    Notes: Microbial and chemical changes during iced storage of fillets from channel catfish (Ictalurus punctatus) with film overcropping, vacuum packaging, or vacuum skin packaging were determined by psychrotophic plate counts, thiobarbituric acid (TBA), free fatty acid, pH, and ammonia production. Vacuum-packaged fish had significantly lower (p 〈 0.05) psychrotrophic bacteria counts than overwrapped fish. A significantly higher free fatty acid content was also observed after week two in overwrapped samples. However, vacuum-packaged catfish had the same pH, TBA number, and ammonia production as overwrapped fish on the sampling days throughout three weeks of storage.

    Notes: The effects of temperature, time, and number of extractions on the color, gas chromatographic profile, and flavor characteristics of water extracted peanuts were determined. Temperature was the major factor which affected these attributes. Increasing the extraction temperature resulted in darker colored peanuts with less chroma, less raw peanut flavor, and more cooked peanut flavor. It also led to a significant decrease in flavor volatiles. Based on the results, the recommended conditions are to water extract at 90°C for 10 min three times to produce peanuts which arc light in color and bland in flavor.

    Notes: The feasibility of producing coffee whitener by spray drying peanut extracts was studied. The whiteners were spray-dried at 200°C using atomizer speeds of 15000, 25000, 35000 rpm and volumetric flow rates of 0.6, 1.2, 1.8 L/hr. Performance of the whiteners in coffee was evaluated vs commercial coffee creamers by a consumer panel. Objective tests for color, solubility, and moisture were performed. The liquid whitener had lower performance and sensory scores than commercial samples (p 〈 0.01). Recommended processing conditions for spray drying liquid whitener from peanuts at 200°C include atomizer speeds in the 15000-29000 rpm range and volumetric flow rates 〉 1.80 L/hr.
