ABSTRACT
The research was carried out to
find out the vitamin and mineral content of avocado and peanut spread blend.
The avocado fruits were kept at room temperature for three days to complete the
ripening process. The fruits were washed with clean water, peeled, deseeded and
cut into four smaller pieces to aid blending. These small pieces were finally
pulverized using a domestic food blender at speed 4. The peanuts were sorted,
washed, thereafter, they were transferred to a large plastic colander and
salted evenly. After leaving to stand for a few minutes to hasten the water
drainage, the peanuts were laid out flat on top a sack under direct sunlight
for 30 minutes, then split into two batches. The first batch were spread out
thinly in a flat aluminum tray and placed in the gas oven for an hour at 80⁰C,
during which the peanuts were stirred intermittently to aid uniform roasting
and flavor development. The second batch of peanuts were toasted at low heat,
using a large frying pan, fan, and heat carrier (raw garri). After roasting,
peanuts were left out to cool, peeled off the skin before blending (using
Binastone dry grinder BLG-412) at a steady, controlled speed, until paste was
formed. This was immediately packaged in an air-tight plastic jar and labelled.
The Peanut and Avocado pastes were respectively mixed in the following ratios,
i.e., Peanut: Avocado 80:20, 70:30, 60:40,50:50 and 100:0 as control. The
samples were coded as SPAZ3 (80:20), SPAZ1 (70:30), SPAZ4 (60:40), SPAZ2
(50:50), SPAZ5 (100:00). The samples were analyzed for their vitamin and
mineral content using AOAC (2016) methods. The data generated were
statistically analysed by one way analysis of variance (ANOVA) and significant
differences detected using Duncan multiple range test at 95% confidence level
(p<0.05). The result of the vitamin analysis showed that vitamin A content
of SPAZ4 (9.51mg) was higher than other samples with a significant difference
(P<0.05) and was least in sample SPAZ3 (4.27mg), vitamin A was not dictated
in SPAZ5 (0.00). Vitamin E contents was highest in sample SPAZ3 (3.56mg) and
was least in sample SPAZ2 (2.41mg). Vitamin B1 contents was highest
in sample SPAZ5 (0.61mg) and least in sample SPAZ3 (0.19mg) with a significant
difference (P<0.05). Vitamin B2 was highest in sample SPAZ4
(2.12mg)and least in sample SPAZ5 (0.04mg). The result of the mineral content
revealed that calcium, potassium, magnesium, and iron was highest in sample
SPAZ5 (87.54mg, 149.16mg, 106.67mg, 2.77mg) respectively and was least in
sample SPAZ3 (23.51mg) for calcium, sample SPAZ2 (35.55mg, 15.36mg, 0.26mg) for
potassium, magnesium and iron respectively. This research reveals that Avocado
enhances vitamin A content in spread blends. This blend offers a nutrient-dense
alternative to traditional peanut butters, making it a valuable option for
health-conscious consumers. This study conclusively demonstrated the
nutritional benefits of combining avocado and peanut in various proportions,
providing valuable insights for food manufacturers and consumers seeking
healthier spread options.
