Embodiment 1

[0070] (1) First prepare a 15% (w / v) saturated aqueous solution of β-cyclodextrin, place it in a constant temperature water bath at 50°C and stir at a speed of 200r / min for 3 hours, then use an appropriate amount of peppermint oil as the core material, add to β-cyclodextrin In the cyclodextrin saturated aqueous solution, keep the mass ratio of peppermint oil and β-cyclodextrin at 1:4, and continue to stir for 3 hours. Filter to obtain wet capsules, and finally vacuum-dry at 40°C for 2 hours to obtain the finished mint oil cyclodextrin inclusion compound powder.

[0071] Take by weighing a certain amount of calcium chloride, Tween 80, Span 80 and xanthan gum and dissolve them in water, the concentrations are respectively 6%, 0.8%, 1.6%, 0.4% (w / v), stir until completely dissolved, then Add peppermint oil in a stirring state, fully mix the raw materials by high-speed shearing, set the rotation speed at 10000r / min, and process for 2 minutes to obtain a peppermint oil emulsion, wh...

Embodiment 2

[0081] Prepare a 15% (w / v) saturated aqueous solution of β-cyclodextrin, dissolve it in a water bath at 50°C and stir at a speed of 200r / min for a period of time, then add an appropriate amount of peppermint oil to the saturated aqueous solution of β-cyclodextrin In , mint oil cyclodextrin inclusion complexes with core-to-wall ratios of 1:2, 1:4, 1:6 and 1:8 (w / w) were prepared respectively, and the inclusion complexes were kept stirring for 3 hours. After stirring, put it in a refrigerator at 4°C and let it stand until it completely precipitates, filter the precipitate with suction to obtain a wet capsule, and finally dry it in vacuum at 40°C for 2 hours to obtain the finished peppermint oil inclusion complex powder, whose properties are as follows: Figure 4 shown.

[0082]Weigh a certain amount of calcium chloride, Tween 80, Span 80 and xanthan gum and dissolve them in water to make their concentrations respectively 6%, 0.8%, 1.6%, 0.4% (w / v), and stir until completely diss...

Abstract

The invention discloses a mint oil gel bead and a preparation method thereof, and belongs to the technical field of microcapsule technologies. The method is characterized in that the mint oil gel beadcapable of maintaining a good form in drying and storage processes is prepared respectively through optimizing and regulating the form and proportion of mint oil core materials. The method adopts thefollowing steps of preparing a mint oil cyclodextrin inclusion compound; mixing the mint oil cyclodextrin inclusion compound with mint oil emulsion according to a certain proportion; dropwise addinga mixture into a sodium alginate solution to immediately form the mint oil gel bead; then, respectively curing the mint oil gel bead in a calcium chloride solution and a chitosan acetic acid solution;next, fishing out the mint oil gel bead; performing vacuum drying to obtain a finished product. The gel bead prepared by the invention has good shaping performance in the drying process; in the storage process, the subsidence rate is low, and the stability is high; the effect of regulating the core material release rate is also achieved.

Description

technical field [0001] The invention relates to a peppermint oil gel bead and a preparation method thereof, belonging to the technical field of microcapsule technology. Background technique [0002] Peppermint oil has both antibacterial and aroma-imparting properties, and is widely used in condiment, tobacco and other industries. However, when peppermint oil is exposed to the air, it is very easy to volatilize, which also restricts its application range. In order to solve this problem, there are many reports in the prior art that peppermint oil is encapsulated and protected by microencapsulation. [0003] Gel beads are a kind of microcapsules, which are usually prepared by anionic polysaccharides such as sodium alginate and pectin and metal cations through ionic crosslinking. In order to improve the strength of the gel film, a positively charged chitosan solution can also be introduced to make it react with anionic polysaccharides to form a polyelectrolyte, giving the syste...
