During summer, high temperatures can easily spoil food ingredients.

 

Meat and Fish: How to Maintain Freshness and Check for Spoilage

How to Maintain Freshness

• Refrigeration and Freezing: Meat and fish should be refrigerated or frozen immediately after purchase. Keep them at below 4 degrees Celsius for refrigeration and below -18 degrees Celsius for freezing.
• Proper Packaging: Store meat and fish in airtight containers or vacuum-sealed packaging to minimize contact with air and slow down spoilage.
• Regular Checks: Regularly check the temperature of your fridge and freezer, and periodically inspect the condition of stored food ingredients.

How to Check for Spoilage

• Smell: Spoiled meat emits a sour smell, and fish emits a strong fishy odor.
• Texture and Color: Spoiled meat has a sticky surface and changes color. Chicken turns dark, while pork and beef turn white on the surface. Spoiled fish lacks elasticity and becomes mushy when thawed.
• Packaging Condition: If a vacuum-sealed meat pack is swollen, it indicates spoilage.

 

Grains: How to Maintain Freshness and Check for Spoilage

How to Maintain Freshness

• Dry Storage: Store grains such as rice in a dry place without moisture. Moisture can lead to mold growth.
• Use Airtight Containers: Store grains in airtight containers to block air and moisture.
• Regular Ventilation: Regularly ventilate the storage area to prevent moisture buildup.

How to Check for Spoilage

• Color of Wash Water: If the water used to wash rice is dark or blue, it indicates mold growth.
• Smell: Moldy grains emit a peculiar musty odor.

• Quick Consumption After Opening: It is best to consume dairy products quickly after opening. Especially, milk should be consumed within 3-5 days after opening.

How to Check for Spoilage
