    Notes: Clostridium botulinum may pose a hazard in extended shelf-life refrigerated foods. Nonproteolytic strains ofC. botulinum, which can grow at refrigeration temperatures, may be given sufficient time to grow if the shelf-life is extensive. Proteolytic strains may grow in these products if temperature abuse occurs. Mild heat treatments and vacuum or modified atmosphere packaging may select for C. botulinum and allow toxicity to occur in organoleptically acceptable products. Multiple barriers and multifactorial experiments to generate predictive models are advocated to ensure safety of extended shelf-life refrigerated foods.

    Notes: The effect of autoclaving on meat enhancement of dietary iron bioavailability was studied. Meat was mixed with FeSO4 or hemoglobin to obtain ratios of iron from meat to iron from FeSO4 or hemoglobin of 100:0, 75:25, 50:50, 25:75, and 0:100. One-half of each mixture (except meat:FeSO4 mixture 0:100) was autoclaved for 90 min at 15 psi. The meat mixtures were lyophilized and formulated into diets to provide approximately 35 mg Fe/kg. Hemoglobin regeneration efficiency (HRE) was determined as the percent iron gained as hemoglobin relative to the iron consumed. Heat increased the HREs of meat/hemoglobin mixtures and of hemoglobin. Heat did not affect the HRE of meat or meat/ferrous sulfate mixtures. Meat did not significantly enhance the bioavailability of total dietary iron.

    Temporal Changes in Serum Cholesterol Levels of Rats Fed Casein and Skim Milk Powdered Diets (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 52 (1987), S. 0 
    Details
    ISSN: 1750-3841

    Notes: The temporal cholesterolemic patterns to skim milk powder (SMP) and reprocessed SMP (RSMP) diets were compared to diets containing casein or laboratory rat chow over a 24-day period. SMP was hypocholestetemic relative to casein in rats fed a 1% dietary cholesterol. Reprocessing of SMP resulted in an apparent loss of the relative hypocholesterolemic reponse of native SMP. Amino acid analysis of SMP and RSMP, showed only marginally lower lysine levels than casein; however, the Iysine/arginine ratio was higher in SMP than either in casein or RSMP. Available lysine content in SMP was higher than in RSMP, suggesting occurrence of nonenyzmatic browning reactions. Although a similar cholesterolemic response was observed in casein and RSMP, the available lysine content of these two protein sources were markedly different, suggesting that reduced available lysine alone was not totally responsible for the lower cholesterolemic response of SMP, relative to casein.

    Notes: Proximate and micronutrient composition of cantaloupe and honeydew melons purchased from six marketing locations at marketing times near maximum and minimum product availability were determined. Cantaloupe varieties purchased at periods near maximum availability showed significantly higher (α= 0.01) levels of niacin, riboflavin, thiamin, ascorbic acid, folacin and Cr compared to those purchased near minimum availability. Honeydew melon varieties purchased at periods near maximum availability showed significantly lower (α= 0.01) levels of ascorbic acid, folacin, pantothenic acid, K, Zn, and Cr compared to those purchased near minimum availability. Although some differences were observed between values obtained and those reported in Handbook 8–9, proximate composition and mean values for micronutrients approximated those previously reported.

    DESTRUCTION OF TRICHINELLA SPIRALIS BY LOW-DOSE IRRADIATION OF INFECTED PORK (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food safety 7 (1985), S. 0

    Notes: Gamma irradiation of Trichinella spiralis-infected pork with a dose of 15 to 30 krad blocks maturation of ingested larvae in the host gut and prevents production of larval progeny. Experiments with freshly-slaughtered (prerigor) hog carcasses indicate that larvae distributed throughout the skeletal muscles have similar radiosensitivities. Neither the age of the encysted muscle larvae nor vacuum packaging of the meat significantly affected this radiosensitivity. Postirradiation holding of irradiated meat leads to little if any recovery of trichina viability. The data indicate that 30 krad cesium-137 gamma radiation can be delivered to split market-weight hog carcasses with acceptable uniformity, and that under all conditions tested such a dose can provide a substantial margin of safety for human consumption of heavily infected meat.

    Notes: Hereford yearling steers (N= 144) were alloted to one of three pasture systems: tall fescue, smooth bromegrass-red clover or orchardgrass-red clover. After the grazing period, steers were finished in drylot and then serially slaughtered at 0, 56, 84 and 112 days. Carcass quality grades and yield grade numbers increased when steers were fed grain up to 112 days. Tenderness of loin steaks increased up to 84 days, after which no improvements were observed. Sensory panel scores for grassy flavor of steaks and ground beef decreased up to 112 days. Fifty-three compounds were identified in the volatiles of melted subcutaneous fat by direct sampling-gas chromatography/mass spectro-metry. The major differences between volatiles from fat of forage-fed compared to grain-fed steers were the higher concentrations of 2,3-octanedione and various diterpenoids present in the samples of the forage-fed animals.

    Notes: The storage stability of eviscerated Indian mackerel (Rastrelliger kanagurta) irradiated at a dose of 1.5 kGy and held under melting ice was examined. Packaging in polyethylene pouches prior to irradiation gave a shelf-life of 25 days, while, nonpackaged, irradiated fish remained in acceptable condition up to 20 days. The nonpackaged irradiated fish has less irradiation odor and better appearance as compared with packaged irradiated fish during the course of ice storage. Uni-radiated and nonpackaged mackerel kept in ice were acceptable only for 14 days. The results suggest that pre-irradiation packaging was not essential for commercially adequate extension in shelf-life of the iced fish.

    Notes: The effects of electrical stimulation, kidney fat removal time, tenderloin removal time, and storage and packaging treatment on tenderness and retail display characteristics of beef tenderloin steaks were studied. Electrical stimulation increased overall desirability scores on days 2 through 4 of retail display. Steaks from sides that had kidney and pelvic fat removed prior to chilling had higher Warner-Bratzler shear force values, darker muscle color and higher retail evaluations for overall desirability on days 2 through 4 of display than did steaks from conventionally dressed sides. Tenderloin steaks that were vacuum packaged and stored 14 days had higher bacterial counts, more uniform lean color and less visual purge in the retail package than did steaks retail displayed immediately after tenderloin removal.

    Thermal Transitions in Myosin-ANS Fluorescence and Gel Rigidity (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 51 (1986), S. 0

    Notes: Thermal transitions (Tr) in myosin were monitored during constant rate heating with a thermal scanning rigidity monitor (TSRM) and a fluorescent probe, 1-anilino-naphthalene-8-sulfonate (ANS). The Tr values from fluorescent probe measurements were 37°C, 44°C, and 44°C for tilapia, rabbit, and chicken myosin-ANS, respectively. Three Tr values at 43°, 49°C, and 55°C were observed in TSRM measurements of tilapia myosin gelation, whereas a single Tr was observed in rabbit and chicken gelation at 48°C and 49°C, respecitvely. In tilapia myosin, KCl concentration and pH significantly influenced the TSRM but not the fluorescence thermograms. These results indicated that a prerequisite change occurred in the hydrophobic character of myosin just prior to the onset of gelation.

    Effect of Temperature on the Water Adsorption Isotherms of Sultana Raisins (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 51 (1986), S. 0

    Notes: The water adsorption isotherms of Sultana raisins were determined using the static method of saturated salt solutions at 20°, 25°, 30°, and 35°C. The equilibrium moisture content at water activities up to 0.70 decreased as the temperature was increased from 20° to 35°C. At higher water activities the moisture content increased sharply as the temperature was increased, resulting in crossing of the isotherm curves. This behavior is attributed to the increased solubility of fruit sugars at higher temperatures. The experimental data were fitted well with the 3-parameter GAB and Halsey equations, and best with the 5-parameter D'Arcy-Watt equation. The thermodynamic implications are discussed.
