Process planning can be defined as determining detailed methods by which parts can be manufactured from the initial to the finished stage. Process planning starts with determining the manufacturing process based on the geometric shape of the part and the machines and tools required for performing this process. Distributed process planning enables production planning to be performed easily by combining the extracted process and various manufacturing resources such as operations and tools. This study proposes an algorithm to determine the process for a feature-based model and to combine manufacturing resources for the process and implements a distributed process planning system.

Background: This study was carried out to determine the physicochemical components of Rehmannia glutinosa (RG) fermented with Rhizopus delemar. Methods and Results: Physicochemical components such as changes in moisture content, pH value, total acidity, amount of reducing sugars as well as quantity of free sugars, free amino acids, and catalpol were investigated. Result showed that, the moisture content ranged from 64.26 to 65.51%. The pH and total acidity of the fermented RG decreased significantly during fermentation. The reducing sugar content ranged from 0.10 to 1.34%. The most abundant main free sugars were identified as raffinose, xylose, glucose, fructose, and sucrose. The sucrose content in 80% ethanol and in water extracts increased during RG fermentation. In total, 26 free amino acids were detected, including seven essential amino acids. In addition, the quantity of free amino acids decreased significantly during fermentation. Finally, the catalpol content of the fermented RG was highest on the $2^{nd}$ day of fermentation at 2,028.67 mg/ 100 g. Conclusions: These results indicated that fermentation of Rhizopus delemar could be used to enhance biological activity, and that fermented RG could be used as a functional material and as an edible resource in food and functional materials industries.

This study explored a method to enhance the drying process usability of local mangoes by producing foam-mat dried powder under varying drying temperatures (50, 60, 70℃) and foam thicknesses (3, 6, 9 mm). The drying process period ranged from 60 to 390 minutes based on the set conditions, with higher temperatures and thinner foams accelerating drying. Powder chromaticity (L^*,(L^*, a^*, and b^*) demonstrated a declining trend with increasing drying temperature and foam thickness, exhibiting notable variance in chroma values. The water absorption index varied significantly, between 3.08 to 4.24, under different drying conditions, although the water solubility index remained consistent across foam-dried samples. Powder moisture content ranged from 2.53% to 3.83%, with hygroscopicity escalating with temperature and foam thickness. Vitamin C structure was compromised during the hot air drying process, especially at temperatures above 60℃. Electronic nose analysis distinguished foam-dried powder from freeze-dried powder; however, a thicker foam yielded a scent profile closer to that of freeze-dried powder. The findings provide fundamental data on mango foam drying, which is expected to improve processing and storage tech for local mangoes.

This study aimed to develop an optimal processing method for the production of apple-mango jelly for domestic suppliers, by analyzing the quality attributes of the jelly. According to the central composite design, a total of 11 experimental points were designed including the content of apple-mango juice (X₁), and the sugar content (X₂). The responses were analyzed including the color values (CIE Lab and color difference), physicochemical properties (water activity, sweetness, pH, and total acidity), and textural properties (hardness and gel strength). Regression analysis was conducted, except for total acidity, and showed no significant difference for all the experimental points (p<0.05). Quadratic model was derived for all responses with an R square value ranging from 0.8590 to 0.9978. Based on regression model, the appropriate mixing ratio of apple-mango jelly was found to be 31.11% of apple mango juice and 14.65% of sugar. Through this study, the possibility for developing jelly product using apple-mango was confirmed, and it is expected that these findings will contribute to the improvement of the agricultural industry.

Background: This study aimed to investigate the quality characteristics of Astragalus membranaceus Bunge leaf (AMBL) fermented with lactic acid bacteria and the applicability of its biologically active compounds. Methods and Results: An assessment of physicochemical properties such as pH, total acidity, free sugars, and isoflavonoid (calycosin-7-o-β-d-glucoside, ononin, calycosin, and formononetin) was conducted. Furthermore, the levels of antioxidant compounds, including polyphenols and flavonoids, and radical scavenging activities of the extracts using 2,2-Diphenyl-1-picryl-hydrazyl-hydrate and 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) were investigated. The calycosin content in the water extract of AMBL fermented with Leuconostoc mesenteroides increased by approximately twice as much as the control. Conclusions: These results indicate that L. mesenteroides can be used to improve biological activity through fermentation, and that AMBL can be used as a functional materials and edible resource in industrial areas.

쌀은 우리나라에서 오래 전부터 주식으로 사용되어 온 중요한 식량자원으로, 우리 식생활에서 밥이 차지하는 비중은 상당히 크며 매식사 마다 취반하는 것이 보편적 형태이다. 하지만, 취반 직후의 밥은 시간이 지남에 따라 물성이 변화하므로 이에 따라, 밥을 냉동 보존하여 적절한 방법으로 해동하면 갓 지은 밥의 조직감으로 복원이 가능하다. 또한, 건조 처리하여 열수복원 후 즉석으로 섭취할 수 있어 장기 보존 시의 품질유지를 위한 가공기술 적용이 필요할 것으로 사료된다. 이에 따라, 쌀알을 이용하여 HMR(Home meal replacement) 편의식 개발을 위한 가공적성 연구를 수행중에 있으며, 건조, 냉동, 열처리 방법과 같은 가공변수에 따라 냉동밥, 건조밥, 편의식 죽 등의 적용 특성을 분석함으로써 다양한 원료쌀 을 선택할 수 있는 기틀을 마련하여 국내 쌀 소비확대에 기여할 것으로 생각된다.
