Embodiment 1

[0026] 1.1 Preparation of camphor essential oil microcapsules:

[0027] (1) Take modified starch, maltodextrin and monoglyceride, add distilled water, stir in a 60°C water bath until completely dissolved, and slowly add camphor tree essential oil after cooling to room temperature;

[0028] (2) Use a high-speed disperser to mix and emulsify twice: the first time at a rotating speed of 6000 r / min for 10 min, and the second at a rotating speed of 4000 r / min for 10 min to form an emulsion;

[0029] (3) spray drying the emulsion (spray drying feed rate 18ml / min, inlet air temperature 180°C, outlet air temperature 90°C) to obtain camphor essential oil microcapsules.

[0030] 1.2 Single factor test

[0031] In the above preparation steps, the addition amount of modified starch (2%, 7%, 12%, 17%), maltodextrin (2%, 7%, 12%, 17%), the addition amount of monoglyceride (0%, 0.1%) , 0.2%, 0.4%) three factors on the encapsulation rate of camphor essential oil. When studying the influenc...

Abstract

The invention discloses a camphor tree essential oil microcapsule and a preparation method thereof, the camphor tree essential oil microcapsule comprises a core material and a wall material, the core material is camphor tree essential oil, and the wall material is a mixture of modified starch and maltodextrin. Comprising the following steps: (1) taking modified starch, maltodextrin and monoglyceride, adding distilled water, stirring in a water bath of 60 DEG C until complete dissolution, cooling to room temperature, and slowly adding camphor tree essential oil; (2) mixing and emulsifying twice by using a high-speed dispersion machine to form an emulsion; and (3) carrying out spray drying on the emulsion to obtain the camphor tree essential oil microcapsule. The camphor tree essential oil microcapsule prepared by the invention is high in embedding rate, and can well protect the functional components of the camphor tree essential oil; the particle size distribution is uniform, and the solubility and dispersity of the essential oil are improved; the stability is good, the slow release performance is good, and the storage and use time of the essential oil can be effectively prolonged. The preparation method has the advantages of convenience in production, low price, more preserved functional components, good dispersity, high stability, excellent slow release performance and the like.

Description

technical field [0001] The invention relates to the technical field of microcapsules, in particular to a camphor tree essential oil microcapsule and a preparation process thereof. Background technique [0002] Camphor tree (Cinnamomum camphora (L.) Presl.) is an important economic tree species and green tree species in China, and it is widely distributed in southern regions. It is also one of the natural spice tree species in my country, and essential oils can be extracted from its roots, stems, leaves, fruits and other parts. Camphor essential oil mainly contains important natural ingredients such as iso-nerolidol, borneol, linalool, camphor, eucalyptol, caryophyllene, α-pinene, etc. It is an important raw material for food, condiment, spice essence, medicine, chemical industry, etc., and has broad application prospects. [0003] Camphor essential oil has good biological activity, but because its main active components are alcohols and olefins, two major types of compound...
