Application of vitamin C and green tea alginate-based coating and modified atmosphere packaging to prolong shelf-life of cooked squid: vitamin C and green tea coating
Abstract:
There was 4 attributes as appearance, odor, flavor and texture for sensory
acceptance. An odor attributes was not exceed than 3 score, which could use to be
shelf life of cooked squid coated with an alginate-based coating incorporating with
vitamin C and green tea. The effect of vitamin C and green tea coating on the
shelf life extending of cooked squid (Loligo spp.). The alginatebased coating
incorporating with vitamin C and green tea four different conditions: T125 (1% green
tea, 2.5% vitamin C), T115 (1% green tea, 1.5% vitamin C), TAC (0.002% alginate) and
TCC (uncoated) during refrigerated storage of 22 days was investigated. T125 was the
most effectively retarded chemical (pH, moisture, TVB-N and TMA-N), physical (%
cooking loss, L* a* b* and shear force), microbiological quality (total bacterial count)
qualities loss of cooked squid followed by T115, TAC and TCC, respectively. T115
was the most effectively retarded sensorial (appearance, odor, texture and tasty)
qualities loss of cooked squid followed by T125, TAC and TCC, respectively.
Considering the product shelf life by the microbiology quality loss (total plate count
was not exceeded 6 log CFU/g), which were faster than the sensorial evaluation
(odor scores were less than 3 score). While still made it safe for consumption so the
shelf life of T125 and T115 were 18 days. The TAC and TCC was shelf life by 10 days.
