Definitions
- Galactomannans are nonionic polysaccharides extracted from the albumen of legume seeds of which they constitute the reserve carbohydrate. They are especially known and used as a texture agent and in particular for their viscosifying, thickening, stabilizing, water-retaining, and film-forming properties. Among the most widely used are guar gum, locust bean gum, and tara gum.
- polysaccharides are all the more advantageous because, by their nature, they are compatible with other compounds and therefore can be used in combination with these to produce synergistic effects, inter alia, in terms of texture.
- locust bean gum in combination with xanthan gum can lead to gels of different strengths and more or less elastic consistencies.
- type mesh 200 that is to say a powder having no particles greater than 80 mesh and having at most 60% by mass of smaller particles at 200 mesh, and
- the powder can be used as it is or after treatment with suitable enzymes such as, for example, alkaline, acidic and / or neutral proteases; of the
- the residence time is variable and will of course depend on the desired viscosity and the operating conditions, in particular the cooking-extrusion apparatus used, the screw speed and the feed rate. In general, it is less than 1 minute.
- the product thus extruded can undergo another or possibly several other passages in the cooker-extruder.
- a twin-screw extruder is used.
- the following devices can in particular be cited: the twin-screw models BC21, BC 45, BC72, BC82 from the company Clextral, the twin screw extruder ZSK 40 from the company Werner & Pfleiderer Gmbh, the models
- the starting galactomannan is guar gum (MEYPRO® - GUAR CSA 200/50 from the company MEYHALL).
- the products obtained after extrusion are dried in an oven at 40 ° C. in order to stabilize them at a humidity of between 8 and 12% by weight.
