Quadratic effect of the protein content of a solid state fermented baby banana (<em>Musa acuminata</em> AA) treated with whey

Abstract

Graphical Abstract AbstractTo predict the protein content in a solid state fermented (SSF) baby banana (Musa acuminata AA) of waste inoculated with whey, using linear, quadratic, cubic, compound, exponential and logistic regression models. In SSF samples of 8 days post-processing, inoculated with 0, 1, 5 and 10 ml of whey/kg of mixture, the protein content of the SSF was determined. For data processing the SPSS version 22 software was used. A quadratic effect of the protein content was observed in the SSF of baby banana (R 2 = 0.99; Y = 6.372 + 2.003*X -0.138*X 2 ). In conclusion, the use of increasing doses of whey as an inoculant of the SSF of baby banana showed a quadratic effect on the protein content.
