PURPOSE:To produce a glyceride useful in the field of food and medicine, etc., as a surfactant, at a practical rate of production without causing the by- production of free fatty acid, by carrying out the glycerolysis reaction of an oil or fat in the presence of a specific lipase as a catalyst while adjusting the water-content of the reaction system. CONSTITUTION:The objective mono- and diglyceride can be produced by charging oil and fat and glycerol in a reactor at a weight ratio of preferably 1:(2-5) and carrying out a glycerolysis reaction in the presence of preferably 0.5-3% water (based on the glycerol) and optionally Ca ion usually at 25-70 deg.C using a specific lipase which proceeds the glycerolysis reaction at a specific water- content without producing free fatty acid (e.g. lipase produced by Pseudomonas fluorescens).
