Stable isotope profile (C, N, O, S) of Irish raw milk: Baseline data for authentication
نویسندگان
چکیده
Grass-based milk production is a major contributor to Irish agricultural output. The study characterized the pool using stable isotope ratio analysis of carbon, nitrogen, oxygen and sulphur. Authentic raw samples were collected from 50 farms on five occasions over 13 months. Mean values −27.11, 6.79, −3.27 6.16‰ obtained for δ13C, δ15N, δ18O δ34S, respectively. δ13C reflected high level grass input increased with increasing cereal concentrate feed (P < 0.001). most negative in spring. There was significant interaction between season δ15N 0.05), impact feeding evident δ34S lowest at highest 0.05). isotopic reported here describe may offer potential discriminate dairy products similar commodities other countries.

Rasht Abad Cu±Au deposit is a part of the Tarom-Hashtjin metallogenic belt in the western Alborz-Azerbaijan zone. The exposed units in the area include volcanic, sub-volcanic calc-alkaline to shoshonitic rocks with Upper Eocene age and belongs to magmatic arcs setting. The most important alterations related to mineralization include low temperature silicification and sericitic alterations. Mine...
