Processing of a Nutrient-Rich Cereal Butter an Alternative to Peanut Butter

Abstract

Cereal butter were made from sunflower, pumpkin, garden cress, corn, rye and peanut butter served as control. Chemical, physical, microbiological, textural and sensory evaluation of cereal based butter poduced from different types of cereal were analzed using a standard method. Pumpkin had highest protein (30.23%), while sunflower, pumpkin and peanut cereals had the highest amounts of fats (51.46, 49.05 and 48.00%, respectively). Also, corn had the highest amounts (72.56%) of carbohydrate. For microbiological evaluation, data show that total mould count ranged between 1.10 to 1.80 log cfu/g for rye and peanut, respectively. Garden cress is a good source of potassium, calcium, iron, and sodium. Also, Pumpkin is a good source of Magnesium, zinc, Phosphor and Selenium.  Sunflower had the highest value of Vitamin B1, B2, B6, B9 and E but garden cress had the highest value of B2, K and C vitamins. The fatty acid composition of cereals reported that palmitic acid was the highest value in rye 21.80%. The Palmitoleic acid ranged from 0.22 to 12.50%, the lowest was peanut and highest occurred in sunflower. The highest of oleic acid was peanut 46.80%.  Sunflower had highest Linoleic acid (69.0%) and garden cress had highest of linolenic acid 32.18%. Rye had highest value (20.69%) in Arachidic acid and garden cress scored highest in Eicosenoic acid (13.40%). The microbiological quality of cereals butter samples are total aerobic bacterial counts (TAB) ranged between 1.09 log cfu/g (rye butter) to 1.91 log cfu/g (peanut butter). Garden cress was obtained the higher for viscosity value (16100, 15900 and 15700 cp/s) at 25, 40, 60°C than other cereals butter. In texture analysis, garden cress butter had the highest significant amounts of hardness, cohesiveness, gumminess, chewiness and adhesiveness. Sensory evaluation of sunflower butter had the highest significant amounts of overall acceptability, peanut butter then pumpkin butter (96.30, 88.40 and 79.20, respectively) in all samples. Results could be useful in improving cereal butter processing and delivering sunflower butter to consumers who are more concerned as a functional food, high fat content and peanut allergy.
