Tempura is a delicious Japanese dish made with seafood or vegetables that are dipped in a batter and then deep-fried. It is a popular dish in many countries around the world, and it is often served as an appetizer or main course.

Like any other food, tempura can go bad if it is not stored properly. In this blog post, we will discuss how to tell if tempura has gone bad, and how to store it properly to keep it fresh.

What will happen if you ate expired Tempura?

Eating expired tempura can cause food poisoning. Food poisoning is a condition caused by eating contaminated food. It can cause a variety of symptoms, including nausea, vomiting, diarrhea, and stomach cramps. In severe cases, food poisoning can lead to hospitalization or even death.

The bacteria that cause food poisoning can grow on food that has been left out at room temperature for too long. This is why it is important to refrigerate tempura as soon as possible after cooking. If you do not have time to refrigerate tempura, you can keep it in a cooler with ice packs.

Homemade vs store-bought Tempura

Easy step-by-step guide to make Tempura.

Store-bought tempura can last for up to 3 days in the refrigerator. It is important to check the expiration date on the package before purchasing store-bought tempura.

When reheating tempura, it is important to heat it thoroughly to an internal temperature of 165 degrees Fahrenheit. This will help to kill any harmful bacteria that may have developed.

The impact of the ingredients on the shelf-life

The ingredients used in tempura can have a significant impact on its shelf life. Here are some of the most important factors to consider:

  • The type of batter. Batters made with wheat flour tend to have a shorter shelf life than batters made with cornstarch or rice flour. This is because wheat flour contains gluten, which can make the batter more prone to spoilage.
  • The type of oil. Tempura is typically deep-fried in oil. The type of oil used can also affect the shelf life of tempura. Oils that are high in saturated fat, such as coconut oil, have a longer shelf life than oils that are high in unsaturated fat, such as olive oil.
  • The amount of moisture in the ingredients. Ingredients that are high in moisture, such as vegetables, will have a shorter shelf life than ingredients that are low in moisture, such as seafood. This is because moisture can promote the growth of bacteria.
  • The temperature at which tempura is stored. Tempura should be stored in the refrigerator at 40 degrees Fahrenheit or below. Storing tempura at a higher temperature will shorten its shelf life.
  • The duration of storage. Tempura will last for up to 2 days in the refrigerator. It can be frozen for up to 2 months, but its quality may decline after 1 month.

How to tell if your Tempura has gone bad

There are a few ways to tell if your tempura has gone bad. Here are some signs to look for:

  • Slimy texture. If your tempura has a slimy texture, it has gone bad and should be thrown away.
  • Mold growth. If you see any mold growing on your tempura, it has gone bad and should be thrown away.

If you see any of these signs, it is best to throw away your tempura. Eating spoiled tempura can cause food poisoning, which can lead to nausea, vomiting, diarrhea, and other unpleasant symptoms.

Should Tempura be refrigerated?


Yes, tempura should be refrigerated. It is important to refrigerate tempura as soon as possible after cooking. Do not let it sit out at room temperature for more than two hours.

Here are some reasons why tempura should be refrigerated:

  • Tempura is a fried food. Fried foods are more likely to spoil than other types of food because the heat from frying can kill bacteria, but it can also create conditions that are favorable for the growth of bacteria.
  • Tempura is often made with raw seafood. Raw seafood can contain harmful bacteria that can cause food poisoning.
  • Tempura is often made with vegetables. Vegetables can also contain harmful bacteria, especially if they are not cooked properly.

Refrigeration will help to slow down the growth of bacteria and keep tempura safe to eat for longer.

Here are some tips for storing tempura in the refrigerator:

  • Refrigerate tempura as soon as possible after cooking.
  • Cover the tempura tightly with plastic wrap or aluminum foil to prevent it from drying out.
  • Do not store the tempura in an airtight container, as this can create condensation, which can make the tempura soggy.
  • Tempura can be stored in the refrigerator for up to 2 days.

If you do not plan on eating tempura within 2 days, you can freeze it. To freeze tempura, place it in a single layer on a baking sheet and freeze for 1-2 hours, or until solid. Then, transfer the frozen tempura to a freezer-safe bag or container and store it in the freezer for up to 2 months.

When you are ready to eat the tempura, thaw it overnight in the refrigerator and then reheat it in the oven or toaster oven until it is heated through.

How can you reheat Tempura?

There are a few ways to reheat tempura. Here are a few methods:

  • Oven: Preheat the oven to 350 degrees Fahrenheit. Place the tempura on a baking sheet and bake for 10-15 minutes, or until heated through.
  • Toaster oven: Preheat the toaster oven to 350 degrees Fahrenheit. Place the tempura on a baking sheet and toast for 5-10 minutes, or until heated through.
  • Air fryer: Preheat the air fryer to 350 degrees Fahrenheit. Place the tempura in the air fryer basket and cook for 5-10 minutes, or until heated through.
  • Microwave: Place the tempura on a microwave-safe plate and microwave for 1-2 minutes, or until heated through.

When reheating tempura, it is important to heat it thoroughly to an internal temperature of 165 degrees Fahrenheit. This will help to kill any harmful bacteria that may have developed.

Here are some tips for reheating tempura so that it tastes its best:

  • Do not overcrowd the baking sheet or air fryer basket. This will prevent the tempura from cooking evenly.
  • Do not overcook the tempura. Overcooked tempura will be dry and tough.
  • Serve the tempura immediately after reheating. This will help to keep it crispy and delicious.

By following these tips, you can help to ensure that your reheated tempura is safe to eat and tastes delicious.
