Abstract: Raw almonds are a major commodity, yet much is unknown about how storage conditions determine their shelf life. The storage stability, as measured by consumer assessments and chemical measures, of raw almonds was determined for samples stored in cardboard boxes and polypropylene packaging for 2 years at 4, 15, 25, and 35 °C, and at 50% and 65% relative humidity (RH). Samples stored in unlined cartons always failed (>25% rejection) before their counterparts stored in polypropylene bags under identical environmental conditions. Models determined that polypropylene packaging (as opposed to unlined cardboard cartons) extended the time until sample rejection …

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 …

It is a question in the field of food-safety that whether foreign genetically modified genes would transfer from the genetically modified cottonseed hulls to edible fungi. In this study, 15 Tremella fuciformis samples and 10 Pleurotus ostreatus samples (the cultivation media contained 75% and 92% genetically modified cottonseed hulls, respectively) collected from cultivation meida were evaluated by PCR to confirm whether the foreign genetically modified genes, CaMV 35S, NOS, CpTⅠ, Cry IA(c), were present. In addition, 47 samples which were probably grown in the media containing cottonseed hulls, were collected from the large and medium-sized supermarkets and farm produce markets. …

Food and Machinery
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. Moreover, it could be predicted that the pork quality could …

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) …
