This study was conducted to evaluate the effect of pre-rigor salting level (0-4% NaCl concentration) on physicochemical and textural properties of pre-rigor chicken breast muscles. The pre-rigor chicken breast muscles were de-boned 10 min post-mortem and salted within 25 min post-mortem. An increase in pre-rigor salting level led to the formation of high ultimate pH of chicken breast muscles at post-mortem 24 h. The addition of minimum of 2% NaCl significantly improved water holding capacity, cooking loss, protein solubility, and hardness when compared to the non-salting chicken breast muscle (p<0.05). On the other hand, the increase in pre-rigor salting level caused the inhibition of myofibrillar protein degradation and the acceleration of lipid oxidation. However, the difference in NaCl concentration between 3% and 4% had no great differences in the results of physicochemical and textural properties due to pre-rigor salting effects (p>0.05). Therefore, our study certified the pre-rigor salting effect of chicken breast muscle salted with 2% NaCl when compared to post-rigor muscle salted with equal NaCl concentration, and suggests that the 2% NaCl concentration is minimally required to ensure the definite pre-rigor salting effect on chicken breast muscle.

The pre-rigor salting effects on physicochemical properties of ground duck breast muscle were evaluated in this study. The pre-rigor salting treatments were prepared within 30 min after slaughter, the duck breast muscles after post mortem 48 h were used to prepare the post-rigor treatments. The pre-rigor salting treatment had significantly higher pH value than post-rigor salting treatment (p<0.001), and all pre-rigor salting treatments showed a significant higher pH value. As a result, the pre-rigor salting treatment showed increased water holding capacity and decreased cooking loss compared to those in the post-rigor salting treatment. No significant differences in redness and yellowness were observed among the treatments (p>0.05). The increased solubility of salt-soluble proteins in the pre-rigor salting treatment leads to increase the hardness, gumminess, and chewiness. Also, the pre-rigor salted duck breast muscle had similar textural properties compared to those of post-rigor duck breast muscle containing sodium tri-polyphosphate (STPP). The 2-thiobarbituric acid (TBA) values of all treatments were ranged from 0.121 to 0.177 mg/kg. The lowest TBA value was observed for post-rigor duck breast muscle containing STPP, however, pre-rigor salting did not influence lipid oxidation of ground duck breast muscle. Therefore, the pre-rigor salting method, especially a single addition of sodium chloride to pre-rigor muscle, is more efficient method for improving cooking loss.

To investigate pre-salting conditions in the preparation of salted anchovy from large anchovy, anchovy were salted with various salt concentration and stored at $5^{\circ}C$ and $20^{\circ}C$ for 10 days. Moisture content decreased with the increase of salt and the salinity increased in proportion to salt concentration at $20^{\circ}C$. Total nitrogen decreased slightly as the increase of salt concentration during pre-salting at $20^{\circ}C$. The nitrogenous components such as amino nitrogen and extractable nitrogen were invariable or decreased until 7 days in salt concentration over $25\%$ during pre-salting at $5^{\circ}C$. These results imply that soluble nitrogen with moisture run out of anchovy body in high salt concentration and the hydrolysis was inhibited by salt over $25\%$ at $5^{\circ}C$. VBN content were constant in salt concentration over $25\%$ until 7 days, regardless of curing temperature. The POV were under the influence of salt concentration and temperatures. We concluded that the optimal condition for preparation of salted anchovy were pre-salting with salt over $25\%$ at $5^{\circ}C$ for 7 days.

This experiment was conducted to determine the effects of the pre- and post-harvest variable factors on the processed product of kimchi cabbage. Two kimchi cabbage cultivars, namely 'Chungwang' and 'Dongpung,' were grown in a field and under a plastic greenhouse condition and stored at $5^{\circ}C$ after harvesting with and without low-density polyethylene (LDPE) film packaging. Growths were determined after harvesting while salting characteristics were determined after the processing and storage. The results show that the height, weight and leaf thickness were higher in kimchi cabbages grown in the greenhouse than those grown in the field. The plastic house culture increased the kimchi cabbage growth of the head weight, head height and leaf thickness compared with that of the open field culture. However, the osmolality and firmness were higher in the outdoor cultivated kimchi cabbages. Kimchi cabbage packed in film covered sacks and stored at $5^{\circ}C$ showed lower weight loss than unpacked cabbages during storage. Salt concentration and pH were also affected by the different pre- and post-harvest factors after salting the kimchi cabbages. Salt concentrations of the kimchi cabbage were influenced by various factors such as the cultivars, cultivation methods and storage covering. Though the present findings showed a limited difference in salt concentration and pH between the cultivars of kimchi cabbages, this study suggests that there is a relationship between processed agricultural products and their pre- and post-harvest methods.

Anchovy fillet 제조를 위하여 염장방법 및 숙성온도에 따른 염장 멸치의 숙성 중 성분변화를 조사하였다. 물간에 비하여 마른간 하였을 때 육의 탈수량이 많았으며, $20^{\circ}C$에 숙성한 것이 $5^{\circ}C$에 비하여 수분함량이 다소 낮았다. 염분함량은 물간한 것이 마른간에 비하여 높았으며, $20^{\circ}C$에서 숙성 한 것이 $5^{\circ}C$에 비하여 높았다. 총 질소는 물간이 마른간한 것에 비하여 낮았으며, 염장 초기에 총질소의 저하가 현저하였다. 마른간이나 물간 모두 $20^{\circ}C$에서 염장 멸치의 숙성 중 아미노태질소가 현저하게 증가하여 마른간은 숙성120일, 물간은 숙성 30일에 거의 최대를 나타낸 반면, $5^{\circ}C$에서는 미미한 증가를 보였다. 휘발성염기질소의 변화는 아미노태질소와 거의 비슷한 경향을 나타내었다. 물간한 것은 마른간에 비하여 동일 온도에서 가수분해가 빠르게 진행되었으며, $5^{\circ}C$에서는 가수분해가 현저하게 억제되었다. 과산화물가는 마른간이 물간에 비하여 빠르게 증가하였으며, $5^{\circ}C$에 숙성한 것이 $20^{\circ}C$에 비하여 낮은 과 산화물가를 나타내었다. 이상의 결과로 보면, 염장 멸치의 제조를 위해서는 대멸치를 가염지 한 다음, $25\%$의 식염으로 마른간하여 $5^{\circ}C$에서 숙성시키는 것이 육의 연화를 막고, 숙성이 어느 정도 진행된 염장 멸치론 얻을 수 있을 것으로 사료된다.

This study was conducted to examine the effect of salt concentration in soybean sauce (ganjang) on pre-rigor ground Hanwoo (Korean native cattle) muscle. Although adding soybean sauce reduced pH of pre-rigor Hanwoo muscle, it improved the water holding capacity (WHC), cooking loss, total protein solubility, myofibrillar fragmentation index (MFI), 2-thiobar-bituric acid (TBA) values, and textural properties by increasing salt concentration in the soybean sauce. In particular, adding soybean sauce inhibited lipid oxidation despite increasing salt concentration. An increased salt concentration in the soybean sauce in pre-rigor Hanwoo muscle tended to make the meat have lower lightness and higher redness and yellowness values. Although soybean sauce had a significantly lower pre-rigor salting effect than sodium chloride in terms of cooking loss and total protein solubility (p<0.05), soybean sauce improved myofibrillar fragmentation and lipid oxidation when compared with sodium chloride. Furthermore, no significant differences in textural properties were observed between adding soybean sauce and sodium chloride at the same salt concentrations. Therefore, soybean sauce can be a functional curing material for pre-rigor muscle.

In this study, the effects of a pre-filter system and electrolysis system on the safe and efficient reuse of brine in the cabbage salting process were investigated. First, sediment filter-electrolyzed brine (SF-EB) was selected as brine for reuse. Then, we evaluated the quality and microbiological properties of SF-EB and Chinese cabbage salted with SF-EB. The salinity (9.4%) and pH (4.63) of SF-EB were similar to those of control brine (CB). SF-EB turbidity was decreased (from 0.112 to 0.062) and SF-EB residual chlorine (15.86 ppm) was higher than CB residual chlorine (0.31 ppm), and bacteria were not detected. Salinity (2.0%), pH (6.21), residual chlorine (0.39 ppm), chromaticity, hardness, and chewiness of cabbage salted with SF-EB were similar to those of cabbage salted with CB. The total bacterial count in cabbage salted with CB was increased as the number of reuses increased (from 6.55 to 8.30 log CFU/g), whereas bacteria in cabbage salted with SF-EB was decreased (from 6.55 to 5.21 log CFU/g). These results show that SF-EB improved the reusability of brine by removing contaminated materials and by sterilization.

The purpose of this study was to investigate changes in physicochemical properties of apples pre-treated differently with salt and sugar for apple Jangachi. When salt was used, moisture content was decreased by 28.41% to 57.67% at 24 hours and maintained an average 56.92% after 24 hours. However, when sugar was used, moisture content decreased steadily to 41.14% (60h). The pH of the apple pre-treated with salt decreased from pH 4.42 to pH 3.63 at 12 hours. However, in the case of apples pre-treated with sugar, pH decreased from pH 4.52 to pH 4.19 after 48 hours, but was not statistically significant. Conversely, total acidity of apple pre-treated with salt increased from 11.46% to 0.35% during 72 hours. But total acidity of apple pre-treated with sugar decreased to 0.11% at 24 hours and maintained. Sugar content of apple pre-treated with salt increased to 33.1% at 12 hours and maintained. Conversely, in case of sugar pre-treatment, sugar content of apple pre-treated with sugar increased steadily to 45.12% at 72 hours. Salinity of apple pre-treated with salt increased sharply to 15.74% during 24 hours. Lightness ($L^*$) of apple pre-treated sugar was not different from the control group. But apple pre-treated salt decreased slightly. Yellowness ($b^*$) was higher than the control group regardless of pre-treatment group. Sensory evaluation revealed that sugar pre-treatment apples were highly evaluated for flavor, taste, chewiness and overall acceptance.

본 연구는 한국인의 주요 부식 김치의 주재료인 배추의 연중 수급 안정화를 목적으로 봄배추 저장기간 연장의 최적조건을 확립하고자 수행되었다. 저장조건 및 기간별 김치를 제조하여 숙성 중 변화를 연구한 실험 결과, 정선손실률은 저장 12주차에 크게 증가하였으며, 저장 6주와 12주 배추 모두 플라즈마+역방향+예건+HDPE film 처리구의 손실률이 가장 낮았다. 저장 12주 배추의 절임수율과 김치수율은 저장방법에 있어 정방향 처리구에 비하여 역방향+예건+HDPE film 처리구가 높게 나타났으나, 전반적인 수율이 저장 6주와 비교할 때 급격히 저하되어 상업적 가치는 낮은 것으로 판단되었다. 경도는 제조직후에 비하여 숙성 1개월부터는 저장기간에 따른 차이가 미미하였으나, 이 중 저장 6주 배추는 숙성 1개월부터 광촉매+정방향 처리구가, 저장 12주 배추는 저온저장+정방향 처리구가 가장 높았다(p<0.05). 숙성 2개월째에 저장 6주의 광촉매+정방향 처리구와 12주의 플라즈마와 저온저장의 정방향 처리구가 염도의 변화가 적은 것으로 나타났으며, pH와 산도는 역방향+예건+HDPE film 처리구의 변화가 적어 정방향 처리구보다 숙성이 느리게 진행되는 것을 알 수 있었다(p<0.05). 관능평가 결과, 전반적으로 적입 및 전처리 방법에 있어서 정방향 처리구에 비해 역방향+예건+HDPE film 처리구가 우수한 점수를 얻었으며, 저장방법에 있어서는 저장 6주와 12주 배추 모두 플라즈마와 광촉매 저장기술을 이용한 처리구의 평가가 저온저장고($0.5^{\circ}C$)에서 저장한 처리구에 비해 높았으며, 특히 김치의 적숙기로 볼 수 있는 숙성 1개월째에는 플라즈마, 광촉매, 저온저장 순으로 높은 점수를 기록하여 플라즈마 및 광촉매 등 고도화 기술의 이용이 유용할 것으로 사료되었다. 다만 숙성기간이 길어질수록 질감에는 큰 차이가 없었으나, 냄새, 맛, 전체적인 기호도에 있어 저온저장($0.5^{\circ}C$) 처리구의 점수가 높아진 것으로 나타나, 장기 숙성을 요하는 묵은지 제조 등에는 저온저장($0.5^{\circ}C$)이 더 적합할 것으로 판단된다.
