  • 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%. Drying: If the fish meal is under-dried, moulds or bacteria may grow. If it is over-dried, scorching may occur and this reduces the nutritional value of the meal.

  • Indirect A cylinder containing steam-heated discs is used, which also tumbles the meal.

  • 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:
  • EV Efficacy Value
  • Carnosic acid was mixed into matrix 1 and 3 (pet food, fish meal) in an equimolar ratio compared to BHT. 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.
  • Example 2 Antioxidant activities of carnosic acid in fish oil and algal oil
  • Carnosic acid was tested in fish oil and algal oil.
  • the blank oil i.e. oil without any antioxidant, and oil containing“MNT” have been used as benchmark. Any compound better in antioxidant activity than the blank oil indicates that it has antioxidant activity.
  • the comparison with MNT gives an indication about the amount of the antioxidant effect, relative to the activity of MNT.
  • MNT are mixed natural tocopherols commercially available as e.g., “Tocomix 70 IP” from AOM (wholesome Aires, Argentina).
  • Tocomix 70 IP comprises d-alpha-tocopherol, d-beta-tocopherol, d-gamma-tocopherol and d-delta-tocopherol, whereby the total amount of tocopherols is at least 70.0 weight-% and the amount of non-alpha tocopherols is at least 56.0 weight-%.
  • Carnosic acid and MNT were evaluated primarily for their oxidative stability by the Oil Stability Index (OSI) measurements. Two different levels of these antioxidants (0.5 and 2 mg/g) were used in 5 g of natural fish oil (Product code: FG30TG) and used in the Oxidative Stability Instrument at 80°C with the air flow rate of 40 psi.
  • OSI Oil Stability Index
  • VY00010309 were also determined. Crude algal oil contained about 1 .6 mg/g of mixed natural tocopherols (MNT) prior to use in these experiments whereas fish oil did not contain any antioxidants.
  • MNT mixed natural tocopherols
  • Carnosic acid was used at different times in the Oxidative Stability
  • Oil Stability Index for carnosic acid at 500 and 2000 ppm levels in fish oil and algal oil, respectively, in comparison with the same amounts of MNT, is shown in Tables 6 and 7.
  • Carnosic acid provides a remarkable protection factor in fish oil which can be further improved by combining with AP. It also indicates that carnosic acid may be used in much smaller amounts than used in these experiments to improve the oxidative stability of PUFA-containing oils such as marine oil and algal oil.
  • Table 1 1 shows the possible improvements of the Oil Stability Index of MNT using 2 common synergistic compounds, ascorbyl palmitate and carnosic acid.
  • carnosic acid was only used at a level of 2 mg/g. Compared to the same level of MNT, carnosic acid showed higher PVs than those of MNT (Table 12). There was no considerable variation in p-AV and CD (Tables 13-14) during the storage.
  • Tables 12, 13 and 14 show the PV (eeroxide value), p-AV (2-anisidine value) and CD (conjugated dienoic acid in %) of the fish oil samples stabilized with carnosic acid.
