Abstract

Aims: The objective was to experimentally determine the quality specification limits for the pool of shark-liver oil from Cuban coastal sharks, by using the tabulated K method.

Materials and methods: Using ten consecutive lots, an analysis was carried out of parameters such as specific weight, refractive indexes, acidity, saponification, peroxide, unsaponifiable matter, and vitamin A and palmitic acid content. The distribution and randomness of the data was assessed. Then, the quality specification limits were calculated, for a 95% degree of confidence.

Results: The values obtained in the assessment of physical and chemical parameters demonstrated the quality of the oil, by adhering to the normal distribution and randomness of data, with probability values above 0,05.

Conclusions: Using the tabulated K method were established unilateral quality specification limits to index of acidity and vitamin A and palmitic acid content, while to specific weight, refractive indexes, saponification, peroxide and unsaponifiable matter were bilateral. The assessed lots of pool shark-liver oil have adequate quality, considering the results of the evaluated parameters. The properties of the assessed lots showed a high degree of compliance.
