Aim: To establish the micro and macronutrient values of O. hubbsorum B and to evaluate its potential contribution to Mexican diet, since this organism is available all year in the Mexican Pacific Coast. Study Design: Transversal study.Place and Duration of Study: Samples of Octopus hubbsorum were bought from fishermen in Acapulco, in the Mexican Pacific Coast during Autumn 2016. Methodology: Five O. hubbsorum were bought from local fishermen during the second week of Novermber, 2016. Moisture content was determined using the direct drying method. Protein content was determined according to the principle of the Kjeldahl method. Lipid content determination was carried out by the semicontinuous solvent extraction method. Determination of raw fiber was performed by an acid- alkaline digestion. Calcium and iron content was determined by atomic absorption spectroscopy, whilst phosphorous content analysis was performed by colorimetry. Results: High amount of water and protein were found in O. hubbsorum B, being 64.15 % and 69.38%, respectively. On the other hand, lipids were low and no fiber was found. Finally, the content of Ca, Fe and P in mg/100g was 24.33, 1.4 and 120.67 respectively.Conclusion: Octopus hubbsorum is a rather good source of proteins. This could help diminishing proteic-caloric malnutrition of people living in coastal areas. However, octopus should be eaten with other nutritional sources to get a balanced diet.
FAO (Food and Agriculture Organization of the United Nations) declared that 12% of the world's population is undernourished while in Mexico the number is around 5%. Minerals are essential for the daily diet; iron (Fe) is an important mineral on human welfare because it has a main role on the function of the immune and central nervous systems, among others. Most Mexicans fulfill their iron requirements from vegetables, which are poorly absorbed; nevertheless, in coastal populations, where seafood-rich in iron-is available, it is not consumed on a regular diet. The aim of this work was to analyze minerals, focusing on the iron content of Octopus hubbsorum B (Cephalopoda: Octopodidae), an animal of the Mexican Pacific coast. Three specimens were analyzed, two from the north and one from central Pacific Ocean. Data obtained for the central Pacific Octopus was 0.008% and data for the North Pacific were 0.008% and 0.011%, repectively. In conclusion, the supply of iron for the Mexican diet provided by Octopus hubbsorum B is significant, therefore is recommended to consume more of this resource, to diminish iron deficiency, a world-wide problem, and to improve human health.
