Quality changes of giant freshwater prawn (GFP) Macrobrachium rossenbergii coated
with 1.25% BHT, 0.25% and 0.50% Annona muricata (AME) leaves extract was
monitored during storage at 4 ºC for 15 days. AME extract was prepared using distilled
water and dried to syrup concentration using rotavap followed by freeze drying at -
80°C. Changes in bacterial load of each treatment were compared from the day 0 until
day 15. TBC on each treatment showed an increasing trend as the period of chilled
storage prolonged. At the end of chilled storage, TBC in GFP soaked with 0.25% and
0.50% AME were recorded at 6.105 ± 0.046 and 5.061 ± 0.076 log10 cfuml -1
respectively. This are the range of fresh seafood by International Commission on
Microbiological Specifications for Foods (ICMSF). In conclusion, AME have an economic
potential to become effective agent to lower the microbial growth and act as edible
antimicrobial preservative.
