Food and Machinery
Fruit bodies of Volvariella volvacea V23 strains were stored at 15 ℃ after harvest. Morphological and physiological indexes were measured at 0, 12, 24, 36, 48, 60, 72 and 96 h after storage, respectively. The results showed that the sensory score of V. volvacea fruit bodies decreased with storage time, while weight loss rate, relative electric conductivity, and malondialdehyde content gradually increased with the prolongation of storage time. The contents of soluble sugar and protein were in a state of continuous decomposition and synthesis. No significant change was found in the activities of acid protease, while the activities of the …

The antioxidant capacity of dried Agaricus bisporus mushrooms (DAB) in beef has previously been assessed. However, interactions between lipid oxidation products, mushroom polyphenols, and bovine proteins present in beef to explain the mushroom's antioxidative effect, has not been determined. Oven-dried or lyophilized DAB with and without 15 g NaCl/kg beef (1.5%) or 20 g NaCl/kg beef (2%) were added to sarcoplasmic protein homogenates from top round beef. Malondialdehyde and volatile aldehyde binding to sarcoplasmic protein (SP) were monitored. Oven dried had 64% higher total phenolic compared to lyophilized DAB, leading to ∼50% lower malondialdehyde content in beef with oven …

Candida albicans inhabits the gastrointestinal tract dormant commensal member but can become an opportunistic pathogen when the host microflora or immune system is compromised. Adhesion to a biological or synthetic surface, followed by a morphological change from the yeast to hyphae phenotype. Biofilm formation is becoming a common occurrence on types of medical devices. Because C. albicans resistant to commonly available anti-fungal drugs is increasing, innovative treatments are critically needed. Phenolic compounds are promising anti-fungal synergists. Supina grass was used as the complex matrix as it is abundant and highly sustainable source of phytochemicals even though grass cuttings are typically …

We recently reported that epicatechin, a bioactive compound that occurs naturally in various common foods, promoted general health and survival of obese diabetic mice. It remains to be determined whether epicatechin extends health span and delays the process of aging. In the present study, epicatechin or its analogue epigallocatechin gallate (EGCG) (0.25% w/v in drinking water) was administered to 20-mo-old male C57BL mice fed a standard chow. The goal was to determine the antiaging effect. The results showed that supplementation with epicatechin for 37 wk strikingly increased the survival rate from 39 to 69%, whereas EGCG had no significant effect. …

Graduate Theses and Dissertations
Campylobacter jejuni infection in humans is strongly associated with the handling and consumption of contaminated poultry products. Interventions reducing C. jejuni contamination in poultry would reduce the risk of subsequent human infections. In the first study, the efficacy of a Generally Recognized as Safe (GRAS) compound, eugenol (EG; derived from cloves), as an antimicrobial dip treatment to reduce C. jejuni in postharvest poultry was evaluated. The antimicrobial efficacy of EG was studied in suspension, emulsion and nanoemulsion delivery systems. EG suspension reduced C. jejuni counts with the greatest reduction of >2.0 Log CFU/sample for the 2% dose of EG (P

Effects Of Serving Temperature On Sensory Perception And Acceptance Of Brewed Coffee, Matthew James Chapko
Graduate Theses and Dissertations
Coffee continues to be one of the most widely consumed beverages worldwide. How an individual perceives a cup of coffee is impacted by a plethora of factors including origin, growing climate, roasting level, and consumption habits. This thesis utilized both trained descriptive panelists and untrained consumer panelists to analyze how serving/consumption temperature modulates sensory perception of brewed coffee in regards to appearance, aroma, flavor, taste, and mouthfeel. Three varieties of coffee (Colombia, Ethiopia, and Kenya) were brewed and served to panelists at four temperatures: 70, 55, 40, and 25 °C. In one study (Study 1, Chapter 3), results from descriptive …

Influences Of Intrinsic And Extrinsic Hand-Feel Touch Cues On Sensory Perception And Emotional Responses Toward Beverage Products, Ragita Cantika Pramudya
Graduate Theses and Dissertations
Consumer perception of and preference toward products are influenced by intrinsic product-specific (e.g., product temperature) and extrinsic non-product-specific (e.g., packaging or container) characteristics. Besides communicating information between products and consumers to create expectations toward the content at the point of sale, packaging also influences sensory perception of the content during consumption. Previous cross-modal studies on packaging effects on the content had largely overlooked hand-feel touch cues. Touch closely relates to consumers’ emotional responses to and their quality evaluation of products. One way to manipulate hand-feel touch cues in a beverage consumption setting is to vary materials of cup sleeve, which …

Food Manufacturers are facing challenging times due to regulations such as the Food Safety Modernization Act (FSMA) requiring them to provide evidence they are producing safe foods. Food testing laboratories aid in the mitigation of food safety issues providing evidence that a manufacturers food safety system is acceptable. To perform these activities laboratories are required to adhere to certain standards such as ISO/IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories. However, implementation of ISO/IEC 17025 practices is challenging, especially for small and academic laboratories, due to lack of available guidance. A long-term goal of the University …
