TL;DR: In this article, a detailed procedure for testing linearity of calibration curves in method validation by the OLS method, including experimental design, estimation of the parameters, outlier treatment and evaluation of the assumptions, was proposed.

TL;DR: In this article, the use of rice flour corn and cassava starch was evaluated in several formulations aiming to find a flour mixture to replace wheat flour in the production of free-gluten white bread.

TL;DR: In this article, the effects of high hydrostatic pressure on the sensory properties of passion fruit juice by quantitative descriptive analysis (QDA) were investigated, which revealed high similarity among juice sensory attributes from in natura and pressurized samples both differing from commercial ones.

TL;DR: The most productive strain, identified as Colletotrichum gloesporioides, produced 27,700 U/l of lipase under optimized conditions and the crude lipase preparation was capable of hydrolysing a broad range of substrates including lard, natural oils and tributyrin.

TL;DR: A sequential strategy was proposed to detect adulterants in milk using a mid-infrared spectroscopy and soft independent modelling of class analogy technique, providing 82% correct classifications, 17% inconclusive classifications and 1% misclassifications.
