The procedure of manufacturing skin care product by fermentation of crops with hot spring water includes the following steps. Prepare a first culture fluid: mix a grinded crops and a bicarbonate hot spring water at a weight ratio of 3-10:90-97, and sterilizing it to form 1L of a first culture fluid. Prepare a second culture fluid: take 10mL of the first culture fluid with 0.2g of lactobacillus for culture in 24 hours to form a second culture fluid. Fermentation: add 3mL of the second culture fluid into the remainder of the first culture fluid for fermentation in 30 degrees Celsius, 125 rpm, and 48 hours to form a first fermentation fluid. Separate: centrifuge and filter the first fermentation fluid to form a second fermentation fluid.一種溫泉水與農作物醱酵保養品製程,包含以下步驟:製備第一培養液:將一農作物碾製粉碎後與一碳酸氫鹽溫泉水以重量比3~10:90~97的比例混合後進行滅菌並放置至室溫,以獲得1公升的一第一培養液;製備第二培養液:取10毫升的該第一培養液,加入0.2克的乳酸菌進行24小時的培養,以獲得一第二培養液;醱酵:取3毫升的該第二培養液加入剩餘的該第一培養液於溫度30℃、轉速125rpm的條件下進行醱酵48小時,以獲得一第一醱酵液;分離:對該第一醱酵液進行離心與過濾,以濾取一第二醱酵液。10‧‧‧農作物20‧‧‧溫泉水30‧‧‧第一培養液40‧‧‧乳酸菌50‧‧‧第二培養液60‧‧‧第一醱酵液70‧‧‧第二醱酵液
