Effect of bottle gourd leaf (Lagenaria siceraria) extract on the quality of beef meatball

Abstract

The experiment was conducted to find out the effect of different levels of bottle gourd leaf extraction on beef meatballs. Ground beef samples were divided into four treatment groups having bottle gourd leaf extracts as control T1 (0%), T2 (1%), T3 (2%), T4 (3%). Proximate analysis, sensory tests (color, flavor, tenderness, juiciness, and overall acceptability), cooking loss, pH value, free fatty acids (FFA), thiobarbituric acid values (TBARS), peroxide value (POV) and microbiological examination were determined. Days of intervals of experiment were 0, 15th, 30th and 45th days. Data were analyzed using SAS Statistical software. DM content of all the treatment groups differ significantly (p<0.05). In contrast, DM content increased significantly (p<0.05) with the advancement of different days of intervals. The CP and EE content at different treatment levels differ significantly (p<0.05). The FFA, TBARs, POV values were decreased significantly (p<0.05). The color, flavor, tenderness, juiciness, overall acceptability, raw and cooked pH were increased at different treatment levels significantly (p<0.05). The cooking loss (%) with the advancement of days of intervals were differ significantly (p<0.05). TCC (log CFU/g) and TYMC (log CFU/g) were decreased significantly (p<0.05) at different treatment levels. Parameters studied showed that, 2% bottle gourd leaf extract added meat balls were the best quality, so it may be concluded that 2% bottle gourd leaf extract can be used in beef meatball as a source of antioxidant and antimicrobial agent to increase shelf-life of meatballs.

Quality Assessment of Beef Using Computer Vision Technology

“…The average values with standard deviations were 5.09±0.05, 5.91±0.07 and 7.7±0.08 for TCC, TYMC, and TVC respectively. The TVC level of this study was in close agreement with the findings of Saba et al (2018) but the TCC and TYMC value were higher than results of Murshed et al (2016), Afrin et al (2017) and Alam et al (2017) . The possible cause of this variation in microbial load might be due to the differences in the aging period.…”

Antimicrobial activity of bottle gourd leaf extract and its effect on the quality of food

“…The result indicated that bottle gourd contains natural antioxidants reduced the oxidative rancidity in sausage samples. This result agrees with (Saba et al, 2018). The results presented in the table (4) showed that the range of overall observed pH value at bottle gourd leaf extract treatments was 5.86 to 6.13.…”

Effect of Different Level of Lemon Extract on Quality and Shelf Life of Chicken Meatballs During Frozen Storage

“…Consumers have shifted their interest to natural antioxidants since these are considered safer than synthetic antioxidants. All natural antioxidants, especially of plant source, have greater application potential for consumer's acceptability, palatability, stability, and shelf life of meat products (Jung et al, 2010;Saba et al, 2018). Plant extracts like herbs, spices etc.…”
