Material and scope of measurements
Analysis of fruit from Coahuila separated the peel from the portion comprising pulp with seeds. Measurements in the dried material included fibre, protein and polyphenols, while extracts were assessed for activity in DPPH, ABTS and FRAP tests. These are results concerning the composition and chemical reactivity of the preparations, useful in studies of a food raw material. [Coutiño Laguna et al. 2022]
What DPPH, ABTS and FRAP tests mean
The extract tests assessed reactions with reagents in defined chemical systems. Results depend on the fruit fraction, sample preparation and assay conditions. Combined with basic composition, they help characterise the raw material and select a fraction for further technological studies. [Coutiño Laguna et al. 2022]
The study analysed dried material from Coahuila. Measurements of polyphenols and the chemical reactivity of the extract concern a laboratory sample. Applying these data to product properties requires consideration of preparation, the proportions of individual fruit parts and the way the result is expressed. [Coutiño Laguna et al. 2022]
