Journal of Food and Drug Analysis
We have demonstrated that red algae Gelidium amansii (GA) hot-water extract (GHE) is a polysaccharide-rich fraction, containing 68.54% water-soluble indigestible carbohydrate polymers; the molecular weight of major polysaccharide is 892. Here, we investigated the mechanisms of GHE on plasma and hepatic lipid metabolisms in high-fat (HF) diet-fed rats. Rats were divided into: normal diet group, HF-diet group, HF-diet+5% GHE group, and HF-diet+1% cholestyramine (positive control) group. GHE supplementation for 8 weeks significantly decreased plasma cholesterol, LDL-C, and VLDL-C levels and increased the fecal triglyceride and bile acid excretion in HF diet-fed rats. GHE group has lower lipid contents in the …

Suitability Of Sugar Alcohols As Antidiabetic Supplements: A Review, Nontokozo Z. Msomi, Ochuko L. Erukainure, Md. Shahidul Islam
Journal of Food and Drug Analysis
The major goals in the management of diabetes are to maintain normal control of glucose metabolism and glycemia. Dietary modification is one of the most recommended treatment modalities for diabetic patients. The use of foods sweetened with sugar alcohols (also known as polyols) such as xylitol, sorbitol, mannitol, maltitol, lactitol, isomalt and erythritol, has brought an escalating interest. Since some sugar alcohols do not raise plasma glucose, as they are partially digested and metabolised. Diet composition and adequacy may be altered by replacing carbohydrates with sugar alcohols. It has been established that these polyols are appropriate sugar substitutes for a …

Towards New Strategies For Improving The Transfer Of Innovation Between University And The Food Industry, Gwilym A. Williams
Level 3
All commerce relies on effective strategies for completing a deal, but conducting the transaction at the university-industry interface with an intangible asset represented by research results remains a difficult proposition. Beyond differences of mission and culture, it is usually assumed that the established language of technology transfer can permit productive communication by a university across a wide diversity of industries. However, the experience of the authors indicates that an appreciation of aspects such as subtleties of language, conflicting goals, and market understanding must also be brought to bear in successfully completing a transaction. Information asymmetry remains a key challenge to …

Fruits and vegetables are high in nutrients that are essential for a healthy lifestyle. However, they also harbor an extensive array of microorganisms such as bacteria, which can be beneficial, neutral, or pathogenic. Foodborne pathogens can contaminate produce at any stage from the farm to the consumer’s table. Appropriate washing techniques using sanitizers can reduce the risk of pathogen contamination. Issues related to maintaining concentration, efficacy, and other problems have been a challenge for the food industry and, when left unresolved, have led to different outbreaks of foodborne illnesses. In this study, the efficacy of a lytic bacteriophage cocktail was …

Ulcerative colitis (UC), a major form of inflammatory bowel disease (IBD), is on the rise worldwide. Approximately three million people suffer from IBD in the United States alone, but the current therapeutic options (e.g., corticosteroids) come with adverse side effects including reduced ability to fight infections. Thus, there is a critical need for developing effective, safe and evidence-based food products with anti-inflammatory activity. This study evaluated the antiinflammatory potential of purple-fleshed potato using a dextran sodium sulfate (DSS) murine model of colitis. Mice were randomly assigned to control (AIN-93G diet), P15 (15% purple-fleshed potato diet) and P25 (25% purple-fleshed potato …

Effective laboratory and classroom demonstration of microbiome size and shape, diversity, and ecological relationships is hampered by a lack of high-resolution, easy-to-use, readily accessible physical or digital models for use in teaching. Three-dimensional (3D) representations are, overall, more effective in communicating visuospatial information, allowing for a better understanding of concepts not directly observable with the unaided eye. Published morphology descriptions and microscopy images were used as the basis for designing 3D digital models, scaled at 20,000×, using computer-aided design software (CAD) and generating printed models of bacteria on mass-market 3D printers. Sixteen models are presented, including rod-shaped, spiral, flask-like, vibroid, …

The Effects Of Wort Oxygenation Scenarios On Fermentation Performance, Volatile Flavor Compound Development, And Flavor Stability In High Gravity Brewing, Ben Jabson
Master's Theses
High gravity (HG) brewing has become the most used strategy for maximizing fermenter productivity in commercial brewing. While HG brewing has many benefits, the additional stress placed on the yeast due to the higher concentration of fermentable sugars in the wort can negatively impact fermentation performance and flavor compound formation. A proper dissolved oxygen (DO) level is vital to guarantee adequate yeast performance during HG fermentations. Dissolved oxygen is vital to yeast viability throughout the fermentation process, as yeast requires oxygen to synthesize vital cell membrane components needed for continued anaerobic growth and cell division. Previous research has demonstrated the …

The fatty acid composition, volatile components, rheological properties and antioxidant activity of yak butter at different altitudes (2 500~2 800 m, 3 500~4 000 m and above 4 300 m) in Tibetan were analyzed and compared. The results showed that altitude had significant effects on fatty acid composition, volatile components, rheological properties, and antioxidant activity (P<0.05). The unsaturated fatty acid content of yak butter at altitude of 2 500~2 800 m was the highest. Yak butter with an altitude of more than 4 300 m had pure smell and best flavor quality. Yak butter at altitudes of 3 500~4 000 m had the best fluidity. Yak butter at different altitudes had different antioxidant abilities, among which yak butter at altitudes ranging from 2 500 m to 2 800 m had the strongest DPPH free radical (66.99 mmol/100 g Trolox), hydroxyl free Trolox (26.71 mmol/100 g Trolox), superoxide anion scavenging ability (22.85%), and iron ion chelating antioxidant ability (1.41%).
