    FOOD IRRADIATION: BENEFITS AND CONCERNS (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food quality 13 (1990), S. 0 
    Details
    ISSN: 1745-4557

    Notes: The benefits and concerns about treating foods with ionizing radiation are reviewed. Radioactivity cannot be induced in foods by treatment with gamma rays from 137Cs or 60Co, X-ray sources of 5 MeV or lower energy, or electrons of 10 MeV or lower energy. The evidence supports the safety and efficacy of using ionizing radiation for insect disinfestation of grains; dried spices, vegetables and fruits; and fresh fruit. Species and dose dependent phytotoxic and vitamin changes may occur in some fruits at greater doses than currently approved by the U.S. Food and Drug Administration. Irradiation can inactivate protozoan or helminth parasites and significantly decrease the probability of viable food-borne bacterial pathogens in fish, poultry, and red meats. The titers of amino acids, fatty acids, and vitamins of chicken meat sterilized by thermal, electron-beam, or gamma radiation are presented. On the whole, the data support the safety and efficacy of the process.

    Gamma Irradiation Effects on Thiamin and Riboflavin in Beef, Lamb, Pork, and Turkey (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 60 (1995), S. 0

    Notes: A study was made of the loss of thiamin and riboflavin due to gamma irradiation of beef, lamb and pork longissimus dorsi, turkey breast and leg muscles. Thiamin losses averaged 11%/kiloGray (kGy) and riboflavin losses 2.5%kGy above three kGy. The rate of loss of thiamin in beef was higher than that in lamb, pork and turkey leg, but not turkey breast. with losses of 16%/kGy in beef and 8%/kGy in lamb. The rate of thiamin loss was not related to sulfhydryl, protein, moisture, fat or water content, pH or reducing capacity by redox titration. Loss of riboflavin was not different among species. Any detriment from such slight losses would seem to be more than compensated by the advantage of controlling bacteriological contamination by irradiation processing.

    Notes: Vacuum-packaged ground fresh pork samples absorbed gamma radiation doses of 0. 0.57. 1.91. 3.76. 5.52. or 7.25 kGv at 2°C. Samolcs were analyzed after 1, 7, 14, 21, 28,‘or 35 days itorage at 2°C’for presence and number of aerobic and anaerobic mesophiles and endospore formers, and aerobic psychrotrophs. Conventional plate counts did not detect surviving microflora in any sample that received an absorbed dose of 1.91 kGy or higher, even after refrigerated storage for up to 35 days. The microflora in the control were predominantly Gram-positive for the first 21 days; however, Serratia predominated at 28 and 35 days. Staphylococcus, Micrococcus, and yeast species predominated in samples that received 0.57 kGy.

    EVALUATION OF THE PROTEIN QUALITY OF SINGLE-CELL PROTEIN PRODUCED FROM MESQUITE (1977)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Cells of Pseudomonas JM127 were grown in a medium containing mesquite wood as the sole source of carbon. The nutritional value of the microbial protein thus produced was determined. The protein contained more lysine and methionine than the FAO/WHO amino acid pattern and the requirement of infant, child or adult. The net protein utilization measurements indicated that the biological value of protein in the intact single cells was inferior to that of casein. The net protein utilization and nitrogen digestability were significantly improved when the cells were mechanically homogenized.

    Comparison of batch and semicontinuous cultures for production of protein from mesquite wood by Brevibacterium sp. JM98A (1975)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 17 (1975), S. 1749-1760 
    Details
    ISSN: 0006-3592

    Notes: The production of protein by a Brevibacterium sp. JM98A usingmesquite wood as the substrate was compared in batch and semicontinuous cultures. A 14 liter glass fermentor with automatic pH, temperature, and foam control was used for the study. A pH range of 6.6 to 7.2 was optimum for the growth of JM98A. The batch and semicontinuous cultures were compared on the basis of viable cell counts, protein production, CMC-Ase (β-1,4-glucanase) activity, and filter paper cellulase (β-1,4-glucan cellobiohydrolyase) activity. Total hexose, cellulose, and reducing sugar consumption were measured. The semicontinuous process yielded 2.97 times as much protein in 72 hr as the batch cultures. Most of the biomass resulted from the utilization of soluble sugars rather than from the degradation of cellulose during the semicontinuous process.

    Notes: Brevibacterium JM98A (ATCC 29895) was grown aerobically in carbon-limited continuous culture on the following substrates: gluconic acid, galactose, fumaric acid, glutamic acid, and aspapagine. Both whole and trichloacetic acid(TCA)-ex-tracted cells were analyzed for their amino acid compositions. No significant variations of amino acid profile were induced by change of substrate. Only the valine content varied significantly with growth rate. Some significant variations were observed between whole and extracted cell samples, primarily in the levels of the essential amino acids threonine, cystine, and valine.
