Efficacy Of A Mushroom Derived Saltiness Enhancer In Increasing Saltiness And Consumer Acceptance In Low Sodium Applications, 2020 University of Tennessee, Knoxville
Efficacy Of A Mushroom Derived Saltiness Enhancer In Increasing Saltiness And Consumer Acceptance In Low Sodium Applications, Lindsay Jenkinson
Masters Theses
The average American consumes sodium at excessive levels resulting in a multitude of adverse health effects. To reduce these risks, it is imperative to lower consumption rates. When sodium is reduced in a product, the main effect is decreased saltiness and often corresponds with reduced consumer acceptance. In addition to addressing the issue of sodium reduction, attenuating effects such as reduced consumer acceptance is also of importance.
Consuming and perceiving food is a multimodal experience, involving tastes, smells, and trigeminal sensations to produce a singular percept of flavor. This is an example of multisensory integration. When stimuli through different sensory …

Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, 2020 University of Arkansas, Fayetteville
Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, Scarlettah Schaefer
Journal of Food Law & Policy
Food and technology have had a long and tempestuous relationship. Current methods of food production and processing in the industrialized world depend heavily on technological developments. However, all technologies are not created equal. Some can produce food that is safer, more sustainable, more nutritious, or longer lasting. Some can have the opposite effect: increasing opportunities for adulteration, increasing the difficulty in detecting food fraud, and contributing to both foreseeable and unforeseeable health or ecological costs. Increasingly sophisticated technologies often become less apparent to the average consumer. For example, consider irradiated meat or genetically modified foods as opposed to freezer storage …

Animal and Food Sciences Faculty Publications
The objective of these studies was to determine the effect corn fiber (CF), wheat bran (WB) and pectin (PEC) on basal ileal endogenous amino acid (EAA) losses in broiler chickens (Exp. 1) and cannulated pigs (Exp. 2) using the regression method. Semi-purified diets containing 100 g/kg of CF, WB, or PEC (broiler chickens) and CF or PEC (pigs) were fed to replicate cages consisting of eight birds per cage of 21-d-old broiler chickens and six replicates of pigs consisting of one pig per pen. Ileal endogenous His, Glu, and Pro losses were higher (p < 0.05) for CF and WB compared with birds fed diets containing PEC. Contrasts between CF and WB showed higher (p < 0.05) ileal endogenous nitrogen, total amino acid, His, Ile, Met, Glu, Pro, and Tyr losses in birds fed the CF diets (Exp. 1). Contrasts of EAA losses between birds fed the WB and PEC diets showed higher (p < 0.05) losses for His, Glu, and Pro. In the cannulated pigs, CF resulted in higher (p < 0.05) ileal endogenous His, Leu, and Tyr losses. In summary, CF induced higher ileal EAA losses in broiler chickens and cannulated pigs.

Point-Of-Decision Prompts Increase Dietary Fiber Content Of Consumers’ Food Choices In An Online Grocery Shopping Simulation, Kristina Arslain, Christopher Gustafson, Devin J. Rose
Department of Food Science and Technology: Faculty Publications
Only 5% of Americans consume the recommended amount of dietary fiber. In an online simulated shopping experiment, we examined whether a fiber-focused point-of-decision prompt (PDP) would influence consumers to choose food products that were higher in this important nutrient. We hypothesized that participants exposed to the dietary fiber PDP would choose products with more dietary fiber/serving than those who were not exposed to the PDP. The experiment was completed by 753 participants. Participants were randomly assigned to a condition in which they were not exposed to a PDP (the no-PDP condition), a personalized PDP, or PDP without personalization. Choices in …

Identification And Characterization Of Edible Cricket Peptides On Hypertensive And Glycemic In Vitro Inhibition And Their Anti-Inflammatory Activity On Raw 264.7 Macrophage Cells, Felicia Hall, Lavanya Reddivari, Andrea M. Liceaga
Department of Food Science Faculty Publications
Recent studies continue to demonstrate the potential of edible insects as a protein base to obtain bioactive peptides applicable for functional food development. This study aimed at identifying antihypertensive, anti-glycemic, and anti-inflammatory peptides derived from the in vitro gastrointestinal digests of cricket protein hydrolysates. After sequential fractionation, the protein digest subfraction containing the lowest molecular weight (<0.5 kDa), hydrophobic (C18) and cationic peptides (IEX) was found responsible for the most bioactivity. The cationic peptide fraction significantly reduced (p < 0.05) α-amylase, α-glucosidase, and angiotensin converting enzyme (ACE) activity in vitro, and also inhibited the expression of NF-κB in RAW 264.7 macrophage cells. A total of 28 peptides were identified with mass spectrometry (LC–MS/MS) and de novo sequencing from the potent fraction. Three novel peptides YKPRP, PHGAP, and VGPPQ were chosen for the molecular docking studies. PHGAP and VGPPQ exhibited a higher degree of non-covalent interactions with the enzyme active site residues and binding energies comparable to captopril. Results from this study demonstrate the bioactive potential of edible cricket peptides, especially as ACE inhibitors.

Refining Process And Quality Control Of Sunflower Oil, Etrit Beshtica, Luljeta Ajdini, Mentor Arifi, Lenda Ramadani, Donjeta Halimi
UBT International Conference
The quality control of edible sunflower oil is monitored through several stages, from unrefined oil, during the whole refining process as well as the bottled oil. Initially is checked the unrefined oil by means of analyzing its origin, enabling us to understand what the origin of the oil is. Subsequently are checked the compounds that need to be removed from the sunflower oil in the refining process. We also pay special attention to the preservation of some compounds present in the unrefined oil. The methodologies applied for oil quality control are physical- chemical and microbiological methods.
