Abstract: A method for protecting the activity and bioavailability of heat- and/or oxygen-labile compounds during processing, particularly processing by extrusion of a food product containing the heat- and/or oxygen-labile compounds. Beadlets are formed wherein the heat- and/oxygen-labile compound is protected by a shell of calcium alginate and an ancillary polymeric compound, such as gelatin. The beadlets are added to a food product prior to extrusion and protect the active compound against heat degradation during the extrusion process. The beadlets also provide a protected form of the compound that decreases oxidation. In an alternative embodiment, oxidizing agents and/or free radical initiators to be added to a product containing labile compounds are coated with the protective material to protect the labile compounds from degradation by the oxidizing agents and/or free-radical initiators.

Abstract: The present invention relates to metal carboxylates and more particularly to chromium(III) and manganese(II) salts of short chain fatty acids. A method of making the same such that there are only sub part per billion amounts of these metals in other valent forms present in the resultant salts, and the salts are suitable for use as nutritional supplementation of living organisms with the organic metal salts.

Abstract: A process for producing divalent metal carboxylates having the formula, M(CH.sub.3 (CH.sub.2).sub.x COO.sup.-).sub.2, wherein M is the divalent metal cation, zinc (Zn.sup.+2) or copper (Cu.sup.+2) and x is zero or 1 is disclosed. In this process, an anhydrous C.sub.2 -C.sub.3 carboxylic acid is admixed with a basic divalent metal compound that is an oxide, hydroxide or carbonate of Zn.sup.+2 or Cu.sup.+2 in the absence of added solvent or other diluent. The divalent metal carboxylate so produced is used as a biologically available and economical source of trace metals for supplementation in animal diets.

Abstract: A process and test kit for the rapid qualitative determination of fat oxidation based on an iodometric method for peroxide value and employing ready-made test solutions is disclosed. A visible color change is used to determine whether a fat sample contains an amount of fat peroxides in excess of a predetermined amount, and is therefore unacceptable.
