    Notes: : Wheat breads were prepared to contain 0%, 2%, 6%, or 12% non-solvent extracted texturized soy flour (NSETSF) or solvent extracted texturized soy flour (SETSF) to evaluate their effects on instrumental and sensory characteristics. To compare the effects of added dough enhancers versus those contained in lip id-extracted soy flour, a sucrose ester was included in some formulations. Both soy flours produced comparable loaves relative to percent inclusion. Texture analysis and trained sensory panel evaluation indicated that SETSF loaves were softer than NSETSF loaves. The consumer panel found bread with 12% NSETSF similar to the control. Texturized, lipid-extracted soy flours added to wheat breads produced a “sucrose ester”-like property.

    Notes: : Effects of pH, muscle, and storage time on the ability of vacuum-packaged pork chops to bloom were investigated. Low pH samples exhibited more change in color measures during the 30 min blooming period than did the medium and high pH samples. The low pH sample bloomed more rapidly and to a greater extent than medium and high pH samples. Among the 3 muscles, Longissimus had the highest, while Semimembranosus had the lowest a* value and hue angle changes. Overall, refrigerated storage of vacuum packaged pork for 7 d or more resulted in more efficient blooming when pH was low. The ability of vacuum-packaged pork to rebloom is necessary for the meat to regain the consumer-expected pink-red color after opening the vacuum bag.

    Notes: The objectives of this study were to survey consumer attitudes about the safety of the food supply in general, relate general concern levels with groups of specific items of concern, regulatory issues and prioritization of food safety funding areas, and to compare these results with results of a similar survey conducted in this lab in 1994. Factor analysis of 360 consumer responses showed six factors underlying the 31 specific items evaluated on individual 5-point scales (1 = no concern, 5 = very strong concern). MANOVA using general level of food safety concern (independent variable) were significant. Univariate tests showed that as general level of concern with food safety increased, so did concern with chemical issues (artificial colors, pesticide residues, hormones, preservatives, irradiated foods, excessive processing of foods, and plastic packaging), spoilage issues (restaurant sanitation, shelf-stable foods, pasteurized foods, refrigerated, prepared foods, improper food preparation, microbiological contamination and nutritional imbalances), health issues (vitamin, calorie, carbohydrate, fat, cholesterol and sugar content), regulatory issues (pesticide safety, fish and imported food inspection, and health labeling of food), deceptive practices (naturally occurring toxins, food ingredients associated with allergies and weight reduction diets advertised as healthy) and information issues (availability of detailed information at stores, markets and restaurants).

    Notes: Myofibril gels with 5, 7, or 10% protein and 2% NaCl were prepared from pork, beef, fish, chicken and turkey muscles using a heating rate of 0.7°C/min and pH 6.0 to compare the thermal gelation properties of myofibrillar protein from different species. The force required to rupture gel (Pf), force required to move plunger through gel (Fp), viscosity index (Ni), and elasticity (Ea) increased and cooking loss decreased with increasing protein contents. Myofibrils of chicken breast and thigh had lower and fish and turkey thigh had higher cooking loss at protein contents of 7% or 10%.

    Notes: A surimi-like material was made from finely minced beef or pork by water washing followed by screening to remove connective tissue. Changes in component proteins, amino acid composition and vitamin, mineral and cholesterol content occurring during preparation were investigated. Total amino acid nitrogen contents of water-washed beef and pork were higher than those of the respective muscle by 7% and 6.5%. Among 16 amino acids measured, histidine and glycine decreased in both water-washed beef and pork, while others increased compared to original muscle. Thiamin content decreased after washing. Surimi-like beef and pork had less cytoplasmic minerals (K, Na, Mg) but more minerals associated with proteins or subcellular organelles (Ca, Cu, Zn, Fe). Fat content decreased, although cholesterol concentration was not changed by washing.

    Notes: Ground beef chuck (15% fat) was packaged (500g) in vacuum bags, Saran WrapTM overwrapped with aluminum foil or polyvinyl chloride (PVC), exposed to retail display light (4°C) for 24 hr and then held frozen (−18°C) for 52 wk. Instrumental and visual color of PVC-packaged beef was affected most by display and by frozen storage. During frozen storage, as oxygen permeability of packaging material increased, TBA, visual brownness, and metmyoglobin increased while visual redness, acceptability, a* value, red color contributed by oxyrnyoglobin, and deoxymyoglobin decreased. Location on the meat block (exterior vs interior) affected (p〈0.05) visual red and brown color, lightness, and acceptability, L*, a*, and b*, and TBA values.

    Notes: The objective of this study was to assess the survival of Escherichia coli K-12 in solutions of ingredients used for enhancing meat products and to evaluate the effect of potentially lethal temperatures. Enhancement solutions were prepared to contain water only (W); water + salt + phosphate (control, C); water + salt + phosphate + sodium lactate (SL); water + salt + phosphate + sodium acetate (SA); or water + salt + phosphate + lactate + diacetate (SLDA). The SLDA solution resulted in the highest log reduction of E. coli K-12 followed by SL. Heating solutions to 70 °C resulted in about a 4 log reduction, whereas heating to 60 °C produced about a 2 log reduction. For samples with an initial microbial load of 106 colony-forming units (CFU)/mL, addition of SL and heating to 50 °C resulted in about a 2 log reduction, addition of SA gave 〈0.5 log reduction, whereas addition of the SLDA combination produced a 〉 4.0 log reduction. The SLDA combination could allow for lower heating temperatures to achieve similar microbial reductions.

    Notes: Gel forming ability, measured by cooked gel hardness, and water-holding capacity of surimi-like pork were enhanced by addition of NaCl at 1.5 or 3% although 4.5% or 6% NaCl did not further increase hardness. Cooked gel strength was unaffected by freezing of beef or pork surimi-like materials for 48 hr. Addition of cryoprotectants (3% or 6% sorbitol, 3% glycerol, or 3% sucrose) before freezing had no effect on gel forming ability. Gel hardness was not increased by preheating prior to cooking. Preheating surimi-like pork at 50°C resulted in formation of weaker gels which corresponded to myosin proteolysis. Myosin heavy chain (mw 200 kD) decreased, and new peptide fragments of mw about 138 kD, 128 kD, 120 kD, 86 kD, 77 kD, and 64 kD appeared. Proteolysis was salt-dependent and occurred at pH 6.8–7.5.

    Notes: Ground pork, 30% fat, was packaged in 454g units in Cryovac bags heat scaled under vacuum (V), Saran Wrap™ (S), aluminum foil (A), Saran™ overwrapped with aluminum foil (SA), and polyvinyl chloride (PVC) and frozen 13, 26, or 39 wk at − 17°C. TBA values increased over time regardless of packaging. Those materials that excluded oxygen delayed lipid oxidation longest. Red color (CIE a* value and % reflectance difference at 630 and 580 nm) decreased over time; this was greater on exterior than interior of the meat block. Materials that excluded oxygen prevented loss of red color during the first 26 wk storage. Changes in redness and TBA appeared unrelated to pH. Changes in L* and b* values did not appear related to packaging treatment or storage time.
