UBT International Conference

Biological systems are very complex regarding their kinetic behavior. There are many models that intend to predict fermentation performance, although Monod equation remains the best model. A detailed investigation of batch fermentation process at room temperature for two different types of yeast Sacharomyces carlsbegensis and Saccharomyces cerevisiae was carried out. Batch fermentation experiments were carried in 1 liter bioreactors, in the same medium, time and fermentation conditions. Kinetic constants were used to compare fermentation performance under similar conditions. Kinetic parameters investigation was done based on growth kinetics, ethanol productivity and substrate consumption (glucose) using computer simulation for different kinetic models. …

Optimization Of The Ground For Cab 6p (Prunus Cerasus), Avdirrahman Gashi, Sami Gashi, Taulant Mitrushi, Edlira Kukali

UBT International Conference

Rooting is a process that is induced by many difficulties, especially in fruit trees. For this reason, four nutrient terrains that contain different concentrations of auxin ANA (α-naphthaleneacetic acid), BAP, GA3 and macro and micronutrient MSs are compared. Rizogenesis is observed after three to four weeks of cultivation on the ground of rupture. Explants react differently in each field used (Figures 4,5,6,7). The concentration of inorganic and auxinous ANA salts on the nutrient terrains affects the rooting index and the characteristics of the roots. Plants of the prunus cerasium L species showed better results during rooting cultivation I, where the …

UBT International Conference

Proteases are group of enzymes that catalyze the hydrolysis of proteins, resulting in peptide and amino acid production. These are considered as commercially most significant among industrial enzymes, consisting about 60% of the total enzyme market. Proteases have wide areas of application in several industries like food, detergent, textile, pulp and paper, and pharmaceutical industries, as these offer environmentally benign, sustainable solutions to several challenges in the corresponding industry.Enzymes can be produced by plants, animals or microorganisms, yet the majority is produced by (recombinant) microorganisms, typically with modified features for high enzyme production. However, for e.g. food industry, the use …

In the second phase of the study, density and dynamic viscosity were experimentally determined as a function of temperature from 5 to 40°C. Kinematic viscosity and fluidity were determined according to the definitions. The …

Interaction Of Nanofibers With Epithelial Cells In The Digestive System, Agron Millaku

UBT International Conference

In this study, we provide the evidence of interaction of tungsten nanofibres (NF- WOx) with epithelial cells in the digestive tube of a test organism, woodlouse Porcellio Scaber studied by scanning electron microscopy (SEM). When the nanofibers enter the body through food, not all of them pass through the digestive system, without an interaction with the epithelial cells. The result has provided us that in some areas nanofibers can react with epithelial cells on the digestive tube very fast. The images which were taken in the treated samples through scanning electron microscopy and energy dispersive spectroscopy analysis clearly show such …

Food Science Faculty Articles and Research

Sharks are harvested globally and sold in a variety of commercial products. However, they are particularly vulnerable to overfishing and many species are considered protected or endangered. The objective of this study was to identify species in various commercial shark products and to assess the effectiveness of three different DNA barcoding primer sets. Thirty-five products were collected for this study, including fillets, jerky, soup, and cartilage pills. DNA barcoding of these products was undertaken using two full-length primer sets and one mini-barcode primer set within the cytochrome c oxidase subunit (COI) gene. Successfully sequenced samples were then analyzed and identified …

Department of Food Science and Technology: Faculty Publications

Aging populations experience a decline in adaptive immune system function also known as immunosenesence. Protein nutrition has been shown to stimulate and strengthen the immune system, and such approaches are needed for this growing segment of the population. A controlled, randomized, double blind pilot study was conducted to compare two different protein sources (soy and dairy) as nutritional supplementation to enhance vaccine response. Our objective was to examine the immune stimulating effects of dairy protein subjected to ultraviolet radiation (UV-C) radiation treatment process instead of pasteurization. Participants were 21 healthy individuals over 60 years of age who consumed 6 g …

Acidulant Effect On Greening, Reducing Capacity, And Tryptophan Fluorescence Of Sunflower Butter Cookie Dough During Refrigerated Storage, Joele Tsopkeng Atonfack, Zeynep Akyol Ataman, Lilian M. Were

Food Science Faculty Articles and Research

BACKGROUND: Sunflower seed derived butter can be a source of protein and phenolic antioxidants in refrigerated dough. Chlorogenic quinone-amino acid induced greening can however occur at alkaline pH, which could result in less bioavailable conjugated phenol-amino acids. Acidulants were tested as potential anti-greening ingredients in refrigerated chemically leavened cookie dough. Effect of refrigerated storage time, leavening agents and acidulants on tryptophan fluorescence (»ex=280nm, »em=300-500), color (hunter LAB), reducing capacity (DPPH and Folin-Ciocalteu reagent reducing capacity/FCRC), and hydroxycinnamic acids were measured.

RESULTS: The pH range of acidified doughs was 4.83–6.98 compared to 7.65- 9.18 in nonacidified leavened doughs after 24 days. …
