By adding nano aluminum oxide and utilizing the high adsorptivity of the nano aluminum oxide to adsorb essence microcapsules, the fragrance of the fragrance candle can be slowly released during combustion, and the fragrance durability of the fragrance candle is improved.
As preferable: a fragrance candle, which comprises the following raw materials in parts by weight: 85-95 parts of soybean wax, 28-33 parts of natural beewax, 17-19 parts of plant essence microcapsule, 1.5-2.5 parts of polyethylene wax and 2-4 parts of nano alumina.
The fragrance candle raw materials can be selected from 85-95 parts of soybean wax, 28-33 parts of natural beeswax, 17-19 parts of essence microcapsules, 1.5-2.5 parts of polyethylene wax and 2-4 parts of nano alumina, any value in the respective range can be selected, and the fragrance durability of the fragrance candle can be improved.
As preferable: the essence microcapsule is prepared by the following operation steps:
adding 1-2kg of hydroxypropyl beta-cyclodextrin into 2-4kg of deionized water, adding 0.3-0.5kg of soy protein isolate, uniformly mixing, adding 0.3-0.4kg of emulsifying agent, homogenizing, adding 0.06-0.1kg of plant essence at 30-50 ℃, mixing, homogenizing, spray drying, solidifying and hardening to obtain essence microcapsule.
By adopting the technical scheme, the hydroxypropyl beta-cyclodextrin is added into deionized water to be fully dissolved, then the soybean protein isolate is added to be uniformly mixed, so that the compactness and film forming property of the wall of the plant essence microcapsule can be improved, the embedding efficiency of the hydroxypropyl beta-cyclodextrin embedded plant essence is improved, the emulsifying agent is added to carry out emulsification and homogenization, the plant essence is added to be mixed after homogenization, the homogenization is carried out to embed, and the essence microcapsule with a shell-core structure is obtained by spray drying, and finally the essence microcapsule is obtained by solidification and hardening.
The essence microcapsule wall obtained by the application has higher compactness and film forming property, can prevent the volatilization loss of the fragrance of the plant essence, and has higher embedding efficiency.
As preferable: the emulsifier is a mixture of sodium caseinate and potassium dihydrogen phosphate.
By adopting the technical scheme, the mixture of sodium caseinate and potassium dihydrogen phosphate is selected as the emulsifier, and the sodium caseinate has higher emulsifying property and water retention, can be used as a wall material and an emulsifier, and can improve the stability of hydroxypropyl beta-cyclodextrin and soy isolate protein. The potassium dihydrogen phosphate is added to be mixed with the sodium caseinate, so that the viscosity of the sodium caseinate is increased, the strength of an emulsion film is increased, and emulsion drops are prevented from being combined, so that the stability of the emulsion is improved.
As preferable: the mass ratio of the potassium dihydrogen phosphate to the sodium caseinate is 1: (0.5-1).
By adopting the technical scheme, the stability of the emulsion can be further improved by adjusting the mass ratio of the monopotassium phosphate to the sodium caseinate, so that the embedding efficiency of the essence microcapsule is further improved, and the fragrance persistence of the fragrance candle is further improved.
