Abstract

The present application relates to a method for the preparation of an instant food and an instant food prepared according to same, wherein even when the instant food is prepared using raw ingredients and liquid sauces that are susceptible to microbial contamination or difficult to sterilize, the amount of microorganisms in the prepared instant food is lower than a threshold value, and thus a sufficient sterilization effect can be achieved, and the problem of reduced quality that may cause due to strict sterilization does not occur, and thus an instant food having excellent texture and taste can be provided.

First claim

1 . A method for the preparation of instant food, comprising:
filling solid raw ingredients into a container; sterilizing the solid raw ingredients filled in the container with pressurized steam in a vacuum state; liquid-sterilizing liquid sauces by spraying steam directly on the liquid sauces; adding the sterilized sauces to the sterilized raw ingredients; sealing the container added with the sterilized sauces; and heating the sealed container at a temperature of 90° C. to 125° C. for 10 to 25 minutes.

2 . The method for the preparation of instant food of claim 1 , wherein the solid raw ingredients have the number of microorganisms of 10 2 cfu/ml to 10 8 cfu/ml in the raw ingredients before sterilization.

3 . The method for the preparation of instant food of claim 1 , wherein the solid raw ingredients comprise at least one selected from the group consisting of grains, beans, mushrooms, root and tuber crops, bulbs, seasoned vegetables, fruits/seeds, meats, fish, and eggs.

4 . The method for the preparation of instant food of claim 1 , wherein the sterilizing of the solid raw ingredients is performed with steam at 120° C. to 140° C. for 1 minute to 10 minutes.

5 . The method for the preparation of instant food of claim 1 , wherein the sterilizing of the solid raw ingredients is performed by repeatedly contacting the solid raw ingredients 5 to 10 times with steam at 140° C. to 155° C. for 3 seconds to 10 seconds.

6 . The method for the preparation of instant food of claim 1 , further comprising immersing the solid raw ingredients in water, before filling the solid raw ingredients in the container.

7 . The method for the preparation of instant food of claim 1 , wherein the liquid-sterilizing of the liquid sauces is performed for 6 to 8 minutes by directly spraying steam at 130° C. to 140° C. to the liquid sauces.

8 . The method for the preparation of instant food of claim 1 , wherein the liquid-sterilizing of the liquid sauces is performed using a Direct-Steam Injection (DSI) sterilization device.

9 . The method for the preparation of instant food of claim 1 , wherein the viscosity of the liquid sauces is 0 to 2,000 cp.

10 . The method for the preparation of instant food of claim 1 , wherein the sugar content of the liquid sauces is 0 to 60 brix.

11 . The method for the preparation of instant food of claim 1 , wherein the liquid sauces have the number of microorganisms of 10 2 CFU/ml to 10 8 CFU/ml before liquid-sterilization.

12 . The method for the preparation of instant food of claim 1 , wherein a cooking step is not included.

13 . The method for the preparation of instant food of claim 1 , wherein heat of 105° C. or higher is not applied before the sealing step after the sterilizing of the solid raw ingredients.

14 . The method for the preparation of instant food of claim 1 , wherein a temperature of 104° C. or lower is maintained before the sealing step after the sterilizing of the solid raw ingredients.

15 . The method for the preparation of instant food of claim 1 , wherein the number of microorganisms in the solid raw ingredients measured after the heating step is 0 cfu/ml.

16 . An instant food prepared by the preparation method according to claim 1 .
