    Notes: Effects of incorporation of iota-carrageenan, sodium alginate (AL), and soy protein isolate (SPI) in comparison with control (CONT) on the textural and physicochemical properties of reduced-fat (15%) meat emulsions heated to various internal temperatures were investigated. Lower percent fat and water losses for treatments containing gums or soy protein isolate than those of CONT indicated that addition of gums and soy protein isolate could improve emulsion stability. AL had the greatest water-holding capacity at the higher endpoint temperatures (76.7 °C and 82.2 °C), which was possibly due to the formation of a heat-stable alginate gel. The SPI had the highest concentration of salt-soluble protein in either raw or cooked meat batter.

    Notes: : The physicochemical, textural, and quality characteristics of Chinese-style meatball (20% fat) containing varying levels of bacterial cellulose (nata) were evaluated. Cooking losses of nata-containing Chinese-style meatballs were higher than those of control (containing no nata and 20% fat [C20]). Raw nata-added batter had higher water-holding capacity than control, but the pattern was reversed after cooking. N10 (10% nata) and C20 had the highest springiness scores. Textural hardness and shear-force value were significantly higher for C20, but both attributes for nata-added treatments decreased with increasing nata levels. Addition of 10% nata to Chinese-style meatballs produced products with acceptable textural and sensory qualities. Nata showed potential as a functional ingredient in Chinese-style emulsified meat products such as Chinese-style meatballs.

    Notes: : Physicochemical properties and microbial stability of reduced-fat Chinese-style sausages packaged with various modified atmosphere packaging (MAP) systems were evaluated. With the exception of VAC (vacuum) treatment, the TBARS (thiobarbituric acid-reactive substances) values increased with increasing storage time. Treatments of C100 (100% CO2), C80 (80% CO2/20% N2), and C20 (20% CO2/80% N2) were higher in TBARS values than VAC and N2 (100% N2) after 2 wk of storage. The numbers of total plate counts, psychrotrophs, total anaerobes, or lactic acid bacteria increased slightly, though statistically insignificant, during storage, while N2 was numerically the lowest and VAC was intermediate. Vacuum packaging was more effective than other MAP in maintaining lipid and microbial stability of reduced-fat Chinese-style sausage. Keywords: reduced-fat, Chinese-style sausage, MAP, storage stability, vacuum packaging

    Notes: Rheological and gelation characteristics of a specific degree of deacetylation (dd 50 to 99) and concentration (0.5% to 1.5%) of chitosan and chitosan/SSP (salt-soluble protein) mixtures were studied. Results suggested that SSP thermal gelation was interfered with by the positive charges of amino groups of the chitosan molecule. Regardless of degree of deacetylation, increasing chitosan concentration caused stronger interference on SSP gelation and lowered complex modulus [G*]. Loss tangent of chitosan/SSP gel decreased with increasing temperature. Higher level (1.5%) of dd 99 chitosan had the lowest G*, which resulted from ionic interaction with SSP. SDS-PAGE revealed protein aggregation, indicating possible covalent bond formation.

    Description / Table of Contents: Zusammenfassung In einem Fluidsystem, das bei hohem Wärmefluß den Effekt des unterkühlten Siedens zeigt, findet der wesentliche Wärmetransportmechanismus in einer sehr dünnen Schicht statt, die zwischen der beheizten Oberfläche und den Dampfpolstern liegt und als „Unterschicht“ bekannt ist. Basierend auf den Gesetzmäßigkeiten des konvektiven Siedens unter dominierendem Einfluß der Wärmeleitung durch die Flüssigkeits-Unterschicht wurde ein theoretisches Modell zu Beschreibung des Wärmeübergangs bei unterkühltem Sieden entwickelt. Um nützliche Daten für die Simulation der in Leichtwasserreaktoren (LWR) herrschenden Bedingungen zu gewinnen, erfolgten die Experimente bei Aufwärtsströmung siedenden Wassers in einem senkrechten Rohr im Druckbereich 6,9 bis 15,5 MPa. Diese experimentellen Ergebnisse werden mit Vorausberechnungen nach dem erstellten Theoriemodell, sowie jenen nach fünf der bekanntesten Korrelationen verglichen. Für unterkühltes Sieden in Leichtwasserreaktoren zeigte sich hierbei, daß die Experimente am besten durch das neuentwickelte Modell wiedergegeben werden.
    Notes: Abstract In a subcooled flow boiling system at high heat flux, the major heat transfer mechanism places emphasis on a very thin liquid layer, known as the ‘sublayer’ which is trapped between the heated surface and the vapor blankets. Base on the convective boiling heat transfer dominated by the heat conduction through the liquid sublayer, a theoretical model for subcooled flow boiling heat transfer has been developed. To provide useful data in the simulation of Light Water Reactors (LWRs) conditions, heat transfer experiments for up-flow boiling water through a vertical tube at the pressure ranging from 6.9 to 15.5 MPa have been conducted. The experimental results are compared with the predictions of the present model and other five famous correlations. For the LWRs subcooled flow boiling, the comparison reveals that the present model show the best agreement with the measured data.
