“…Vitamin C extraction was conducted according to the methodology described by Silva et al, [18], and vitamins D3 and E according to the methodology proposed by Ruiz-Ruiz et al, [19], modified by inclusion treatment through ultrasound (40 kHz) during 20 min, for the samples treated with hexane. Vitamin C quantification was performed through high-resolution liquid chromatography (H-RLC) (Shimatzu Prominence 20A), using a column in reverse phase (C18 -5 µm, 4.6 mm x 250 mm), diode array detector, mobile phase: KH2PO4 0-02 M pH = 3.00 (Ortho-Phosphoric Acid 85%), flow: 1 mL/min, furnace temperature of 35 ºC, 244nm wavelength and injection volume of 5 µL.…”

Degradation kinetic parameters in vitamins and antioxidants in coconut powder fortified with functionally active compounds (CP+FAC) during storage represents a valuable tool to predict the product’s shelf life. The aim of this research was to evaluate the degradation kinetics during storage of vitamins (C, D3, and E), total phenols, and properties associated to antioxidant activity. Vitamins were quantified via high-resolution liquid chromatography and the antioxidant activity through DPPH and ABTS free radical scavenging activity. An experimental design was used with two-factor factorial design: 1) storage time (tS) and 2) treatment: temperature (TA) - type of packaging (N2 and atmospheric air), where the dependent variables were adjusted to zero-, first-, and second-order kinetic models. In general, losses of FAC were significant with respect to the factors evaluated and their interactions, with minor changes at lower TA and packaged with N2, indicating that the degradation kinetics of the FAC is slower under these storage conditions. Increased storage temperature reduced FACstability, where the Arrhenius equation was able to quantify the effect of temperature of the rate of deterioration reactions of the FAC.
