  • Influence of free fatty acids on sweet cream butter flavor

    Creator:
    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...

  • Volatile compounds from thermally oxidized methyl oleate

    Creator:
    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...

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

    Creator:
    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...

  • Inhibition of Pseudomonas species by hydrogen peroxide producing Lactobacilli

    Creator:
    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...

  • Heat-induced compounds in strawberries

    Creator:
    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...
