Publication number: 20130064944Abstract: The invention provides a stable concentrated dairy liquid, such as concentrated milk, with improved flavor, color, and mouthfeel, and a method of production thereof. The method utilizes specific thermal treatments to produce the stable concentrated dairy liquid to which a stabilizer and mouthfeel enhancer are added. The resulting products have a sterilization value Fo of at least 5 that is also resistant to gelling and browning during high temperature sterilization and is also resistant to gelling and browning during storage for greater than six months. The method balances such thermal treatments with addition of stabilizer and enhancer to achieve the desired flavor/mouthfeel and sterilization and to achieve reduced level of soluble protein in the concentrated milk prior to concentration to resist gelation and minimize browning. Moreover, such processing may be utilized in a milk that is concentrated to a factor of 2.7 fold or higher and contains at least 8.5 percent protein.Type: ApplicationFiled: August 2, 2012Publication date: March 14, 2013Inventors: Kenneth W.

Publication number: 20080311276Abstract: The present invention relates to a process for producing glucosinolates, particularly glucoraphanin, from cruciferous plants. More particularly, a method is provided for producing glucosinolates from agricultural by-products and waste. The general method comprises providing a mixture of glucosinolate-containing plant material and liquid, heating the mixture to inactivate enzymes in the plant material, contacting the heat inactivated mixture with an anion exchange membrane whereby at least a portion of the glucosinolates are extracted from the liquid and absorbed onto the anion exchange membrane, and releasing the glucosinolates from the anion exchange membrane. Preferably, the extraction and release steps are repeated at least once. The glucosinolates produce by the method of the invention may be incorporated into a variety of food products, pharmaceuticals, and health supplements.Type: ApplicationFiled: June 12, 2007Publication date: December 18, 2008Applicant: KRAFT FOODS HOLDINGS, INC.Inventors: Leslie George West, Theresa Pomerleau, Nathan V.
