Effect of Aloe vera Extract in Reducing Formaldehyde in Salted Squid (Loligo indica) and Sensory Evaluation

Abstract

This study aims to determine the effect of Aloe vera extract in reducing formaldehyde levels in salted squid and determine the organoleptic characteristics of salted squid after being given Aloe vera extract. This study used a completely randomized design (CRD) with 4 treatments and 6 replications: P0 (0% Aloe vera extract), P1 (10% Aloe vera extract), P2 (20% Aloe vera extract), and P3 (30% Aloe vera extract). Data were analyzed by using an analysis of variants at a significant level α = 0.05 followed by Duncan's Test. The average formalin content before given aloe vera extract in P0, P1, P2, P3 was 3.65 mg / L, 4.08 mg / L, 4.09 mg / L, 3.96 mg/ L, respectively and after being given aloe vera extract was 2.75 mg/L, 2.58 mg / L, 1.63 mg / L, 2.82 mg / L, respectively. Administration of Aloe vera extract showed a significant reduction of formaldehyde levels in salted squid (p<0.05). Moreover, it was affecting the quality of salted squid in terms of color, aroma, and texture. It can be concluded that the administration of 20% Aloe vera extracts effective for reducing the formaldehyde levels, improve the quality of color, aroma, and texture in salted squid.
