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 …

To enrich the variety of tallow products and reduce its melting point and hardness, the melting point and fatty acid composition properties of tallow, rapeseed oil, soybean oil, olive oil and cooking oil were analyzed. With the binary compatibilities of tallow and other four kinds of plant oil, their compatibility was studied through isothermal curve (SFC-T) and deviation curve (△SFC-T). The results suggested that four kinds of binary compatibilities mainly showed partial crystal phenomenon at different temperatures. The linear relationship of isothermal curve was good at 0～40 ℃ centigrade of each group(R2＞0.95). Among the four plant oils, rapeseed …

To investigate the feasibility of testing pork quality by terahertz (THz) spectroscopy nondestructively, refractive indexes and extinction coefficients of fat, muscle and skin of porcine tissue were collected by attenuated total reflection (ATR) mode in the range of 0.2～2.0 THz. The results showed that THz spectra of these tissues were different obviously in 0.2～1.6 THz. Water content was found to be a main factor affecting THz absorption of fresh tissues. The optical characteristic difference in THz band of different tissues could be utilized to identify tissue types rapidly and nondestructively.

The Legal Regulation On The Use Of Non-Gm(O) Label On Food, Liu Xuxia, Wang Qi
Food and Machinery
Non-GM(O) label is widely used on food in our country. The existence of information asymmetry increase the risk of misuse of non-GM(O) label,while the market mechanism itself can not regulate the misuse. In China,the legislation regulating the non-GM(O) label is not specific, thus misuse of non-GM(O) label was generally not considered to be illegal in judicial decision. Existing research mainly focuses on non-GM(O ) advertising instead of non-GM(O) label. By contrast, there are specific legislation which restrict the scope of food on which the non-GM(O) label can be used in Germany, Japan and the United States. The use of Non-GM(O) …

The ethanol content of beverages was measured by two methods, the static headspace gas chromatography and the traditional method of gas chromatography after distillation, using TG-WAXMS chromatographic column. The two methods had good linear relationship in the volume fraction of ethanol ranging from 0.01% to 5.00%. In traditional distillation method, the detection limit of volume fraction of ethanol was 0.003%, and the detection limit of static headspace was 0.001%. The results showed that due to the complicated pre-treatment processes, the recovery rate of the gas chromatography after traditional distillation was relatively low (83%~91%). While the method of direct determination of …

At present, the main algorithm used in feature extraction of apple is the traditional Hough algorithm. The algorithm has the disadvantages of complicated operation and poor real-time performance. In view of this situation, a new algorithm of apple fruit feature extraction is proposed in this paper. A sliding Gaussian template and apple image are convoluted to extract apple circles in this algorithm. Experiments and simulation results show that this method can achieve high accuracy of apple fruit detection under single, adjacent and overlapping conditions. In the case of a single apple, the detec-tion accuracy of apple fruit can reach 96.6%. …
