PROBLEM TO BE SOLVED: To predict a blending amount of bacteriostatic required for bacteriostasis, based on a specific compound amount in a lactic fruit juice drink.SOLUTION: The production method comprises: a regression plot generation step for generating a regression plot indicating at least a relationship between lactic component density and microbe growth characteristic, based on a result in which microbe is inoculated to plural kinds of lactic fruit juice drinks having plural different density parameters including at least lactic component density and bacteriostatic density, and after inoculation of the microbe, the lactic fruit juice drinks including the microbe are cultivated and a function generation step for generating a bacteriostatic density function for determining the bacteriostatic density from variables including at least the lactic component density, based on the regression plot.COPYRIGHT: (C)2015,JPO&INPIT【課題】乳性果汁飲料中の特定成分量から静菌に必要な静菌剤の配合量を予測できるようにする。【解決手段】本発明は、同一原料からなり、少なくとも乳成分濃度及び静菌剤濃度を含む複数の濃度パラメータが異なる複数の乳性果汁飲料に微生物を接種し、接種後の微生物入り乳性果汁飲料を培養した結果から、少なくとも乳成分濃度と微生物の増殖特性との関係を示す回帰プロットを生成する回帰プロット生成工程と、この回帰プロットに基づいて、少なくとも乳成分濃度を含む変数から静菌剤濃度を求める静菌剤濃度関数を生成する関数生成工程とを含む。【選択図】図3
