MASTER PIGMENTERS

NATURAL PIGMENTS

PIGMENTATION ORIGINATED HISTORICALLY

• The visual appearance is an important
  characteristic for the consumer.
• Pigmentation is associated with
• healthy animals and quality products.

3
Country preference concerning pigmentation

• corn producing countries
• corn contains natural pigments, xanthophylls
• free range layers grass contains natural
  pigments, xanthophylls

CONTROL OF PIGMENTATION

• Mainly visual observations
• They are subjective
• individual observations
• source of light
• background colour
• Colour meter
• Chromatometer
• 3 Dimensional determination

Pigmentation variables

• 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.

8
FACTORS AFFECTING PIGMENTATION

• 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.

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).

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)
11
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
12
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 trendconsumers are moving to natural.
Researches show doubts about healthiness of
synthetic pigments.

SYNTHETIC PRODUCTS FOR PIGMENTATION

• ROCHE
• Carophyll Yellow (10) apo-ester
• Carophyll Red (10) canthaxanthin
• BASF
• Lucantin Yellow (10) apo-ester
• Lucantin Red (10) canthaxanthin

Comparison of product efficiency synthetic
natural 6 1 1 kg synthetic Yellow 6 kg
NUTRI-GOLD YELLOW In 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

BROILER DIETS WITH XANTHOPHYLLS FOR A GOLDEN
YELLOW SKIN COLOUR
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
Example of dosage recommendation
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
