Effect of Processing Parameters on Texture, Composition and Applicability of High Protein Dairy Food
… flow properties of a novel High Protein Dairy Food (HPDF). HPDF was manufactured by an approach similar to that of manufacture of Halloumi cheese (a semi hard cheese originally from Cyprus). The effect of pasteurization condition, pH of acidification and homogenization were investigated on …

Characterizing Oxylipins in Human Milk Extracellular Vesicles
… (0.0485, 0.0425, 0.0371-fold, respectively). The other oxylipins considered significantly higher in human milk than EVs are 13-HDHA, 4-vii HDHA, 12,13-DiHOME, and 11,12-DiHET. This contribution is significant since selected oxylipins present in human milk EVs versus whole human milk may be …

Real-Time PCR Combined with DNA Barcoding for the Authentication of Red Snapper (Lutjanus campechanus) Fillets
<p>Seafood substitution is a worldwide problem due to factors such as limited monitoring coupled with complex supply chains. Red snapper (<em>Lutjanus campechanus</em>) is a highly valued and overfished species that is commonly substituted with other fish, such as tilapia, rockfish, and other …

Insects as a Sustainable Food Ingredient – Utilization of Carrot Pomace, Identification of Early Adopters, and Evaluation of Mealworm Acceptability
… require less land and resources and can utilize food by-products to grow. While insects are consumed by over 2 billion people worldwide, they are not widely accepted in developed countries like the United States because of their unfamiliarity and the perception of disgust associated with …

Optimizing Immersive Technology Condition for Measuring Consumer Perception and Acceptance of Food Products
… the way toward a new era in sensory and consumer science by enabling consumers to experience tasting of food samples in different environments, thus generating more realistic perception. However, little attention has been paid to developing a standardized and optimized methodology for conducting …

The Impact of Processing on the Content and Composition of Bovine Milk Extracellular Vesicles
<p>Bovine milk (BM)-based formula is an alternative for many newborns who do not consume human milk. BM contains extracellular vesicles (EVs), bioactive compounds involved in intercellular communication which regulate critical developmental processes in early life. It was hypothesized that the …

Labeling Compliance, Species Authentication and Net Weight Identification of Frozen Fish Fillets Sold in Grocery Stores in Southern California
<p>Proper labeling of seafood is important to prevent economic deception, promote consumer awareness, and prevent exposure of at-risk groups to certain allergens and toxins. The objective of this study was to investigate prepackaged frozen fish sold in Southern California for Country of Origin …

Effects of Cognitive Style on Food Perception and Eating Behavior
… or holistic tendencies of individuals in food, sensory, and consumer tests can impact food perception and associated behaviors. This dissertation aimed to investigate the impact of analytic-holistic cognitive styles of consumers in food situations. The first objective to accomplish this …

Efficacy of Ultraviolet Radiation to Control Lactic Acid Bacteria in Wine Must
The use of shortwave ultraviolet (UV<sub>c</sub>) radiation to control lactic acid bacteria (LAB) in wine production was studied. A simulated wine sterilizer was built using a commercially sourced ultraviolet (UV) sterilizer commonly used in aquariums and ponds. After growing cultures in test …

The Impact of Dietary Protein Supplementation as Part of a Time Restricted Feeding Eating Pattern on Sleep, Mood, and Body Composition in Adults with Overweight or Obesity
<p>Obesity in the United States continues to increase, and effective, long-term weight loss strategies are limited. Time restricted feeding (TRF) is a dietary intervention that has potential to serve as an effective long-term weight loss strategy, however more data is needed to establish the …

Effect of Poor Sanitation Procedures on Cross-Contamination of Animal Species in Ground Meat Products
<p>While the presence of ≥1% of an undeclared species in ground meat generally used as an indicator of intentional mislabeling as opposed to cross-contamination, the actual percent of undeclared species resulting from cross-contamination has not been experimentally determined. The objective of this …

Essential Amino Acid (EAA) Regulation of Skeletal Muscle Protein Turnover with Age
<p>Skeletal muscle (SM) is vital for both long term health and quality of life. Recent research suggests an increase in catabolic signals with age triggers pathologic conditions, such as sarcopenia. Although results from in vitro studies model how EAA can regulate muscle protein synthesis (MPS), …

Evaluating Mislabeling of Raw, Ready-To-Eat Seafood Products in Orange County, California
<p>Raw, ready-to-eat (RTE) seafood products have become increasingly popular globally, but they are vulnerable to species mislabeling and substitution. DNA barcoding allows for fish species identification by extracting, amplifying, and sequencing a standardized gene target. A wide variety of fish …

Saponin Removal from Quinoa by Abrasion Processing
<p>Quinoa is coated with a thin layer of saponins, glycosylated triterpenoids, that produce a bitter flavor when consumed. The average saponin content in commercial varietals from Bolivia average around 2.7% saponins and organoleptic testing shows the threshold for noticing a bitter flavor is below …
