Kestabilan Oksidatif Pakan Induk Udang Air Tawar (Macrobrachium idae)dengan Salut Antioksidan Alami

Abstract

Macrobracium idea feed contains high level of carotenoid and lipid that easily. The stability of this feed can be sustained using herbal antioxidant coating derive from extract of green tea (Camelia sinensis) leaves, guajava (Psidium guajava) leaves, dan ginger (Zingiber officinalis) roots. The objective of this experiment was to evaluate the application of herbal antioxidant derived from blended extract of green tea leaves, gujava leaves, and ginger roots tolipid stability of freshwater prawn broodstock feed. There are two types of feed, low carotenoid as control feed and high carotenoid as treatment feed. Coating was made of herbal extract mixed with cassava flour (25%). Feed was added coating (1:1) and cassava flour (26%). Positive control coating was BHT (0.01%). The feed were challenge to white florescent lamp for 12 hours. There were six tests: coating control feed without herbal antioxidant and BHT (K1), coating control feed with herbal antioxidant (K2), coating control feed with BHT (K3), coating treatment feed without herbal antioxidant and BHT (P1), coating treatment feed with herbal antioxidant (P2), coating treatment feed with BHT (P3). The result shows that free fatty acid (FFA) value of herbal antioxidant was significantly (P<0.05) lower than coating without herbal antioxidant and BHT, both of control and treatment feed. Herbal antioxidant was as good as BHT to protect the oxidative stability of feed. In conclusion, antioxidant derived from extract of of green tea leaves, gujava leaves, dan ginger roots can be used to protect oxidative stability of freshwater prawn broodstock feed.
