    Notes: Extracellular protease and lipase from Pseudomonas fragi significantly (P 〈 0.05) decreased color stability of sterile beef at 4°C and sterile beef extract at 4°C and 21°C. Concentrations of free fatty acids (FFA) in enzyme-treated sterile beef samples were significantly (P 〈 0.05) higher than in sterile controls held at 4°C indicating hydrolysis of glycerides by lipase from P. fragi. Concentrations of nonprotein nitrogen (NPN) and free amino acids in sterile beef extract treated with extracellular enzyme and held at 4°C and 21°C were significantly (P 〈 0.05) higher than in controls indicating proteolysis by protease from P. fragi. This was confirmed by SDS-polyacrylamide gel electrophoresis of enzyme-treated beef extract stored at 4°C for 6 days. Sephadex G-100 gel filtration and poly-acrylamide disc electrophoresis indicated that the molecular size and electrophoretic mobility of the protease and lipase were similar.

    Notes: Efficacies and optimum application conditions of three sanitizers (chlorine, 200–250 ppm; acetic acid, 4.0%; and quaternary ammonium, 3.78 g/liter) were determined. Variables were three rates of flow of sanitizer (1.7, 3.4 and 6.8 liters/min), washed and unwashed meat, warm (38°C) and cold meat (3.3°C), and two pressures of sanitizer application (3.5 and 14.0 kg/cm2). Results were averaged over other variables providing the following data for individual variables. Acetic acid gave a high initial average decrease in counts (−1.47 log), and counts decreased (−1.79 log) up to 48 hr after sanitization. Chlorinated solution caused an initial mean difference of −0.31 log and a difference after 48 hr of 0.53. The quaternary ammonium compound produced differences of −0.79 and −0.03 log in immediate and 48-hr counts. Acetic acid and hypochlorite were nonselective, but the quaternary sanitizer allowed more oxidase positive, nonfermentative bacteria to survive.

    Notes: Protein concentrations in milk were compared using a modified Lowry and the micro-Kjeldahl methods. Correlation coefficients for absorbance (Lowry) vs protein (Kjeldahl) were 0.925, 0.904 and 0.899 for individual Holstein, individual Guernsey and bulk raw milk samples, respectively, whereas, the R2 was 0.9998 for samples of 2.5-4.0% protein prepared from three brands of nonfat dry milk. Added lactose, up to 16 mg/ml milk, did not interfere in the test. Storage at 4°C for up to 6 days was without effect. However, whey proteins had a lower specific absorbance than did casein. The standard deviation of differences among triplicate Lowry tests was about one-third of that for duplicate micro-Kjeldahl tests.

    Notes: A procedure was developed to entrap culture bacteria using a two-phase (water/oil) system. It consisted of 3% sodium alginate mixed with microbial cells and suspended in an oil bath containing 0.2% Tween 80. While stirring at 200 rpm, calcium chloride (O.OSM) solution was added to break the water/oil emulsion and form calcium alginate gel. The calcium alginate beads containing microbial cells had mean diameters of 25–35 μm (range S-100 μm). The entrapped microbial cells were released completely from the drop shaped beads by gentle shaking in 0.lM phosphate solution (pH 7.5) for 10 min. About 40% more lactobacilli survived freezing of ice milk when they were entrapped in calcium alginate than when they were not entrapped.

    Notes: A mixture of 2% acetic, 1% lactic, 0.25% citric and 0.1% ascorbic acid was applied to beef core samples of muscle inoculated with bacteria. Experimental variables were concentration and temperature of mixed acids and type of microorganism. Overall, an increase in either mixed acids concentration (0 to 3%) or temperature (20 to 70°C) resulted in reductions in counts of about one logi0 for aerobic bacteria and S. ryphimurium, less than one log10 for Enterobacteriaceae, and about one-half log10 for E. coli. Initial meat surface pH dropped to 4.3 after treatment with 3% mixed acids solution but rose to 5.2 after 24 hr. Overall, this mixture of acids performed about the same as acetic acid or lactic acid under the same conditions.

    Notes: Vanilla flavor frozen desserts were made to be similar in composition except for the fat. Canola and soybean oils were combined with milk fat to provide fatty acid ratios of 1:1:1 and 3:2:1 (saturated: monounsaturated:polyunsaturated), whereas the milk fat control had a ratio of 24:8.6: 1. Sensory, physical and chemical tests indicated minimal differences between the control ice cream and the dessert with the 3:2:1 ratio. However, product with the 1:1:1 ratio was described as oily and oxidized in flavor. It melted faster, was softer in the penetration test and coarser in texture than the ice cream control.
