Application of near-infrared spectroscopy in the sugar industry for the detection of betaine

Seeking for non‐friendly chemical elements in tabletop sugar and zero to low‐calorie sweetener sachets

“…For tabletop sugar sweeteners, the FT-IR results (Figure 1) are typical from sucrose, 13,[19][20][21] the main sugar component. However, 1644 cm À1 absorption band, which can be associated with silica (silicon dioxide [SiO 2 ]), 22,23 was also detected in 6 samples, independently if the sample is white or brown sugar.…”

“…For tabletop zero-calorie and low-calorie sweeteners, the FT-IR results (Figure 4) are quite complex. A major part of samples ($92%) present absorption bands typical of sucrose ($46%) 13,[19][20][21] or lactose ($46%), 21 which is worrisome, since a person with diabetes or with lactose intolerance could be not allowed to consume such zerocalorie and low-calorie sweeteners. The quantity of sucrose and lactose in analyzed samples was $55% and $54%, respectively.…”

Semitransparent near-infrared Sn–Pb hybrid perovskite photodetectors

“…4 As these technologies evolve, so does the need for the design and fabrication of novel devices for new applications. For instance, near-infrared (NIR) photodetectors are required for applications such as vein recognition, 5 pulse oximetry, 6 brain imaging, 7 proximity sensors, 8 spectrometry for food monitoring 9 or skin cancer diagnosis. 10 Other applications require the integration of the imager in front of a display (such as phones, computers, or ATMs), where semitransparent devices are needed.…”

Control system for continuous soaking process in sugar refinery

“…So, a new control method that provides adequate quality optimization is needed and the corresponding control problem for the CSP must be solved [1].…”
