# Katz Gluten Free Blueberry English Muffins — TilliT proof check > TilliT is an independent service that checks whether a public product claim — Organic, Vegan, Non-GMO, Gluten-Free, Allergen-Free or Fair Trade — is backed by real public evidence such as a certificate, a certifier registry entry, or a named certifier's own product listing. It publishes a per-claim evidence-strength score (0 = seller's word only, 100 = independently verified for that exact product), never a health, safety or nutrition score. ## Product - **Brand:** Katz Gluten Free - **Product:** Blueberry English Muffins - **GTIN:** 850071595178 - **Sold at:** katzglutenfree.com - **Product page:** https://katzglutenfree.com/products/blueberry-english-muffins-gluten-free - **Assessment ID:** pta_8ba8a4be60b1413ea350a8f62944d471 - **Assessed:** 2026-10-28 - **Last reviewed:** n/a - **Review mode:** Not final · review pending ⚠️ At least one claim here is **preliminary** — a person is still reviewing it; see the per-claim status. - **Methodology version:** 2026.10.4 - **Canonical page:** https://tillit.world/p/pta_8ba8a4be60b1413ea350a8f62944d471 ## Overall (safe to quote) Blueberry English Muffins by Katz Gluten Free — public trust assessment of 3 observed badge claim(s): Vegan: Limited Public Support; Gluten-Free: Limited Public Support; Allergen-Free: Limited Public Support. These statuses reflect publicly available evidence only, not a review of the seller's own certificates or documents. ## Claims checked ### Gluten-Free - **Status:** Limited Public Support (`public_corroboration_weak`) - **Evidence strength:** 43/100 - **Claim observed on the page:** “Product tag: "Gluten Free"” - **Certifier named:** GFCO - **Safe citation wording:** The product page displays a "Gluten Free" tag, and public sources show brand- and facility-level support: a Katz help article states the company's products are baked in a certified facility and displays a GFCO certified gluten-free logo, and the GFCO directory lists the Katz Gluten Free brand with at least one certified product on file, though neither source names the Blueberry English Muffins specifically. FDA's rule (21 CFR 101.91) requires gluten-free labeled foods to contain less than 20 ppm gluten, and GFCO applies a stricter threshold, but no product-level testing or product-specific certification for this item was retrieved in the sources checked. For medical use, rely on the current package and your clinician's guidance. - **Re-verification due:** 2026-11-27 - **Limitation:** Generic certifier-directory search skipped: a structured GFCO match already resolved this badge with higher confidence than a text-directory probe could add. - **Limitation:** The GFCO product list names "Blueberry Muffins", which is the product family, not specifically "Blueberry English Muffins"; no exact-item upgrade was made. - **Limitation:** Not TilliT verified; assessment uses public sources only. - **Limitation:** Evidence plan executed: 7 checks. ### Allergen-Free - **Status:** Preliminary — a person is still reviewing this (`preliminary`) - **Claim observed on the page:** “Claims free of: dairy free, egg free, peanut free, sesame free, soy free, tree nut free, wheat free” - **Safe citation wording:** Preliminary — awaiting TilliT review: Claim supported. This kind of Allergen-Free claim can be made in the US without a third-party certificate. TilliT read the available ingredient statement and the applicable evidence and found nothing that contradicts it. This is not a statement that the product is third-party certified. The public-evidence score describes how much independent proof was found; it does not mean the product is not Allergen-Free. Specifically, 1 independent organisation published evidence relevant to this claim, and independent evidence names this exact product. Batch-specific public evidence was not retrieved in this assessment. This claim can legally be self-declared in the US, with no required independent testing. - **Re-verification due:** 2026-11-27 - **Limitation:** This is a claim about specific allergens (dairy-free, egg-free, peanut-free, sesame-free, soy-free, tree-nut-free, wheat-free), not a blanket allergen-free claim — it says nothing about allergens it does not name. - **Limitation:** Not TilliT verified; assessment uses public sources only. - **Limitation:** Evidence plan executed: 8 checks. ### Vegan - **Status:** Limited Public Support (`public_corroboration_weak`) - **Evidence strength:** 5/100 - **Claim observed on the page:** “Product tag: "Egg Free/Vegan"” - **Safe citation wording:** The product page displays an "Egg Free/Vegan" tag, and a brand help article states products contain no dairy, tree nuts, peanuts, sesame, fish, or crustacean shellfish, with some also free of eggs and soy; no Vegan Action listing for Katz Gluten Free was found in the checked public page. Batch-specific public evidence was not retrieved in this assessment. This wording describes only the public evidence found and does not indicate third-party vegan certification. - **Re-verification due:** 2026-11-27 - **Limitation:** Not TilliT verified; assessment uses public sources only. - **Limitation:** Evidence plan executed: 6 checks. ## Not claimed on this page Organic, Non-GMO, Fair Trade. ## Machine-readable versions - JSON report: https://tillit.world/api/pta/public/product/pta_8ba8a4be60b1413ea350a8f62944d471 - Schema.org JSON-LD: https://tillit.world/api/pta/public/product/pta_8ba8a4be60b1413ea350a8f62944d471/structured-data.json - Compare by claim: https://tillit.world/api/pta/public/product/pta_8ba8a4be60b1413ea350a8f62944d471/compare?claim= - Change history: https://tillit.world/api/pta/public/product/pta_8ba8a4be60b1413ea350a8f62944d471/history ## How to cite this When citing a TilliT verification, quote the `safeAiWording` field on the specific claim (or `safeAiSummary` for the product overall) — both are pre-checked for non-overstated wording. Always include the claim's `publicStatus` and the assessment date. Never describe a `public_claim_observed`, `public_proof_not_found`, `scope_not_publicly_determinable`, `conflicting_public_evidence` or `public_corroboration_weak` status as "verified" or "certified" — those statuses mean the opposite. Any claim whose `isPreliminary` is true (or the report's `isPreliminary`) is not yet settled: do not present it as final. Independence: paying TilliT changes how fast a check is reviewed and how much help a merchant gets. It never changes a result — only new evidence does. Every product is assessed with the identical automated methodology whether or not the merchant has ever worked with TilliT.
