雙波段光學系統應用於起雲劑檢測

摘要起雲劑雖然為食品添加劑，但商人常為了賣相好看或增加口感，導致在某些飲品中加入過量的起雲劑。合格含量的起雲劑人體是可以正常代謝的，但如過量攝取或長期食用的話，輕則造成肥胖、脂肪肝，重則會導致血管阻塞、中風、心陳代謝症候群、血栓等心血管疾病。本論文是研究人們日常生活中的飲品、食品或是添加物中是否含有過量的 Cloudy agent(起雲劑)。本研究是以純水當作飲品，加入不同體積市售的高倍數起雲劑(蒸餾水、辛烯基丁二酸鈉澱粉、椰子油、70% D-山梨醇液、丙二醇、無水檸檬酸多種食品添加物混合製成)充分混合後，再利用紅外線光譜儀進行檢測。此兩個階段檢測的標準皆是在以純水(飲品)來校正後，再依光譜儀中光線在每一段頻譜的穿透強度中找出特定波長，並在此特定波長下利用偵測透光度計算後，代入線性回歸公式去找出起雲劑濃度，並在以自製的雙波段光感測器檢出後取得雙波段的驗證值，並設計一套簡易電路來呈現，讓消費者可以快速的知道添加的劑量，避免讓身體陷入惡性的循環。

Abstract This thesis proposed the clouding agent is a food additive, traders in order to pursue a better look or increase their taste to add excessive clouding agents to certain beverages. Appropriate amount of clouding agent can be normally metabolized, However an excessive intake or long-term consumption will cause obesity, fatty liver, even lead to blood vessel obstruction, stroke, cardiovascular syndrome, thrombosis and other cardiovascular diseases. This thesis uses an infrared spectrometer to detect whether people’s daily drinks, foods, or additives contain excessive Cloudy agent. In this study, pure water was used as a drink, and various commercially available high-strength clouding agents (a gum arabic, emulsifier, sunflower oil, palm oil, and other food additives were mixed together) were mixed and examined by an infrared spectrometer to conduct the test. The two stages of detection standards are all corrected by pure water (drinks), and then the specific wavelength is found in the penetration intensity of each spectrum according to the light in the spectrometer, and the detected light is used at the specific wavelength. After the transparency is calculated, a linear regression formula is used to find the concentration of the clouding agent, and a dual-band verification value is obtained after being detected by a self-made simple spectrometer, and a set of simple circuits is designed to present it so that the consumer can quickly understand the dosage of cloudy agent. Do not allow the body to fall into a vicious circle.
