Extraction Technology of Pectin from Watermelon Peel

Pectin Extraction Pectin is a thickener and stabilizer commonly used in food processing. The content of pectin in watermelon peel is rich and it is a good raw material for pectin extraction. The following is the extraction technique of pectin in watermelon rind. 1? Raw material cleaning: Use fresh, non-rotated watermelon rind to remove sediment and clean it. 2? Steam: In order to kill the pectinase in living cells, put the washed melon into a steamer, steamed until the melon becomes soft, and the water is precipitated and dripped. 3? Pressing: The steamed rind into the bag squeezed, squeezed as much as possible, remove the water in the tissue cells and dissolved in the sugar, inorganic salts and other substances, in order to increase the purity of pectin. 4? Hydrolysis: Put the dried ingredients in a corrosion-resistant container, add 3-4 times the amount of water to the rind, add acid to adjust the pH to about 2, and heat to 98-100°C for a certain period of time. This step should master the acidity, temperature and time. If the acidity is large and the temperature is high, it takes a short time; otherwise, the pectin will be excessively hydrolyzed; if the acidity is small and the temperature is low, it takes a long time; otherwise, the pectin hydrolysis Not out. 5? Filtration: Use a bag to filter, collect the filtrate, and perform a second hydrolysis of the filter residue.
6? Second hydrolysis: filter residue plus 2 times water, with appropriate amount of acid to adjust the PH value of about 2, using the above method and then hydrolyzed and filtered once, discarded the filter residue, the two combined filtrate. 7. Decoloration: Add 0.3-0.5% of activated carbon to the filtrate, decolorize at 55-60°C for 30 minutes, and collect the filtrate. 8? Concentration: The decolored liquid is vacuum concentrated to a solids content of 8%. 9? Alcoholysis: Add 90% ethanol to the concentrate, using 2 times the concentrate. When ethanol is added, pectin can be observed to be flocculated and squeezed after the pectin is completely flocculated. 10? Pressing: The flocculent pectin is placed in a fine cloth bag to remove the liquid. 11. Alcohol wash: The squeezed pectin was washed with 5% ethanol and then the ethanol was squeezed. 12? Drying: The solid pectin is placed in an enamel plate and baked at a temperature of 65-75C until the moisture content drops below 8%. 13? Crushing: The dried solid pectin is ground and crushed in a dry environment, and the pectin finished product is obtained after passing through a 60-mesh sieve.
