Effect of Cooking Time and Storage Temperature on the Quality of Home-Made Retort Pouch Packed Chuncheon Dakgalbi

초록

The aim of this research is to evaluate the effects of cooking time and storage temperature on the quality of home-made retort pouch packed Chuncheon Dakgalbi. The leg meat of broiler is being cut into cubes and is mixed with the Dalcgalbi sauce and vegetables. Around 200 g of Chuncheon Dakgalbi is being stuffed into a retort pouch and then vacuumed. The retort pouch packed Chuncheon Dakgalbi is subjected to cooking (autoclaving) at 110 degrees C and 0.75 Kgf for 10, 20 or 30 min and then transferred to the chilling room at 2 degrees C for rapid cooling procedures. Subsequently, the samples are stored at 4 degrees C or 25 degrees C for 4 wk. According to results of sensory evaluation, the highest sensory scores were found in Chuncheon Dakgalbi which was cooked for 30 min (p<0.05). Prolonged cooking time tends to decrease the pH, CIE L* and CIE a* levels, and slightly promote the lipid oxidation and protein deterioration. The Chuncheon Dakgalbi being cooked for 10 min promoted the lipid oxidation and protein deterioration during storage at 25 degrees C. Moreover, the total aerobic and anaerobic bacteria in Chuncheon Dakgalbi being cooked for 10 min started to grow after 3 wk of storage at 25 degrees C. Cooking (autoclaving) at 110 degrees C for 30 min is able to maintain the quality and shelf-life of retort pouch packed Chuncheon Dakgalbion the market.
