  • Patent number: 8470858
    Abstract: The present invention comprises an agave syrup stored for at least eight weeks, having phytochemicals preferably selected from the group comprising flavonoids, polycosanols and sapogenins, which provide anticancerigen and antioxidant properties to the agave syrup. It is also described an extract of said agave syrup and a related method for its extraction and application for inhibiting the growth of cancer cells.

  • Publication number: 20060228455
    Abstract: The present invention relates to a procedure for mixing dehydated nopal flour and/or other vegetable flours with cereal flours, refined and/or whole flours from corn, wheat, oats and other leguminous and/or oleaginous flours and obtaining peculiar foodstuffs due to color and nutritional profile high in fiber and other nutrients. Humankind's diet is generally low in dietary fiber, vegetables in general and nopal in particular, are one of the richest natural sources of dietary fiber, nopal's virtue is its very high content of insoluble fiber and soluble fiber. Similarly, using this current procedure it is possible to substitute water by liquefied nopal and/or other liquefied vegetables in the elaboration of products like tortillas, bread, cookies, pastas, wheat flour tortillas, etc., that may or may not be a step in the previous procedure.

  • Publication number: 20060024394
    Abstract: A group of phytochemical compounds extracted from whole germinated or not germinated black beans (Phaseolus vulgaris L) and/or their dry milled fractions such as seed coats or hulls and cotyledons is described. These phytochemicals are classified as phenolics, such as polyphenols, flavonoids, coumarins, and tannins, triterpenes such as saponins, phytosterols and other antioxidant compounds that proved to be effective to decrease cancer proliferation of hormone dependent mammary (MCF-7), hormone independent hepatic (HepG2) and colon (Caco2) cancer cells. They also effectively protect against chemical damage induced with DMBA and furthermore prevented cancer induced by this chemical in Wistar rats and also reduced tumor size when consumed after tumor detection. Methanol, acetone, ethanol, water and mixtures of these solvents were used to obtain the extracts from raw, cooked, and germinated black beans of different varieties, both from the whole grain and the hulls.

  • Publication number: 20050084939
    Abstract: This invention is directed to a novel process in which raw sugarcane juice is first refined through a number of steps and then bioenzymatically converted into refined invert syrup or glucose-fructose concentrated solution using a reactor packed with immobilized invertase. The refining steps preferably include a first filtration (particle filtration or microfiltration) followed by a second filtration (microfiltration or ultrafiltration) and then at least one pass through a column packed with an anionic exchange resin. The refined sugarcane juice can be optionally concentrated and/or pasteurized before passing through a reactor packed with immobilized invertase to convert sucrose to glucose - fructose.
