    Chemical and sensory changes in iced Nephrops norvegicus as indices of spoilage (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Changes in trimethylamine (TMA), total volatile bases (TVB), hypoxanthine and pH, and in cooked odour, flavour and texture have been followed during the iced storage of Nephrops norvegicus at approximately monthly intervals in order that seasonal variations could be investigated. None of the chemical methods investigated could give a prediction of age-in-ice to a standard error of less than 2 days. Initial TMA and TVB figures were significantly higher than other published figures.

    The two-factor triangle test (1982)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of food science & technology 17 (1982), S. 0

    Notes: The triangular test, commonly used in sensory tests of food quality, is generally interpreted on the assumption that the probability of a correct selection is the same for all assessors, and independent for separate trials leading to the use of the binomial distribution in setting up tests of significance. Only when there is no real discrimination is it true that using one taster n times is the same as using n tasters once, the basis for the column heading ‘number of tasters or tastings’ in published tables of significance. This paper attempts to remove this assumption by the use of the beta-binomial distribution, and suggests an interpretation in which the chance of success is different between and within assessors so that a two-factor analysis becomes possible. A set of data relating to the flavour of fish has been reinterpreted in these terms.

    Notes: Two sensory methods (General Appearance and Raw Odour) and two instrumental methods (Torry Fish Freshness Meter and Intelectron Fish Tester V) were tested on Aberdeen and Hull Markets. the variability of each method, comparisons between the methods and the time required to carry them out under market conditions were obtained. the instrumental methods (particularly the averaging version of the Torry instrument) are the most economical to operate.

    The connective tissues of fish. V. Gaping in cod of different sizes as influenced by a seasonal variation in the ultimate pH (1972)
    Oxford, UK : Blackwell Publishing Ltd

    Details
    ISSN: 1365-2621
    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: Small cod often gape more than large cod, but the size relationship, clearly seen in summer and autumn, disappears and may even be reversed in the winter and spring. This is probably because of variations in the post-mortem pH values of the two size groups, which can sometimes over-ride the size effect.

    The construction of grading schemes based on freshness assessment of fish (1976)

    Notes: Standard acceptance sampling schemes can be modified for use in grading, where grades are defined by one or two boundaries and a percentage permitted to fall below the lower boundary. Schemes are constructed to grade fish by freshness, using sampling by attributes or by variables, where the method of assessment is Raw Odour. When another method of testing, such as the Torry Fish Freshness Meter, is used, it is not sufficient in the attributes scheme to convert to new grade boundaries; the corresponding percentages falling below the grade boundaries for the new test must be determined. The procedures for deriving a scheme are not restricted to grading offish, but may be applied to any similar quality control situation.

    Evaluation of Partially Defatted Chopped Beef in Fermented Beef Snack Sausage (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 56 (1991), S. 0

    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: Five levels (0, 5, 10, 15, 20%) of partially defatted chopped beef (PDCB) were substituted for lean in fermented beef stick sausage to evaluate changes over a 90 day period (24°C). Replacement of 0, 5, 10, 15, and 20% of the lean with PDCB did not affect percentage of fat, moisture, protein, moisture:protein ratio, or aw of the final product. TBA values were different (P〈0.05) between storage periods, but were all lower than those associated with oxidative rancidity. Warner-Bratzler shear values increased incrementally with increasing PDCB but were still within acceptable limits. Sensory profiles indicated that concentration of PDCB in the formulation had no effect on aroma, mouthfeel, taste, or texture of the product over storage time.

    Difficulties encountered in the search for the etiologic agents of destructive periodontal diseases (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of clinical periodontology 14 (1987), S. 0 
    Details
    ISSN: 1600-051X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Abstract The present paper outlines some of the difficulties encountered in the search for the etiologic agents of destructive periodontal diseases. These include technical problems such as acquiring an appropriate microbial sample, as well as difficulties in the dispersion, cultivation and identification of isolates in that sample. Many of these difficulties are currently being successfully addressed. A second set of problems is more conceptual in nature. These include difficulties in distinguishing between periodontal diseases and determining the state of activity of periodontal lesions. In addition, complexes of organisms and/or sequences of species may be involved in the progress of lesions. A further problem is encountered in attempting to distinguish overgrowths of opportunistic species from increases in proportions of true pathogens. Finally, it appears likely that different infections occur at the same time in a single oral cavity. The technical and conceptual difficulties eventually filter down to the data analytical step and present numerous problems to the analyst. With all of these difficulties in mind it is not surprising that the etiologic agents of destructive periodontal diseases are not clearly defined. However, improvement in technological assessments of the microbiota and clinical evaluation of the disease should permit reasoned approaches to be taken. The delineation of the etiologic agents of destructive periodontal diseases will be, of necessity, a multistage iterative process. Etiologic agents will be suggested by predominant cultivable studies and hypotheses concerning subsets of these agents tested using more specific procedures such as selective media, immunofluorescent techniques or DNA probes. Etiologic agents will be verified or discarded by such procedures. When new lesions are found without recognized pathogens, the process will iterate back to the predominant cultivable methodology again.

    Diagnosis of periodontal disease activity by detection of key microbial antigens (1994)

    Notes: Abstract. This paper reviews the development of various rapid microbial identification techniques and their potential role in the diagnosis of active periodontal tissue destruction. It also explores the concerns expressed by some, that although these techniques offer enormous promise as research tools, validation and translation of test results to clinical diagnosis, prognosis and treatment planning are still problematic. It may be premature to recommend these tests to clinicians in practice. Further longitudinal studies are required to establish the best use of these techniques in a clinical setting.

    Notes: [Auszug] The vaccinia virus tk locus4'17 was chosen as a site of insertion for foreign DNA, primarily because it provides an efficient method of selecting infectious recombinants6'17. However, the possibility that this would lead to attenuation of virus virulence was considered because of data obtained with ...
