    Notizen: The quantity of enzymes in muscle tissue is normally small and difficult to purify. Much of the comparative enzymology of food myosystems has been done with tissue homogenates or impure enzyme isolates. Conclusions relating the specific contribution of an enzyme to autolysis during the conditioning of muscle foods can be misleading. This review will focus on salient features of some enzymes which are important in postmortem metabolism of food myosystems, including enzymes involved with energy metabolism, protein catabolism, lipid catabolism and adenosine triphosphate (ATP) catabolism. Intraspecific and interspecific variation in enzymes involved with these metabolic processes will be discussed. It is beyond the scope of this treatise to provide a comprehensive coverage of each metabolic process. The main objective of this review is to discuss some of the similarities and differences of enzymes from food myosystems.

    Notizen: Ripening banana fruit contains water-insoluble pigments which have a molecular weight in excess of 4000 and a fluorescence spectrum identical to lipofuscin or age pigments. The pigments were not decomposed by irradiation with ultraviolet light. The flourescent substances increased linearly in the peel and quadratically in the pulp during the course of ripening. It is suggested that the fluorescent substances are products of membrane lipo-protein peroxidation like the lipofuscin pigments identified in animal tissues.

    Notizen: Microwave and bake cooking operations destroyed approximately 90% of the ipomeamarone in sweet potato roots. 4-ipomeanol was more heat stable than ipomeamarone, although it also decreased substantially as a result of normal cooking. These findings are contrary to a previous report which indicated that these toxins were not destroyed by cooking.

    Notizen: Green banana fruit manifested severe chilling injury after 5–7 days storage at 5°C and 80% relative humidity. (Severe chilling injury is described here as a failure of the fruit to ripen on removal to conditions conducive to normal ripening.) The recoverable “wall bound” peroxidase fraction exhibited a sharp decline during this initial period of stress. Subsequent storage of severely chilled fruit at. 5°C resulted in a gradual increase in the “soluble” peroxidase pool and a rise in “wall bound” peroxidase to levels comparable to normal green fruit. After 30 days storage of fruit at 5°C the “soluble” and “wall bound” fractions of peroxidase peaked and declined rapidly in the latter pool. The increase in peroxidase of cold stressed fruit involved qualitative changes in isozyme species that differed from those isozymes which emerge during normal fruit ripening. It is suggested that the initial decrease in “wall bound” peroxidase results in a loss in capability of the tissue to adapt to low temperature stress. The belated increase in peroxidase activity may be associated with a typical “cold hardening” response which develops only after an irreversible or “plastic strain” damage has occurred

    Notizen: SUMMARY Changes during CA (controlled-atmosphere) storage of excised shoots of asparagus (Asparagus officinalis L) were studied. Storage in 5% CO2, at 35°F and 95% relative humidity resulted in increased pH, decreased total acidity and total solids, and an increase in soluble solids. There was also more retention of chlorophylls in the CA-stored asparagus. These effects became more pronounced as the concentration of CO2 in the atmosphere was increased. The degradation products of chlorophylls in the CA-stored samples were exclusively the pheophytins. Correlations between changes in pH and the degradation of chlorophylls were made.

    Notizen: A crude preparation of gastric proteases from Harp Seal (Pagophilus groenlandicus) was found to coagulate milk over a wider pH range than porcine pepsin and had a higher ratio of milk clotting to proteolytic activity with hemoglobin at pH 1.8. Cheddar cheese prepared with seal gastric protease (SGP) gave significantly higher sensory scores than cheese made with calf rennet. Chemical analysis of the cheeses revealed a lower concentration of citrate-HCl soluble nitrogen and less free and peptide-bound amino acids in SGP cheese than in the cheeses made with calf rennet and Mucor miehei protease.
