ABSTRACT
(Sample 1), while fat ngcd between 6.66% Sampf 3)
to 28.04% conclusion, enrichment of Okpa with up to 30% breweries spent graiij
s gnillcantly improved protein, fiber, and mineral contents, enhanced growth
performance, and ibaintaincd acceptable 1 a major agro-industrial byproduct as
a nutritional quality of sustainable means traditional foods while promoting
waste valorization. I his study was designed to develop and evaluate the
nutritional properties of Okpa (Bambara groundnut pudding) enriched with
breweries spent grain (BSG) in van ing proportions. Four formulations were
produced: Sample 1 (80% Okpa Hour + 20% BSG), Sample 2 (7 •% Okpa Hour i 30%
BSG), Sample 3 (60% Okpa Hour + 40% BSG), and Sample 4 (100,%iOkpa four -
control), 'fhc samples were subjected to proximate, mineral, and sensory
evaluations. alongside feeding trials using Wistar rats to determine growth
performance and pro'cin (quality indices. Results showed that moisture content
ranged from 51.28% (Sample 1) to 60.27% {Sample 3), with Sample 3 exhibiting
the highest (p < 0.005), indicating higher water activity and lower storage
stability. Ash content ranged between 2.87% (Sample 2) and 3.17% (Sample 1) s
iggestwg a moderate mineral composition. Fiber content varied from 0.85%
(Sample 4) to 1.1 8% ranged from 6.13% (Sample 3) to 10.89% (Sample 2). Protein
content (Sample 4) and 7.85% (Sample 2), and carbohydrate content from 22.61 %
(Sample 1). Vitamin composition revealed that Vitamin A ranged from 62+66 pg/
100 g (Sample 3) to 810.98 pg/100 g (Sample 2), Folate (B>>) from 9.37
mg/100 g (Sample I) to 1 8.57 mg/100 g (Sample 4), and Vitamin C from 26.75
mg/100 g (Sample 1) to 49.59 mg/100 g (Sample 3). Mineral analysis showed
magnesium values between 23.57 mg/100 g (Sample 4) and 60.36 mg/100 g (Sample
1). iron between 0.91 mg/100 g (Sample 2) and 1.67 mg/100 g (Sample 1). and
zinc between 0.98 mg/100 g (Sample 1) and 1.49 mg/100 g (Samplcj3). Sensory
evaluation revealed that Sample 1 consistently received the highest scores for
appcar'ani-c (8.40), taste (8.35), aroma (8.50), texture (8.30), and general
acceptability (8.25), all signi ficaiS11) different (p < 0.005) from other
samples. In contrast. Sample 3 (60% Okpa : 40% BSG) scored lowest across most
sensory attributes, indicating a negative effect of excessive BSG inclusion on
product appeal. In gnificantly improved sensory quality. This study therefore
highlights the potential of utilizing brcwcricS spent grain
