4 results about "Artificial colors" patented technology

This invention relates to the field of food processing technology and discloses a completely additive-free, non-fried convenience food and a multi-stage preservation process. The convenience food includes a non-fried noodle cake and a seasoning packet. The noodle cake is made solely from wheat flour and drinking water, without any added food additives. The seasoning packet includes chili oil and soup base packets, etc. The entire system is free of chemical preservatives, synthetic flavorings, artificial colors, and chemical flavor enhancers. This invention constructs a plant-based synergistic preservation system through a compound of natural spices, combined with a multi-stage preservation process of "gradient humidity-controlled drying, segmented temperature-controlled sterilization, aseptic filling, inert gas replacement, and high-barrier packaging." This solves the industry pain points of additive-free convenience foods, such as difficulty in maintaining shelf life at room temperature, easy oxidation and deterioration, and weak flavor. It achieves a room-temperature sealed shelf life of ≥10 months, while ensuring good rehydration of the noodle cake and a chewy texture, and a harmonious and rich flavor in the seasoning packet. It is suitable for large-scale industrial production and meets the needs of healthy consumers.

The application discloses a double-dosage beverage of a medicinal and edible improved formula of Taohong Siwu Yin based on an ancient recipe and a preparation method thereof, and belongs to the technical field of food and beverage. The application improves the formula of traditional Taohong Siwu Yin by using medicinal and edible raw materials, and prepares two kinds of beverages of plant protein type and clear juice type, without adding sucrose, sugar substitutes, chemical preservatives, artificial flavors and artificial colors in the whole process. The preparation adopts a low-temperature secondary extraction process at 88-90 DEG C, superfine pulping, two-stage homogenization, precision filtration, vacuum degassing and ultra-high temperature instantaneous sterilization process, the plant protein type forms a stable emulsion system through homogenization, the clear juice type guarantees the clarity through precision filtration and degassing, and the double-dosage type can be preserved for 6 months at room temperature without preservatives. The application solves the problems of similar beverages, such as bitter taste, poor stability and single dosage form, and the process is standardized and suitable for industrial production.

The invention relates to the technical field of food processing, and particularly discloses functional colored potato meal replacement powder and a preparation method thereof.The functional colored potato meal replacement powder is prepared from, by mass, 30%-40% of colored potato powder, 15%-25% of prebiotics, 20%-30% of a protein composition, 3%-8% of natural flavor substances, 1%-5% of a natural sweetening agent and 1%-2% of sodium carboxymethyl cellulose. Fresh colored potatoes are used as raw materials, the colored potato cooked powder is prepared through multiple procedures, and antioxidant polyphenol substances in the colored potatoes are greatly reserved in the preparation process; on the basis, the layering phenomenon after the colored potato powder is brewed is solved by improving the brewing property of the powder; and natural substances are added to adjust the taste and nutrition, and no artificially synthesized pigment or additive is added, so that the colored potato meal replacement powder which is easy to brew, balanced in nutrition, strong in satiety and suitable for various people to eat is obtained, and the variety of colored potato foods is enriched.

The invention discloses a precious wood imitating dyeing-reinforcing composite modifier as well as a preparation method and application thereof, and belongs to the technical field of polymer modifiers. A natural dye, melamine, glyoxal, modified silica sol and a light-resistant assistant are used as raw materials, a dye formula is blended by using a computer intelligent algorithm, so that a precious wood imitating dyeing-reinforcing composite modifier is prepared, the material is immersed in the precious wood imitating dyeing-reinforcing composite modifier, vacuum impregnation is performed, and the precious wood imitating dyeing-reinforcing composite modifier is obtained. And the imitated precious wood can be obtained. According to the precious wood imitating dyeing-reinforcing composite modifier, the mechanical property and the ultraviolet aging resistance of materials are effectively improved, the dyed materials are basically consistent with precious wood in color, and the problems that manual color matching efficiency is low, the mechanical property of the materials is poor, and the additional value is low are solved.
