Lepilemur leucopus was the subject of an 11-month field study at Beza Mahafaly Special Reserve, Madagascar. Radio-tracking provided point samples of activities and foods eaten for the 5 subjects (4 males, 1 female) across the hot, wet season and the cool, dry season. Across all seasons and animals, about 50% of the time was spent resting and/or self-grooming and about 30% of the time feeding. T...
With the increase in consumer awareness, demand for minimally processed foods and ecofriendliness, various technologies were developed for food processing and preservation. The conventional thermal food preservation and processing techniques appears to have the shortcoming of adversely affecting the food quality, organoleptic properties and nutrients. However, many non-thermal food preservation...
BACKGROUND AND AIM Once thought to be uncommon in Asia, coeliac disease (CD) is now being increasingly recognized in Asia–Pacific region. In many Asian nations, CD is still considered to be either nonexistent or very rare. In recognition of such heterogeneity of knowledge and awareness, the World Gastroenterology Organization and the Asian Pacific Association of Gastroenterology commissioned a ...
In the United States, bioengineered grains are prevalent in the food supply, but bioengineering remains poorly understood by the public (Hallman, Hebden, Aquino, Cuite, & Lang, 2003). Scientists and other experts with a stake in food technology have often suggested that public fears about bioengineering would be overcome if members of the public were given more information (Brady & Brady, 2003;...
The condition dependence of sexually selected traits is an important assumption of sexual selection theory. Several laboratory studies have documented a positive relationship between food availability, body condition, and sexual display. However, these studies might not reflect the resource allocation between body maintenance, reserves, and the sexually selected trait under natural conditions. ...
Introduction: Observance of food hygiene and safety by the staff working in the food supply and distribution sector is one of the most important factors in prevention of foodborne diseases. However, considering the inadequate knowledge and inappropriate performance of the staff, we are faced with many epidemics of food poisoning. Therefore, this study was conducted to determine the knowledge, a...
While urban expansion increasingly encroaches on natural habitats, many wildlife species capitalize on anthropogenic food resources, which have the potential to both positively and negatively influence their responses to infection. Here we examine how food availability and key nutrients have been reported to shape innate and adaptive immunity in wildlife by drawing from field-based studies, as ...
دسته ای از ترکیبات شیمیائی که مخصوصا با گسترش زندگانی جدید (ماشینی)اهمیت فرآینده ای پیدامی کنند، افزودنیهای مختلف غذائی میباشند که در صنایع مربوطه بکار گرفته می شوند بکارگیری بخشی از این موا تحت عنوان طعم دهنده ها بمنظور تامین طعم و مزه طبیعی درفرآورده های صنعتی تقریبا اجتناب ناپذیر گشته و همگام با توسعه تولیدات روبه توسعه می رود. یک شناخت سیستماتیک و جامع از خواص و آثار اینگونه مواد طبیعتا مست...
