Embodiment 1

[0027] After crushing, Jiangxiang sieves through a 40-mesh sieve, add 10-15 times of water, stir and soak for half an hour; add the volatile oil extractor to boil for 4 hours, collect the volatile oil from the lower end of the measuring device; add anhydrous sodium sulfate to the volatile oil Remove moisture. Prepare a 50°C homogeneous aqueous solution with a ratio of 25% of gum arabic and maltodextrin at a ratio of 5:5, add 12% of the core and wall material ratio of the volatile oil of Rhizoma chinensis, and stir evenly. Pass the emulsion through an ultrasonic cell crusher with a duty cycle of 5s-5s and work 60 times to emulsify the homogeneous emulsion. Stir the water bath at 60 °C for 4 h. The microcapsule powder is dried and collected by a spray dryer. The spray drying inlet air temperature is 220°C, and the outlet air temperature is 120°C.

Abstract

The invention provides a preparation method of Mosla chinensis essential oil microcapsules. The method comprises the following steps: drying Mosla chinensis, crushing, and extracting Mosla chinensis essential oil by adopting a water steam distillation process; preparing a certain concentration of an aqueous solution of Arabic gum and maltodextrin, adding the above Mosla chinensis volatile oil, homogenize-mixing uniformly, and stirring in a water bath at a certain temperature; and carrying out spray drying by using a spray drying instrument to obtain Mosla chinensis volatile oil microcapsule particles. The method has the advantages of simplicity, feasibility, and easy control of preparation conditions; and the obtained microcapsule particles have the advantages of good quality of the Mosla chinensis volatile oil, good thermal stability and dissolving dispersibility, uniformity, good fluidity and special smell of the Mosla chinensis volatile oil. The Mosla chinensis volatile oil capsules can be widely applied in the industries of foods, medicines, cosmetics and the like, and has a wide application range.

Description

technical field [0001] The invention relates to oil processing technology, in particular to the processing of the volatile oil of Jiangxiangrui. Background technique [0002] Herbs ( Herba Moslae ) also known as Banbiansu[ E. ciliata (Thunb) Hyland ], usually refers to the labiatae plant Shixiang ( Mosla chinesis Maxim ) or Jiang Xiangru ( Mosla chinensis "jiangxiangru" ) dry aerial parts. Spicy and sweet in taste, warm in nature, non-toxic. It is recorded in "Famous Doctors", "Picture Herbal Classic", and "Compendium of Materia Medica" in ancient my country. Jiangxiang is an authentic medicinal material in Jiangxi with a long history of cultivation. It is mainly distributed in Xinyu City, Zhangshu City, Fenyi County, Yushui District and other places. In summer, when the stems and leaves are luxuriant and the flowers are in full bloom, choose sunny days to harvest, remove impurities, and dry in the shade. It has the functions of expelling summer heat, promoting dam...
