Study Of Rheological, Chemical, And Microbiological Properties Of Chami, A Traditional Emirati Soft Chees, Aysha Othman Abdullah Al Katheeri Apr 2018

Study Of Rheological, Chemical, And Microbiological Properties Of Chami, A Traditional Emirati Soft Chees, Aysha Othman Abdullah Al Katheeri

Theses

In this work, ten Emirati Chami cheese samples were collected and analyzed to determine their chemical composition, texture, rheology, and microbiological properties. Chami cheeses showed large variations in moisture (60.9–84.1%), protein (7.5–14.6%), fat (0.5–7.8%), and ash (3.4–8.0%) contents as well as in pH (3.6–4.4), and water activity (0.977–0.999%). The variation in fat content of samples suggested that extra fat was added; this added fat was either butter or vegetable oil as indicated by the fatty acid composition. The different samples showed peaks ...


Bill Owens: A Us Craft Beer Pioneer, 1982-2001, Patrick Walls May 2017

Bill Owens: A Us Craft Beer Pioneer, 1982-2001, Patrick Walls

Theses

Bill Owens is a pioneer in the United States craft brewing industry through his efforts as an advocate, writer, publisher, brewer, and entrepreneur who created a lasting legacy by influencing generations of brewers and beer fans. Owens wrote the first book on homebrewing equipment (How to Build a Small Brewery: Draft Beer in Ten Days in 1982). He opened the third brewpub in the country (Buffalo Bill's Brewery in Hayward, California in 1983) where, in 1985, he introduced the first commercial pumpkin beer among other beer style firsts. Owens published numerous brewery-focused magazines that featured many illustrious beer writers ...

Theses

Sudan grass (Sorghum x drummondii) is commonly grown for the production of animal fodder in the UAE. Cyperus conglomeratus (locally termed 'Thenda') is a sedge native to the UAE, and one of the very few plants that colonize soils of shifting desert dunes. The native plant is grazed by camels, and may thus have a potential for animal feed production. While Sudan grass is a mycotrophic plant that normally lives in symbiosis with arbuscular mycorrhizal fungi for facilitation of nutrient uptake, C. conglomeratus is a non-host to these root symbionts. In the deseli sedges rhizosheaths comprising of dense coats of ...


Biofilm Production By Food-Transmitted Bacteria And Their Control By Selected Nanoparticles, Mariam Al Shamsi May 2015

Biofilm Production By Food-Transmitted Bacteria And Their Control By Selected Nanoparticles, Mariam Al Shamsi

Theses

Biofilm is a population of bacteria attached to any types of surfaces and impeded in a self-produced matrix of extracellular polymeric substances. Biofilm exhibit up to 1000 fold antibiotic increased resistance to a broad range of antimicrobial agents. Several food-transmitted microorganisms are capable of forming biofilms and considered as a major source of contamination, transmission and infection. In the last few decades, nanoparticles has gained a great attention for their potential applications as antimicrobial agents. The aim of this work was to assess the biofilm formation capacity of food-transmitted bacteria under various environmental conditions and to investigate the efficacy of ...


Studies On The Initial Stage Of Lipid Oxidation In Bulk Oils., Elizabeth Budilarto. Dec 2014

Studies On The Initial Stage Of Lipid Oxidation In Bulk Oils., Elizabeth Budilarto.

Theses

During the oxidation of bulk oils, oxidation products (i.e. peroxide values, conjugated dienes and thiobarbituric acid reactive substances) are formed gradually and increased sharply at the end of the induction period. Tocophero1s were consumed, some water was formed, and micelles increased in size during the induction period of vegetable oils oxidized in bulk. The evidence that the evolution of micellar size was in parallel with the end of induction period corroborates the recognition that micelles are the active site of oxidation. The interaction of α-tocophero1 and three synergists: ascorby1 palmitate, phosphatidy1choline and L-lysine were studied in cod liver oil ...
