The disclosure relates to a preparation method of eel polypeptide flavor extract, the eel polypeptide flavor extract, and the eel sauce. The preparation method of the eel polypeptide flavor extract includes the following steps: obtained by using eel processing by-products, eel cutting off the main meat tissues, successively performing microbial fermentation, Maillard reaction and extraction and separation processes. The eel polypeptide extract obtained above is used to making a condiment eel sauce. The eel sauce is nutritious and convenient, it can be used directly for table eating or served as cooking condiments to enhance the aroma and taste of dishes and increase the attractiveness of dishes. The disclosure realizes a new technological research on the preparation of polypeptide and flavor products, opens up a scientific utilization and processing method of seafood processing by-products, and provides a new way for making full use of such resources.

A color predictor is provided to predict the color of a food item given its formula comprising the ingredients and its quantities. The color predictor may utilize machine learning algorithms and a set of recipe data to train the color predictor. The color predictor can also be used by a color recommender to recommend changes in the given formula to achieve a target color.

A method for decolorization and deodorization of egg yolk oil comprises at least: adding a first ether solution to a crude egg yolk oil, and performing a first stirring process, to produce a first egg yolk oil mixture; adding activated carbon to the first egg yolk oil mixture, performing a second stirring process, and removing the activated carbon, to produce a second egg yolk oil mixture; adding a second ether solution and distilled water to the second egg yolk oil mixture, and performing a third stirring process, to produce a third egg yolk oil mixture; and removing distilled water, part of the first ether solution, and part of the second ether solution from the third egg yolk oil mixture by a distillation process, and removing the remaining first ether solution and the remaining second ether solution by a vacuum process to produce a decolorized and deodorized egg yolk oil.

According to embodiments, a dry powdered composition which may be reconstituted to provide a gelatin product includes powdered gelatin and a pelletized colorant. The pelletized colorant includes a pigment-protein complex and at least one encapsulating agent for encapsulating the pigment-protein complex. The pelletized colorant has a rate of dissolution a rate of dissolution of less than 2 grams/minute in water having an initial temperature of from about 95° C. to about 100° C. Methods of making food products with the pelletized colorant are also disclosed. In embodiments, when the food products are measured on the L*a*b* color space, the food products have an L* value of about 49 to about 57, an a* value of about −10 to about −16, and a b* value of from about −11 to about −20.5.

The present invention relates to a new high-throughput process for reducing impurities in essential oils and extracts (in particular for fragrances, fragrance ingredients, flavours and cosmetic ingredients) under mild conditions. Undesirable natural components such as waxes, but also synthetic materials such as agrochemicals and other environmental pollutants are reduced by using at least one selective nanofiltration membrane. In addition, the present invention relates to a method for reducing coloured components in essential oils to obtain a less coloured or even colourless essential oil, while achieving high re-colouration stability over time. Further, the odour quality is maintained or increased through reduction of undesirable olfactory substances to achieve a purified and higher quality oil.
