NATURAL PIGMENTS
PRES/Pigments/1 DD 14/11/02
PIGMENTATION ORIGINATED HISTORICALLY
The visual appearance is an important characteristic for the consumer.
Pigmentation is associated with healthy animals and quality products.
PRES/Pigments/1 DD 14/11/02
Layers and broilers are unable to synthesise their own pigments.
Pigments added to the diet to obtain the desired colour
Country preference concerning pigmentation
corn producing countries corn contains natural pigments, xanthophylls free range layers grass contains natural pigments,
xanthophylls

PIGMENTATION
1. Analyse the market needs in terms of colours an economic factor
2. The colour of egg yolks from light-yellow to golden-yellow expressed in the Roche Colour Fan score number
3. The colour of the skin and shank of broilers.

CONTROL OF PIGMENTATION
•Mainly visual observations•They are subjective:
• individual observations
• source of light
• background colour

•Xanthophyll level varies in raw materials genetic, field and climate effects harvest and storage conditions
temperature
light
time
•The results on the pigmentation depend on :
•the xanthophyll content and the deposition rate by the
animal.
•The adaptation period for layers is about 5 days.
Pigmentation variables
PRES/Pigments/1 DD 14/11/02
Oxidation Vitamin E support the absorption (biological antioxidants) Antioxidants in feed to protect the fat and the xanthophylls
from oxidation.
The feed intake
Stress conditions (temperature, etc.)
Diseases
Salmonellosis and coccidiosis damage the mucosa of the
digestive tract and reduce the absorption of carotenoids.
Processing techniques
High temperatures may degrade xanthophylls.
FACTORS AFFECTING PIGMENTATION
PRES/Pigments/1 DD 14/11/02
WHAT ARE NATURAL PIGMENTS
Natural Pigments are based on natural Carotenoids mainly used in poultry feed. (fish feed is a new opportinuty).
They are obtained from dehydrated, stabilized, homogenized and soaponified Marigold extract (yellow pigments) and Paprica extract (red pigments).
PRES/Pigments/1 DD 14/11/02
PRODUCTION
1. Flower Meal production
2. Pelletting : To have a better action of the solvent
3. Oleoresin production and extraction of the solvent (ether)
4. Oleoresin saponification (with Potassium)
5. Adsorption on a dry carrier (for powder products)
PRES/Pigments/1 DD 14/11/02
Saponification:
Hydroxycarotenoids have to be saponified before being absorbed. Saponification improves the digestibility of the original esterified Tagete and Capsicum xantophylls.
Isomerisation:
The most bioavailable pigments are on trans form. To reach a higher percent of trans form, flowers are selected genetically. A chemical processing technique called isomerisation (cis to trans) can also be used
PRES/Pigments/1 DD 14/11/02
NATURAL and SYNTHETIC
Natural for:
Yellow skin broilers: natural is preferred because gives a uniform gold pigmentation
Vegetal eggs: synthetic pigments are not allowed
Pasta eggs: better colour, more uniform and resistant to heat
General trend:consumers are moving to natural. Researches show doubts about healthiness of synthetic pigments.

BASF Lucantin Yellow (10%) apo-ester Lucantin Red (10%) canthaxanthin
Comparison of product efficiency : synthetic : natural = 6 : 11 kg synthetic Yellow = 6 kg NUTRI-GOLD YELLOWIn broiler diets 8 kg NUTRI-GOLD YELLOW can replace 1 kg synthetic product.
In some countries synthetic products are prohibited by law because of safety reasons

Several diets are normally used; A starter, grower and finisher diet. It is efficient to have lower xanthophyll levels in the starter - and higher levels in the finisher diet
BROILER DIETS WITH XANTHOPHYLLS FOR A GOLDEN YELLOW SKIN COLOUR
Example of dosage recommendation :
Starter diet - No NUTR-GOLD YELLOW dryGrower diet - 0.5-1.0 kg/t NUTR-GOLD YELLOW dryFinisher diet - 1.0-1.5 kg/t NUTR-GOLD YELLOW dry
The dosage depends on the natural (ca. 15 ppm) xanthophyll level, body weight, feed conversion.For more intensive pigmentation small amounts of red pigments can be added. ( 0.5-1.0 kg/tonne NUTRI-GOLD RED)
