Study of the probiotic properties of subsp NCIM 5752 and the optimization of whey-based media for the production of its biomass using response surface methodology.

Unlabelled: In this study, NCIM 5752, a new isolate has been explored for probiotic properties and has shown significant bile salt hydrolase activity and cholesterol-reducing activity (56.7 ± 0.27%) in the presence of bile salts.

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.

Physico-chemical characteristics of burfi prepared by using medium chain triglyceride rich margarines.

Medium chain triglyceride rich margarines were prepared using palm, coconut oil blends in the ratio of 80:20 (Margarine 1) and 60:40 (Margarine 2). The margarines were used to prepare burfi and compared with products prepared using commercial margarine, ghee and butter. The physicochemical characteristics such as texture, color, free fatty acid, peroxide value, saponification value, unsaponifiable matter and fatty acid composition of oils, fats and margarines were carried out.

A comparative study on starch digestibility, glycemic index and resistant starch of pigmented ('Njavara' and 'Jyothi') and a non-pigmented ('IR 64') rice varieties.

In vitro starch digestibility and glycemic indices of three rice varieties- 'Njavara', 'Jyothi' (pigmented rice verities) and 'IR 64' (non-pigmented rice) with similar amylose content were studied. Starch digestibility studies showed differences in glycemic response in three types of rice. The rate of starch hydrolysis was maximum (67.

Physicochemical and genetic analysis of an endemic rice variety, Njavara (Oryza sativa L.), in comparison to two popular South Indian cultivars, Jyothi (PTB 39) and IR 64.

Njavara is a medicinal rice strain, endemic to Kerala, South India, bestowed with medicinal qualities. Genetic variations and some of the physicochemical properties were studied using standard molecular protocols and compared with those of nonmedicinal rice varieties: Jyothi and IR 64. Njavara showed 11 unique positive and 36 unique negative markers to differentiate it from Jyothi and IR 64.
