마이크로웨이브 진공건조로 생산된 마늘, 고추 분말의 품질특성

초록

This study was conducted to compare and characterize the quality of garlic and chili pepper powders prepared by hot air drying (HD), freezing drying (FD), and microwave vacuum drying (MVD) methods. There was no significant difference in proximate analysis according to drying methods. The pH of HD dried garlic and chili pepper powder was 6.30 and 5.02 respectively, which were significantly lower than that of the MVD. The solubility of garlic powder was highest for FD, while the FD and MVD showed higher solubility of chill pepper powder. Both samples showed significantly lower values of vitamin B 1 and B 2 for HD and significantly lower values of vitamin C for MVD. There was no difference in the mineral contents of garlic powder according to the drying methods and the P, Mg, Mn, Cu, and Zn values of chili pepper powder were lowest for FD. The cohesiveness of HD powder was significantly higher in garlic powder, while the cohesiveness of MVD powder was significantly higher in chili pepper powder. Sensory evaluation showed no significant difference in characteristics when dry powder was applied to cooked food. ? 2018, Korean Society of Food Science and Nutrition. All rights reserved.
