    THE OUTPUT OF SWARDS ON COMMERCIAL FARMS IN RELATION TO FERTILIZER AND OTHER MANAGEMENT FACTORS (1965)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 20 (1965), S. 0

    Notes: Survey data collected during a grassland-recording investigation showed a strong positive correlation between nitrogen input and the output of utilized starch equivalent per acre. At the levels of output covered, sward type was not very important in relation to total yield. Herbage species were important for other reasons and the choice of seeds mixtures should be determined by factors such as earliness and lateness of growth and resistance to disease and drought. The survey showed that well-managed ley and permanent pasture are both capable of producing at a high level. A disturbing feature of the results was the low production of most spring resowings, primarily as a result of poor management. Although the records were obtained from an above-average group of farms, the results have general application. Potential responses to fertilizers may be even greater on less intensive farms, especially with regard to phosphate and potash. However, the level of production of a field will always depend finally on the level of management exercised by the farmer himself.

    Sensory Evaluation of High Vacuum Flame Sterilized Clingstone Peaches, Using Ranking and Signal Detection Measures with Minimal Cross-Sensory Interference (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    Notes: Seven peach varieties were canned conventionally with added syrup or added water and using high vacuum flame sterilization (HVFS) with and without added syrup. The treatments were assessed for sweetness, sourness, odor intensity, darkness of color, firmness by bite and firmness by visual appearance, using ranking and R-index measures. Cross-sensory interference was minimized by the excluding or reducing of the effects of inappropriate senses. Conventionally canned peaches were less firm to the bite but this did not correspond with visual appearance of firmness. Peaches canned with added syrup tended to be sweeter and less sour. Color and odor differences were less clear cut. Comparisons were also made with fresh peaches.

    Selected Rheological Properties of pH-Adjusted or Succinylated Egg Albumen (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Apparent viscosities of pH-adjusted or succinylated raw egg albumen were measured at 10, 20, and 30°C using a Haake rotary viscometer. Viscosities decreased with increasing temperature. Rheological power law model parameters indicated that as pH approached 5–6 and 11, albumen became more Newtonian. Control albumen (pH 9.0) and succinylated albumen were pseudoplastic. Intrinsic viscosities of DH 9.0, 10.0, and 11.0 albumens were 0.083, 0.092, and 0.102 dl/g, respectively, and that of succinylated albumend (0, 0.1, 0.2, and 0.4% w/w) were 0.052, 0.147, 0.149, and 0.184 dl/g, respectively. Apparent viscosities of coagulated albumen, measured by capillary extrusion, increased with pH but did not change with succinylation. Yield forces and rigidity moduli of these gels increased with pH but not with succinylation level.

    A Computerized Procedure for Estimating Chemical Changes in Thermal Process Systems (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: Chemical changes caused by heating in a continuous flow, helically coiled tube indirect UHT process system were evaluated and compared to a nonflow vat process system. A computerized procedure was developed to estimate the rates (R) and accumulated values (Fc) of chemical changes in the various stages of the UHT and vat thermal processes. The procedure could also be used to determine the conditions necessary to optimize quality and/or nutrient retention. Data were based on 300°F and 3.3 set holding time in the continuous process and 180°F for 30 min holding time in the vat system, Approximately 10% of the overall chemical changes occurred during the heating period for both processes, 88% and 87% during the holding periods, and 2% and 6% during the cooling respectively for the UHT and vat processes.

    Prevention of the Green-Gray Discoloration in Cooked Liquid Whole Eggs (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The prevention of the green-gray discoloration of cooked liquid whole eggs was studied. Acidic chelating agents were added to raw liquid whole egg samples at pH 8.50. Samples were cooked at 100°C for 20 min, held over a steam bath for 60 min, and then measured for color. Results show the following approximate optimum concentrations will prevent the discoloration at p = 0.05: acetic acid, 0.19%; citric acid, 0.17%; Na2EDTA, 0.029%; lactic acid, 0.27%; malic acid, 0.22%; monosodium phosphate, 0.34%; propionic acid, 0.26%; and succinic acid, 0.27%. It was also found that the average maximum pH attained by raw liquid whole eggs when stored at 3°C for 21 days was 7.93 ± 0.19. A taste panel indicated that there were no significant differences in overall acceptability with the Na2EDTA and the monosodium phosphate treatments. The citric acid treatment was not significantly different from the control in flavor acceptability. Other treatments were judged to be inferior to the control.

    Scoring vs. Comparative Rating of Sensory Quality of Wines (1965)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 30 (1965), S. 0 
    Details
    ISSN: 1750-3841

    Notes: One hundred and fifty wines of different types and regions were scored by 11 experienced judges by two methods (scoring and comparative rating). It was thought that the second method (which included a reference wine) would give more stable and consistent results than the standard method. For some categories of wines the standard method resulted in more stable and consistent responses, but for other categories the reverse is true. For some judges and for some categories of wines the two methods were practically identical. The reactions of the judges to the two methods varied greatly.

    Comparative Susceptibility of Chicken, Duck and Turkey Eggs to Microbial Invasion (1965)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 30 (1965), S. 0 
    Details
    ISSN: 1750-3841

    Notes: Duck eggs were the most susceptible to bacterial spoilage, and turkey eggs were at least as resistant as chicken eggs and in some experiments appeared significantly more resistant. Under storage for 6 weeks at room temperature, however, the ability to resist bacteria was essentially unchanged in duck eggs and very markedly lowered in chicken eggs. Similarly, duck eggs lost very little quality (Haugh units) upon prolonged storage, and chicken eggs lost interior quality much faster. Bacterial penetration studies of chicken and duck exterior structures with model systems demonstrated that the outer shell membrane was the least resistant, followed by the shell and then the inner shell membrane. No consistent or significant differences in bacterial penetration were found between chicken and duck eggs, although the inner shell membrane of the former was thicker than that of the latter. Egg albumen was implicated as a major barrier to bacterial egg spoilage; conalbumin was an important inhibitor in egg white.

    DISCOLORATION PROBLEMS IN MECHANICALLY DEBONED FISH (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 45 (1980), S. 0 
    Details
    ISSN: 1750-3841

    Notes: When fish are deboned in an “auger-type” deboning machine darkening of the minced product occurs. The objective of this work was to determine the cause of the discoloration. Two different reactions leading to discoloration were found to occur, one during processing and the other during frozen storage. The first discoloration occurred immediately after deboning and had a characteristic “grayness.” The second discoloration occurred during frozen storage and was characterized by the development of yellow to brownish colors. It was found that the gray discoloration was skin related and pressure dependent. The release of black pigments, melanins, from the fish skin was found to be the source of the initial gray discoloration.
