ABSTRACT
The aim of the present study is to present a new anchovy protein concentrate and compare it to other similar fishery products. A 76.4% protein concentrate was prepared from fresh Peruvian anchoveta (Engraulis ringens) (APC) by means of acid treatment with 1% citric acid, solubilization with 1% sodium chloride, and isoelectric precipitation processes. Remaining fat was 5.2%, and 0.51 Aw indicates good stability. When APC was rehydrated for 10 minutes, it had a 3.5 initial weight increase. It provided 17.8% protein of very high nutritional quality, with only histidine content deficient for children 1–2 years old. Fat content in APC offered 33.4% EPA+DHA. No changes in the essential/non-essential amino acids (EAA/non-EAA), polyunsaturated/saturated fatty acids (PUFA/SFA), or w6/w3 ratios were observed as a result of the process in the raw material. Because of the high sodium content, a 25 g portion is recommended to fulfill nutritional FAO recommendations. APC can be considered as an important source of calcium (30% adults and 35% children requirements), phosphorous (30% adults and 52% children requirements), and iron content (approximately 20% adults and children needs). APC is an important high-quality protein, providing w-3 fatty acids, calcium, phosphorous, and iron.
