  • Publication number: 20120070541
    Abstract: Natural maple saps and maple syrups are contacted with an immobilized isomaltulose-forming microorganism to convert at least 20% of the sucrose contained in the sap or syrup to isomaltulose. The microorganism may be immobilized on calcium alginate and prepared as a column through which sap or syrup flows. The resultant isomaltulose-containing solutions are concentrated to produce reduced or low glycemic index sugar syrups, semi-solid and solid sugar products.

  • Patent number: 7022363
    Abstract: A continuous process for separating components of flaxseed is described. Flaxseed is dried to a moisture content of from about 0.5% to about 3.0%, after which is introduced into a separation chamber having an abrasive rotator therein. As the flaxseed passes over the abrasive rotator, contact with rotator separates the flaxseed components into hulls and kernels. Hulls and kernels are separated and may be used in this form or processed further. Hulls may be further processed by extraction with water and with hexane to remove flaxseed gum and oil, respectively. These two extractions may be done in any order. The process results in a lignan-rich component of flaxseed, a gum extract and oil. These separate components of flaxseed may be used in products such as feed, personal care products or nutraceuticals.

  • Publication number: 20030131737
    Abstract: A continuous process for separating components of flaxseed is described. Flaxseed is dried to a moisture content of about 1% or less, after which is introduced into a separation chamber having an abrasive rotator therein. As the flaxseed passes over the abrasive rotator, contact with rotator separates the flaxseed components into hulls and kernels Hulls and kernels are separated and may be used in this form or processed farther. Hulls may be further processed by extraction with water and with hexane to remove flaxseed gum and oil, respectively. These two extractions may be done ill any order. The process results in a lignan-rich component of flaxseed, a gum extract and oil. These separate components of flaxseed may be used in products such as foods, personal care products or nutraceuticals.

  • Patent number: 6194016
    Abstract: The present invention provides for optimal extraction conditions for extracting yellow mustard gum from yellow mustard bran to provide for high yield. The four variables examined were extraction temperature, pH, water:solid ratio and extraction time. Of these variables, temperature and pH had a much greater influence on the yield and rheological properties of the extracted gum compared to water/solid ratio and extraction time. Optimum extraction conditions were temperatures between 50-70° C., pH 7-10, water/solid ratio of 40:1-60:1 and extraction time of 2-2.5 hr. The yield of gum obtained under the optimum extraction conditions was 30% of bran weight. The extracted gum exhibited maximum shear thinning flow behaviours. It can be incorporated into cosmetic products and skin lotions.

  • Patent number: 5976560
    Abstract: The present invention is a replacement for petroleum jelly as a base for products suitable for application to the skin. It is comprised of vegetable oil and silica. The vegetable oil is preferably a canola oil and more preferably a high oleic acid/low linolenic acid canola oil. The silica is preferably untreated fumed silica powder. The vegetable oil is preferably present in the range of 50-90% and most preferably 80%. The silica is present in the range of 5-15% and most preferably 10%. Other ingredients which may be added include vitamin E, margarine or butter, starch, and sunscreen. The base of the present invention has a significantly higher melting temperature than petroleum jelly.
