Analyse de composition des Aliments pour Animaux

L’alimentation animale en Tunisie a connu ces dernières années un développement remarquable il n’y a qu’à voir le nombre de plus en plus croissant d’entreprises présentes sur le marché.Des aliments complémentaires minéraux, aux prémélanges d’additifs, prémix et spécialités nutritionnelles adaptés aux besoins spécifiques de chaque client, la diversité des produits soulève le problème de la qualité. Le LCAE, accompagne ces industriels dans l’amélioration de leurs produits par le contrôle de leur composition

Fat Bodies

Vegetable oil is a fatty, creamy and thick material, often liquid at room temperature and which is insoluble in water, oils consist of lipids formed from triglycerides composed of fatty acid molecules esterified by glycerol (a molecule of 'alcohol). They are major components of the energy of the human body, because fat provides calories in large numbers.

Dairy products

dairy products (milk, cheese, yogurt, cream, butter, etc.) are among the foods recommended by health professionals because they are rich in calcium. However, you should avoid consuming poor quality milk which promotes the development of cardiovascular diseases (CVD). This is why it becomes important to analyze milk in all its forms before marketing it. The aim is to protect the consumer.

 Products of Plant Origin - animal feed

The laboratory offers analyzes to counter fraud and research the composition of food products.

Food fraud can be the intentional substitution, dilution or addition of a food or industrial product with the intention of financial gain, by increasing its value or reducing its production cost, or by fraudulent advertising. by incorrect labeling. The most affected foods are: Spices, sugars, pasta,….

With respect to its labeling, the laboratory ensures the compliance of the food or animal feed product, as well as the compliance of its composition with the standards of specifications or regulations in force.
