ABSTRACT
Chemical composition of eggs of the Olive Ridley Lepidochelys olivacea (Testudines Cheloniidae) and its potential as a food source. The Olive Ridley is a worldwide distributed species with high nesting production per season, and in La Escobilla Oaxaca, México, there is a 70% of non-hatched eggs that are lost. In order to evaluate their potential use as a source for human and animal food products, their chemical composition was analyzed. Lyophilized egg samples from 25 turtles were obtained and were analyzed following the analytical methods for fatty acids, protein, fat, ash, moisture, amino acids, vitamins, cholesterol and microbiological agents. The analytical composition obtained was (g/100g) moisture (4.7), ash (3.8), protein (53.7), and fat (47.4). The essential amino acid (g aa/100g protein) content was Ile (4.4), Lys (6.6), Leu (7.4), Met+Cys (8.8), Phe+Tyr (10.8). The vitamin content was retinol (340μg/100g), cholecalciferol (5.9μg/100g) and 8.6mg/100 tocopherol, 0.3mg/100g thiamine and 1.1mg/100g riboflavin. The total lipid content (TL), fatty acids (FA), and cholesterol (Chol) were divided into three groups based on the weight of the turtle (TL) (44.3-48.7-49.1g/100g) and (Chol) (518.4-522.5mg/100g-728.7). A total of 17 Saturated FA (SFA), 8 Monounsaturated FA (MUFA) and 11 Polyunsaturated FA (PUFA) were identified. The most abundant SFA (mg/100g) were C140 (445-772), C160 (485-1263); MUFA C161 (456-716), C181n-9c (904-1754), and PUFA C204n-6 (105-217); two n-3 fatty acids were identified EPA (48-103) and DHA (97-189). There were significant differences (Fisher, p<0.05) for (Chol), total FA, SFA, MUFA, PUFAs and n-3 (EPA + DHA) FA. It was not detected any microbiological agent. In conclusion, lyophilized L. olivacea eggs are an option for its inclusion in the development of food products as they can be used as a high quality biological protein and n-3 fatty acid source for fortification and enrichment.

RESUMEN
Por su potencial como fuente alimenticia, se analizó la composición química de huevo de Lepidochelys olivácea en La Escobilla, Oaxaca, México. El Instituto de Ciencias del Mar y Limnología de la Universidad Nacional Autónoma de México proporcionó 250 muestras de huevo liofilizado de 25 tortugas, que se analizaron siguiendo métodos oficiales para humedad, cenizas, proteína, grasa, lípidos totales(LT) y análisis microbiológicos; además de ácidos grasos(AG) por cromatografía de gases, aminoácidos(AA), vitaminas y colesterol(col) por HPLC. Los resultados fueron los siguientes (g/100g) humedad(4.7), cenizas(3.8), proteína(53.7) y grasa(47.4). AA esenciales (g aa/100g Proteína) Ile (4.4), Lys(6.6), Leu(7.4), Met+Cys (8.8), Phe+Tyr (10.8); retinol (340μg/100g), colecalciferol (5.9 μg/100g), tocoferol (8.6), tiamina (0.3) y riboflavina (1.1) (mg/100g). Y los de (LT), (AG) y (Col) se concentraron en tres grupos por peso de tortuga (LT) (44.3-48.7-49.1g/100g), (Col) (518.4-522.5-728.7 mg/100g). Entonces se identificaron 17 AGSaturados, 8 AGMonoinsaturados y 11 AGPoliinsaturados. Los AGS más abundantes (mg/100g) C160 (485-1263), AGM C161 (456-716), C181n-9c (904- 1754) y AGP C204n-6 (105-217), EPA (48-103) y HA (97-189). También, existió diferencia significativa (Fisher, p<0.05) para (Col), AG totales, AGS, AGM, AGP y AG n-3 (EPA+DHA). No se detectó presencia de agentes microbiológicos. El huevo liofilizado de L. olivacea es una opción para el desarrollo de productos alimenticios por su proteína de alto valor biológico y ácidos grasos n-3.
