The availability of hares (Lepus europaeus Pallas), unlike that of domestic rabbits, is restricted by hunting seasons. Rabbit meat, according to research from Spain, is a rich source of K, P, Fe and Mg, but poor in Na, being recommended for people with hypertension. The largest quantity of macro minerals studied in rabbit meat was determined for K and P, and the most abundant micro minerals were Zn, Fe, Cu and Mn. In hare meat, ash content is not sufficiently studied. The current low level of knowledge motivated the present study. The aim of this study was to establish the ash content for major muscle groups and edible offal of hares. The biological material used was collected from 49 hares with an average weight of 5.6 kg, at the age of reproductive maturity (adults: 11-12 months). Different muscle groups (the muscles Cervicalis, Intercostalis, Longissimus Dorsi, Psoas major, Triceps Brachi, Biceps femoris, Semimembranosus ) and the main edible offal (heart, liver, kidney) were sampled. The ash was determined by calcination (in Supertherm C311 oven calcination) at 550 0 C. The results obtained were interpreted statistically (arithmetic mean (X), standard deviation (s), variance (s 2 ) and coefficient of variation (V%) and the statistical significance of differences was tested using the ANOVA Single Factor algorithm (p>0.05; p<0.01; p<0.001).

Currently, mainly non-biodegradable petroleum-based synthetic polymers are used as packaging materials for foods, because of their availability, low cost and functionality. However, biopolymers can be made from renewable resources without the environmental issues of petroleum-based polymers and with the additional advantage of being available from renewable sources or as by-products or waste-products from the food and agriculture industries. The aim of this study was to test some food packaging biopolymers based on PVA. In this respect, some biopolymers for food packaging applications were subjected to biodegradation tests by covering the tested samples with soil. The samples were incubated in known temperature and humidity conditions. The experiment lasted 45 days, after that the samples were washed, weighed and the biodegradation degree was calculated. The obtained results shows that PVA is a promising material for food packaging usage, as it is made from renewable resources and it is environmentally friendly.

For this reason, Europeans are increasingly interested in discovering its benefits and how the chemical composition of horse milk differs from that of other species. This interest is reflected in the number of new farms selling mareâ€™s milk around the world as this milk is the most similar to human milk. Mareâ€™s milk is considered to be highly digestible, rich in essential nutrients and whey protein, which makes it very suitable as a substitute for bovine milk in paediatric diets. During the period of lactation, mammal's milk composition is subject to rapid changes in macro- and micro-elements, as well as in the quantity and quality of proteins, lipids and saccharides, being ideal food for infants. The primary use of mareâ€™s milk has been the rearing of foals, but recently, due to the similarity of its chemical composition to that of human milk, it has raised particular interest and some experiments have been done to apply it as a raw material for the preparation of special food products for human consumption. Mareâ€™s milk products are very common in Russia and Central Asia throughout Mongolia. In the 19 th century, some Russian scientists explored its therapeutic properties and then in 1859 they founded the first sanatorium where treatments with mareâ€™s milk could be made under medical control.
