TEXTURE & STABILITY

Carrageenan CGN

A seaweed-derived hydrocolloid family used to design gelation and texture.

INGREDIENT OVERVIEW

What this ingredient
can help you explore.

Carrageenan is a hydrocolloid family, not a single interchangeable texture grade. Name the type and whether the offer is a single material or a formulated blend.

Also known as: CGN · Carrageenan gum

Kappa, iota and lambda carrageenan differ in gel behavior. Type, blend composition, ionic conditions and heat history influence the result; a family name is not a gel grade.

APPLICATION SCREENING

Where it may fit.

These are technical starting points, not finished-product performance or use authorizations.

Dairy systems: assess protein interaction and stabilization.

Desserts: compare gel strength, elasticity and syneresis.

Prepared foods: test texture with the full salt and protein system.

QUALIFICATION

Questions worth asking
before approval.

START HERE

Is the target a firm gel, elastic gel or viscosity without gelation?

01
State the carrageenan type and blend composition.
02
Define gel or viscosity test method, ions and temperature.
03
Validate sensory and storage behavior in the finished food.

GRADE & SPECIFICATION

Key parameters to confirm.

Distinguish kappa, iota and lambda descriptions, refinement/process identity and blend components. Gel or viscosity results must be compared under the stated ionic and temperature conditions.

These are procurement questions, not a supplied specification. Units below indicate reporting context, not acceptance limits. Compare the current grade, source, document revision and test method before agreeing values.

If columns extend beyond the frame, scroll the table horizontally.

Key parameters to confirm — Carrageenan
Parameter	What to request	Units or test context	Why it matters
Type and composition	Declared carrageenan type, process identity and blend components	Source definition and composition statement	Do not treat different materials or blends as one grade.
Gel characteristics	Gel or texture method where relevant	Method-defined force units; recipe, ions and temperature	A gel result depends on the test system and preparation.
Viscosity	Solution preparation and measurement conditions	mPa·s or cP; concentration, °C and settings	A viscosity figure does not describe every gel behavior.
Particle profile and insolubles	Particle and insolubles methods	Sieve/µm and stated insolubles basis	Evaluate dispersion, handling and source acceptance.
Moisture and microbiology	Relevant criteria and methods for the intended grade	% and defined microbiological units	Compare the record with the exact accepted material.

Describe the gel and food matrix

Describe the system: Give the protein and salt system, desired firmness/elasticity or viscosity, heat/cooling process, storage and the type or blend currently used.

Observe in a controlled trial: Compare gel setting, texture, liquid separation and sensory behavior through processing and storage. Do not transfer a gel-strength result from one test recipe to a different food as a guarantee.

A trial informs selection for that material and process; it is not a guarantee for a different grade or future batch.

PURCHASING QUESTIONS

CGN: what to ask next.

Is “carrageenan” enough to specify a purchase?

Include type, process identity, blend composition and the required gel or viscosity method. A family name cannot establish the behavior of a particular grade.

Can I compare gel-strength numbers from two suppliers?

First compare recipe, ions, preparation, temperature, instrument and result units. Without these, different numbers may reflect different methods rather than equivalent materials.

What information helps assess a dairy application?

Describe the protein/mineral system, heat treatment, cooling, storage and desired texture. Identify the current material and whether the objective is a gel or stabilization without that texture.

Packaging, handling & ordering

Include volume, delivery destination and required timing in the inquiry. Ask about available pack formats, minimum order, sample terms and transport arrangements for the specific offer. Confirm storage instructions, shelf life and label details against the proposed source’s current records.

DOCUMENT REQUEST

Request documents for CGN.

State the grade, source if known, food application, destination market and purpose. Ask about Current type/blend specification, gel or viscosity test methods, composition information and representative COA; confirm availability. Availability and permission to share must be confirmed for the proposed supply. Certificates must match their own entity, site and scope.
