Abstract
The invention discloses a preparation method of rosin glyceride, and belongs to the technical field of deep processing of rosin. According to the invention, pine resin is used as a raw material and is prepared into rosin by virtue of the following steps: firstly, removing trace metal elements such as aluminum; then, enabling the trace metal element removed pine resin to be subjected to modified reaction with fumaric acid and water; finally, enabling the reaction product to be subjected to esterification reaction with glycerin to obtain a product, namely rosin glyceride. The method is simple in operation, mild in reaction condition, capable of effectively reducing the content of the trace metal elements such as aluminum and the like in rosin glyceride as the product, incapable of injuring human bodies and capable of being up to the standard of a food additive.
Description
Technical field
The invention belongs to rosin deep process technology field, relate in particular to a kind of preparation method of ester gum.
Background technology
Ester gum, as a kind of foodstuff additive, because it has good emulsifying property, can be used as chewy gum bodying agent, can give chewy gum and become bubble, plasticising, resistance toly the effect such as chews; For bubble gum, chewing gum, gum, sugar-free gum, there is good mouthfeel and oxidation-resistance, and keep the features such as softness; Also can in beverage, be used as emulsion stabilizer.
But, because rosin does not carry out the removal of micro-metals in preparation process, the raw material rosin that makes to buy from market, contain the micro-metalss such as aluminium generally higher, and the too high meeting of these micro-metalss causes the consequences such as brain injury, memory loss, senile dementia, this is a kind of comparatively sensitivity, affects the very strict impurity of a kind of requirement that rosin is applied in foodstuff additive.If, the rosin that these is contained to the micro-metalss such as the higher aluminium of content is prepared ester gum as one of raw material, in that product obtaining, contain the micro-metalss such as aluminium must also can be higher, and this will make its product ester gum cannot reach foodstuff additive standard-required.
Summary of the invention
The preparation method who the invention provides a kind of ester gum, the method is simple to operate, reaction conditions gentleness, and effectively reduce the Trace Metals Contents such as the aluminium of product ester gum, reach the standard of foodstuff additive.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A preparation method for ester gum, the method comprises following preparation process:
A, raw material rosin is put into acidic solution, then add wherein the Trisodium Citrate that accounts for rosin and acidic solution total mass 0.5%～1%, stir, reheat to 80 DEG C～95 DEG C and carry out insulation reaction 15min～20min, after reaction finishes, leave standstill, separate, obtain refining rosin; Wherein, the pH value of described acidic solution is 3～4, and the mass ratio of described raw material rosin and acidic solution is 1:2;
B, the rosin that fumaric acid, water are made with steps A are put into reactor and are mixed, and are then heated to 180 DEG C and carry out insulation reaction 3 hours; Wherein, the mass ratio of described fumaric acid, water and raw material rosin is 10～12:2～5:35～40;
C, until described in step B reaction finish after, in this reactor, add glycerine, mix, be then heated to 265 DEG C and carry out insulation reaction 4 hours, obtain ester gum; Wherein, the mass ratio of described glycerine and raw material rosin is 1:3.
Owing to adopting technique scheme, the present invention has following beneficial effect:
The present invention is taking rosin as starting material, first the micro-metalss such as aluminium is removed, and then carry out modified-reaction with fumaric acid, water in the process that is made into rosin, finally carries out esterification with glycerine again and makes product ester gum.The method is simple to operate, reaction conditions gentleness, and effectively reduce the Trace Metals Contents such as the aluminium of product ester gum, and can not work the mischief to human body, reach the standard of foodstuff additive.
