Characterization And Bioactive Properties Of Camel Whey Protein Hydrolysate Generated With Gastric And Pancreatic Proteases, Sabika Jafar Apr 2018

Characterization And Bioactive Properties Of Camel Whey Protein Hydrolysate Generated With Gastric And Pancreatic Proteases, Sabika Jafar

Food Science Theses

Camel milk has been used for its nutritional and therapeutic benefits since ancient times. Previously, whole camel milk and casein proteins have been explored for their potential bioactive properties. However, studies on camel milk whey proteins and their hydrolysates are still scarce. Hence, the aim of the proposed thesis was to evaluate camel whey proteins and their hydrolysates for potential bioactivities like antioxidant, antimicrobial, antidiabetic, antihypertensive, and anti-cholesterol properties. Production of the hydrolysates was carried out using three digestive enzymes – pepsin, trypsin and chymotrypsin for 3 and 6 h of hydrolysis time. Hydrolysates were characterized by degree of hydrolysis (DH ...


Effect Of Heat Treatment On Camel Milk Proteins, Crystal Dcosta Clement Apr 2018

Effect Of Heat Treatment On Camel Milk Proteins, Crystal Dcosta Clement

Food Science Theses

Camel milk is important in the dry and arid lands because of its cultural, nutritional, and therapeutic properties. Milk proteins are known to be affected by various treatments including heating. The structure of proteins are known to change upon exposure to temperatures due to unfolding/folding and intra- and inter-molecular interactions. The aim of this thesis was to study the effect of various heating temperatures (60-130 °C) and times (0, 1, 10, and 30 min) on camel milk proteins. Electrophoresis (SDS-PAGE), free thiol groups, and hydroxymethylfurfural were used to observe the changes in proteins after the heat treatments. It was ...


Physicochemical Characteristics Of Mono Floral Emirati Honey., Maryam Mohammed Alyammahi Apr 2018

Physicochemical Characteristics Of Mono Floral Emirati Honey., Maryam Mohammed Alyammahi

Food Science Theses

Honey is a sugar solution used as a food and as a food ingredient. According to Codex standards, honey from different floral sources is regulated by its content of sugar (>60 %), moisture (<20 %), acidity (<50 meq/kg), and hydroxymethylfurfural (<40 mg/kg) and (80 mg/kg) of honey of declared origin from countries or regions with tropical ambient temperatures. The aim of this thesis was to study the physicochemical composition of four types of monofloral honeys collected in UAE: sider (Ziziphus spina-christi), samar (Acacia tortilis), ghaf (Prosopis juliflora), and neem (Azadirachta indica). Twelve pure honey samples (5 sider, 5 samar, 1 ghaf, and 1 neem) were tested for their main physicochemical parameters including sugar composition, moisture content, pH/free acidity, minerals, total phenolic compounds, hydroxymethylfurfural, texture, viscosity, and glass transition temperature. Results of all samples were found to fall within the accepted levels in the Codex honey standards ...


Probiotic Characterization Of Lactic Acid Bacteria (Lab) Isolated From Dried Emirati Fish And The Health Promoting Benefits Of Fermented Fish Sausages By Selected Isolates, Nadya Salem Sultan Saeed Al Kalbani Apr 2018

Probiotic Characterization Of Lactic Acid Bacteria (Lab) Isolated From Dried Emirati Fish And The Health Promoting Benefits Of Fermented Fish Sausages By Selected Isolates, Nadya Salem Sultan Saeed Al Kalbani

Food Science Theses

Probiotics have great positive impacts on human health. Therefore, finding new probiotics possess novel probiotic characteristics would be greatly appreciated by medical, scientific and food industrial societies. This study aimed to isolate lactic acid bacteria (LAB) from traditionally dried fishes, assess their safety aspects, characterize their probiotic features, and investigate their potential health-promoting benefits of fish sausage fermented by selected LABs, in-vitro.

Out of one hundred and fifty (150) isolates, 85 isolates were considered as a potential probiotic. The 85 isolates achieved a reduction under gastric juicy ranged from 0.5-5.2 log10 CFU/mL during 2h of incubation and ...


Assessment Of Nutrition Knowledge And Dietary Behaviors Of Post Bariatric Surgery Patients Attending The Outpatient Clinic Of Rashid Hospital, Dubai, Souheir Mahmoud Alia Mar 2018

Assessment Of Nutrition Knowledge And Dietary Behaviors Of Post Bariatric Surgery Patients Attending The Outpatient Clinic Of Rashid Hospital, Dubai, Souheir Mahmoud Alia

Food Science Theses

Obesity is regarded as an increasingly prevalent public health problem, with enormous adverse health consequences. It also increases the risk for co-morbidities. There are several means to treat obesity, and bariatric surgery has emerged as one of the most prevalent ways to treat obesity. Despite the vast research assessing nutrition knowledge of patients regarding several health conditions, existing research assessing the nutrition knowledge of post-bariatric surgery patients is limited, although this category of patients is very susceptible to malnutrition post-surgery. The aim of this study was to assess the patients’ general nutrition knowledge and the knowledge specific to the dietary ...
