    Notes: A mathematical model of microwave thawing of homogeneous food products is developed and solved numerically using the Modified Isotherm Migration Method. The model is used to predict thawing time and temperature profiles for microwave thawed meat cylinders at three frequencies (2450 MHz, 915 MHz, 300 MHz) and different power levels. Model and experimental results for thawing a lean beef cylinder heated at low microwave power using 2450 MHz frequency compare well. The advantage of using 915 or 300 MHz power over 2450 MHz power is shown by calculations. The results show that microwaves significantly accelerate the thawing rate. The mathematical model is explored as a tool for designing optimal microwave/convective heating protocols for rapidly thawing foods in desired temperature ranges.

    Notes: The effects of field application rates, number of applications, interval to harvest after field treatment with ethylenebisdithiocarbamate (EBDC) fungicide and the effect of washing on the levels of the residue ethylenethiourea (ETU) in canned spinach were studied. High rates of applied EBDC high number of field applications and applications closer to harvest time resulted in canned spinach with high levels of ETU. Washing with water before processing significantly reduced the levels of ETU in spinach from all the field treatments, but washing with a solution of sodium hypochlorite and a mild detergent reduced even further the levels of ETU.

    Notes: Xanthomonas campestris pv. cajani is reported for the first time from Fiji as the cause of potentially serious pustular stem lesions of pigeonpea. Cultivars and breeding lines differed in susceptibility. The cause of another stem canker disease, characterized by smooth lesions, remains undetermined.

    Notes: Twenty-two cultivars of Phaseolus vulgaris, mentioned in the literature as differential cultivars or sources of resistance, were screened with isolates representing 10 races of Colletotrichum lindemuthianum, to test their suitability as differentials. Single-plant selections from eight cultivars were chosen, with genetic uniformity for resistance and with clear positive or negative reactions following inoculation with all 10 individual races. These differentials are proposed as a standard set for international use, to make the identification of C. lindemuthianum races internationally more comparable. The criteria for a set of differentials, and the influence of cultivar, fungus race and environment on the host-pathogen reaction are discussed.

    Notes: A model system of six organic acids and water was prepared using two pH ranges and two nitrate levels and packed in soldered sideseam tinplate and welded sideseam enameled cans. Can vacuum, Fe and Pb content were determined after 8-months storage at room temperature and at 38°C. The ECCS plate cans had lower can vacuums and lower solution Fe content than the tinplate cans. Polygalacturonic acid (PGA) was an aggressive corrosive agent in both can types. Water, PGA and malic acid solutions contained the highest concentrations of Pb.

    Notes: Eight isoenergetic and isonitrogenous diets containing graded levels of inorganic phosphorus were fed to juvenile red drum Sciaenops ocellatus for an 11 week period. Red drum were maintained in a brackish water (5–6 ppt) recirculating system. There were no significant differences in weight gain or feed conversion. However, survival was generally lower for fish fed deficient diets. Phosphorus supplements up to 0.86% increased bone calcium and scale ash, calcium, and phosphorus values. Bone ash and phosphorus were not significantly affected above 0.71% dietary phosphorus. It appears that approximately 0.86% dietary phosphorus is needed for maximum tissue mineralization of juvenile red drum.

    Notes: Each year, thousands of tons of citrus concentrate are stored and transported throughout the world at 62° Brix. Increasing this concentration to 72° Brix can result in substantial savings. Fresh orange juice, treated mechanically or with pectic enzymes to reduce its viscosity, was concentrated to 72° Brix in a commercial processing plant, then samples were stored in barrels in a tank farm at −7 or at 4°C. At monthly intervals, samples were blended to make 41.8° Brix Frozen Concentrated Orange Juice. The enzyme-treated samples had lower viscosity than those mechanically treated. Vitamin C retention levels were 〉 94% after 6 months storage at 4°C. Taste evaluations rated the product ‘very good’ and furfural levels were well below that which indicates off flavors. Browning tended to increase with storage time and temperature.

    Notes: Eight beef/pork ground meat blends were made from mature (cows or sows) and youthful (steers or barrow) beef and/or pork lean. Blends were stored at — 27°C for either 14 or 150 days. Storage time decreased overall desirability scores of blends made with 20% pork fat and 80% youthful beef lean. No differences were found for flavor or overall desirability scores within the 14-day storage treatment. The consumer panel did not detect differences among treatments for source of fat or species. Results indicated beef/pork patties containing 40–80% mature lean and a minimum of 10% beef fat were equal to all-beef controls (100% beef patty) for visual and palatability traits.
