The major component of tomato processing industry wastes is seed. Samples of tomato (Petomech var.) pomace from industries of São Paulo state submitted to Hot and Cold Break treatments, were spontaneously fermented and washed to separate seeds. The oils were analysed for specific gravity, iodine and saponifícation numbers, refractive index, viscosity and fatty acid composition. Except for saponifícation number, Hot and Cold Break seed oils were very similar. In both treatments palmitic acid was the major saturated fatty acid, followed by stearic acid. Linoleic acid was the major unsaturated fatty acid followed by oleic acid. Both oleic and linoleic acids added up to over 60% of total fatty acids, being higher in Cold Break seed oils. Both treatments produced high nutritional oil quality. Differences in colour and viscosity may incur in more intense refining operations for Brazilian tomato processing industries due to the adoption of the Hot Break treatment.

Intensive Production

Dairy sheep farming is a vital sector of the agricultural economy in Greece. Information on the effect of the farming system on sheep milk characteristics is critical for producing dairy products with improved nutritional value according to the current guidelines for healthy food consumption. This study aimed to investigate the basic composition, physicochemical characteristics, fatty acid composition, and nutritional indices of milk produced in intensive and semi-intensive sheep farms. Bulk tank milk samples from 20 intensive and 20 semi-intensive sheep farms were examined. Sheep in the intensive farms were kept indoors and were fed with roughage, silage, and concentrates. Sheep in the semi-intensive farms were kept indoors during the night and were moved to the pastures during the day. Sheep were fed with roughage, silage, and concentrates in combination with grazing. Milk composition and somatic cell count were determined with automatic analyzers. The physicochemical characteristics were determined with standard laboratory methods. The fatty acid composition was analyzed by gas chromatography. The farming system did not affect milk chemical composition and physicochemical characteristics. However, milk fatty acid composition and nutritional value were significantly improved in milk from farms using the semi-intensive production system, and this favorable effect was attributed to the inclusion of pasture in sheep diet.
