Nutritional Analysis of Octopus hubbsorum B (Cephalopoda: Octopodidae) from the Pacific Ocean, Acapulco, Guerrero, México

Introduction: Mexico is a country with nutrition-related problems, mainly regarding protein-energy
deficit and low consumption of minerals and vitamins. This has contributed to Mexico ranking second
on adult obesity within countries of the OECD (30% of the population). On the Mexican littoral, many
cephalopods exist but only few octopods are used for human consumption. According to Mexican
authorities, only four species of octopods are fished, although there are 15 of these benthonic zone
organisms that can be used for many purposes.
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/100 g was 24.33, 1.4 and 120.67 respectively.
Conclusion: Octopus hubbsorum B 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.
