摘要
天然蛇紋岩（Serpentinite）是一種富含鎂之矽酸鹽礦物之矽酸鹽礦物總稱，因含有金屬元素與層狀結構，因此浸水可溶出鎂離子（具有離子釋放能力）。蒜頭，是一種廣泛栽培作物，蒜頭化學組成非常豐富且有保健效能。此外，鎂與錳都是人體中重要營養素，增加蒜頭中鎂礦物質含量可穩定大蒜素不易分解或釋放；提高錳礦物質能夠促進蒜頭中多糖類代謝。本研究改質天然蛇紋岩粉末，以浸鍍及烘烤燒結條件提高蛇紋岩粉末的結晶度與離子（鎂與錳）溶出能力，進而種植鎂錳蒜頭並調查成長特性。實驗數據顯示，蛇紋岩粉末具有層狀結構，藉助烘烤燒結能夠降低雜質含量，且能提高粉末結晶度與離子釋放能力。根據粉末體表面積與離子釋出濃度數值，以400度烘烤燒結1小時的Mg-Si-Mn-O-400 粉末具有天然鎂錳離子水製備的優點。此外，鎂錳蒜頭含有鎂元素（38-43 mg/L）與錳元素（11-17 mg/L）。鎂錳蒜頭組成中含較多量大蒜腺體與硫化合物。經自然乾燥後，鎂錳蒜頭的大蒜腺體不易分解且含水率高，確認鎂錳蒜頭具高營養價值和抗氧化特性，將有助於休閒產業應用與推廣。

Abstract
Natural serpentinite is the general name of a water-containing magnesium-rich silicate mineral. Because it contains metal elements and a layered structure, it can dissolve magnesium ions when soaked in water (with its ability to release ions). Garlic is a widely cultivated root vegetable. The chemical composition of garlic is very rich and has health benefits. In addition, magnesium and manganese are important nutrients for the human body. Increasing the content of magnesium minerals in garlic can stabilize allicin, keeping it from being decomposed or released; increasing manganese minerals can promote the metabolism of polysaccharides in garlic. In this study, the natural serpentinite powder was modified, the crystallinity and ion (magnesium and manganese) dissolution ability of the serpentinite powder were improved by immersion plating and baking sintering conditions, and then the magnesium manganese garlic was planted before its growth characteristics were investigated. As the experimental data show, the serpentinite powder has a layered structure, the impurity content can be reduced by baking and sintering, and the crystallinity and ion release ability of the powder can be improved. According to the powder surface area and ion release concentration values, the Mg-Si-Mn-O-400 powder baked and sintered at 400
degrees for 1 hour has the advantage of being made of natural magnesium and manganese ion water. In addition, magnesium manganese garlic contains magnesium (38-43 mg/L) and manganese (11-17 mg/L). Magnesium manganese garlic contains more garlic glands and sulfur compounds. After natural drying, the garlic glands of magnesium-manganese garlic cannot be easily decomposed and have a high water content. It is confirmed that magnesium-manganese garlic has high nutritional value and antioxidant properties. Therefore, it will help bolster the application and promotion of the leisure industry.Keywords: serpentine, powder, garlic, sintered, ion release
