PENGARUH LEMON KALAMANSI (Citrus microcarpa) TERHADAP KOMPOSISI KIMIA DAN FITOKIMIA ANTIOKSIDAN DARI TEPUNG PISANG GOROHO (Musa spp.)

Abstract

ABSTRACT Suryanto et al., 2011. Effect of callamansi citrus (Citrus microcarpa ) on chemical composition and antioxidant phytochemical of Goroho (Musa spp.) banana flour. The objective of this research was to study chemical composition and measured antioxidant activity of goroho banana flour which immersed with callamansi. The goroho banana was soaked with water, callamansi and sodium methabisulfit for 60 minute. Furthermore, each flour were analyzed its phytochemical such as, proximate analysis, total phenolic content, flavonoid, condensed tannin, carotenoid, ascorbic acid, total antioxidant using titration and spectrophotometer method. The results showed that callamansi addition of 1% was the best treatment for banana flour. The product had content of moisture, ash, fat, protein, fiber and carbohydrate were 4.29 ± 0.01; 3.74 ± 0.02; 3.03 ± 2,04; 1.47 ± 0.57; 4.75 ± 0.57 and 85.70 ± 0.59, respectively. The banana flour soaked with callamansi for 60 minute had phenolic, flavonoid, condensed tannin total content were 55.82 ± 0,01; 6.27 ± 0.08 and 36.50 ± 0.24 mg/kg, respectively. Whereas ascorbic acid and carotenoid total content of goroho banana flour were 51.92 ± 3.73 and 6.36 ± 1.13mg /kg sample, respectively. Total antioxidant of banana flour extract soaked with callamansi shows high activity compared without soaked and soaked with sodium methabisulfit for 60 minute. The results showed that banana flour immersed with calamansi extract and sodium metabisulfit possess different proximate composition (p<0.05). Banana immersed with calamansi extract appears to increase phenolic, flavonoid, condensed tannin, ascorbic acid content as well as the capacity antioxidant of banana four.
