The purpose of the present invention is to maintain the activity of an
enzyme while reducing proliferation of microorganisms that cause food deterioration in a state where the
enzyme is dissolved in water. The present invention provides a food composition that satisfies all of the following requirements (a)-(d). (a) The
moisture content in terms of wet
mass is 20
mass% or more. (b) The pH at 20°C and 1 atm is more than 4.0. (c) The titratable acidity of the food composition when measured by a measurement method A is 0.1
mass% or more. Measurement method A 10 g of the food composition is accurately collected and diluted 10-fold with
ion-exchanged water, 0.08 ml of a 3.1%
phenolphthalein solution serving as an indicator is added to the diluted solution (100 g), the resulting solution is neutralized by
titration with a 0.1 mol / L
sodium hydroxide liquid having a known
titer, and the titratable acidity is determined by the following formula. Titratable acidity (mass%) of food composition={(60.05×0.1×F×V)×100} / {collection quantity (10 g)×1000} 60.05: Molecular weight of
acetic acid 0.1:
Molar concentration (mol / L) of
sodium hydroxide solution F:
Titer of 0.1 mol / L
sodium hydroxide solution V:
Titration amount (mL) of 0.1 mol / L
sodium hydroxide (d) The following requirements (i) and / or (ii) are satisfied. Requirement (i) The following formula is satisfied: 4Y+X≥10 (provided that X≥3 and Y>0.03 are satisfied), where X g represents the amount of sodium
chloride equivalent per 100 g of water of the food composition, and Y g represents the content of non-dissociated
acetic acid per 100 g of water of the food composition. Requirement (ii) The amount of sodium
chloride equivalent per 100 g of water of the food composition is 3.0 g or more, and the
ethanol content per 100 g of water of the food composition is 8.0 g or more.
