Problems solved by technology

Although these alcohol solutions can be removed by anti-solvent precipitation or spray / freeze drying in the later stage, they still do not meet the concept of "green consumption" by consumers
At the same time, the redispersibility and stability of Zein nanoparticles in aqueous systems is still a huge challenge, which limits its application as a delivery vehicle.

Embodiment 1

[0044] Embodiment 1 Preparation of ginger essential oil nanoemulsion (GEON).

[0045] Zein (≥92%) and ginger essential oil (≥90%) were purchased from Yifeixue Reagent Co., Ltd., and NaCas (≥90%) was purchased from Suo Laibao Reagent Co., Ltd. Weigh 2 g of Zein and NaCas sample powders and dissolve them in 100 mL of pure water at 25°C. Use 3M NaOH (the same below) to raise the pH of the two to 11.5, which is the lowest pH for dissolving Zein. Then both protein solutions were magnetically stirred at 600 rpm for 2 h. GEO deprotonation reference Wang et al. method with minor modifications. Add 2mL of GEO and 18mL of NaOH to the Erlenmeyer flask successively to obtain the GEO mixture, heat it at 120°C for 15min, take it out, and cool to room temperature. Next, the protein solutions of Zein and NaCas were mixed in different volume ratios to obtain mixed protein solutions with Zein / NaCas mass ratios of 0:1, 1:1, 1:2, and 2:1. After magnetically stirring at a speed of 600 rpm for...

[0068] Example 2 Preparation of ginger essential oil nanoemulsion hydrogel.

[0069] (1) Preparation of nanoemulsion hydrogel.

[0070] (1) Preparation of MFC: Weigh 40g of NaOH and dissolve it in 340mL of pure water to prepare NaOH solution. 20 g of microcrystalline cellulose (MCC) was added to the NaOH solution, placed in a water bath at 60° C., magnetically stirred at 300 rpm for 2 h, and cooled to room temperature. The sample was placed in a centrifuge and centrifuged at 8000rpm for 5min, the precipitate was retained, and it was repeatedly suction-filtered with pure water (the pore size of the filter membrane was 10 μm) until the sample showed neutrality. Then disperse the sample evenly with 1000mL pure water, and perform high-pressure homogenization on the sample under the condition of 15000PSI to obtain a milky white microfibrillated cellulose (MFC) suspension, which is placed in a 4°C refrigerator for later use.

Abstract

The invention discloses a preparation method of ginger essential oil nanoemulsion hydrogel. Firstly, ginger essential oil nanoemulsion (GEON) composed of Zein and NaCas is prepared, and then the gelation time is improved by further preparing it into nanoemulsion hydrogel. , antibacterial ability and action time, the present invention can form a hydrogel after the Schiif base reaction with the amino group on the CMCS molecular chain through the aldehyde group on the DAMFC molecular chain, and then use GEON as a solvent to prepare GEONH together with DAMFC and CMCS, The structure and performance of GEONH were adjusted with the amount of DAMFC added as a variable. After combining with GEON, the antibacterial rate of the prepared hydrogel against three bacteria increased to about 99%, and the antibacterial rate against S.aureus increased the most. , indicating that there is a synergy between GEON and CMCS. Thus, GEONH can significantly inhibit E. coli and S. aureus The growth of common spoilage bacteria in meat products, such as meat products, is expected to be applied to the antiseptic and fresh-keeping field of low-temperature meat products to extend the shelf life.

Description

technical field [0001] The invention belongs to the field of food processing materials, and in particular relates to a preparation method and application of ginger essential oil nanoemulsion hydrogel. Background technique [0002] Emulsification imparts smaller size and greater surface area to essential oils, thereby enhancing their physicochemical properties. The colloidal system of nanoemulsions can not only better protect nutrients, but also improve the stability, water solubility and bioavailability of essential oils, mask their pungent odor and reduce the impact on the sensory properties of food. In general, the emulsification properties of nanoemulsions (such as particle size, potential, embedding rate, and stability, etc.) are controlled by the type of emulsifier and emulsification technology. On the one hand, high-energy emulsification technology requires large mechanical energy and low energy utilization rate, so the cost of equipment required for production is rel...
