以往人們所追求的僅止於吃的飽，隨著國民生活水準提昇，許多國家的消費型態都面臨了轉變，使得消費者對於食品衛生安全的關心日益增加，然而食品中毒在日常飲食或旅遊中都容易發生，食物來源的安全性是造成食品中毒的主要原因之一，因此衛生署多年來強調「源頭管制」的觀念。在餐廳中能掌控來源的人員即是採購人員，近年來旅館演變為接待當地居民大宴小酌的場所，甚而餐飲收入超越客房收入，可知餐飲對於旅館的重要性是益加重要的，但關於食品安全的研究少有探討餐廳採購的部分，而餐廳卻是食品中毒易發生的場所，因此有必要進一歩研究影響旅館的餐飲採購人員採購安全食品的因素為何。
本研究引用 Ajzen 的「計畫行為理論」，以「態度」、「主觀規範」與「知覺的行為控制」三項變數探討非個人意志所能完全控制的組織採購行為－旅館餐飲採購人員採購安全食品行為。研究對象為台灣全數國際觀光旅館以及一般觀光旅館之採購人員，另依北部、中部、南部、東部以及離島之樣本採用分層比例抽樣法抽出一般旅館中之採購人員，詢問旅館接受調查的意願後，共郵寄出268家共363份問卷，有效的回覆問卷為198份。本研究採用SPSS以及結構方程模式(SEM)分析採購人員採購安全食品的行為，結果如下：(1) 餐飲採購人員採購安全食品的行為意向與行為之間呈現顯著正相關；(2) 餐飲採購人員對採購安全食品的態度、主觀規範與知覺行為控制均正向影響採購安全食品的行為意向，其中以「主觀規範」對行為意向的影響最大，「知覺行為控制」次之，「態度」對行為意向的影響最小；(3) 利益關係人對主觀規範影響以「主管」、「同事」以及「股東」為主要影響因素；(4) 餐飲採購人員對採購安全食品的知覺行為控制主要影響因素有「自我效能」以及「便利性條件」，其中自我效能的影響力較便利性條件大。
