Use of Pyranoanthocyanins as a Stable Natural Colorant
TS-036818 — A stable natural colorant derived from fruit and vegetable pigments, with enhanced resistance to bleaching for food applications.
Anthocyanins are pigments in fruits and vegetables that have application as a natural colorant in foods. Their use in juices and beverages, currently the largest market for synthetic dyes in the food industry, is limited due to the fortification of Vitamin C which results in rapid color loss, know…

Automating the quantification of color space parameters from Visible Spectrum Absorbance
TS-036603 — Verbal communication of color is challenging, therefore mathematically-standardized color spaces are used. ColorBySpectra is software that in one click can convert large sets of absorbance data obtained from a simple spectrophotometer into color spaces: Hunter Lab, CIEL*c*h* and CIEL*a*b*. It reduces time for data collection, and sample volume and equipment needs. The software is useable on multiple platforms and would be useful in food science or other industries interested in precise color information.
There are several commonly used color spaces that quantify perceived color which include Hunter Lab, CIELab, and CIELch. To obtain these values, samples are usually presented to a colorimeter one sample at a time. Obtaining color data can be time consuming for many samples, and special equipment d…

Black Goji Anthocyanins for Natural Food Colorant
TS-034593 — Extracted anthocyanins from Black Goji fruits (Lycium ruthenicum Murr) that can be used in the food industry as a potential source of natural color in a wide pH range.
Americans spend about 90 percent of their food budget on processed foods, almost all of which contain a plethora of additives. One of the most frequently used food additives is artificial coloring, and in the past synthetic food colorants were most popular. Increasingly however, public demand has …
