中文摘要 | 結合連續性蒸氣滅菌器的數學模式和營養素的變性模式,來探討在連續性蒸氣滅菌器中,液體及不同粒徑的懸浮顆粒的溫度分布、滅菌效果及營養素的變性。在本文中共探討三種不同的營養鹽,維生素B1、維生素B12及β胡蘿蔔素的變性關係,同時也探討殺菌溫度對殺菌效果及營養素變性的影響。在這三種營養素中,維生素B1受到溫度的影響最大,在滅菌程序中,其最高可達36%的變性。殺菌程序的滯留時間、殺菌力及營養素變性三者間的互動關係在本文中也深入的探討。 |
英文摘要 | This study combines the derived mathematical models with the denaturation of nutrient's model to calculate the temperature distribution, the level of the sterility and the denaturation of nutrients for the liquid medium and the different radii of carrot particles in the continuous steam injection sterilizer. The denaturation of three different kinds of nutrients, vitamin B₁, vitamin B[feba] and beta - carotene is also discussed. The effects of sterilization temperature on the sterilization and the denaturation of nutrients for the various particle sizes and nutrients are also investigated. According to those results the cooling section is a controlling step in the sterilization process for the radius of the carrot particle exceeding 6mm. Among these nutrients, vitamin B₁ is most sensitive to the high temperature. By cumulatively considering residence time in the sterilization process, the level of sterility, the nutrient remaining and economic point of view, the optimum ranges of sterilization temperature are from 140℃ to 150℃. |
