and (6) dissolving the pectins into the pectin solution and drying the pectin solution so as to obtain products. The method for manufacturing the sunflower low-fat pectins, provided by the invention, has the advantages of simple and convenient manufacturing process, short drying time, low cost, high product quality, good color, uniform particle size distribution and good solubility; and the impurities in the extracted low-fat pectin are completely removed.

Description

Technical field: [0001] The invention belongs to the field of natural product extraction, in particular to a production method of high-purity sunflower low-fat pectin. Background technique: [0002] Pectin is a group of polygalacturonic acid, which is a polysaccharide mixture composed of galacturonic acid, which contains many methylated pectic acids, and these methylated pectin acids are also called pectate ester acids. About 20% to 60% of the carboxyl groups in natural pectin are esterified, and the molecular weight is 20,000 to 400,000. Pectin is a kind of natural polymer compound, which widely exists in green plants and is an important component of plant intercellular substance. It is deposited in the primary cell wall and the intercellular layer, and cross-links with different contents of cellulose, hemicellulose, lignin microfibrils and some extensin in the primary wall, making various cell tissue structures hard , showing an inherent shape, and is a support material ...
