Spiced egg manufacturing method

The invention provides a spiced egg manufacturing method. The spiced egg manufacturing method comprises the following steps of 1, carrying out egg cleaning, illumination, drying, sorting and sterilization, 2, steaming the egg, 3, removing the shell of the egg, 4, flushing the egg without shell by clear drinking water and drying the water on the surface of the egg without shell at a temperature of 50-60 DEG C for 20-40min, 5, carrying out pickling by adding a proper amount of clear water into anise, cassia bark, common fennel fruit, myrcia and table salt to obtain a pickling material, boiling the pickling material, cooling the pickling material to a temperature of 4-10DEG C, putting the egg without shell into the pickling material, and carrying out pickling for 8-12h so that the egg has a pickling material taste, 6, carrying out boiling coloring: preparing a coloring material from water, dry capsicum, Chinese prickly ash, myrcia, white sugar and soy sauce and putting the pickled egg into the coloring material for uniform coloring, 7, carrying out vacuum sealing packaging, and 8, carrying out high-temperature disinfection. Through drying and low-temperature pickling, the egg has a complete pickling material taste and energy is saved. The pickling process and the boiling coloring process are carried out respectively so that a pure taste of the spiced egg is guaranteed. The spiced egg has a quality guarantee period prolonged by at least 1-2 months.

Composite clarifying agent for ginger juice and preparation method of extracting solution of clarified ginger juice

The invention relates to a composite clarifying agent for ginger juice and a preparation method of an extracting solution of clarified ginger juice, and belongs to the technical field of food processing. The composite clarifying agent for the ginger juice is characterized in that attapulgite is used for supporting chitosan and matched with sodium alginate, sodium carboxymethyl cellulose, xanthan gum, collagen and tea polyphenol, the composite clarifying agent has excellent flocculation effect as well as good biocompatibility, adaptability and safety, can adsorb suspended solids, pigments and the other substances in the ginger juice more comprehensively and thoroughly, has antiseptic and bacteriostatic functions and can prolong the storage period of the ginger juice effectively. According to the preparation method of the extracting solution of the clarified ginger juice, the content of gingerol in extracted ginger juice is increased greatly while nutrients of raw materials are retained sufficiently, nutrient loss is small, the use amount of the clarifying agent is small, the stability of the ginger juice is improved remarkably, the prepared ginger juice is clear and transparent in appearance and glittering and translucent in color, the pungency of the ginger juice is reduced, the taste is mellow, and the sensory quality is improved obviously.

Making method of preserved black jerusalem artichoke

The invention discloses a making method of preserved black jerusalem artichoke, and belongs to the technical field of food processing. The problems that in the existing preserved jerusalem artichoke production technology, preserved jerusalem artichoke is not suitable for glycosuria patients due to the fact that saccharose is exogenously added, and food safety is potentially affected due to the fact that sodium hydrogen sulfite and other food additives are added are solved. The processing technological process comprises the following steps of raw material freezing, sorting and cleaning, processing through zymogen, sealing, fermentation, drying, packaging, finished product forming and cold storage. Compared with raw jerusalem artichoke, in the preserved black jerusalem artichoke, the certain synanthrin content is reserved, the content of reducing sugar and polyphenols is obviously increased, a large number of melanoidins are produced, the product reserves the functions of regulating blood sugar in two ways, lowering blood fat, proliferating bifidobacteria, promoting mineral substance absorption, preventing and treating constipation, improving intestinal tract microenvironment, enhancing immunity, resisting cancer and preventing obesity of the synanthrin in the raw jerusalem artichoke to the certain degree, and the preserved black jerusalem artichoke has the stronger antioxidant function due to the fact that the content of the polyphenols and melanoidins is obviously increased.

Method for extracting natural red pigment from pitaya and application thereof

The invention belongs to the technical field of extraction and discloses a method for extracting a natural red pigment from pitaya and application thereof. The method comprises the following steps: (1) selecting fresh red pitaya, peeling off, dicing and crushing flesh to obtain fruit pulp, and then refrigerating the fruit pulp; (2) taking out the refrigerated fruit pulp in the step (1) and unfreezing at the room temperature, then adding distilled water and pectinase and uniformly stirring, and extracting at 20-35 DEG C for 0.5h-2h; (3) filtering an extracting solution extracted in the step (2), and centrifuging the obtained filtrate to obtain a clarified pigment solution; and (4) mixing the clarified pigment solution obtained by the step (3) with wall materials, stirring at the room temperature for completely and uniformly mixing, and drying to obtain a dry pigment product. The method has the advantages of simplicity in operation, high efficiency and energy saving, environmental friendliness and capability of keeping natural active components in the pitaya to the greatest extent; the weight of freeze-dried products is light and the quality is good; the products can be stored for a long time and are convenient to transport; and the obtained pigment solution can be directly applied to food production.

Microencapsulation method capable of increasing stability of anthocyanin, product prepared by microencapsulation method and use of product

The invention discloses a microencapsulation method capable of increasing stability of anthocyanin, a product prepared by the microencapsulation method and use of the product. The microencapsulation method comprises the following steps of S1, using sodium alginate as a wall material, adding the sodium alginate and calcium carbonate to water, and performing swelling for 1-2h so as to obtain a wallmaterial gel system; S2, using anthocyanin obtained through a special preparation technology as a core material, sufficiently and uniformly mixing the wall material gel system with a anthocyanin solution for standby application so as to obtain a water phase; S3, mixing Span80 with vegetable oil so as to obtain an oil phase, mixing the water phase with the oil phase, performing magnetic stirring, and performing emulsifying so as to obtain W / O emulsion; and S4, adjusting the pH of the W / O emulsion to acid, mixing the W / O emulsion with a table salt buffer solution, performing standing for 1-2h, and separating the oil phase from the water phase so as to obtain liquid anthocyanin microcapsules. The anthocyanin is prepared through a special preparation technology, so that yield and purity are increased; and besides, the microencapsulation method and the drying condition of the anthocyanin are optimized through improved technological parameters, so that the structural stability of the anthocyanin is guaranteed, and the cost is reduced.
