Hidden in plain sight

Unclean ingredients rarely say “pork.”

They hide behind ordinary names on food labels, vitamin bottles and pharmacy boxes. These are a few that Tahor watches for.

“Gelatin”

Usually pig skin

Boiled down from skin and bones. Labels rarely name the animal unless it’s beef or fish.

Gummies · marshmallows · softgels
“Natural casing”

Often pig intestine

A beef hot dog can still be stuffed into a pork casing, listed in small print.

Hot dogs · sausages · links
“Carmine”

Crushed insects

A red dye made from cochineal bugs. Scripture permits only certain locusts.

Red candy · yogurt · drinks
“Magnesium stearate”

Plant or animal fat

A filler in most pills. Usually from vegetable oil, but it can come from beef or pork fat.

Tablets · vitamins · capsules
“Glucosamine”

Usually shellfish

Most is made from shrimp, crab and lobster shells unless the label says otherwise.

Joint supplements
“Mono- and diglycerides”

Plant or lard

Emulsifiers usually made from soybean or palm oil, but they can come from animal fat.

Bread · ice cream · peanut butter
“Oyster extract”

Shellfish

Oyster sauce and clam juice turn up in sauces, soups and seasonings.

Stir-fry sauce · chowder · seasoning
“L-cysteine”

Feathers, hair or pig bristle

A dough conditioner in some breads. It can be synthetic or animal derived.

Bagels · rolls · pizza dough

How it works

Clear answers, with the reason behind every one.

Tahor never just says “bad.” Every flag shows what it found on the label, why it matters, and the Scripture behind it.

Scan, search or snap

Scan a barcode, type a name or drug code, paste an ingredient list, or photograph the label when a product isn’t in any database.

Checked against Scripture

Every ingredient is matched against the clean and unclean animals of Leviticus 11 and Deuteronomy 14, plus the hidden names they go by.

Verify and find alternatives

Ask the maker with a ready-made message, record what they say, and see similar products with clean ingredient lists.

ContainsThe label names something unclean, or its source was confirmed unclean.
May containAn ingredient could come from an unclean animal and the label doesn’t say which.
Clean · verifiedEvery questionable ingredient has a confirmed clean source.
No flags foundNothing matched, but no one has personally verified it yet.

What Tahor checks

The standard comes from the Torah.

Tahor is built for Torah-keeping believers: Hebrew Roots and Messianic families, Jewish households, and anyone who keeps the clean and unclean food laws. It flags pork and shellfish, but it is not an allergy tool: it can miss allergens, so people with food allergies should rely on the package and their doctor.

Land animalsMust chew the cud and have a fully split hoof.Leviticus 11:2–8
Water creaturesMust have both fins and scales.Leviticus 11:9–12
BirdsBirds of prey and scavengers are unclean.Leviticus 11:13–19
Insects and creeping thingsOnly certain locusts are permitted.Leviticus 11:20–31
BloodNever to be eaten, from any animal.Leviticus 17:10–14
