Food Grade Chitin (Assay above 90%, Flake or Powder)

Cat No:CHCH-0025

Description

This premium chitin is purified from deep sea snow crab leg shell and reaches an assay above 90% with ash below 2.0%, and its heavy metal levels are well inside the limits set for food use. It is the preferred starting material for food grade and higher grades of chitosan and for glucosamine salts, and can also be used directly as a food industry intermediate.

Color	Off-white
Odor	Odorless or with a slight characteristic odor
Solubility	Soluble in strong inorganic acids with partial chain degradation
Water Solubility	Insoluble in water
Solubility in Organic Solvents	Insoluble in weak inorganic acids, alkali and common organic solvents
Moisture (Loss on Drying)	Below 10%
Ash Content	Below 2.0%
Assay / Purity	Above 90%
Particle Size	Flake or powder
Lead (Pb)	Below 2 ppm
Arsenic (As)	Below 1 ppm
Storage Temperature	Ambient, 15-25 °C
Storage Conditions	Store in a cool, dry and well-ventilated place; keep the container tightly closed and protect from moisture and direct sunlight
Allergen & Dietary Statement	Derived from crustacean shell (shrimp and crab); not suitable for shellfish-allergic consumers. Non-GMO, not irradiated
Intended Use	Raw material for further manufacturing
Target Industries	Food grade chitosan production, glucosamine production, food ingredients
Recommended Applications	Raw material for food grade and higher grade chitosan and for glucosamine salts; food industry intermediate
Handling & Safety	Handle as a fine powdered material; avoid dust formation and wear gloves, mask and eye protection
Chemical Class	Food grade purified chitin, the parent polysaccharide of the whole chitosan family
Structural Unit	beta-(1,4) linked N-acetylglucosamine chains packed into ordered alpha-chitin domains
Functional Groups	Predominantly acetamido and hydroxyl functional groups arranged along a highly ordered chain
Ionic Character	Neutral polysaccharide with no meaningful charge contribution inside food systems
Key Features	Higher assay above 90 percent to suit food grade conversion routes and tighter residue limits
Functional Benefits	Cleaner starting material improves yield, colour and residue profile in downstream food grade chitosan
Mechanism of Action	Conversion proceeds through controlled alkaline removal of the acetyl group from the C-2 amine
Typical End Products	Food grade chitosan, glucosamine salts, dietary fibre ingredients, food industry intermediates
Formulation Compatibility	Physically inert toward most food matrices because of its insolubility and high crystallinity
Preparation & Dissolution Guidance	Dispersed rather than dissolved, then processed under strong alkali for conversion to chitosan
Reactivity & Derivatization	Acid hydrolysis routes to glucosamine start most efficiently from this higher purity material
Stability Notes	Excellent dry stability; the main practical risk is moisture pickup from inadequate packaging
Usage Precautions	Keep food grade and industrial grade streams physically separated throughout plant operations
Environmental Profile	Recovered from shell waste streams and completely biodegradable at the end of its life
Analytical Methods	Assay by hydrolysis titration; moisture by loss on drying; ash content; particle size by sieve
