Determination of some quality properties of "hamsi kaygana" prepared with different additives

Abstract

This study was aimed to determine the changes of the local anchovy meal which is known as hamsi kaygana in Turkey during cold storage at +4 degrees C +/- 1 degrees C. Physicochemical (pH, TVB-N, TMA-N, and TBA) shelf life analyses were carried out for hamsi kaygana samples. It was confirmed that the pH values obtained from research groups were within the limit values of the literature. No statistically significant difference was observed (p>.05) between control, stinging nettle, and rosemary groups that were within all created product groups on 12th day of storage, and the observed difference was only present in cumin group (p<.05). Upon examining TVB-N (Total Volatile Basic Nitrogen) values on 12th day of storage, we saw the lowest TVB-N value (17.01 +/- 0.21mg/100g) was at stinging nettle group. However; it was found out that highest TVB-N value belonged to cumin group with the value of 19.38 +/- 0.42mg/100g. It was found that 12th day TBA (Thiobarbituric Acid) values of all other groups except control group did not exceed limit values. Among TMA-N (Trimethylamine Nitrogen) values of all groups on 12th storage period, the lowest value belonged to cumin group samples. While the highest TMA-N value was found as 14.70 +/- 0.30 in control group samples. Therefore, the results showed us that using dried herb and spices in hamsi kaygana production and the storage of the products have an influence on shelf life.
