Roles of microorganisms in the deterioriation of rockfish

Schöpfer:: Lobben, J. C. and Lee, J. S.
Abstract:: Seven species of microorganisms indigenous to fish were inoculated into sterile fish muscle, obtained from Sebastodes alutus and Sebastalobus alascanus, and the production of total volatile acids (TVA) and total volatile bases (TVB) was determined during storage at 1 C. No production of TVA and TVB was noted in sterile...

Gas chromatographic identification of chlorinated insecticides based on their U.V. degradation

Schöpfer:: Banks, K. A. and Bills, D. D.
Abstract:: Certain chlorinated insecticides can be identified by electron capture gas-liquid chromatographic (EC-GLC) analysis of the prepared sample before and after treatment with ultraviolet irradiation, Upon U.V. treatment, characteristic degradation products arise from the insecticides investigated. Comparison of the degradation pattern obtained by EC-GLC of unknown and authentic insecticides provides an...

Volatile compounds from thermally oxidized methyl oleate

Schöpfer:: Withycombe, Donald A., Libbey, L. M., and Lindsay, R. C.
Abstract:: Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...

Heat-induced compounds in strawberries

Schöpfer:: Sloan, Jerry L.
Abstract:: Dimethyl sulfide, acetaldehyde, isobutyraldehyde, furan, 2-furaldehyde, 2-acetyl furan, and ethyl furoate were produced when pureed strawberries were heated to 120° C. for 30 minutes. Shorter heating periods were sufficient to produce the first three compounds. With the exception of acetaldehyde, none of the heat-induced compounds were detected in unheated, pureed...

Lipid-protein interactions : autoxidation studies involving freeze-dried methyl linolenate-gelatin foams

Schöpfer:: Wehr, H. Michael and Sinnhuber, Russell O.
Abstract:: Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...

The effect of irradiation with ultraviolet light on chlorinated hydrocarbon insecticides : a review

Schöpfer:: Banks, Kenneth A.
Abstract:: Pesticide chemists have recognized since the 1940's that ultraviolet light was deleterious to the insecticidal properties of certain compounds. However, it has been only within the last 15 years that a number of photodecomposition products of the chlorinated hydrocarbon insecticides have been isolated and identified. The degradation of insecticides by...

Influence of free fatty acids on sweet cream butter flavor

Schöpfer:: McDaniel, Mina R., Sather, Lois A., and Lindsay, R. C.
Abstract:: A threshold pattern for the even-numbered free fatty acids (FFA) in butter depended on chain-length. Butyric acid had the lowest total average flavor threshold (AFT) of the more volatile FFA, and the total AFT values increased as chain-length increased through hexanoic and octanoic acids. A soapy after-taste predominated at and...

Inhibition of Pseudomonas species by hydrogen peroxide producing Lactobacilli

Schöpfer:: Price, Robert James and Lee, J. S.
Abstract:: Eighty-one microbial species isolated from seafoods and other marine sources were examined to determine the extent of interactions among these species. Spot-plates, cross-plates, and concurrent growth experiments at 7, 15, 20, and 30 C indicated that Lactobacillus species were capable of inhibiting other microorganisms. Lactobacillus species isolated from oysters and...

The application of dynamic programming to the description and optimal control of dynamic processes

Schöpfer:: Moser, David Roy
Abstract:: The demand for improved controllers creates the need for synthesis techniques which emphasize optimality. Optimality automatically infers stability. This thesis presents one such technique which is not limited to linear systems. The theory of dynamic programming is applied to the synthesis of optimal controllers with emphasis on missile flight control...
