The Art of Crafting Mimi Shrimp Crackers: A Look Inside the Production Process

Mimi shrimp crackers are a beloved snack across Asia, known for their light, crispy texture, irresistible umami flavor, and iconic tiny size. While enjoying a handful of these crunchy treats, have you ever wondered how they are made? The production of Mimi shrimp crackers is a fascinating blend of traditional flavor and modern food engineering. Here’s a step-by-step look at the typical industrial manufacturing process.

Étape 1 : Préparation des ingrédients et mélange

The journey begins with the careful selection of raw materials. The primary ingredients include:

• Starch Base: A combination of tapioca starch and wheat flour is commonly used. Tapioca starch is key as it expands beautifully when heated, creating the characteristic airy texture.
• Shrimp Seasoning: This is the soul of the cracker. Dehydrated shrimp powder, salt, sugar, monosodium glutamate (MSG), and other natural or artificial shrimp flavorings are precisely measured to achieve the perfect savory taste.
• L'eau : Acts as the binding agent to form a dough.
• Cooking Oil: Palm oil or vegetable oil is used both in the dough and for spraying later.

These ingredients are loaded into a large industrial mixer. They are blended into a smooth, uniform, and slightly moist dough. The consistency is crucial—it must be pliable enough for the next stage but not too wet.

Step 2: Cooking and Gelatinization

The mixed dough is then transferred to a cooking extruder. This machine performs a critical step called starch gelatinization. The dough is subjected to high heat and pressure as it is pushed through the extruder barrel. This process cooks the starches, making them soluble and ready to expand.Mimi Shrimp Crackers making machine

Step 3: Shaping and Forming

At the end of the extruder barrel is a die—a metal plate with tiny holes. As the hot, gelatinized dough is forced through these small holes, it emerges in the shape of thin, short strands or ribbons, which gives the crackers their classic “stick” or “tube” shape. As the pressurized dough exits the die into the regular atmosphere, it instantly puffs up slightly due to the rapid expansion of steam within the dough.

Step 4: Pre-Drying

The soft, formed crackers are now too moist to be packaged. They are conveyed through a pre-drying oven, where warm, dry air circulates around them. This stage reduces the moisture content significantly, setting their shape and making them hard and brittle. At this point, they are semi-finished products known as “half-products” or pellets.

Step 5: Frying or Baking

This is the stage where the crackers get their final crispy texture. There are two primary methods:

1. Frying (The Traditional Method): The half-products are passed through a bath of hot oil (typically palm oil) for a short time. The remaining moisture inside instantly turns to steam, causing the crackers to expand dramatically into their final light and porous form. This method yields a richer flavor and a very crispy texture.
2. Baking (A Health-Conscious Alternative): To produce low-fat or “baked” versions, the half-products are sent through a high-temperature oven instead of an oil bath. Hot air causes a similar expansion, though the texture can be slightly less crunchy compared to the fried version.Mimi Shrimp Crackers making machine

Step 6: Seasoning

After expanding, the crackers travel on a conveyor belt through a rotating drum, often called a seasoning tumbler. A fine mist of oil is sprayed onto the hot crackers to help the seasoning adhere. Then, a precise blend of powdered seasoning—containing additional shrimp powder, salt, and sugar—is evenly dusted over them as they tumble, ensuring every piece is perfectly flavored.Mimi Shrimp Crackers making machine

Step 7: Cooling and Quality Control

The hot, seasoned crackers are cooled to room temperature to stabilize their texture. They then pass through metal detectors and visual inspection systems to ensure there are no foreign materials and that the color and shape are consistent. Any broken or misshapen crackers are removed.Mimi Shrimp Crackers making machine

Step 8: Packaging

Finally, the crackers are funneled automatically into their distinctive colorful packaging. The bags are flushed with nitrogen gas before sealing. This process removes oxygen, which prevents the crackers from becoming stale and protects them from rancidity, ensuring a long shelf life and maintaining their signature crunch.Mimi Shrimp Crackers making machine

From a simple blend of starch and seasoning to the iconic snack enjoyed by millions, the production of Mimi shrimp crackers is a remarkable example of efficient and precise food manufacturing. The next time you open a bag, you can appreciate the complex engineering behind each delightful, crunchy bite.
