Embodiment 1

[0041] Clean the raw peach gum, remove bark, soil and other impurities, soak it with clean water to make it fully swell, add a sodium hydroxide solution with a pH value of 10, beat it into a slurry with a beater, and place it at 80°C for 2 Hours, the hydrolyzate was decolorized with 3% hydrogen peroxide solution. The peach gum hydrolyzate was passed through 001 * 7 After desalting the cation exchange resin, dry it in an oven at 80°C to obtain peach gum powder. Dissolve peach gum powder in deionized water to prepare 20% peach gum solution. Use 3% (w / w) sodium hydroxide solution to adjust its pH value to 8.5, place it in a constant temperature water bath box at 35°C, slowly add octenyl succinic anhydride to the solution, and the addition amount is peach gum dry base 5% (w / w) of the amount, and the solution was stirred for reaction. Pass the reacted solution through 001 * 7 Cation exchange resin, to exchange sodium ions and hydrogen ions in the solution, and then pass through...

Embodiment 2

[0043] Clean the raw peach gum, remove bark, soil and other impurities, soak it with clean water to make it fully swell, add a sodium carbonate solution with a pH value of 9, grind it into a slurry with a beater, and place it at 85°C for 5 Hours, the hydrolyzate was decolorized with 2% sodium hypochlorite solution. After the peach gum hydrolyzate is desalted with D001 cation exchange resin, adjust its pH value to 9.0 with 3% (w / w) ammonia water, place it in a constant temperature water bath at 45°C, and slowly add octenyl amber to the solution The acid anhydride is added in an amount of 1% (w / w on a dry basis) of the amount of peach gum, and the solution is stirred for reaction. The solution after the reaction is passed through the D001 cation exchange resin to exchange the sodium ion and the hydrogen ion in the solution, and then pass through the AB-8 macroporous resin to remove the remaining octenyl succinic anhydride and octenyl succinic acid in the solution, thereby A pur...

Embodiment 3

[0045]Clean the raw peach gum, remove bark, soil and other impurities, soak it with clean water to make it fully swell, add an ammonia solution with a pH value of 11, use a beater to grind it into a slurry, and place it at 95°C for 4 hours , the hydrolyzate was decolorized with 3% sodium sulfite solution. The peach gum hydrolyzate was desalted with D201 cation exchange resin, and dried in an oven at 65°C to obtain peach gum powder. Dissolve the peach gum powder in deionized water to prepare a 30% peach gum solution. With 3% (w / w) NaHCO 3 The pH value of the solution is adjusted to 8.5, placed in a constant temperature water bath at 35°C, and octenyl succinic anhydride is slowly added to the solution in an amount of 3% (w / w on a dry basis) of the amount of peach gum, stirred The solution reacts. Pass the reacted solution through D201 cation exchange resin to exchange sodium ions and hydrogen ions in the solution, and then pass through D1300 macroporous resin to remove the re...

Abstract

The invention discloses a making method of octal-olefin succinic peach-gel ester, which comprises the following steps: adopting original peach gel, octal-olefin succinic anhydride as raw maerial; hydrolyzing original peach gel; esterifying; removing impurity in the esterifying liquid; dehydrating; drying to obtain the product with cutting-proof force and emulsifying stability.

Description

technical field [0001] The invention relates to the modification of natural products, in particular to a method for preparing peach gum octenyl succinate with peach gum and octenyl succinic anhydride as raw materials. Background technique [0002] At present, my country's beverage industry is developing vigorously, especially acidic protein beverages, which are rich in nutrition, good in flavor, high in safety, low in production cost, and easy to invest. They are welcomed by consumers and investors and have a huge market and development potential. However, quality problems such as stratification, flocculation and precipitation are prone to occur after the acidic protein drink is left for a period of time, which reduces the market competitiveness of the product. At present, a more effective method is to use stabilizers such as emulsifiers and thickeners to increase its stability, but there are not many stabilizers that can be used for acidic protein drinks. Inexpensive, stab...
