Embodiment 1

[0018] 100 grams of rosin and 0.05 grams of palladium-carbon catalyst were added to the hydrogenation reaction kettle successively, and then hydrogen was introduced. The hydrogen pressure in the kettle was controlled to be 3 MPa, and the reaction temperature was controlled to 220 ° C. The reaction was performed for 6 hours, and the palladium-carbon catalyst was filtered and removed to obtain 100 grams of hydrogenated rosin; then add 9.1 grams of glycerol and 0.03 grams of zinc oxide to 100 grams of hydrogenated rosin, control the reaction temperature to 280° C., and react for 4 hours to obtain hydrogenated rosin glyceride.

[0019] Comparative test 1: 100 grams of rosin was heated and dissolved, then 9.8 grams of glycerol and 0.03 grams of zinc oxide were added, the reaction temperature was controlled to 280°C, and the esterification reaction was carried out for 4 hours to obtain rosin glyceride.

Embodiment 2

[0021] 500 grams of rosin and 0.4 grams of palladium-carbon catalyst were successively added to the hydrogenation reaction kettle, and then hydrogen was introduced. The hydrogen pressure in the kettle was controlled to be 4 MPa, and the reaction temperature was controlled to 260 ° C. After 4.5 hours of reaction, the palladium-carbon catalyst was filtered and removed to obtain 500 grams of hydrogenated rosin; then add 68 grams of glycerol and 0.25 grams of zinc oxide to 500 grams of hydrogenated rosin, control the reaction temperature to 275° C., and react for 3 hours to obtain hydrogenated rosin glyceride.

[0022] Comparative test 2: 500 grams of rosin was heated to dissolve, then 68 grams of glycerol and 0.25 grams of zinc oxide were added, the reaction temperature was controlled to 275°C, and the esterification reaction was carried out for 3 hours to obtain rosin glyceride.

Embodiment 3

[0024] 1000 grams of rosin and 0.8 grams of palladium-carbon catalyst were successively added to the hydrogenation reaction kettle, and then hydrogen was introduced. The hydrogen pressure in the kettle was controlled to be 4.5 MPa, and the reaction temperature was controlled to 230 ° C. The reaction time was 4.5 hours, and the palladium-carbon catalyst was removed by filtration. , to obtain 1000 grams of hydrogenated rosin; then add 106 grams of glycerol and 0.7 grams of zinc oxide to the hydrogenated rosin, control the reaction temperature to 275 ° C, and react for 3 hours to obtain hydrogenated rosin glyceride.

[0025] Comparative test 3: 1000 grams of rosin was heated and dissolved, then 106 grams of glycerol and 0.7 grams of zinc oxide were added, the reaction temperature was controlled to 275°C, and the esterification reaction was carried out for 3 hours to obtain rosin glycerol ester.

Abstract

The invention discloses a preparation method of hydrogenated rosin glyceride, which comprises the following steps: adding a rosin and a palladium-carbon catalyst into a reaction kettle, introducing hydrogen gas to carry out addition reaction to obtain the hydrogenated rosin, sequentially adding glycerol and zinc oxide, and carrying out esterification reaction to obtain the hydrogenated rosin glyceride. The hydrogenated rosin glyceride has the advantages of light color, no peculiar smell, favorable mouthfeel, chewing resistance, favorable foaming property and favorable plasticity, and can be used instead of food-grade rosin glyceride as a chewing gum bodying agent in bubble gum, chewing gum, gum, sugar-free gum and other products.

Description

technical field [0001] The invention relates to the technical field of deep processing of rosin, in particular to a preparation method of hydrogenated rosin glyceride. Background technique [0002] Edible-grade rosin glyceride is a gum base agent, which can impart foaming, plasticizing, and chewing properties to gum. It is often used in bubble gum, chewing gum, chewing gum, sugar-free chewing gum and other products. Food grade rosin glyceride is obtained by esterification of rosin and glycerol, and then vacuum-treated to make irregular transparent block, flake or granular solid. [0003] The traditional preparation method of edible-grade rosin glyceride is to dissolve the rosin and then add glycerol and a catalyst to carry out an esterification reaction to obtain rosin glyceride. The introduction of the product requires corresponding impurity removal steps, which leads to the extension of the process and ultimately increases the production cost. Therefore, a product with h...
