Specifications:

Fishmeal is an excellent source of protein for poultry. It has high levels of essential amino acids such as methionine and lysine, and it also has a good balance of unsaturated fatty acids, certain minerals (available phosphorus), and vitamins (A, D, and B-complex). The use of fishmeal is usually restricted to 5% to 10% of the content of poultry diets.

Oxidation and antioxidants

Fish meals with high oil contents can present problems during storage. Fish oil in the meal will oxidise after production and the reaction can lead to considerable rises in temperature. This can become a fire hazard. One method of overcoming this problem is to allow the oil to oxidise before packing by holding the meal in bulk stacks or spread out on the floor. Sacks of meal can also be stacked singly for a few weeks while oxidation occurs. These procedures allow dissipation of the heat generated by oxidation rather than allowing it to build up in confined spaces. Another way of overcoming this problem is to pack the meal in airtight, polyethylene laminated multilayer sacks which will hamper the diffusion of oxygen into the meal.

The use of antioxidants to stabilise fish meals is common these days. The amount of antioxidant required depends on the degree of unsaturation of the oil and varies with fish species. The two most common antioxidants used for fish meal are ethoxyquin and butylated hydroxytoluene (BHT). It is common practice to add between 400 and 700 ppm ethoxyquin to fish meal immediately after drying and prior to packaging. The antioxidant will prevent the uptake of oxygen by the meal and so prevent spontaneous heating.

Production Flow:

1. Heating or cooking to coagulate protein and release water and oil.
2. Pressing to separate liquids from solids.
3. Drying.
4. Grinding to produce a powdered or granular end product.

Bags and storage

Fishmeal bags normally contain 50 kg. In tropical areas, the bag material is often hessian made from woven jute. This relatively open structured material allows the passage of water vapour and oxygen. Under humid conditions, the meal which is hygroscopic may absorb moisture and, if the moisture content rises above 15 per cent, moulds and bacteria may become active and the meal will compact into a solid lump in the bottom of the bag.

In many modern fishmeal operations, paper and polyethylene laminated sacks are used. These sacks have advantages over the more traditional hessian ones in that:

1. They prevent the rapid movement of oxygen and water.

2. To some extent the meal is protected from rodents and insect attack and from contamination by moulds and bacteria.

3. The meal cannot seep from the sack as it can through hessian.
