The Core Ingredients of Rice Crackers
At their most basic, rice crackers are a simple baked or fried snack. Their core components lay the foundation for the crispy texture and mild flavor. The primary ingredient is, unsurprisingly, rice, though the specific type can vary.
Rice
Most commercial rice crackers are made from rice flour, often derived from either glutinous rice or non-glutinous varieties like Japonica rice. The type of rice used affects the final texture. Glutinous rice, also known as sticky rice, creates a particularly light and airy cracker. Some healthier versions use whole-grain brown rice, which increases the fiber content, but many commercial brands utilize more refined white rice.
Water
Water is mixed with the rice flour to create a dough. The amount of water and the process of kneading and steaming are critical to developing the correct texture.
Starch
To achieve the signature crispness, manufacturers often add additional starches, such as tapioca starch or amylopectin, to the rice flour and water mixture. The heating process, known as gelatinization and dextrinization, breaks down these starches to create the light, puffy structure.
Salt
Salt is a fundamental ingredient, used to enhance the flavor of the cracker base.
Flavorings and Additives
While the base of a rice cracker is simple, the vast array of flavors available comes from the addition of various seasonings and additives.
Common Flavorings
- Soy Sauce: A classic Asian flavoring, soy sauce adds a savory, umami-rich taste. It is important to note that many soy sauces contain wheat, so those with gluten sensitivities must check the label for a certified gluten-free option.
- Sugar: Found in both savory and sweet crackers, sugar balances the saltiness and adds a hint of sweetness. Sources can include simple sugar or corn maltodextrin.
- Seaweed and Sesame Seeds: These are popular traditional toppings that add distinct flavor and texture.
- Chili Powder and Spices: For those who enjoy a kick, chili powder and other spices are added for heat. Garlic and ginger powders are also common.
Modern Additives
- Oils: Rice crackers are often baked, but some are fried or coated in oil for flavor and texture. High oleic sunflower oil or rice bran oil are common choices. Preservatives like soybean tocopherol may be added to maintain freshness.
- Artificial Colors: Some brands, particularly assorted oriental-style crackers, use artificial food colorings like FD&C Yellow 5 & 6 to make them visually appealing.
Health and Dietary Considerations
The ingredients in rice crackers have several implications for health and various dietary needs.
Gluten-Free Status
Rice is naturally gluten-free, so a basic rice cracker made only with rice flour and salt is suitable for those with celiac disease or gluten intolerance. However, many flavored varieties use soy sauce that contains wheat. It is crucial for anyone with a gluten-free diet to read labels carefully and look for certified gluten-free products.
Sodium Content
Seasoned rice crackers, especially those with soy sauce, can be high in sodium. Comparing nutrition labels between brands is recommended for those monitoring their sodium intake.
Whole Grains vs. Refined Grains
While some brands offer crackers made with whole-grain brown rice, most commercial versions use refined white rice. This means they are higher in carbohydrates and can cause a quicker spike in blood sugar levels. Pairing them with a protein or fiber source can help mitigate this effect.
The Rice Cracker Production Process
The journey from rice grain to crunchy cracker involves several key stages.
- Powder Production: Rice grains are milled into a fine flour.
- Dough Formation: The flour is mixed with water and kneaded into a dough.
- Shaping: The dough is flattened and cut into various shapes (circles, squares, etc.).
- Drying: The shaped pieces are carefully dried to reduce moisture content.
- Baking: The crackers are baked at high temperatures to achieve their crisp, puffy texture.
- Flavoring and Packaging: After baking, the crackers are seasoned and then packaged to preserve freshness.

Conclusion
What do rice crackers contain? The answer is more complex than it first appears. While their foundation of rice, water, and starch is straightforward, the addition of numerous flavorings, oils, and other additives creates a wide spectrum of products. For those seeking a simple, low-sodium snack, plain rice crackers are an excellent option. However, for anyone with dietary restrictions like celiac disease, or those mindful of sodium and sugar, reading the ingredient list is essential to ensure the rice cracker fits their needs. The diversity of the product, from basic and wholesome to richly seasoned, means there is a rice cracker for almost every preference, as long as you know what you are looking for.
