Expert Guide on How to Get Rid of Starch

According to a study published in the journal Nature Metabolism, high-starch foods can cause blood sugar spikes that influence appetite and energy intake. Fortunately, knowing how to get rid of starch can help with everything from achieving better cooking results to managing health and even caring for your laundry.

Quick Summary

This guide details effective techniques for removing or reducing starch in various situations, including cooking foods like rice and potatoes, adjusting dietary intake, and treating starchy residues on fabrics.

Key Points

• Rinse Before Cooking: For rice, rinsing with cold water until it runs clear effectively removes surface starch, ensuring fluffy, separate grains.

• Soak Cut Potatoes: Submerging cut potatoes in cold water for 30 minutes leaches out excess starch, leading to crispier results when frying or roasting.

• Prioritize Non-Starchy Foods: In your diet, reduce starch by favoring lean proteins, healthy fats, and vegetables like greens, broccoli, and peppers instead of grains and starchy roots.

• Use Vinegar for Laundry: To remove heavy starching from clothes, pre-soak them in a solution of warm water and white vinegar before washing.

• Refrigerate Cooked Starches: Cooling and reheating foods like rice and potatoes increases their resistant starch content, which acts like fiber and is beneficial for gut health.

• Avoid Rinsing Pasta for Hot Dishes: Rinsing cooked pasta removes the starchy coating that helps sauce cling to the noodles; only rinse for cold pasta salads.

• Leverage Enzymatic Detergents: Use a detergent with amylase enzymes for stubborn food stains on laundry, as these enzymes are designed to break down starch molecules.

How to Get Rid of Starch in Cooking

Removing excess starch from food is a common practice for improving texture and consistency in many recipes. Depending on the food and the desired outcome, different methods are effective.

Removing Starch from Rice

Excess starch on the surface of rice grains can lead to a gummy, clumpy texture. The goal of removal depends on whether you want fluffy individual grains (like for a pilaf or steamed rice) or if you are aiming to increase resistant starch.

Here are some methods for removing excess surface starch:

• Rinse Thoroughly: Place uncooked rice in a fine-mesh strainer and rinse under cold, running water. Swish the rice around with your fingers to agitate the grains. Continue rinsing until the water runs clear. This is crucial for preventing stickiness in steamed rice.
• Soak and Rinse: For brown rice or other grains with phytic acid, soaking for 30–40 minutes before rinsing can help reduce both starch and phytic acid, improving digestibility. Always drain well after soaking.
• Boil in Excess Water: For some recipes, you can cook rice in a large pot with more water than usual. After cooking, drain the excess water, which carries away some of the dissolved starch.
• Overnight Cooling (for Resistant Starch): A viral hack involves cooking rice, then cooling it in the refrigerator overnight before reheating. This process increases the amount of resistant starch, which has health benefits, making it function more like dietary fiber.

Removing Starch from Potatoes

Excess starch in potatoes can lead to soft, crumbly results when you want them to be crispy. There are several tricks to help manage this.

• Soak in Cold Water: After peeling and cutting potatoes, place them in a bowl of cold water for at least 30 minutes. This allows the starch to leach out into the water. For best results, change the water periodically until it remains clear.
• Blanching: For recipes like french fries or hash browns, blanching can be highly effective. Boil the cut potatoes for 2-4 minutes, then immediately plunge them into an ice bath to stop the cooking process. Drain and pat dry before cooking.
• Use Waxy Varieties: Some potato varieties, like Yukon Gold or red potatoes, are naturally lower in starch (waxy) than starchy varieties like Russets. Choosing a waxy potato is an easy way to reduce starch from the start.

How to Reduce Dietary Starch

A low-starch diet can be beneficial for managing blood sugar, promoting weight loss, and improving digestive health. Reducing starch is typically achieved by shifting your food choices toward lean proteins, healthy fats, and non-starchy vegetables.

Here are some ways to reduce dietary starch:

• Substitute with Low-Starch Alternatives: Swap high-starch foods like rice and pasta for alternatives such as cauliflower rice, zucchini noodles, or quinoa.
• Emphasize Non-Starchy Vegetables: Increase your intake of vegetables like leafy greens, broccoli, bell peppers, and asparagus. These are nutrient-dense and high in fiber, which helps you feel full.
• Focus on Protein and Healthy Fats: Incorporate more foods rich in protein (meat, fish, eggs) and healthy fats (avocado, olive oil) to increase satiety and control appetite.
• Understand Resistant Starch: As mentioned for cooking rice and potatoes, cooking and cooling starchy foods can increase resistant starch, which is not digested and helps with gut health. This means you don't always have to eliminate these foods entirely but can prepare them strategically.

How to Remove Starch from Clothes

Starch is often used in laundry to stiffen fabrics for a crisp, professional look. However, sometimes you need to reverse this process.

• Regular Wash Cycle: For light starching, simply running the garment through a normal wash cycle with your standard detergent is often enough.
• Pre-Soak with Vinegar: For more heavily starched items, a pre-soak is highly effective. Add ¼ cup of white vinegar to warm water and let the clothes soak for at least 30 minutes or overnight before running a normal wash cycle. The vinegar helps break down the starch bonds.
• Use Fabric Softener: For general stiffness, adding liquid fabric softener to the rinse cycle can help loosen fabric fibers and remove residual starch.
• Enzymatic Detergent: For stubborn food stains that contain starch (like sauces or dressings), use a laundry detergent with amylase enzymes, which are formulated to break down starch molecules.
