The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: A high performance liquid chromatography (HPLC) procedure using a LiChrosorb-NH₂ column and a eluant buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH 5.95, was developed for the successful separation and determination of ascorbic and erythorbic acids in selected food samples. Application of the method, which is sensitive, rapid and...

Immunomodulatory Actions of Bovine Whey Protein Isolates, Glycomacropeptide, and Their Digests: Insights from Macrophage and Human Studies

Creator:: Olsen, Wyatt
Abstract:: Whey protein isolate (WPI) and glycomacropeptide (GMP) have shown potential immunomodulatory properties. In this study, we investigated their effects on pro-inflammatory cytokine secretion using both in vitro and in vivo models. In LPS-stimulated THP-1-derived macrophages, digested WPI and GMP reduced cytokine expression, while whole GMP increased secretion. The in human...

Anti-inflammatory and Antioxidant Potential of Alaska Pollock Milt and Roe Hydrolysates

Creator:: Kemp, David C.
Abstract:: Ample research has demonstrated the largely untapped potential of bioactive peptides (BAPs) for treating systematic chronic inflammation (SCI). Protein hydrolysates are the mixture of peptides resulting from the hydrolytic breakdown of a protein. Numerous hydrolysates contain BAPs and exert beneficial effects in both in vitro and in vivo models. In...

Bovine Kappa-Casein Glycomacropeptide: Its Effects on the Microbiome, Inflammation and the Potential in Irritable Bowel Syndrome Management

Creator:: Qu, Yunyao
Abstract:: Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder experienced by 10–15% of the global population, manifesting as chronic abdominal pain, bloating and inconsistent bowel habits. The search for effective treatments remains ongoing. One promising contender in this realm is kappa-casein glycomacropeptide (GMP), a milk-derived peptide. Its potential benefits stem...

Effects of Whey Protein Isolate on the Human Gut Microbiota and Intestinal Function in Older Adults

Creator:: Rackerby, Bryna
Abstract:: Whey protein is a functional food comprised of numerous bioactive peptides and proteins, including glycomacropeptide (GMP), a hydrophilic casein peptide that separates with the whey fraction during cheesemaking. GMP has a unique amino acid composition, making it a viable nutritional therapy in disorders where certain amino acids are implicated, while...

Gel electrophoretic analysis of the protein changes in ground beef stored at 2⁰C

Creator:: Xiong, Youling
Abstract:: A study was completed to determine the extent of the protein changes occurring in ground beef stored at 2°C for 10 days. Sections of semitendinosus muscle were obtained immediately after the slaughter of three beef animals. Each section was divided into two equal portions, one of which was ground and...

Identification of Bitter Peptides in Aged Cheddar Cheese

Creator:: Kuhfeld, Russell
Abstract:: Bitterness is a common flavor attribute of aged cheese, but excessive levels are a flaw leading to consumer rejection. Bitterness in cheese has been primarily associated with milk casein-derived peptides of medium size (500–3,000 Da) and relative hydrophobicity. Herein, we demonstrate a novel approach for the identification of bitter peptides...

Analysis of Intact Glycomacropeptide Derived from Bovine Kappa-casein in Whey Protein Isolate and Intestinal Digesta

Creator:: Qu, Yunyao
Abstract:: Kappa-casein glycomacropeptide (CMP), a 64-amino-acid peptide, is released from kappa-casein after rennet treatment and is one of the major peptides in whey protein isolate (WPI). CMP has anti-inflammatory and antibacterial activities. CMP has two major amino acid sequences with different modifications including glycosylation, phosphorylation and oxidation. However, no previous work...

Effects of Whey Protein Consumption on Inflammatory Biomarker Levels in Healthy Older Adults

Creator:: Adler, Samuel
Abstract:: Whey protein’s potential for bioactivity is well documented, but there is disagreement on the extent to which it may modulate the immune system towards decreased inflammation. Decreased inflammation is generally perceived as a beneficial bioactivity in foods as excessive chronic inflammation is linked to morbidity and mortality. This thesis first...

Effects of temperature and holding time during pre-blanch on pH, pectic substances and quality characteristics of canned green beans

Creator:: Boni, Magloire C.
Abstract:: Physical, chemical and sensory attributes were examined on canned green beans (Oregon 1604) of sieve sizes 3 & 4 and 5 & 6 after one and three months of storage at room temperature (RT). The green beans subjected to different pre-blanch conditions in water (T1t1: 160°F - 30 min.; T1t2:...
