Title : Extraction and characterization of polyphenols from nopal and its by products for food application
The mandate of current study was to compare the different extraction solvents for their extraction yield of prickly pear peel and fruit. Purposely, water, ethanol, and methanol were used by adopting conventional solvent extraction for comparison. The variables targeted for the extraction process in different modules were time (30, 60, 90 minutes), sample to solvent ratio (1:6), at fixed temperature (55?) with purposed solvent concentration , water 100%, ethanol and methanol to water ratio were (70%:30%) . The outcomes suggested that all the variables found to be momentously (P≤0.05) effecting the extraction rates. All the extracts were evaluated for their antioxidant activity through TPC, TF, FRAP, DPPH, β-carotene and ABTS assay estimation. Among the solvents, methanol performed more efficient followed by ethanol and water. Meanwhile, both prickly pear peel and fruit imparted good antioxidant activity, although, fruit elucidated better antioxidant as compare to peel. However, in the time intervals 90min executed better extraction trailed by 90 and 30min. In product development phase, four kinds of functional fudge were prepared from the prickly peel and fruit powder. The prepared functional fudge was probed for their physicochemical assay, storage behavior, and sensory properties. The outcomes elucidated momentous effect on color, pH, Water activity and acid value with treatment intervals. Moreover, storage interval and treatments significantly affected the sensory attributes of functional fudge.
