  • Patent number: 7494662
    Abstract: Co-product streams derived from the manufacture of vegetable oil were further processed producing materials that possess strong absorbance of visible and ultraviolet light. The compounds contributing to the light absorbance were increased and standardized to produce a fat-soluble composition with consistent and strong absorbance of ultraviolet and visible light. The fat-soluble composition is a useful photoprotective agent for various applications including protection of herbicides and pesticides. In a preferred embodiment acidulated vegetable oil is blended to a constant absorbance of light between 190 and 400 nm and used in a formula to protect a field-applied herbicide.

  • Patent number: 6822104
    Abstract: Methods for sequential saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in a polyether alcohol solvent to yield soaps with conjugated double bond systems are disclosed. The novel properties of the polyether alcohols allow the removal of water added with the alkali by boiling. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps. The reaction forms equal quantities of 9Z,11E-octadecadienoic acid and 10E,12Z-octadecadienoic acids.

  • Patent number: 6475758
    Abstract: Methods for acidification of soapstock using acids produced by fermentation with acidogenic bacteria and recovery of acidulated fatty acids are disclosed. Soapstock is advantageously acidified by fermentation of endogenous soapstock nutrients and added nutrients under controlled conditions using acidogenic bacteria. The nutrients may include carbohydrate, nitrogen, phosphorous, sulfur from defined or undefined sources. The acidification reaction avoids the use of strong acids for the treatment of soapstock, minimizes wastewater contamination with salts and produces potentially valuable by-products including lactic acid, acetic acid, glyceric acid and nutrient rich microorganisms.

  • Patent number: 6414171
    Abstract: Methods for quantitative conversion of soapstock, lecithin gums, deodorizer distillate and other by-products of vegetable oil refining containing interrupted double bond systems, to products with conjugated double bonds, using a reduced amount of alkali. Less than one mole of alkali per mole of acyl group present is required, thereby greatly reducing the need for added caustic compared with methods using oils, fatty acids and esters as starting materials. The preferred starting materials are soapstocks derived from vegetable oils rich in linoleic acid.

  • Patent number: 6409649
    Abstract: Conjugated linoleic acid is readily prepared by mixing crude alkaline glycerol solution derived as a byproduct of triglyceride transesterification and a linoleate rich triglyceride, ester, soap, phospholipid, fatty acid, or wax and heating the mixture sufficiently to conjugate the linoleate double bonds. The reaction produces a favorable isomer mixture enriched in 10,12-trans,cis octadecadienoic and 9,11-cis,trans-octadecadienoic acids.

  • Patent number: 6399802
    Abstract: Methods for acidification of soapstock and recovery of acidulated fatty acids are disclosed. Further methods of conversion of the acidulated fatty acids to esters are also disclosed. Further methods of crystallizing the acidulated fatty acids from the extraction solvent at low temperatures and fractionating the acidulated fatty acids from the extraction solvent using urea are also disclosed. The novel method of adding both a monohydric alcohol to the soapstock to lower viscosity and a strong acid to hydrolyse the soaps prevents the formation of emulsions of soaps and oils. The preferred embodiment uses a soapstock such as soybean soapstock, sulphuric acid and isopropanol. The novel process allows the quantitative recovery of fatty acids and glyceride from the soapstock by removal of the alcohol by evaporation. Alternatively the fatty acids and glyceride may be converted to esters of monohydric alcohols.

  • Patent number: 6153815
    Abstract: The invention provides DNA isolated from a plant species of the family Brassicaceae that can be introduced into the genomes of plants to produce genetically-modified plants having higher levels of squalene than the natural plants. The DNA corresponds to squalene epoxidase gene of the same or a related plant, and may have the sequence as shown by SEQ ID NO:1, SEQ ID NO:3, or SEQ ID NO:5, or a sequence having at least 60% identity with such a sequence. The DNA is introduced into the genome in a way that results in down-regulation of an exogenous plant squalene gene to suppress the expression of squalene epoxidase. The invention also relates to a process of producing genetically-modified plants, plasmids and vectors used in the method, genetically-modified plants and seeds thereof and a method of producing squalene from the modified plants.

  • Patent number: 6113908
    Abstract: Methods of treating dehulled or hull-less oat, i.e. oat groats, to produce oat pearlings, oat flour and oat bran products are described. Oat groats are abrasion milled to remove up to 15% by weight and produce pearled oat groats and pearlings. The pearlings are extracted sequentially with aqueous ethanol and hexane to produce an anti-irritant and a light oat oil, or with hexane to produce a dark oat oil and lipase. The pearled oat groats are steeped in an aqueous medium for up to 4 hours and then macerated to produce an enriched oat bran, from which an enriched beta glucan may be extracted; a refined oat flour, from which oat starch and oat protein may be extracted; and a pearled oat groat extract from which further products, such as an oat anti-irritant can be recovered.
