Problems solved by technology

[0003] The study found that the fiber content of the pomelo peel sponge layer (4.59% pectin, 19.54% protopectin, 13.94% cellulose, 9.73% hemicellulose, and 3.26% lignin) was very high. The study of chemical and resource utilization can realize the effective utilization of the pomelo peel sponge layer while solving the problems of the grapefruit processing industry. At present, the research on nanofibers is mainly in its preparation and structural characterization, and the use of pomelo peel sponge layer has not been found yet Preparation of Pickering Emulsions Using Nanofibers

Abstract

The invention belongs to the technical field of food processing, and discloses a shaddock peel sponge layer nanofiber stabilizer and a preparation method and application thereof. The preparation method of the shaddock peel sponge layer nanofiber stabilizer is disclosed for the first time, raw materials used in the preparation method are from shaddock processing by-products, the cost of the raw materials is extremely low, no pollution is caused to the environment, the preparation process is simple and easy to implement, high-valued and resource utilization of the shaddock processing by-products is improved, and the economic benefits of relevant shaddock processing enterprises are increased; the shaddock peel sponge layer nanofiber stabilizer prepared by the method can be used for preparing Pickering emulsion, and has better emulsification effect and emulsification stability. Compared with a traditional surfactant stable emulsion, the Pickering emulsion provided by the invention has more advantages and higher safety and biocompatibility, and meanwhile, the sponge layer nanofiber can also be used as a dietary fiber supplement in the emulsion.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a pomelo peel sponge layer nanofiber emulsion stabilizer and a preparation method and application thereof. Background technique [0002] Traditional emulsions are stabilized by synthetic surfactants, which not only cannot provide long-term stability for emulsions, but also endanger human health and even threaten environmental safety. Pickering emulsions use solid particles instead of surfactants to stabilize emulsions and have ultra-high performance. stability. Among the many Pickering stabilizers, nanofiber stabilizers are the most promising class of excellent materials for forming and stabilizing food-grade Pickering emulsions with high aspect ratios, good biodegradability and biocompatibility. Series features. In addition, they not only provide good stabilization for emulsions, but also act as dietary fibers to lower cholesterol and improv...
