title: Assessment of transesterified palm olein and Moringa oleifera oil blends as vanaspati substitutes.
abstract: This study aimed to investigate the suitability of Moringa oleifera oil and palm olein blends as vanaspati substitutes on the basis of physico-chemical and sensory characteristics. Blends were prepared either by blending Moringa oleifera oil or palm olein at 25:75, 50:50, 75:25, and 100 ratios, transesterified by Rhizopus miehei, compared with market vanaspati, designated as T1, T2, T3, T4 and T5, respectively. The blends were filled in 3-layer polyethylene pouch packs, stored at ambient temperature, sampled at every at 0, 90 and 180-days for the assessment of storage stability. The melting point and iodine value of T2 and control were 36.8, 37.2 °C and 62.2, 51.8, with no effect on free fatty acids content, peroxide, anisidine values and color of the deodorized stuffs. C18:1 content of T2 was 59.7 % with no trans fatty acids. Trans fatty acid content of the market vanaspati was 22.9 %. The addition of Moringa oleifera oil improved the induction period of the blends strongly inhibited the formation of primary and secondary oxidation products. The overall acceptability score of French fries prepared in T2 was 81 % of the total score (9). Blend containing 50 % palm olein and 50 % Moringa oleifera oil can be used in the formulation of a functional shelf stable fat that can be used as a vanaspati substitute.
