GARCIA PENA, Caridad Margarita et al. EVALUATION AND OF THE QUALITY SPECIFICATIONS OF THE CUCURBITA PEPO LIPID EXTRACT. Rev. CENIC Cienc. Quím. [online]. 2022, vol.53, n.2, pp. 216-225.  Epub 15-Jul-2022. ISSN 2221-2442.

The objective was to experimentally determine the quality specification limits for the Cucurbita pepo lipid extract, by using the tabulated K method. Using ten consecutive lots, an analysis was carried out of parameters such as specific weight, refractive indexes, acidity, saponification, peroxide, and fatty acid content (palmitic, stearic, oleic and linoleic). The distribution of the data was assessed. Then, the quality specification limits were calculated, for a 95% degree of confidence. The values obtained in the assessment of physical and chemical parameters demonstrated the quality of the extract, by adhering to the normal distribution of data, with probability values above 0.05. Using the tabulated K method were established unilateral quality specification limits to index of acidity and peroxide, fatty acid content, while to specific weight, refractive and saponification indexes were bilateral. The assessed lots of Cucurbita pepo lipid extract have adequate quality, considering the results of the evaluated parameters. The properties of the assessed lots showed a high degree of compliance.
