    An Evaluation of Sources of Nitrogen as Causes of Ground-Water Contamination in Nassau County, Long Island (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 18 (1980), S. 0 
    Details
    ISSN: 1745-6584
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Energietechnik , Geologie und Paläontologie
    Notizen: An evaluation of sources of nitrogen in an urban area indicates that it may be difficult to distinguish effects on the quality of underlying ground water. In Nassau County two principal sources of nitrogen are human waste water and fertilized turf. The effects of these sources, combined with other sources such as domestic animals and precipitation, are such that management of one source, i.e. the removal of waste water via sewers, may be less effective than expected.

    Performance of a Scraped-Surface Heat Exchanger Under Ultra High Temperature Conditions: A Dimensional Analysis (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 47 (1982), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Performance characteristics of a pilot-scale scraped-surface heat exchanger (Contherm Model 6 × 2) under UHT operating conditions were evaluated. Outlet temperature and overall heat transfer coefficient (U) were significantly affected by rotational speed of the blades, mass flow rate of feed, feed inlet temperature, steam pressure and solids content of the model low-acid liquid food (soy extracts). The scraping action of the blades greatly improved the performance up to about 350 rpm; higher blade speeds had little or no effect and sometimes decreased U values. Application of dimensionless models showed that the effect of axial Reynolds number (ReA) on the Nusselt number was more significant in the turbulent regime (ReA 〉 1800), while rotational Reynolds number above 105 had a significant effect at all values of ReA between 1200 and 3700. At very high values of the Taylor number (〉 1010) when laminar axial flow conditions prevailed, Nusselt number decreased with increase in rotational Reynolds number.

    Phenolic Antioxidants of Soy Protein Hydrolyzates (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 47 (1982), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Soy protein hydrolyzate (SPH) was investigated to identify the phenolic compounds responsible for antioxidant activity. Three isoflavones–genistein, daidzein, and glycitein–were found in SPH. These are the same isoflavones that have been identified in raw soybeans. No isoflavone glycosides were found in SPH. The phenolic acids found in SPH were caffeic, ferulic, p-coumaric, syringic, vanillic, gentisic, and p-hydroxybenzoic acids. The compounds were identified by TLC, GLC and UV spectra. The isoflavones were confirmed by their mass spectra.

    EVALUATION OF SOME NATURAL AND SYNTHETIC PHENOLIC ANTIOXIDANTS IN LINOLEIC ACID MONOLAYERS ON SILICA (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 42 (1977), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Some naturally occurring and synthetic phenolic antioxidants have been evaluated in a dry model system simulating the exposure of lipids in freeze-dried membranes of whole tissue foods. The system is a linoleic acid monolayer on activated silica gel autoxidized at 80°C in dry air. The system is dry and porous and the demonstrated monolayer adsorption and restricted translational mobility of the lipid present a plausible model of freeze-dried membrane characteristics. Although relative effectiveness of the common antioxidants in this system has some similarities to the reported order in other dry systems, there are notable exceptions. For example, butylated hydroxyanisole is by far the most effective antioxidant in the silica system whereas it is reported to be much less effective than propyl gallate in bulk oils and some other dry systems. Thus, special conditions appear to modify antioxidant effectiveness in the lipid monolayer on silica.

    DISCOLORATION OF CHILLED SWEET POTATO [Ipomoea batatas (L.) Lam.] ROOTS: FACTORS RELATED TO CULTIVAR DIFFERENCES (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 41 (1976), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Roots of sweet potato cultivar Jewel, and two unnamed selections (213 × 228–1, and 2.57 × 255-8) were stored at 5°C or 14°C for 10 wk. Increased discoloration of certain cultivars of chilled sweet potato roots is apparently not due to an increase in the amount of extractable peroxidase or chlorogenic acid oxidase activity. Chilled tissues of 213 ×228–1 discolored and showed an increase in pH and chlorogenic acid. Chilled tissues from roots of 257 × 255-8 exhibited an increase in pH, but did not increase in chlorogenic acid content and were only slightly discolored. Tissues of Jewel changed little in pH or chlorogenic acid content and discolored the least of the three cultivars. Chlorogenic acid discolored under the influence of high pH. The data indicate that differences among cultivars in discoloration resulting from chilling injury may be due to differences in tissue pH and chlorogenic acid content.

    TEXTURAL QUALITY PREDICTION OF REHEATED FROZEN FRENCH FRIED POTATOES BY OBJECTIVE TESTING OF RAW STOCK (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 41 (1976), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Research is described which evaluates and relates a simple Durometer test of raw potato lots with instrumental texture measurements and sensory panel evaluation of oven-reheated frozen French fried potatoes. Statistical evaluation of the mean data shows no difference between the Idaho and Maine Russet Burbank samples for any of the measurements. Durometer means were significantly correlated with shear press measurements and all shear press values were significantly intercorrelated. The large correlation coefficients between Durometer readings and other measurements indicate that Durometer evaluations can be used to predict from the raw tubers the shear press measurements and overall moistness, crust crispness and internal mealiness of oven-reheated frozen French fried potatoes. Further work is necessary with other source and variety combinations before a general prediction statement can be made.

    Spontaneous occurrence of a synchronous hermaphrodite in the banded killifish, Fundulus diaphanus (Lesueur) (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 22 (1983), S. 0 
    Details
    ISSN: 1095-8649
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: An intersex specimen of the banded killifish, Fundulus diaphanus, was encountered during the analysis of the annual gametogenic cycle of this species. The simultaneous presence of mature spermatozoa and ova suggests that the potential for self-fertilization existed in this fish. The spontaneous occurrence of this intersex individual, although a rare event, indicates the potential for the development of the synchronous hermaphroditic condition under natural environmental conditions in this normally gonochoristic species.
