“…As previously reported in Table 2, all of the calibration models had high R 2 range; R 2 = 0.96-0.98. These values were within the ranges reported by other authors; R 2 = 0.95-0.98 for β-carotene [30], R 2 = 0.95 for α-tocopherol [31] and R 2 = 0.98 for l-ascorbic acid [32]. RPD values were also satisfactory.…”

Mango fruits contain substantial vitamins and dietary fibre. Vitamins vary among and within fruits depending on cultivar type and ripening stage. Conventional techniques of vitamins analysis are based on High Pressure Liquid Chromatography, which are costly and laborious. This study evaluated the potential of Fourier transform infrared-diffuse reflectance spectroscopy (FTIR-DRIFTS) technique in predicting β-carotene, α-tocopherol and l-ascorbic acid in pulps of four mango cultivar types ('Apple' , 'Kent' , 'Ngowe' , and 'Tommy Atkins'). Combination of ran dom forest (RF) and first derivative spectra developed the predictive models. Factorial ANOVA examined the interaction effect of cultivar type, site ('Thika' , 'Embu' and 'Machakos), and fruit canopy position (sun exposed/within crown) on β-carotene, α-tocopherol and l-ascorbic acid contents. RF Models gave R 2 = 0.97, RMSE = 2.27, RPD = 0.72 for β-carotene; R 2 = 0.98, RMSE = 0.26, RPD = 0.30 for α-tocopherol and R 2 = 0.96, RMSE = 0.51, RPD = 1.96 for l-ascorbic acid. Generally cultivar type affected vitamin C, F (3, 282) = 7.812, p < 0.05. Apple and Tommy Atkins had higher mean vitamins than Ngowe and Kent. In Machakos, within canopy fruits had higher β-carotene than sun-exposed fruits, F (5, 257) = 2.328, p = 0.043. However, interactions between fruit position, site and cultivar did not affect α-tocopherol and vitamin C. In Thika, Tommy Atkins at fully ripe stage had higher vitamin C than at intermediate maturity stage, F (2, 143) = 7.328, p = 0.01. These results show that FTIR-DRIFTS spectroscopy is a high-throughput method that can be used to predict mango fruit vitamins of in a large data set.

“…Near-infrared spectroscopy is a technique extensively used in agriculture for the determination of the quality of grain, fruits, vegetables, meat, among other agricultural products. Several studies are described in the literature reporting the use of NIRS for the determination of natural antioxidants: total carotenoids [226]; individual carotenoids such as lycopene and lutein [227,228]; β-carotene [228]; malvidin-3-glucoside and tannins [229]; and polysaccharides [230]. In other studies, Pissard et al [231] and Blanco-Díaz et al [232] also determined ascorbic acid using NIRS.…”

“…Similar infrared ranges have been used to measure maize pigments (Brenna and Berardo, 2004) and lutein and ␤-carotene in Chinese kale (Chen et al, 2009). Brenna and Berardo (2004) found that 1168 nm was an important wavelength for lutein determination in maize, whereas Chen et al (2009) found that the key wavelength was 2176 nm. However, a reflectance spectrum is difficult to interpret because there are few regions of the spectrum where the absorbance can be associated to only one type of functional group (Foley et al, 1998;Dian et al, 2008).…”
