Some Factors Influencing Ante-Mortem Changes In Muscle: A Brief Review, S. C. Seideman, S. H. Cohen, J. V. Schollmeyer

Food Structure

Ante-mortem changes to muscle microstructure are influenced in many ways. During pre-natal cell differentiation and growth , myoblasts develop and mature into cells with quite different characteristics. Incorporated into the genome of these cells is the ability to synthesize a wide variety of filaments which occupy specific niches within each myofibril. During post-natal development , depending upon the particular precursor cell lines, different fiber types are produced. These are especially important in contributing to the ultimate palatability of meat. In this paper several factors which influence ante-mortem changes to muscle microstructure are discussed. While some of these are better understood …

Preliminary Evaluation Of Lectins As Fluorescent Probes Of Seed Structure And Composition, S. Shea Miller, S. H. Yiu, R. G. Fulcher, I. Altosaar

Food Structure

Several commercially available fluoresceinisothiocyanate and rhodamine isothiocyanateconjugated plant lectins have been applied to cereal and oilseed tissues to permit identification and localization of specific structures and carbohydrates by fluorescence microscopy . Ulex europeaus Agglutinin I (UEAl) and Ricinis communis Agglutinin I (RCA I) showed specificity for the amyloids in rapeseed cotyledonary cell walls . Wheat Germ Agglutinin (WGA) bound to rapeseed coat mucilage, as well as fungal hyphae in infected wheat . Lens culinaris Agglutinin (LCA) bound only to starch in cereal sections, and at higher magnifications of isolated starch granules , the annular structure was clearly visible.

Studies On The Microdistribution Of Aerobic Enzymes And Myoglobin In Pork, H. J. Swatland

Food Structure

Techniques were developed to study the microdistribution of aerobic enzymes and myoglobin directly on the surfaces of slices of meat. Despite its solubility, the in vivo distribution of myoglobin was preserved post mortem and, in pork, the distribution of myoglobin followed the distribution of aerobic muscle fibers. Aerobic fibers were grouped centrally in their fasciculi. Differences in oxidative enzyme activity between central and peripheral fibers within fasciculi were detected by staining with methylene blue in an atmosphere with controlled levels of oxygen and nitrogen. Within individual aerobic fibers, there was a radial gradient of SOH (succinate dehydrogenase) activity with more …

Processing Effects On Meat Product Microstructure, Glenn R. Schmidt

Food Structure

Animal species, meat ingredient properties, comminution equipment, mechanical action, product composition, type and level of non-meat ingredients, and thermal processing greatly affect the structural and organoleptic properties of meat products. However, additional research in the area of restructured meat products, meat protein functionality and lipid properties in meat products remains to be done. The interaction of meat proteins with lipids, water and ions should be further investigated. Considerable control of raw materials, mechanical action and heat processing is essential to make research applicable to product and process development.

The Effect Of Salt And Pyrophosphate On The Structure Of Meat, C. A. Voyle, P. D. Jolley, G. W. Offer

Food Structure

Our obective was to determine whether or not salt and pyrophosphate have the same effect on the structure of pieces of meat as they have on isolated myofibrils. Blocks of pig M. longissimus dorsi were incubated in solutions of sodium chloride at pH 5.5 or sodium chloride plus sodium pyrophosphate at pH 5.5 or 8.0. The blocks were obtained from fresh (24h post- mortem) or aged (72h post-mor tem) muscle and incubated for 5 or 24h with minimal agitation. There was considerable uptake of water by the tissue especially at the higher pH and longer times.

Log Cabin Studies: The Rocky Mountain Cabin, Log Cabin Technology And Typology, Log Cabin Bibliography, United States Department Of Agriculture, Forest Service

Forestry

While conducting fieldwork in southern Idaho during the summer of 1980, I came upon numerous examples of a type of cabin not previously documented. This report attempts to determine how this type fits with other known cabin types, and to find its place in present theories about American vernacular architecture. By making use of extant reports, historical photos, and archeological site forms, it is apparent this cabin type can be found throughout the Rocky Mountain region. Along with other Western studies, this report attempts to show that vernacular construction patterns in the Western United States differ from those present in …

An Analysis Of Microstructural Factors Which Influence The Use Of Muscle As A Food, R. G. Cassens, C. E. Carpenter, T. J. Eddinger

Food Structure

Study of structure of muscle provides information on the location and arrangement of various components and the changes which may be inflicted upon them. The structura l features of muscle have been descr ibed in detail down to the molecular level, but rega rding its use as a food, special interest centers on the connective tissue component and on myofibri llar proteins . Muscle comprises about 1/3 of the live weight of the a ni mal and is not static , but rather is subject to major changes in properties associated with growth, repair and se nescence. It is apparent …

Artefacts In Conventional Scanning Electron Microscopy Of Some Milk Products, Miloslav Kalab

Food Structure

Artefacts develop due to changes in the microstructure of the sample under study because of inappropriate preparatory steps and/or due to distortion of the images of properly prepared samples during operation of the microscope. Of a wide variety of possible artefacts. only those occurring mast frequently have been selected and ilustrated with micrographs. In milk powders, the most common artefacts are the recrystallization of lactose in a humid atmosphere, "1 ine" and "dark-area" charging artefacts, and electron beam damage. In moist milk products, artefacts may arise at any preparatory step, such as sampling, fixation, dehydration and critical-point drying or freezing …

The Role Of Gap Filaments In Muscle And In Meat, R. H. Locker

Food Structure

The neglected "gap filaments" are now beginning to receive close attention in several centers, in terms of organisation, composition and function. The author's model for their connections gave them a role as cores to A-filaments. This review attempts to weigh the implications of such a role, and relevant evidence, old and new. New ideas arising largely from PAGE*and immunochemkal studies on candidate proteins, and from the developing concept of the cytoskeleton, are considered.

The author's theory of meat tenderness, based on G-filaments, has been tested by PAGE studies on changes in the large structural proteins (particularly titin and nebulin) during …

A Report On A Pilot Study On Cattle Grazed Patches In Herbaceous Vegetation, Victor Povilaitis

Undergraduate Honors Capstone Projects

Since the late 1960's, the term station (Goddard 1968), feeding station (Novellie 1978, Underwood 1982), and feeding site (Underwood 1983) have been used to describe the area in front of a foraging animal in which it can access forage without moving its front legs. The area is a hypothecial semicircle in front of the grazing animal, but the vegetation actually impacted by defoliation may be considered a "grazed patch," which may be the sum of several feeding stations. As animals graze the vegetation in an area, grazed patches are created. Presently, it is undocumented if such patches influence the behavior …

Vicuñas And Pastoralists On The Peruvian Altiplano, Rachel Walker

Undergraduate Honors Capstone Projects

Many articles, government publications, and a fairly lengthy book have been written about the vicuña (hereafter vicugna), as can be seen by the bibliography, which is in no way exhaustive. What I try to do here is bring together several factors that have not, to my knowledge, been documented in one article; the sociological and cultural aspects of the altiplano (high plains) community which is affected by the PEURV (Proyect Especial por la Utilization Racional de la Vicugna); some of the political and economic aspects of the campesino's life; the vicugna and its environmental adaption to the harsh puna (high …
