“…To identify and quantify specific toxic substances in mixtures using PLS regression and multivariate analysis with Raman spectroscopy and FTIR, two sets of ternary mixtures (crack, caffeine, and sodium carbonate; crack, lidocaine, and sodium carbonate) at different concentrations were analyzed according to a simplex‐centroid design . The concentrations are shown in Table .…”

The use of chemicals is often related to suicide attempts and acute poisoning, which account for a significant number of hospital admissions. The differential diagnosis of patients exposed to poisoning is intricate and varies according to the substance used. The identification of drugs and drug abuse in cases of poisoning often requires time‐consuming and complex techniques, such as chromatography. The use of vibrational spectroscopy such as Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR) enables the quick identification of toxic substances using no reagents or markers. This study aims to apply these techniques in the long term to identify and quantify substances found at the locations of suicide attempts, poisonings, and even drug consumption sites, including crack samples containing a cocaine base and adulterants commonly seized in drug busts, such as caffeine, lidocaine, and sodium carbonate. In this study, Raman and FTIR spectra of ternary mixtures of crack with caffeine and sodium carbonate and crack with lidocaine and sodium carbonate were obtained. These spectra were used for building multivariate models based on partial least squares (PLS) for determining the composition of the samples quantitatively. High correlation coefficients (r > 0.98) and small cross‐validation prediction errors (< 6%) were obtained for both Raman and FTIR spectral models. The results showed that PLS regression enables crack quantification in ternary mixtures using both Raman and FTIR spectroscopy, allowing for quick medical intervention or determination of the cause of death in cases of cocaine toxicity.

“…In several juices, the applications of the MDs were in functional fruit juices [24,[67][68][69][70][71][72][74][75][76], powders [66,73], and the quality of sugarcane [77] juice. In addition, the MDs have often been applied in formulations of probiotic and energetic functional juices to improve these products' sensory, antioxidant, and nutritional properties with potential benefits for consumers' health [66,68,72,73]. Among the most common uses of MDs in several juices, there were reports of studies that evaluated the reduction in calories in juices [67], the addition of stevia [74], and the inclusion of phenolic and bioactive compounds in juices [71].…”

Design of Experiments (DoE) is a statistical tool used to plan and optimize experiments and is seen as a quality technology to achieve products excellence. Among the experimental designs (EDs), the mixture designs (MDs) stand out, being widely applied to improve conditions for processing, developing, or formulating novel products. This review aims to provide useful updated information on the capacity and diversity of MDs applications for the industry and scientific community in the areas of food, beverage, and pharmaceutical health. Recent works were selected following the Preferred Reporting Items for Systematic Review and Meta-Analyses statement (PRISMA) flow diagram. Data analysis was performed by self-organizing map (SOM) to check and understand which fields of application/countries/continents are using MDs. Overall, the SOM indicated that Brazil presented the largest number of works using MDs. Among the continents, America and Asia showed a predominance in applications with the same amount of work. Comparing the MDs application areas, the analysis indicated that works are prevalent in food and beverage science in the American continent, while in Asia, health science prevails. MDs were more used to develop functional/nutraceutical products and the formulation of drugs for several diseases. However, we briefly describe some promising research fields in that MDs can still be employed.

“…The same pair of antioxidants can show different effects, depending on the reaction environment, their mutual quantitative relationships, and the presence of other ingredients in the mixture [26]. Therefore, the measurement of components isolated from natural sources does not allow knowing the total antioxidant capacity of a product, due to the combined and synergistic effect of a large number of compounds [27,28]. Previous studies have found that concentration and proportion were the main factors affecting the interaction between antioxidants [29].…”

The increasing world population entails a great necessity to produce large amounts of food, leading to an increase in organic waste. Unlike traditional agriculture, based on the circular sustainability, modern agriculture produces tons of residues, which are accumulated in landfills or, in some cases, burnt. Numerous studies have demonstrated that agricultural residues are rich in bioactive compounds, particularly phenolic compounds, with antioxidant properties. Antioxidant activity has been widely related with protective effects and prevention potential for different diseases. Also, the scavenging and protective effects of antioxidant compounds have shown a connection and synergistic effect with other biological properties, such as anti-inflammatory, anti-tumor, anti-aging, neuroprotective, cardioprotective, or antidiabetic. These compounds can be applied in several fields, including food, cosmetic, and pharmaceutical industry. This chapter will be focused on the interconnected bioactive properties and possible applications of plant-origin compounds with antioxidant potential to valorize different agricultural waste.
