Embodiment 1

[0030] Formula and preparation of nano-microcapsule preservative (1)

[0031] 1. Add 3 g of nano-SiO 2 Dissolve in 1L of distilled water, then add 10g of sodium alginate and 2g of konjac gum, put the prepared solution in a constant temperature water bath, bathe in a constant temperature water bath at 70°C for 20 minutes, stir to make it completely dissolve, after cooling, make up the remaining water, A composite wall material is prepared.

[0032] 2. Add 6 g of ginger essential oil and 3 g of monoglyceride to the prepared composite wall material, stir magnetically for 20 minutes, and homogenize the emulsion under high pressure for 3 times at a homogenization pressure of 35 MPa. After homogenization, the nano-essential oil microcapsule preservative is obtained.

Embodiment 2

[0034] Formula and preparation of nano-microcapsule preservative (2)

[0035] 1. Mix 6g of nano-SiO 2 Dissolve in 1L of distilled water, then add 20g of sodium alginate and 4g of konjac gum, put the prepared solution in a constant temperature water bath, bathe in a constant temperature water bath at 70°C for 20 minutes, stir to make it completely dissolve, after cooling, make up the remaining water, A composite wall material is prepared.

[0036] 2. Add 12g of ginger essential oil and 5g of monoglyceride to the prepared composite wall material, stir magnetically for 20min, and homogenize the emulsion under high pressure 3 times at a homogenization pressure of 35MPa. After homogenization, the nano-essential oil microcapsule preservative is obtained.

Embodiment 3

Abstract

The invention provides a nano microcapsule preservative, and a preparation method and application thereof. The preservative is prepared from fresh ginger essential oil, konjac gum, sodium alginate andnano SiO2. The preparation method is an emulsified cross-linking method; and the method takes a nano SiO2- konjac gum/sodium alginate composite film as a wall material and takes the fresh ginger essential oil as a core material, so that the nano microcapsule preservative can be prepared through cladding. The preservative is natural, healthy and safe in component, friendly in human body and environment, small in nano capsule particle size, good in heat stability, strong in slow-release capability and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of food fresh-keeping, in particular to a nano-microcapsule fresh-keeping agent and its preparation method and application. Background technique [0002] Microcapsule technology refers to embedding solid substances, liquids and even gaseous substances in tiny and sealed capsules with natural or synthetic polymer materials through a certain processing technology to form a sealed or semipermeable capsule membrane structure. . The polymer material that forms the capsule is called the wall material, and the solid substance, liquid or gas that is wrapped is called the core material. The size and shape of the microcapsules vary with each preparation condition. Usually, the particle size range of microcapsules is within 1-1000 μm, and the thickness of the wall material is generally 0.2-10 μm. Due to the characteristics of the microcapsule structure, it can change the physical properties of the core material to i...
