Polyunsaturated fatty acid, volatile and sensory profiles of beef from steers fed citrus pulp or grape pomace.

The present study compared the effects of feeding dried grape pomace (DGP) or citrus pulp (DCP) at 150 g/kg dry matter compared to a control diet on major polyunsaturated fatty acids (PUFA), volatile and sensory profiles of beef. Feeding DGP or DCP diets to Angus steers for 90 d increased the proportions of C18:2n-6, C20:4n-6, C18:3n-3, total conjugated linoleic acid (CLA), n-3 and n-6 PUFA in muscle. Control-fed beef had greater concentrations of C18:1n-9, total aldehydes, ketones, and alcohols compared to DCP and DGP.

Meat quality, fatty acid profile, and sensory attributes of spent laying hens fed expeller press canola meal or a conventional diet.

This study evaluated the effects of feeding an expeller press canola meal (EPCM) supplement (20%) on the carcass, meat, and sensory quality characteristics of spent laying hens. Thirty EPCM-based and thirty conventionally (soybean based) fed Lohmann Brown-Elite spent laying hens were obtained from a commercial egg farm. Carcass, portions, physical quality, proximate composition, fatty acids, and sensory quality were determined.

Sensory quality and fatty acid content of springbok (Antidorcas marsupialis) meat: influence of farm location and sex.

Background: Springbok are harvested for meat production irrespective of farm location or sex from which the meat is derived. The present study investigated the influence of farm location (three farms containing different vegetation types) and sex on the sensory quality of springbok longissimus thoracis et lumborum muscle. The sensory profile (aroma, flavour and texture) was determined by descriptive sensory analysis, in addition to determination of the physical meat quality, proximate and fatty acid composition.

Impact of season on the chemical composition of male and female blesbok (Damaliscus pygargus phillipsi) muscles.

Background: The harvesting and consumption of game meat in South Africa is not limited to season. The study was thus aimed at investigating the seasonal impact on the chemical composition (moisture, protein, fat and ash contents) of male and female blesbok muscles (N = 32; longissimus dorsi, biceps femoris, semimembranosus, semitendinosus, infraspinatus and supraspinatus).

Results: A significant interaction (P ≤ 0.
