Production and evaluation of tigernut (Cyperus esculentus)milk flavoured with moringa oleifera leaf extract

Abstract

Recently, research focus is on phyto - plants with their health benefits. This study therefore was carried out to produce and evaluate quality and acceptability of tigernut milk flavoured with Moringa oleifera leaf extract. Milk was prepared from tigernut and blended with Moringa extract in ratios 95: 5, 90: 10 and 85: 15 respectively while 100 % tigernut milk was used as control. Samples were coded as NOD, MDA, JNJ and ABD respectively. Proximate composition, emulsification, total titratable acidity (TTA), pH and sensory analysis were carried out on the samples. Results showed that sample JNJ had the highest percentages of carbohydrate and protein of 4.33 + 0.02% and 2.34 + 0.02% respectively, ABD had the highest percentages of lipid, ash and emulsifying property of 2.54 + 0.02%, 0.028 + 0.01% and 444 + 4.24 mg/100g respectively. The pH of all samples varies between 7.13 and 7.24. Sensory evaluation showed that sample NOD was the most acceptable. Most of the parameters measured are significantly different (p < 0.05).This study concluded that sample NOD could be produced for consumption and will be acceptable by the consumers. The higher the amount of Moringa oleifera leaf extract added to the imitation milk the better the health benefit it offers. This is because sample JNJ (85: 15 tigernut - moring) has the highest amount of protein and minerals when assessed).
