56 results about "Pro-oxidant" patented technology

Pro-oxidants are chemicals that induce oxidative stress, either by generating reactive oxygen species or by inhibiting antioxidant systems. The oxidative stress produced by these chemicals can damage cells and tissues, for example an overdose of the analgesic paracetamol (acetaminophen) can fatally damage the liver, partly through its production of reactive oxygen species.

Nutrition bar

A nutrition bar comprising about 10% wt or more of soy and / or rice protein, at least one transition metal or transition metal compound, and about 2% wt or more of a humectant, and wherein the at least one transition metal or transition metal compound is in a substantially water insoluble form at 20° C. or the nutrition bar has an Aw of 0.45 or less or about 1% wt or more of the soy and / or rice protein is in the form of nuggets and the humectant is selected from polyols. The bars have elevated levels of soy and / or rice protein, yet do not suffer unacceptable from a deterioration in taste or other organoleptic properties over time. In other aspects, a nutrition bar or other food which incorporates pro-oxidants and / or polyunsaturated fatty acids or their sources in encapsulated form, especially as microcapsules. The pro-oxidants may be metal salts such as copper, manganese, iron and / or zinc salts. Sources of omega-3 fatty acids include fish oil. Processes for preparing the polyunsaturated fatty acid capsules are also disclosed. The polyunsaturated fatty acid capsules / microcapsules are prepared by forming an emulsion of the unsaturated fatty acid with a carrier, spray drying the emulsion to form a powder and encapsulating powder, especially with a fluid bed. The invention is especially useful for encapsulating polyunsaturated fatty acids, or oil sources thereof, most preferably omega-3 and omega-6 fatty acids, such as arachidonic acid, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), lineoleic acid, linolenic acid (alpha linolenic acid), and gamma-linolenic acids, fish oil, and oil sources of C18:2 and C18:3 fatty acids such as canola oil, soybean oil or blends thereof.

Process of converting rendered triglyceride oil from marine sources into bland, stable oil

Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability. The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely. Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.
