Nima Testing: Can, When to Use Caution, and Can't Test

Nima is designed to give you additional information to help you feel more confident before eating. It’s is designed to test ready-to-eat food. When testing, smaller food particles will always make testing easier so crushing, ripping, or fine chopping food is likely to result in less test errors.

This information on this page will help you when doing Nima testing: what foods you can test, when you should use caution (or take extra steps), and items that can’t be tested using Nima.

Can Test

We have already tested numerous foods with Nima. Foods you can test include:

  • Soups
  • Packaged goods
  • Sauces
  • Pizza
  • Salads
  • Dressing
  • Muffins
  • French fries
  • Noodles
  • Cookies
  • Meat balls
  • Cereal
  • Tortilla chips

Cannot Test

Nima Testing: You can't test fermented foods, alcohol, or vinegar with Nima

Fermented foods/drinks

Soy sauce, beer, kombucha, yogurt, sauerkraut, kimchi

The fermentation process breaks apart the gluten molecules and renders them unable to be detected with the chemical process. Since Nima can’t detect the protein, Nima may still display a smile even if there is hydrolyzed gluten present. When testing a sample which includes these foods (soy sauce for example), Nima will still pick up any gluten present in other foods included in the sample.


liquor, wine

Alcohol is distilled and will not result in an accurate test.


We cannot detect correctly. Pure vinegar is not compatible with the test. Result will be “Gluten Found” even if if there is no gluten.

Exception: If you test a salad dressing with vinegar and gluten is found, the salad dressing is likely contaminated. If it returns a smiley face, the salad dressing is likely safe.

Use Caution

Nima Testing: When to use caution with testing specific items including hard foods, intensely colored foods, gummy foods, high fat foods, very dry or powdery foods, and thick or dense foods.

Hard foods

Dried beans, uncooked pasta, frozen peas, jerky, charred meat, suckers, frozen ingredients

These foods make it extremely difficult to close the capsule and can cause damage to Nima. Remember: If it’s hard to chew, it’s hard to test. These foods need to be softened, ground, finely chopped or defrosted prior to testing.

Intensely colored foods

kool aid powder, bright candies, beets, coffee grounds, food dye

Intense coloring can hinder the test reading. These items should be diluted or tested in small quantities.

Gummy food

Gelatin candy, anything containing high amounts of xantham gum or guar gum, taffy, bubble gum

These foods by their nature are extremely thick and prone to stickiness which means they can easily clog the capsules even if samples are small. Use discretion when testing these foods. Samples may need manipulated prior to testing.

High fat foods

ice cream, heavy cream, chocolate, butter, non homogenized milk & salad dressings

If too much high fat food is put into a capsule, the fat will clog the capsule and prevent the test from completing. Nima will display an error if this happens. To lessen this issue, keep samples of these foods small – less than a pea sized amount. If liquid, do not overfill the capsule to the point where the internal teeth are covered.

Very dry or powdery foods

Pure flour, cinnamon, corn starch, dried spices, seasoning packets

If too much dry or powdery food is put into a capsule, the food will clog the capsule and prevent the test from completing. Nima will display an error if this happens. To lessen this issue, keep samples of these foods extremely small. 1/4 teaspoon or less.

Thick or dense foods

Oatmeal, syrup, honey, meat

These textures make it difficult to close the capsule and are prone to clogging the system. When testing, food should be softened or samples made extremely small, 1/4 teaspoon or less.

Never Validated

Non food items

makeup, medication

Nima has not been developed to test non food substances. Our testing has been limited to food items so we cannot make claims around the accuracy of test results.

Exception: soap and anything containing surfactant will not produce an accurate result. These items should not be tested.

Carbonated Drinks

soda, colas, sparkling waters, and the like
