چکیده

Banana is one of the most important crops, providing multiple benefits. Although it has been widely studied for its health benefits, little information can be found about proteins. This study determined antihypertensive and antioxidant activities crude, purified, hydrolyzed protein extracts from ‘Señorita’ banana pulp. Crude proteins were extracted using Tris-HCl buffer purified through ammonium sulfate precipitation, dialysis, gel filtration chromatography. The content partially to 167.32, 120.45, 28.51 μg·mL−1, respectively, with major having an approximate molecular weight 15 kDa. These then subjected enzymatic hydrolysis release bioactive peptides prior ACE inhibitory determination. Among these samples, undigested crude extract had highest activity (85.20%). There was also observable increase in inhibition digested samples increased digestion time. Meanwhile, 3-h 4-h digests DPPH radical scavenging 30.82% 34.74%, respectively. not significantly different standard, ascorbic acid. A general decrease observed observations coherent silico analysis putative protein, lectin, which showed that releases inhibitor peptides.

Extraction and characterization of pectin from Saba banana [Musa ‘saba’(Musa acuminata x Musa balbisiana)] peel wastes: A preliminary study

Saba banana, Musa ‘saba’(Musa acuminata x Musa balbisiana) peel is an underutilized waste from processed banana manufacturing in the Philippines. The feasibility of saba banana peel pectin for use in food processing was assessed. Pectin from saba banana peel was extracted under two different extraction conditions. Pectin extraction was carried out using hydrochloric acid (0.5N, pH 1.5) and citr...

Carbohydrate binding properties of banana (Musa acuminata) lectin

Examination of lectins of banana (Musa acuminata) and the closely related plantain (Musa spp.) by the techniques of quantitative precipitation, hapten inhibition of precipitation, and isothermal titration calorimetry showed that they are mannose/glucose binding proteins with a preference for the a-anomeric form of these sugars. Both generate precipitin curves with branched chain a-mannans (yeas...
