396 results about "Water binding" patented technology

Water binding capacity is the tendency of water to associate with hydrophilic substances whereas Water holding capacity is the ability of a matrix of molecules to entrap large amounts of water in a manner such that exudation is prevented. Bound water exists in the vicinity of solutes and other non-aqueous constituents,...

Bacterial cellulose/chitosan composite sponge dressing and preparation method thereof

The invention relates to a bacterial cellulose/ chitosan composite sponge dressing and preparation method thereof. The dressing comprises a cellulose/ chitosan composite sponge layer (1), an adhering layer (2) and a nonwoven fabric layer (3) which are placed from top to bottom in sequence. The preparation method comprises the following steps of (1) boiling a bacterial cellulose membrane with an NaOH aqueous solution, fully washing with distilled water to reach neutral state, and then drying in vacuum to obtain bacterial cellulose fibrid; (2) preparing a chitosan solution, adding the bacterial cellulose fibrid, standing and defoaming, freezing, and finally freezing and drying to obtain bacterial cellulose/ chitosan composite sponge; and (3) adhering the bacterial cellulose/ chitosan composite sponge to a polypropylene nonwoven fabric with permeable micropores through an adhesive, a hot melt adhesive or a thermosensitive adhesive, thus obtaining the bacterial cellulose/ chitosan composite sponge dressing. The dressing has the effects of stopping bleeding, diminishing inflammation, sterilizing, promoteing the wound healing, and has the advantages of no scar, high tensile strength, high water binding capacity and air and water permeability, high shape maintaining ability, etc. The preparation method is simple.

Processing method of fruit-flavor dried goose slices

The invention relates to a processing method of fruit-flavor dried goose slices. The processing method comprises the following steps of: (1) finishing; (2) freezing; (3) slicing; (4) preparing a pickling liquid; (5) vacuum tumbling; (6) tedding; (7) roasting; (8) curing by adopting a juice; (9) baking obtained slices; and (10) packaging. According to the invention, during preparation of the pickling liquid, composite phosphate and papain are added as a composite tenderness agent, the effect is obviously superior to the effect obtained after one tenderness agent is abundantly and independently used; the added Arabic gum can form a gel system with goose egg white, so that taste molecules and smell molecules in the dried goose slices can be reserved to the maximum, and the dried goose slices have good flavor; the vacuum tumbling is adopted, therefore, compared with the prior art, the processing method has the advantages that the curing time is reduced, the technological period is shortened, the pickling liquid is absorbed to the maximum, the dried goose slices are uniformly pickled, the water binding capacity and tenderness are improved, and the mouthfeel is smooth; after being cured by adopting juice, the dried goose slices are increased in content of vitamin, and improved in nutritive values, and different juices can attach different flavors.

Pholiota nameko cultivation material compatibility and method for preparing cultivation material

The invention relates to a pholiota nameko cultivation material which is characterized in that broad bean hulls are used as a main raw material, cotton linters, bran, corn flour, gypsum powder and the like are used as auxiliary materials, and the water content of the cultivation material is 65-66 percent. The invention also relates to a method for preparing the cultivation material. Compared with a saw dust cultivation material, the pholiota nameko cultivation material has the advantages that 1, the cultivation material is reasonable in matching of coarse sand fine grains, and the air permeability and water binding capacity of the cultivation material are increased, so that the growth rate of pholiota namekohypha is increased, and the bagful time is shortened; 2, the cultivation material has a reasonable carbon nitrogen ratio and balanced nutrition and promotes the growing development of sporocarp, and the yield is increased by 20-30 percent; 3, the cultivation raw-material channel is broadened, and the production cost is greatly reduced. The pholiota nameko cultivation material compatibility and the method have the social benefits that a broad bean hull substitution is used for cultivating pholiota nameko, one part of fungus-forest contradiction can be eased, waste is turned into wealth, and energy conservation and emission reduction are facilitated.
