  • As the blueberry content in batter increased, the pH of batter decreased According to the measured results about specific gravity of muffin batter, there was no significant difference among each batter including 0% 10% and 15% blueberry, while each 15% 20% and 30% dough showed significant difference (p<0.001). According to the results about general quality characteristics of muffins such as volume, weight and specific gravity, as the content of blueberry juice increased, the volume decreased. In terms of measuring specific volume, it decreased as the added amount increased According to measuring the chromaticity of muffins, as the blueberry content increased in the muffins, brightness and yellowness decreased while redness increased In terms of the measurement of texture, the hardness showed significant difference among all sample muffins (p<0.001). Significant difference was not shown in the springiness (p<0.05). As the amount of blueberry juice increased, the chewiness of the muffins was grown. The result showed a significant difference between samples in the adhesiveness (p<0.001). As the amount of blueberry juice increased, the adhesiveness of muffins also increased In the organoleptic test, a significant difference was shown in the color among all sample (p<0.001). The blueberry juice content of 20% showed highest figures with $7.12{\pm}0.67$. In terms of flavor, the content of 20% also showed highest figures among all samples with $7.16{\pm}0.62$ (p<0.001). Concerning the taste all samples showed a significant difference while 20% content did the highest figure. In the overall acceptability the content of 10% showed the lowest figure while 20% displayed the highest figure with 7.16.

  • Objective: The aim of this study was to evaluate the effect of marinating turkey meat with buttermilk and acid whey on the technological traits and microbiological quality of the product. Methods: Slices of turkey meat muscles were marinated for 12 hours in buttermilk (n = 30), acid whey (n = 30) and comparatively, in lemon juice (n = 30). The control group (n = 30) consisted of unmarinated slices of turkey breast muscles. Physical parameters (pH, water holding capacity, colour L*a*b*, shear force, weight loss) were assessed and quantitative and qualitative microbiological evaluation of raw and roasted products was performed. The microbiological parameters were determined as the total viable counts of mesophilic aerobic bacteria, of the Enterobacteriaceae family, and Pseudomonas spp. Bacterial identification was performed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Results: Marinating turkey meat in buttermilk and whey compared to marinating in lemon juice and the control sample resulted in a higher (p<0.05) degree of yellow color saturation (b*) and a reduction (p<0.05) in the number of mesophilic aerobic bacteria, Pseudomonas spp. and Enterobacteriaceae family as well as the number of identified mesophilic aerobic bacteria in both raw and roasted samples. The lowest (p<0.05) shear force values were found in products marinated in whey. Conclusion: The use of buttermilk and acid whey as a marinade for meat increases the microbiological safety of the product compared to marinating in lemon juice, while maintaining good technological features of the product.

  • This study investigated the effects of the addition levels of white kimchi powder and acerola juice powder, as natural sources of sodium nitrite and sodium ascorbate, on the quality of cooked ground pork products. Freeze-dried white kimchi powder was prepared and used after fermentation for 2 wk. Six treatments were included: control (100 ppm sodium nitrite and 500 ppm sodium ascorbate), treatment 1 (0.2% white kimchi powder, 0.02 % starter culture, and 0.1% acerola juice powder), treatment 2 (0.2% white kimchi powder, 0.02% starter culture, and 0.2% acerola juice powder), treatment 3 (0.4% white kimchi powder, 0.04% starter culture, and 0.1% acerola juice powder), treatment 4 (0.4% white kimchi powder, 0.04% starter culture, and 0.2% acerola juice powder), and treatment 5 (0.4% celery powder, 0.04% starter culture, and 0.2% acerola juice powder). The pH values were decreased (p<0.05) because of lower pH of acerola juice powder, resulting in lower cooking yields (p<0.05) in these treatments. CIE L* and CIE a* values of indirectly cured meat products were not different (p>0.05) from the sodium nitrite-added control. However, indirectly cured meat products showed lower (p<0.05) residual nitrite contents, but higher (p<0.05) nitrosyl hemochrome contents and cure efficiency than the control. Treatments 2 and 4 had higher (p<0.05) total pigment contents and lipid oxidation than the control. This study indicates that white kimchi powder coupled with acerola juice powder has substantial potential to substitute synthetic nitrite to naturally cured meat products, which could be favored by consumers seeking clean label products.

  • 착즙전처리가 배즙의 품질에 미치는 영향을 알아보기 위하여 가열배즙(HPP), 데치기한 후 착즙된 배즙(BPP), 냉동 후 해동하여 착즙한 배즙(TPP)의 품질을 생배즙(Control)과 비교하였다. HPP는 수율과 당도에서 각각 78%, $15^{\circ}Bx$로 타 처리구에 비해 높은 값을 나타냈고, 각 처리구별 주요 당 및 유기산은 처리구별 차이가 없이 과당과 사과산이었다. 무기질의 경우 그 함량이 많은 것은 K, P, Mg 순이었고, Na와 Fe도 소량 검출되었다. 색도는 HPP가 가공중 낮은 L값과 높은 a값을 보였으며, 맛에서는 타처리구에 비해 HPP가 가장 우수한 기호도를 나타내었다. 따라서, HPP의 풍미가 좀 더 개선된다면 새로운 양질의 가공음료의 개발이 가능하리라 생각된다.

  • Objective: The purpose of this study was to investigate the effect of fermented spinach derived nitrite and sodium nitrite on cured pork loin. Methods: The following treatments were prepared using brine (8% [w/v] salt): Control (-), no nitrite added; Control (+), 0.08% (w/v) sodium nitrite brine; T1, 0.04% (w/v) nitrite fermented spinach juice in 0.04% (w/v) sodium nitrite brine; T2, spinach juice in 0.04% (w/v) sodium nitrite brine; T3, 0.04% (w/v) nitrite fermented spinach juice used as sodium nitrite free brine; and T4, spinach juice used as sodium nitrite free brine. T2 and T4 were incubated to allow to reduce nitrate to nitrite. Results: Spinach juice did not affect cooking loss and pH but negatively influenced flavor and overall acceptability (p<0.05). T1 samples containing synthetic and natural nitrites showed the highest redness values. Spinach juice negatively affected volatile basic nitrogen; however, thiobarbituric acid reactive substance values of T1 and T3 were similar to those of controls (+) (p>0.05). Residual nitrite content decreased with decreasing synthetic nitrite levels. T1 and control samples showed no significant differences in overall acceptability (p>0.05). Conclusion: Thus, combined synthetic and natural nitrites improved the quality of cured pork loin.
