FISHMEAL STABILITY TRIALS

Evaluating all options to provide alternatives should ethoxyquin not

be re-authorised

IFFO TRIAL

•Duration 18 months

•300 ppm ethoxyquin dosage effective (50 ppm residual)

Tocopherols proven safe but higher loss of omega-3’s (250 ppm residual)

•Report available

OTHER CONCLUDED TRIALS

•Blend: (1,000 ppm + 2,000 ppm)

•Tocopherol with Rosemary extract

•Both concentrations passed self-heating test at 8 months

•Tocopherol residual 103 ppm (1,000 ppm treatment) after 8 months

Peru: anchovy

FUTURE PLANNED TRIALS

Vitamin E

CVEP APPROACH

• Production of anchovy fishmeal samples in South Africa

• Start in January 2018 at the latest for one year

• Laboratory analyses performed by experienced local lab

DETERMINATION OF SAFE VIT E DOSAGE

• Establish range of safe & effective Vit E dosage levels supported

by mathematical-chemical calculations

• Implementing calculated dosage range in the trial to determine

the most probable quantity effective in fish meal stabilisation

CVEP, A Cefic Sector Group, represents the producers of vitamin E

Peruvian industry collaboration - SNP

Decreased dosage levels of ethoxyquin, BHT

and tocopherols

Blends:a) Tocopherol & rosemary extractb) BHT & BHAc) Gallic acid (from “tara pods”) & ascorbylpalmitate (possibly)

Start 2017/2018

AMENDMENT TIMELINE FOR THE IMDG CODE

SP 308 Stabilization of fish meal shall be achieved to preventspontaneous combustion by effective application ofethoxyquin, BHT (butylated hydroxytoluene) or tocopherols(also used in a blend with rosemary extract) at the time ofproduction.The said application shall occur within

twelve months prior to shipment.Fish scrap or fish meal shall contain at

least 50 ppm (mg/kg) of ethoxyquin, 100ppm (mg/kg) of BHT or 250 ppm(mg/kg) of tocopherol

based antioxidant at thetime of consignment.
