Abstract

The aim of this research is to evaluate the physicochemical characteristics of anthocyanins from mangosteen peel extract and bio-based film as smart packaging indicator on the chicken meat deterioration during storage. An indicator can be defined as a substance which indicates the presence or absence of another substance or the degree of a certain reaction through characteristic changes, especially colour. This research used Complete Randomized Design with two factors and three replications. First factor was temperature storage which was T1 (± 270C) and T2 (± -20C). Second factor was storage time consisted of 0-6 days (t1) and 0-28 days (t2) . The results showed the physicochemical characteristics of anthocyanins from mangosteen peel extract with the value of anthocyanin total 37.57 mg/L, pH value 1.3, Lightness (L*) 18.06, redness (a*) 31,88 and yellowness (b*) value 6.52. The physicochemical characteristics of bio-based film indicator stored at ±270C during 6 days period showed the value of colour change is 0hue 57.61 (yellow-red) into 40.46 (red), the pH value (4,28-7,26), total anthocyanins (2.58-1.58 mg/L). The physicochemical characteristics of bio-based film indicator stored at ±-20C during 28 days period showed the value of colour change is 0hue 63.61 (yellow-red) into 59.57 (yellow-red), the pH value (4.34-4.70), total anthocyanins (2.83-0.16 mg/L).
