The Core Ingredient: 100% Corn
The main component of Argo starch is 100% pure corn. The endosperm, the starchy inner part of the corn kernel, is used. This endosperm is separated from the kernel and ground into a fine powder, which is the cornstarch. Because it is made from corn, it is naturally gluten-free. This characteristic makes it suitable for people who have celiac disease or gluten sensitivities.
The Manufacturing Process: From Corn to Cornstarch
The Argo starch company was founded in the early 20th century in the Chicago area. Although the exact process is complex, the basic steps are:
- Soaking: Corn kernels are soaked to soften them and start the separation.
- Grinding: The softened kernels are ground to separate the components like the germ and endosperm.
- Separation: The slurry goes through steps to isolate the endosperm, rich in starch.
- Drying: The endosperm starch is dried, refined, and milled into the fine powder that is Argo cornstarch.
Some consumers have concerns about genetically modified (GMO) ingredients in Argo starch, as indicated on some vendor sites. The manufacturer, ACH Food Companies, has facilities in the U.S., including one in Illinois.
Argo Starch vs. Other Thickeners: A Comparison
Comparing Argo cornstarch to other thickeners helps to understand its benefits. Different starches have different properties, affecting texture and clarity.
| Feature | Argo (Cornstarch) | All-Purpose Flour | Arrowroot Starch |
|---|---|---|---|
| Thickening Power | High | Medium | High |
| Clarity | High | Low | Very High |
| Gluten Content | Gluten-free | Contains gluten | Gluten-free |
| Best for Dairy | Excellent | Excellent | Poor |
| Cooking Method | Mix with cold liquid | Mix with fat or liquid | Low-heat applications |
| Best for Freezing | Poor | Good | Excellent |
Versatile Uses of Argo Starch in the Kitchen
Argo starch is a useful ingredient in the kitchen because of its versatility. Here are some common uses:
- Thickening Sauces and Gravies: It creates smooth, glossy sauces for stir-fries and gravies.
- Desserts: It is used in pies, puddings, and custard fillings.
- Baking: It can be combined with flour to tenderize baked goods like cakes and cookies.
- Frying: It is used to coat foods to achieve a crispy exterior.
- Glazes: It creates shiny glazes for meats and vegetables, thickening without clouding the flavor.
Health and Dietary Considerations: Is Argo Starch Gluten-Free?
Yes, Argo cornstarch is 100% pure cornstarch and certified gluten-free. This makes it a safe choice for those avoiding gluten, whether due to celiac disease or intolerance. Unlike flour, which contains gluten, cornstarch comes from the corn kernel's endosperm, which has no gluten. Its purity allows it to be used in various recipes, from thickening sauces to adding texture to gluten-free baked goods.
Handling and Storage Tips
To maintain its quality and prevent clumping, Argo cornstarch should be stored in a cool, dry place in a sealed container. This protects it from moisture, which can cause lumps. Proper storage ensures its effectiveness and extends its shelf life.
Conclusion
Argo starch is made of 100% pure corn, processed into a fine powder. It is gluten-free and a strong thickener in many cooking and baking applications. Its consistent performance has made it a trusted kitchen staple.
