  • Fish meal is a commercial product made from fish that is used primarily as a protein supplement in compound feed, especially for feeding farmed fish, Crustacea, pigs and poultry, and companion animals such as cats and dogs.
  • a portion of the fish meal is made from the bones and offal left over from processing fish used for human consumption, while the larger percentage is manufactured from wild-caught, small marine fish. It is powder or cake obtained by drying the fish or fish trimmings, often after cooking, and then grinding it. If the fish used is a fatty fish it is first pressed to extract most of the fish oil.
  • fish meal The uses and need of fish meal are increasing due to the rising demand for fish, because fish has the best feed conversion rate of all farmed animals, can be produced well in developing countries and has a small size, i.e. can be slaughtered for preparing a meal, so that there is no need to store the fish. Furthermore, there are no religious constraints concerning the consumption of fish, fish is a source of high quality protein and it is easy to digest.
  • Fish meal is made by cooking, pressing, drying, and grinding of fish or fish waste to which no other matter has been added. It is a solid product from which most of the water is removed and some or all of the oil is removed. About four or five tons of fish are needed to manufacture one ton of dry fish meal.
  • a commercial cooker is a long, steam -jacketed cylinder through which the fish are moved by a screw conveyor. This is a critical stage in preparing the fishmeal, as incomplete cooking means the liquid from the fish cannot be pressed out satisfactorily and overcooking makes the material too soft for pressing. No drying occurs in the cooking stage.
  • Pressing A perforated tube with increasing pressure is used for this process. This stage involves removing some of the oil and water from the material and the solid is known as press cake. The water content in pressing is reduced from 70% to about 50% and oil is reduced to 4%.
  • the two main types of dryers are: Direct: Very hot air at a temperature of about 500°C is passed over the material as it is tumbled rapidly in a cylindrical drum. This is the quicker method, but heat damage is much more likely if the process is not carefully controlled.
  • Indirect A cylinder containing steam-heated discs is used, which also tumbles the meal.
  • the fish meal has to be transported long distances by ship or other vehicles to the various locations, where it is used.
  • Unmodified fish meal can spontaneously combust from heat generated by oxidation of the polyunsaturated fatty acids in the fish meal. Therefore, it has to be stabilized by antioxidants. Especially advantageous for this purpose are the compounds of formula (I) of the present invention.

  • Oxidative stability was assessed using an Oxipres (Mikrolab Aarhus A/S, Hojbjerg, Denmark).
  • the ML OXIPRES® is designed to monitor the oxidation of heterogeneous products. Consumption of oxygen results in a pressure drop which is measured by means of pressure transducers. The samples are heated to accelerate the process and shorten the analysis time (Mikrolab Aarhus 2012).
  • Sample weights were 50 g. They were loaded into the Oxipres vessels and placed inside the stainless-steel pressure vessel and sealed. The pressure vessels were purged with pure oxygen and filled to an initial oxygen pressure of 5 bar and maintained at 70° C during measurement (D. Ying, L. Edin, L. Cheng, L. Sanguansri, M. A. Augustin, LWT - Food Science and Technology 2015, 62, 1 105-1 11 1 :“Enhanced oxidative stability of extruded product containing polyunsaturated oils.”).
  • the oxygen pressure was recorded as function of time. After sample load and temperature rise the pressure in the device is increasing within 10 hours up to the starting pressure. Thereafter it is decreasing. Consequently, the starting pressure is considered as being the pressure after 10 hours.
  • the analysis ends after 130 hours at 70°C.
  • the oxygen consumption‘0 2 ’ of the tested sample is calculated as follows: Pressure after 130 hours in Oxipres
  • EV Efficacy Value

Batches of 200 g feed were produced in order to handle a minimum of 30 mg of antioxidant. First, a 1% pre-dilution of the antioxidant with the feed material was made. Then this pre-dilution was added to the final batch, mixed, sieved (1 .25 mm sieve) and mixed using a turbula® mixer. Thereafter 55 g of the final batch were packed into polyethylene bags, and stored at 4°C until start of the Oxipres assay. Spare sample were stored at 4°C.
  • An efficacy value > 0.7 is considered as acceptable, an efficacy value equal or greater to the one of alpha-tocopherol as good, and an efficacy value equal or greater to the one of BHT as very good.
  • the results in pet food are shown in the following table 3.

All samples were run in duplicate. The results are shown in Tables 6 and 7.
  • the tocotrienol mixture showed an oxidative stability at all concentration levels used, whereby the effect in fish oil is only slightly lower than that of MNT. In algal oil the effect of the tocotrienol mixture was even slightly better than that of MNT at the low level.
  • the Protection Factors (PF) for the tocotrienol mixture in oil were calculated in percentage as:
  • a storage stability study for fish oil (XBUFG30TG) containing 2 different levels of the tocotrienol mixture (0.5 and 2 mg/g) was performed to compare the variation of primary and secondary oxidation products generated during storage at ambient temperature as a result of oxidation of the oil in the presence of these compounds.
  • tocotrienol mixture 0.5 mg/g and 2 mg/g were added, each individually, to 60 g of fish oil samples in glass amber bottles, thoroughly mixed under nitrogen and stored at ambient temperature storage for 2 weeks. All sample bottles were left open to air, away from light.
  • the tocotrienol mixture was readily soluble in fish oil.
  • the primary oxidation products, hydroperoxides, were determined in terms of peroxide value (PV), and the secondary oxidation products were measured and determined as anisidine reactive substances or p-anisidine value (p-AV).
  • Conjugated dienoic acid (CD) levels which are also indicative of the primary oxidation were also determined.
  • Peroxide values (PV), p- anisidine values (p-AV) and conjugated dienes as percentage dienoic acid were determined at different times for up to 2 weeks.
