“…For example, its biomass can be useful for producing energy [19][20][21][22]. Stalks and leaves have high calorific value [23] and they are efficient solid biofuels after forming in bales [24]. Moreover, stems and grain are a feedstock for bioethanol production [23,[25][26][27][28].…”

“…Continuous global warming and further development of genetic engineering make sorghum cultivation possible and profitable also in Poland, where sorghum was mainly used by the feed industry. But now, the grain can be produced successfully [23,34]. 1 3 In terms of chemical composition, sorghum is essentially similar to maize and millet [5,[34][35][36][37][38][39][40].…”

Sorghum is the fifth most important cereal in the world in terms of the cropped area. It is mainly grown for feeding animals and it is also used in the food industry. Sorghum grain is generally a rich source of antioxidants such as polyphenols and carotenoids. For this reason, it is considered as a good source of bioactive food components and it has health-promoting properties. Sorghum is a gluten-free cereal grown in many regions worldwide, primarily in the tropical and subtropical regions. However, new hybrids and forms of sorghum are capable to produce seeds also in temperate climate. The aim of this study was to conduct the influence of weather conditions on bioactive compound content in sorghum grain. The quantitative analysis of selected bioactive compounds, such as phenolic acids, flavonoids, carotenoids, and phytosterols, was carried out. The tested material comprised grain of two varieties: ‘Sweet Susana’ and ‘Sweet Caroline’, which have different color of grain: red and white. The research material was obtained from growing seasons 2016–2018. Quantitative analysis of free phenolic acids, total carotenoids, and total phytosterols was performed by ultra-performance liquid chromatography (UPLC) after prior basic hydrolysis followed by acid. An ultra-efficient liquid chromatograph coupled with an absorption-based detector (UPLC-PDA) was used for these analyses. The results showed the variability of the content of bioactive compounds depending on weather conditions.

“…9 As a cost-effective, adaptable crop for semiarid regions of the U.S., grain sorghum ( Sorghum bicolor (L.) Moench) also has a good potential as a feedstock for fuel ethanol production. 10–15 Due to its genetic diversity, wide range of adaptability and inherent drought and heat tolerance, sorghum can also be tailored to fit the renewable strategies being proposed through genetic manipulation and crop management. 15–18…”

In the sorghum-growing regions of the U.S., some bioethanol plants use mixtures of corn and sorghum grains as feedstocks depending on price and availability. For regulatory purposes and for optimizing the ethanol manufacturing process, knowledge of the grain composition of the milled feedstock is important. Thus, a near infrared spectroscopy method was developed to determine the content of sorghum in corn–sorghum flour mixtures. Commercial corn and sorghum grain samples were obtained from a bioethanol plant over an 18-month period and across two crop seasons. An array of corn–sorghum flour mixtures having 0–100% sorghum was prepared and scanned using a near infrared spectrometer in the 950–1650 nm wavelength range. A partial least squares regression model was developed to estimate sorghum content in flour mixtures. A calibration model with R2 of 0.99 and a root mean square error of cross validation of 3.91% predicted the sorghum content of an independent set of flour mixtures with r2 = 0.97, root mean square error of prediction = 5.25% and bias = −0.49%. Fourier-transform infrared spectroscopy was utilized to examine spectral differences in corn and sorghum flours. Differences in absorptions were observed at 2930, 2860, 1710, 1150, 1078, and 988 cm−1 suggesting that C–H antisymmetric and symmetric, C=O and C–O stretch vibrations of corn and sorghum flours differ. The regression coefficients of the near infrared model had major peaks around overtone and combination bands of C–H stretch and bending vibrations at 1165, 1220, and 1350 nm. Therefore, the above results confirmed that sorghum content in corn sorghum flour mixtures can be determined using near infrared spectroscopy.
