Semi-dried mulberry fruit can be distributed at room temperature and maintained its chewy texture and shape. It can be used for its own itself or food materials. We develop the honey coating semi-dried mulberry fruit manufacturing method through hot air dryer. After extracting the moisture from the thawing process, honey was coated and dried. Drying time for semidried mulberry fruit was shortened by manufacturing on the day of work without going through aging process. The first the mulberry fruit juice was separated from the frozen mulberry fruit at room temperature of the laboratory or in the dryer of $60{\sim}90^{\circ}C$, then the first dried by a hot air drier at $60^{\circ}C$ for 3 to 4 h. Next, it is coated with honey, which is equivalent to 20% weight of the first dried mulberry fruit, and then the second dried at a temperature of $38^{\circ}C$ for 20 ~ 30 h. The honey coating semi-dried mulberry fruit by above method was shiny on the surface and retained its shape. The moisture content was about 15% and it was confirmed that it could be stored at room temperature.

Semi-dried conger eel Conger myriaster is considered as a health food in Korea due to its richness in vitamins, minerals, proteins and omega-3 fatty acids. This study characterize the sanitary quality of commercial semi-dried conger eel for developing high quality semi-dried products and suggested the guideline for controlling the quality. Moisture content ranged from 41.2% to 73.4% (mean: 61.5%), volatile basic nitrogen ranged from 16.1 to 93.6 mg/100 g (mean: 55.1 mg/100 g), and peroxide value ranged from 15.2 to 69.8 meq/kg. Viable cell counts ranged between 6.51 and 8.53 log CFU/g, while the Escherichia coli count ranged from undetectable to 4.6 log CFU/g. Based on these chemical and microbial findings, we suggest that provisions be established for development of high quality semi-dried conger eel as follows: 50-68% for moisture content, < 50 mg/100 g for volatile basic nitrogen content, < 60 meq/kg for peroxide value, and negative for E. coli. Among the 16 commercial semi-dried conger eel products used in this study, the standard-passed product was only GS-L.

Semi-dried restructured sausages are restructured meat products with a high nutritional and economic value. However, excessively long drying times can have negative effects on the energy consumption, texture, and sensory properties of semi-dried restructured sausages. The objective of this study was to investigate the effects of different water contents on the drying and physicochemical characteristics of semi-dried restructured sausages. Sausages were prepared with different initial moisture contents (0%-50%) and drying time (0-580 min). The drying characteristics, including the drying rate, effective moisture diffusivity, and water activity of sausage were significantly improved as the initial moisture content was increased. When the initial moisture content of the sausage was 50%, physicochemical properties, such as color, porosity, shear force, and volatile basic nitrogen, were improved the most along with the decreased drying time. Scanning electron microscopy data showed greater porosity and pore size in sausages with the increase of initial moisture content. Collectively, our data suggest that an increase in the initial moisture content of semi-dried restructured sausages improves their drying characteristics and physicochemical properties.

영양생리적 기능이 우수하며, 식품위생적인 면으로도 안전하여 소비자들의 기호에 맞는 반염건고등어를 제조한 다음, 이의 효율적 이용을 위해 저온저장 중 품질안정성에 대하여 검토하였다. 제조직 후 반염건고등어의 수분함량은 $59.4{\sim}62.4%$의 범위였으나 저온저장 중 전제품이 약간씩 감소하였다. 저장 중 생균수는 저장 5일 초기의 경우 탈수방법의 차이에 관계없이 거의 변화가 없거나 약간 감소하였으나 저장 중기 이후에는 계속 증가를 하였고, 그 증가폭에 있어서는 거의 차이가 없었다. Histamine 함량의 경우 전제품 모두 제조직 후 $2.5{\sim}3.6mg/100g$의 범위였고, 저장 15일째에도 $3.6{\sim}4.1mg/100g$을 수준으로 histamine의 식중독 한계선인 100mg/100g에는 훨씬 못미치는 함량이었다. 저장 중 반염건고등어의 과산화물값, 혼합지방산 조성 및 갈변도 변화의 결과로 미루어 탈수시트로 탈수하여 제조한 반염건고등어가 재래식 건조법에 의하여 제조한 반염건고등어보다 저장 중 지질산화가 억제되었다. 저장일수가 경과할수록 염용성질소의 용해도는 감소하였고, 그 감소폭은 탈수시트로 제조한 반염건고등어가 전통적인 방법으로 제조한 것보다 적었다. 텍스튜어의 경우 제조방법에 관계없이 저장일수가 경과할수록 경도는 감소하는 경향을, 응집력은 거의 변화가 없거나 증가하는 경향을 나타내었고, 이등의 값은 탈수시트로 제조한 반염건고등어가 재래식건조법에 의하여 제조한 반염건고등어보다 높았다. 이화학적 검사 및 관능검사의 결과로 미루어 볼 때 탈수시트로 제조한 반염건고등어가 재래식방법으로 제조한 것보다 품질유지기간이 긴 것으로 판명되었다.

The present study investigated the effects of duck skin gelatin and carrageenan on the quality of semi-dried restructured jerky. Restructured jerky was prepared as follows: G0 (control, without duck skin gelatin and carrageenan), G0C (0.3% carrageenan), G0.5 (0.5% duck skin gelatin), G0.5C (0.5% duck skin gelatin and 0.3% carrageenan), G1 (1.0% duck skin gelatin), and G1C (1.0% duck skin gelatin and 0.3% carrageenan). The moisture content was the highest for the semi-dried restructured jerky from G0.5C and G1C groups, which showed the lowest for shear force value (p < 0.05). The processing yield of semi-dried restructured jerky with carrageenan was higher compared to that of the control group (p < 0.05). The rehydration capacities of G0.5, G0.5C, and G1C groups were significantly higher than the rehydration capacity of the control group (p < 0.05). Water activity, lightness, yellowness, flavor score, texture score, and overall acceptability were the highest (p < 0.05) for the semi-dried restructured jerky from the G1C group. No significant (p > 0.05) difference was observed in appearance score among restructured jerky prepared from duck skin gelatin and carrageenan. Thus, the addition of 1.0% duck skin gelatin and 0.3% carrageenan to semi-dried restructured jerky formulations results in the optimization of quality characteristics.

Effects of the addition of kimchi powder on the physico-chemical and sensory properties of semi-dried sausages were investigated at the following kimchi powder concentrations: control (0%), T1 (1%), T2 (2%), and T3 (3%). pH of the semi-dried sausages containing kimchi powder decreased with the addition of kimchi (p<0.05). Also, the addition of kimchi powder to the sausages significantly decreased the CIE $L^*$ and increased the CIE $a^*$ and CIE $b^*$ values (p<0.05). The T3 treatment resulted a higher mositure lose than other treatments. TBARS values of the T2 and T3 groups were significantly lower (p<0.05) than that of the control, while T3 had the highest VBN value among treatments at the end of the storage period. Addition of kimchi powder to semi-dried sausages improved the overall sensory properties of the sausages, and increased the softness and tenderness. These results suggest that addition of 2% kimchi powder to semi-dried sausage is helpful to improve the quality of sausages.

The objective of this study was to investigate the effects of replacing sucrose with sugar alcohols (sorbitol, glycerol and xylitol) on the quality properties of semi-dried jerky. Total 7 treatments of jerkies were prepared as follows: control with sucrose, and treatments with 2.5 and 5.0% of sucrose replaced by each sugar alcohol, respectively. Drying yield, pH, water activity, moisture content, shear force, myofibrillar fragmentation index (MFI), 2-thiobarbituric acid reactive substance (TBARS) value, sugar content, and sensory evaluation were evaluated. Xylitol slightly decreased the pH when compared to the other sugar alcohols (p>0.05). The water activity of the semi-dried jerky was significantly reduced by treatment with glycerol and xylitol (p<0.05). The moisture content of semi-dried jerky containing various sugar alcohols was significantly higher than that of the control (p<0.05), while replacing sucrose with glycerol yielded the highest moisture content. The shear force of semi-dried jerky containing sugar alcohols was not significantly different for the sorbitol and glycerol treatments, but that replacing sucrose with 5.0% xylitol demonstrated the lowest shear force (p<0.05). The TBARS values of semi-dried jerkies with sugar alcohols were lower than the control (p<0.05). The sugar content of the semi-dried jerkies containing sorbitol and glycerol were lower than the control and xylitol treatment (p<0.05). In comparison with the control, the 5.0% xylitol treatment was found to be significantly different in the sensory evaluation (p<0.05). In conclusion, semi-dried jerky made by replacement with sugar alcohols improved the quality characteristics, while xylitol has applicability in manufacturing meat products.
