PROBLEM TO BE SOLVED: To provide a packed food product which does not cause deterioration of quality of the food product, e.g. discoloration, in heat-treating the packed food product in such a state that the food product, with a fat dispersed in water, is sealed in a container in the presence of a head space.SOLUTION: A packed food product which consists of a fat, a first emulsifier consisting of a hydrophilic emulsifier, a second emulsifier having an HLB value lower than that of the first emulsifier and, if necessary, other food materials, dispersed in water, is sealed in a container in the presence of a head space and heat-treated. A method of producing a packed food product comprises sealing a food product consisting of a fat, a first emulsifier consisting of a hydrophilic emulsifier, a second emulsifier having an HLB value lower than that of the first emulsifier and, if necessary, other food materials, dispersed in water, in the presence of a head space and heat-treating the sealed food product.COPYRIGHT: (C)2014,JPO&INPIT【課題】油脂を水に分散させた形態の食品をヘッドスペースが存在する状態で容器に密封した容器入り食品を加熱処理する際に、食品が変色する等の品質低下を生じない容器入り食品を提供する。【解決手段】油脂と、親水性乳化剤である第1乳化剤と、該第1乳化剤よりもHLB値が低い第2乳化剤と、必要により他の食品材料とを水に分散させた形態の食品を、ヘッドスペースが存在する状態で容器に密封して加熱処理を施す容器入り食品。油脂と、親水性乳化剤である第1乳化剤と、該第1乳化剤よりもHLB値が低い第2乳化剤と、必要により他の食品材料とを水に分散させた形態の食品を、ヘッドスペースが存在する状態で容器に密封して加熱処理を施すことを特徴とする容器入り食品の製造方法。【選択図】なし
