| 20120034658 | Methods for Creating Color Variation in Anthocyanins Produced by Cell Culture - Disclosed are methods for obtaining blue anthocyanin pigments and compositions including such pigments. This blue anthocyanin is present at an acidic pH (where anthocyanins are most stable) and may be used as a natural color additive. The methods can include cultivating a plant callus from a plant capable of producing anthocyanin in which the callus is treated with a blue anthocyanin-generating agent at a concentration sufficient to generate callus with blue anthocyanin pigments. The method can also include recovering the blue anthocyanin pigments from the culture. In an example, the blue anthocyanin-generating agent is ammonium molybdate. | 02-09-2012 |
| 20120021080 | Production and Extraction of Procyanidins from Plant Cell Cultures - Provided herein are methods of making cocoa polyphenol preparations, which methods comprises harvesting cocoa polyphenols, for example, procyanidins, from the cell suspension culture. In examples of these methods, the resultant cocoa polyphenol preparation is substantially (or in some cases, completely) free of detectable caffeine and theobromine, and more generally substantially free of xanthine alkaloids. Methods of producing a cell suspension culture of cacao cells are also described, including cell suspension cultures useful for making cocoa polyphenol and, more specifically, procyanidin preparations. | 01-26-2012 |
| 20110251408 | PLANT CELL CULTURE FOR PRODUCTION OF NATURAL PRODUCTS WITH REDUCED GLUCOSINOLATE CONTAMINATION - Disclosed are methods for obtaining a natural product preparation with reduced glucosinolate contamination from a plant of Brassicaceae. The methods can include cultivating a plant callus from a plant capable of producing a desired natural product, selecting a callus with reduced glucosinolate production, and cultivating the selected callus in a liquid medium. The method can also include recovering the natural product from the culture. Also disclosed are methods for obtaining cabbage anthocyanin with reduced glucosinolate contamination. The methods can include cultivating a red cabbage plant callus with reduced glucosinolate production in a liquid medium to obtain a suspension culture and cultivating the suspension culture in a medium lacking a nitrogen source. The method can also include recovering the anthocyanin with reduced glucosinolate contamination from the culture. Finally, several specific low-glucosinolate cell lines are described. | 10-13-2011 |
