Problems solved by technology

[0003] At present, the production process of β-cyclodextrin is very mature, and it is mainly produced by enzymatic conversion method. However, in the process of production and purification, a large amount of cyclodextrin is still lost, and it is generally discarded as mother liquor, because the discarded mother liquor still contains some Cyclodextrin exists, directly discarding it will cause economic loss and cause environmental pollution

Embodiment 1

[0015] Take a glass column (the ratio of height to diameter is 10:1), plug the lower end with absorbent cotton, and tighten the catheter plug, add an appropriate amount of activated carbon particle suspension (the amount of activated carbon is 8g activated carbon / 100mL mother liquor), let it settle naturally , rinsed with deionized water, the upper end was connected to the catheter plug, connected to one end of the constant flow pump, and the other end of the constant flow pump was immersed in the cyclodextrin mother liquor (pre-adjusted to pH 4), so that it flowed into the activated carbon column evenly and slowly, and the ring The residence time of the dextrin mother liquor in the activated carbon column was 20min, during which the column temperature was controlled at 25°C, and the product was collected. Add clove oil to 500mL cyclodextrin mother liquor: 1mL clove oil in the mother liquor after decolorization by activated carbon column, stir well to make it disperse evenly, t...

Embodiment 2

[0017] Take a glass column (the ratio of height to diameter is 25:1), plug the lower end with absorbent cotton, and tighten the catheter plug, add an appropriate amount of activated carbon particle suspension (the amount of activated carbon is 10g activated carbon / 100mL mother liquor), let it settle naturally , rinsed with deionized water, the upper end was connected to the catheter plug, connected to one end of the constant flow pump, and the other end of the constant flow pump was immersed in the cyclodextrin mother liquor (pre-adjusted to pH 5), so that it flowed into the activated carbon column evenly and slowly, and the ring The residence time of the dextrin mother liquor in the activated carbon column was 15 minutes, during which the column temperature was controlled at 20° C., and the product was collected. Add clove oil to 800mL cyclodextrin mother liquor: 1mL clove oil in the mother liquor after decolorization by activated carbon column, stir well to make it disperse e...

Abstract

The invention relates to a method for preparing clove oil microcapsules employing cyclodextrin mother solution, belonging to the technical field of the preparation of clove oil microcapsules. The method comprises the following steps: using the waste cyclodextrin mother solution in the industrial enzyme conversion preparation method of beta-cyclodextrin as raw material, treating with activated carbon, selecting proper inclusion process and adopting effective ingredients such as beta-cyclodextrin and the like in the mother solution to pack clove oil which is volatile flavoring fragrancy industrial material and preparing clove oil microcapsules. Compared with the clove oil microcapsules prepared from the finished beta-cyclodextrin, the product of the invention has the similar shape and properties. The cost of the method of the invention is much lower that that of the traditional method so as to realize the effective reuse of waste and the method also reduces the pollution to the environment.

Description

technical field [0001] The invention relates to a preparation method of a clove oil cyclodextrin inclusion compound. Specifically, the clove oil cyclodextrin inclusion compound is prepared by using the residual cyclodextrin active ingredient in the cyclodextrin mother liquor and selecting an appropriate process. The invention belongs to the technical field of clove oil microcapsule preparation. Background technique [0002] Cyclodextrin is a cyclic oligomeric compound composed of more than six glucose links obtained from starch through the action of cyclodextrin glucosyltransferase. Cyclodextrin molecules are hydrophobic inside the cavity and hydrophilic outside the cavity. This unique molecular structure allows it to form supramolecular clathrates with some guest molecules or groups that match the charge, polarity, and structural properties through van der Waals forces, hydrophobic interactions, and space matching effects between host and guest molecules. Using this prope...
