Abstract—Fish protein concentrate (FPC) is a healthy, sustainable and high nutritive product that sanitizedly produced from fishes in which, protein and other nutrients are more concentrated than in fresh fishes. The aim of this research is to study on the sustainability of FPC produced from kilka in two VP (Vacuum Packaging) and MAP (Modified Atmosphere Packaging) packages in light and darkness condition during six months. According to our results protein rate was 91.2%, lipid:0.5%, ash: 3.6%, moisture: 2.3%, TVN: 10 ml/100gr and peroxide: 5meq/kg. Amino acids includes; Alanin: 38.80,Argenine: 62.60, Aspartic: 73.20, Cysteine: 9.20, Glutamic:122.40, Glysine: 34.00, Histidine: 29.40, Isolucien: 45.20, Lucien: 75.3, Lysine: 80.60, Metionine: 32.30, Phenylalanine:69.80, Proline: 35.50, Serin: 31.70, Threonine: 43.40, Tyrosine:30.60, Valine: 52.50 (mg/g) and fatty acids includes; Arachidicacid: 1.25, Oleic acid: 40.50, Stearic acid: 5.52, Palmitoleic acid:27.95, Myristoleic acid: 0.28, Myristic acid: 2.94 (g/100g) were also determined. Amino acids and fatty acids were also determined. Lipid rate in FPC after 6 months in light conditions in VP package has changed from 0.50 to 0.43 %, in MAP package combined of 60% C02, 30 % N2 and 10% O2, was changed from 0.50 to 0.41 % which showed small decrease. Indarkness condition in VP and MAP packages has changed from0.50 to 0.49 and 0.47 % respectively that is not significant(P>0.05). It was also detected that light condition lead to more decrease in lipid content but that was not significant (P>0.05).Protein rate of FPC has changed from 91.2% to 85.40% during six months at light condition in VP Package and from 91.2% to77.40% in MAP package that is significant (P<0.05). But at darkness condition protein rates were changed from 91.2% to89.10% and 85.30% respectively in VP and MAP packages, these changes are significant (P<0.05) but more decrease in MAP package was detected again. Therefore, maintenance offish protein concentrate is recommended under darkness condition.
