Definitions

  • the present invention relates to a high oil and protein content fish feed composition, uses thereof and methods of preparing pellets therefrom.
  • fish feed must, for nutritional reasons, contain about 35-50% protein. Protein, however, is expensive. This is due, in particular, to an excessive reliance on fish meal, the quality and prices of which are variable, with global supply declining despite increasing demand. The use of fish meal is also undesirable for environmental and water pollution reasons.
  • oils are not, in themselves, expensive, methods suggested to date for incorporating oils into fish feeds have proved both costly and unsatisfactory.
  • the present invention provides such a method.
  • a fish feed composition characterised in that it comprises 15-75%, preferably 20-75% by weight gluten (such as vital wheat gluten or corn gluten) and 25-85%, preferably 40-85% by weight dehulled oilseed (such as dehulled rapeseed).
  • gluten such as vital wheat gluten or corn gluten
  • dehulled oilseed such as dehulled rapeseed
  • composition may comprise:
  • a fish feed pellet characterised in that it comprises at least 75% of the described composition and, in one embodiment, a coating.
  • a process for preparing a fish feed composition comprising blending 15-75%, preferably 20- 75% by weight gluten; 25-85% by weight, preferably 40-85% by weight dehulled oilseed; and optionally, one or more additional ingredients (such as additional protein or lipid sources, carbohydrate sources, and additives).
  • a process for preparing fish feed pellets characterised in that it consists of (a) blending the ingredients of the fish feed composition; and (b) shaping the blend obtained in step (a) into pellets.
  • said process may further comprise a step (Ci) of treating the pellets obtained in step (b) with steam for 1 to 30 seconds and/or a step (c ) of coating the pellets obtained in step (b) or (ci).
  • the present invention relates to a fish feed composition
  • a fish feed composition comprising 15-75% by weight gluten and 25-85% by weight dehulled oilseed.
  • Gluten is the protein found in many grains and cereals such as wheat, corn, oats, rye and barley.
  • the term "gluten” as used herein refers to gluten from any available source and to mixtures of gluten from different sources.
  • the gluten may be in its native form, or it may be modified (e.g. hydrolysed).
  • the gluten will comprise 50% - 100% by weight vital wheat gluten and/or corn gluten.
  • Gluten is comprised in the composition of the present invention in quantities of 15- 75%, preferably 20-75% by weight, even more preferably 20-50% by weight.
  • the overall composition should ideally comprise 30-75% by weight protein (for some young fish, for example, it is desirable to have a protein content of approximately 70%).
  • the overall composition will comprise 35-60%, even more preferably 40-50%, by weight protein.
  • protein sources other than gluten can also be added. These can include any one or more vegetable or animal sources (such as soy concentrate, fishmeal or hydrolysed fishmeal), or mixtures thereof.
  • the composition also comprises 25-85% by weight dehulled oilseed.
  • it comprises 40-85%, even more preferably 55-85% by weight dehulled oilseed.
  • Oilseed plants include rape, saffiower, sunflower, soya, flax, cotton, mustard and crambe (or other plants of the Brassica genus) for example. Any one or more of these can be used as the source of dehulled oilseed. Preferably, however, rape, sunflower and/or flax will be used. More preferably, rape will be used. By removing the hull (which contains mostly indigestible carbohydrates), the amount of oil available from the seeds is substantially increased. Any method available in the art can be used to dehull the seeds. Preferably, however, the hulls will be gently cracked and removed without milling the seeds. According to one embodiment, the dehulling step will be followed by a heat-treatment step (e.g. heat shock). It has indeed been found that heat- treatment of dehulled rapeseed, for example, deactivates myrosinase and avoids toxic isothiocyanate formation during feed processing and storage.
  • a heat-treatment step e.g.
  • an additional source of lipids can be selected from any one or more vegetable or animal sources (such as soy oil, corn oil, palm oil, castor bean oil, maize germ oil, fishmeal or fish oil), or mixtures thereof.
  • the overall content of lipids (i.e. lipids from dehulled oilseeds + optional additional sources of lipids) in the fish feed composition should preferably be 25-55% by weight, even more preferably 35-50 % by weight.
  • the composition of the invention may also contain one or more carbohydrates. Preferably, it will comprise 0-15% by weight carbohydrate material.
  • the carbohydrates can be used as binding or bulking agents or as a source of energy.
  • the carbohydrate will be selected from a cold water soluble starch, a starch derivative (e.g. starch ethers, starch esters, dextrins, etc.) and mixtures thereof.
  • a cold water soluble starch is a starch which develops viscosity when dispersed in water at a temperature below 60°C, without the need for further heating.
  • additional feed ingredients may include vitamins and/or minerals, amino acids, pigments, antioxidants, colouring agents, enzymes, carotenoids, preservatives, pro- and/or pre-biotics, trace elements and any other compounds commonly used in small quantities in feed compositions.
  • the composition will contain up to 5% by weight of such additives.
  • composition can be prepared simply by blending gluten and dehulled oilseed in the quantities specified above, if necessary with water and/or other aqueous solutions. Where it is desired to include one or more carbohydrates and/or additives, these can be incorporated by blending with the other components of the composition. Blending can be carried out in any suitable mixer. These will be apparent to the person skilled in the art, but include, by way of example, ribbon mixers, plough shares, nauta mixers and continuous mixing screws.
  • the composition can be used in the preparation of high oil content shaped, hardened, dried, flaked and/or coated fish feed.
  • Said pellets will advantageously comprise at least 75%, preferably up to 100% by weight of the composition of the invention. Ideally, the pellets will comprise 95-100% by weight of said composition.
  • the coating will preferably include one or more cold water soluble starches or starch derivatives such as pre-gelatinised starch and/or maltodextrin. It may also (or alternatively) include one or more of wheat gluten, hydrolysed wheat protein and gelatine. Other materials suitable for use in coating fish feed pellets will be known to the skilled person.
  • the pellets of the present invention can be prepared simply by (a) blending the ingredients of the fish feed composition (as described above) and (b) shaping the obtained blend into pellets.
  • the blend of step (a) can be milled (in a step (a')) before being shaped in step (b).
  • Shaping can be achieved using any available means.
  • the pellets will be shaped using a die press, even more preferably they will be shaped using a conical die press.
  • the dies may be of any suitable dimensions (e.g. 4x50mm; 4x80mm; 6x50mm) but will preferably have a diameter:thickness ratio of about 1:20.
  • Preparation of the pellets as described above does not require heating or other potentially costly treatments.
  • the use of an extruder for the preparation of pellets can be avoided. Accordingly, energy input can be reduced and, advantageously, the process can be applied at farm level (without the requirement for special machinery or skills).
  • pellet shape The choice of the pellet shape, volume and weight will of course depend on the desired application. For example, different fish types will require different pellets.
  • the pellets of the present invention can be adapted for any type of farmed fish including yellowtail, sea bream, halibut, yellow jack, carp, trout, eel, cat fish and, most preferably, salmon.
  • the specific (nutritional and physical) requirements for each of these fish types will be known to the skilled person.
  • the process of preparing the pellets of the present invention may comprise a further step (ci) of treating the pellets obtained in step (b) with steam for 1 to 30 seconds.
  • This s_imple procedure allows the surface of the pellet to be hardened thereby further improving the. pellets' oil retention and water stability properties.
  • the thickness of the hardened layer will increase with the length of steam treatment and will affect the sinking behaviour of the resultant pellets.
  • this steam treatment can be used to ensure that the pellets have the correct floatability for the type of fish being fed. It will also improve the pellets resistance against physical stress, for instance during storage, transport and distribution.
  • the steam treatment step will preferably heat the pellets to a temperature of 70-100°C, even more preferably to a temperature of 85-95°C.
  • a coating step (c 2 ) can also be included, as mentioned above. Examples of materials that can be used for coating have been listed.
  • the coating step can be used in addition to or instead of the steam treatment and it can include the application of several coats (depending, for instance, on the final thickness required), the application stages being separated by drying stages.
  • Mixtures 1-4 were blended and formed into pellets according to the following methods:
  • the components of the above compositions were put in a 11 cup and mixed in a blender (Waring Blender 8010, speed 22000 rpm with no-load), without additional heating, during 60 seconds. After mixing, a paste is formed in which all the oil of the composition is absorbed. This paste has sufficient firmness for it to be formed into a fixed shape. If necessary, firmness can be increased by the addition of 3-5% by weight water into the mixture during blending.
  • the blended fish feed was shaped by putting it through a meat mincer and cutting it at the exit. This resulted in a fish feed with a cylindrical shape, a diameter of up to 5mm and a length of approximately 10mm. Finally, the pellets were treated, for a few seconds, with steam to create a hard surface layer.
  • a paste was prepared and shaped using a meat mincer as in Method 1.
  • the shaped fish feed was then placed in a 250 ⁇ m sieve and a 10% suspension of pre-gelled starch
  • a paste was prepared and shaped as in Method 1. Further treatment followed the same procedure as in Method 2 but with the following types of suspension and powdering:
  • mixtures 1, 2, 3 or 4 were placed in a dosing screw that forms the dry feeding supply of a Clextral BC45 extruder. Any fluid ingredients were blended and dosed to a pump that forms the wet feeding supply of the extruder.
  • the extruder was operated as a mixing device. No additional heating was used. The mixture left the extruder as a dough into which all the oil has been absorbed. This paste had sufficient firmness for it to be formed into a fixed shape. If necessary, firmness can be increased by the addition of 3-5% by weight water at the fluid inlet of the extruder.
  • Pellets were formed by cutting the paste at the extruder outlet using the rotating knife.
  • the extruder used to form the pellets had a circle-shaped exit resulting in cylindrical shaped pellets.
  • pellets fell onto a perforated conveyer on which they were treated with steam for a few seconds, resulting in a hard surface layer.
  • a paste was prepared and shaped as in Method 4.
  • the formed fish feed fell on a perforated conveyer that ran through a bath containing a suspension as described in Methods 2 or 3.
  • the fish feed was powdered and gently dried after excess suspension had been flowed off through the conveyer.
  • the powder was the same as described in Methods 2 and 3. This treatment resulted in a hard surface layer.
  • pellets were formed with hard surface layers (either through steam treatment of by coating).
  • the hard surface layer prevented oil from leaking and gave the pellets strength.
  • the pellets were stable, did not loose oil and had a sinking profile adapted to e.g. farmed salmon production. Hardness was sufficient for resistance against physical stress during storage, transport and distribution.
  • a fish feed based on the combination of wheat gluten, dehulled rapeseed and fish protein was prepared as follows:
  • the above blend was pre-conditionned in a turbulator mixer with steam injection until a temperature of 75°C was reached.
  • Pellets were then formed using a Heessen V3-30 press with hydraulic roll adjustment and a die of 5x75mm at a speed of +/- 300kg h. The pellets left the press at 80°C. Thus formed, the pellets were cooled on a cooling belt under atmospheric conditions during 35-40 minutes before being packaged. The pellets were found to be of good overall quality.
