Antioxidants and antioxidant enzymes status of rats fed on n-3 PUFA rich Garden cress (Lepidium Sativum L) seed oil and its blended oils.

Garden cress (Lepidium sativum L) seed oil (GCO) is a rich source of α-linolenic acid (ALA, 33.6 %) and the oil has a fairly balanced SFA, MUFA and PUFA ratio. In this study we have investigated the effect of GCO and its blends with n-6 PUFA rich edible vegetable oils sunflower oil (SFO), rice bran oil (RBO) and sesame oil (SESO) on antioxidant status of oils and antioxidative enzymes in Wistar rats.

Plastic fats from sal, mango and palm oil by lipase catalyzed interesterification.

Speciality plastic fats with no trans fatty acids suitable for use in bakery and as vanaspati substitute were prepared by interesterification of blends of palm stearin (PSt) with sal and mango fats using Lipozyme TLIM lipase as catalyst. The blends containing PSt/sal or PSt/mango showed short melting range and hence are not suitable as bakery shortenings. Lipase catalysed interesterification extended the plasticity or melting range of all the blends.
