Claim:
1. A method for producing a lecithin or lecithin preparation having resistance to heat discoloration comprising: step 1: dispersing a lecithin in a dispersion medium to prepare a lecithin dispersion and adjusting the acid value of the lecithin dispersion, wherein the lecithin dispersion is prepared by using an oil or fat as the dispersion medium; step 2: bringing the obtained lecithin dispersion by the step 1 into contact with an adsorbent; and step 3: removing the adsorbent from the lecithin dispersion after the step 2, wherein the adjusting the acid value is performed by addition of an acid to the lecithin dispersion, and wherein the acid is one or more free fatty acid selected from the group consisting of caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, arachidic acid, palmitoleic acid, oleic acid, linoleic acid, α- and γ-linolenic acid, erucic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, and tetracosa tetraenoic acid.
