RESUMEN
Protein malnutrition is a major concern in Bangladesh where there is a high dependence on cereal-based diets. Use of protein-calorie sources of plants like soybean and mushroom as a dietary supplement may provide a solution. This study was designed to formulate a high protein and fibre enriched soy-mushroom health drink powder, and to compare its nutritional contents with locally available health drink powders. Methods: Soy-mushroom health drink powder was developed mainly from soy flour, mushroom, germinated wheat flour, malt extract and milk powder. Three locally available health drink powders were randomly selected. Proximate and microbiological analyses and sensory evaluation were undertaken by standard methods. Data were analysed using Statistical Package for the Social Sciences (SPSS). Results: The moisture, ash, protein, fat, fibre, carbohydrate and energy contents of the developed soy-mushroom health drink powder ranged from 3.04-3.96%, 3.23-7.4%, 8.98-21.37%, 1.10-10.13%, 0.04%-1.50%, 59.93-81.58% and 363.54-416.40 kcal/100g, respectively. The soy-mushroom product had the highest content of protein, fibre, energy and the lowest content of carbohydrate compared to the other health drink powders. Based on sensory analysis, the soy-mushroom product showed high acceptability. Microbiological assessment showed the shelf life of this product to be one year. Conclusion: The soy-mushroom health drink powder was nutritionally superior to locally available health drink powders and could serve as a nutritional supplement.
RESUMEN
Objective: To determine the antihypercholesterolemic effects of kenaf seed samples and compare with the commercial hypocholesterolemic drug on serum lipids profiles and malondialdehyde (MDA) level in the rat. Methods: Kenaf seed oil (KSO), microencapsulated kenaf seed oil (MKSO), kenaf seed extract (KSE) and defatted kenaf seed meal (DKSM) were prepared and phytochemicals screening on these samples were done prior in vivo study. Phenolic compounds in KSE were quantified using high performance liquid chromatography. There were 40 (divided in eight diet groups of 5) male Sprague dawley rats adapted to normal standard diet or hypercholesterolemic diet (HD) with or without the treatment of these kenaf samples for 32 days. Results: All the kenaf samples exhibited to contain most of the major phytochemicals. KSE possessed gallic acid, tannic acid, catechin, benzaldehyde, benzoic acid, syringic acid, sinapic acid, ferulic acid, naringin acid, and protocatechuic acid. The significant higher (. P<0.05) serum total cholesterol, low density lipoprotein cholesterol and MDA levels in HD group without treatment than the normal control group suggested the hypercholesterolemia was induced by the incorporation of cholesterol into diet. KSE exhibited higher cholesterol-lowering properties due to the significant lower (. P<0.05) in serum triglycerides, total cholesterol and MDA levels. KSE showed the highest efficiency of cholesterol-lowering activity, followed by KSO, MKSO and DKSM. Conclusions: DKSM, MKSO, KSO and KSE appeared to have comparable anti-hypercholesterolemic effect with the commercial hypocholesterolemic drug. Hence, kenaf seed could be used as an alternative natural source to replace the synthetic hypocholesterolemic drugs.
