Abstract
Antioxidant could be extracted and isolated from squid inks. Squid ink in the form of melanin free ink (MFI) could be act as an electron donor which can stabilise free radicals in lipid oxidation. Studies were carried out to assess the antioxidant activity of squid inks converted into MFI in different dilution and to optimise the extraction conditions for the application of MFI as an anti-oxidative agent on fish product. Three different concentrations of MFI extracts i.e., 0%, 0.75% and 1.5% were applied on soft-boned milkfish at 10°C, 20°C and 30°C temperature storages for nine days, with observation every three days. The results showed the animism of the ink through chemical parameters, antibacterial effect, and sensory analysis. MFI at a concentration of 0.75% was revealed to be effective in prolonging cold storage shelf life of soft boned milkfish, which was confirmed through comprehensive sensory analysis evaluation and measurement of chemical changes including water, protein, lipid and ash content. It was also discovered that 0.75% MFI significantly prolonged the cold storage period of soft boned milkfish until six days, indicating that it may be developed to be a natural preservative for marine products.
期刊介绍:
Technology is an increasingly crucial input in the industrialisation and development of nations and communities, particularly in the current era of globalisation, trade liberalisation and emphasis on competitiveness. The shared technologies and innovations of today are giving birth to the radically different agrifood industries and communities of tomorrow. There is mounting evidence that investments in postharvest research and infrastructure yield high rates of return that are comparable and often higher than investments in on-farm production alone.
