Abstract

A blend from several plant materials' roots, tubers, grains, and legumes is known as swallow

composite flour. In this study, the dried composite flours (Composite A) and a regional blend

called "elubo" (Composite B) were compared for their nutritional value and microbiological

health. The maceration method was used to prepare the aqueous extract of Composite A and B,

and standard protocols were observed in all adopted analyses. The results showed that there were

significant differences (P<0.05) among the samples. Proximate analysis revealed higher values in

Composite A than in B, with high Protein (8.60±0.02%) and Crude fiber (13.73%), while CHO

(42.77±0.59 %) and moisture (4.32±0.05%) of Composite B are lesser. Phytochemical screening

showed high Flavonoids (41.97±0.39), Alkaloids (35.40±0.37), Tannin (30.10±0.32), phenol

(40.38±0.45) and cardiac glycoside (30.35±0.86), than Composite B, Saponin (26.15±0.75) and

Terpenoid (22.08±0.35) were low. DPPH, Nitric oxide and reducing power scavenging activity

(%Inhibition), in 25, 50, 75 and 100µg/ml increased in Composite A. Some minerals were present

except for the absence of Lead and Cadmium from Composite A. The total plate count of microbial

load activities for Composite B (147250) was high and Composite A (102000) low, amongst

Escherichia coli (110 and 200cfu/g), Staphylococcus aureus (180 and 350cfu/g) in 25 and 50

µg/ml concentration, yeast and mold were not detected in both samples. This packed flour formula

is naturally preserved, nutritious, has medicinal effects, and has lower microbiological activities

as compared to market Composite B and ICMSF (International Commission for Microbiological

Specification for Foods) criteria.
