“…In other words, the presence of anthocyanins in potato tubers may mark also an increment of additional beneficial phenolic compounds, including CGAs, due to the upregulated activity of the same transcriptional regulator. According to de Andrade Lima et al [31], tuber peel largely contributes to total phenolic compounds. In our samples, peels contributed 30% to the total amount of CGA detected, especially in the tubers of colored varieties (i.e., Magenta Love, Scano di Montiferro and Violet Queen).…”

Potato is a staple food crop and an important source of dietary energy. Its tubers contain several essential amino acids, vitamins, minerals and phytochemicals that contribute to the nutritional value of this important product. Recently, scientific interest has focused on purple and red potatoes that, due to the presence of anthocyanins, may be considered as natural powerful functional food. The aim of this study was to evaluate the characteristics of pigmented varieties, the types of anthocyanins accumulated and the level of both beneficial phytochemicals (vitamin C and chlorogenic acids, CGAs) and anti-nutritional compounds (glycoalkaloids) following various cooking methods. The analyses described the presence of a mix of several acylated anthocyanins in pigmented tubers along with high level of CGA. The amount of antioxidants was differently affected by heat treatments according to the type of molecule and the cooking methods used. In some cases, the beneficial compounds were made more available by heat treatments for the analytical detection as compared to raw materials. Data reported here describe both the agronomic properties of these pigmented varieties and the effects of food processing methods on bioactive molecules contained in this natural functional food. They may provide useful information for breeders aiming to develop new varieties that could include desirable agronomical and industrial processing traits.

Green extraction techniques are more and more relevant due to major sustainable goals set by the United Nations. Greener extraction processes are being designed through the use of unconventional extraction techniques and green solvents, resulting in less hazardous processes which, consequently, reduces environmental impacts. This is also in line with the main principles of green chemistry. Additionally, greener extraction techniques intend to solve different drawbacks that are often related to conventional extraction techniques such as the high environmental impact. Biorefineries are a major player in developing greener extraction processes. These facilities take full advantage of several biomass sources, such as food waste, microalgae, and lignocellulosic biomass, in order to create high-value products, energy, alternative fuels, and bioactive compounds. Herein, a state-of-the-art review is presented, focused on presenting the greenest and least hazardous extraction processes that have been reported on the main biomass sources of a biorefinery—food waste, microalgae, and lignocellulosic biomass. Bioactive compounds such as phenolic compounds, bioactive pigments, and fatty acids are important in several sectors, mainly, the health, pharmaceutical, and agro-food sectors. Moreover, the bioactive compounds obtained through the aforementioned biomass sources and the different extraction procedures used will be presented and the authors will attempt to discuss, compare, and provide information about the most effective extraction techniques for each compound. Therewith, this review article should serve as a guide for industries, academics, and biorefineries in the future development of optimized and greener extraction procedures. Such analysis is lacking and could be very helpful for future research biorefinery projects since it tackles all of the major biomass sources of a biorefinery in a review article. To the best of our knowledge, this brings a novelty to the scientific community.

Supercritical carbon dioxide (SC‐CO2) is CO2 that is stored beyond its critical point of 7.4 MPa and 31.1 °C. Given the request for consumption of a green solvent for the environment, SC‐CO2 is widely utilized in chemical, food, and pharmaceutical industries. To design material and drug production processes using supercritical fluid (SCF) technology, knowledge of their solubility is important. Temperature and pressure are the main factors in the study of solubility. Solubility data are then evaluated using equation of state, semi‐empirical, and intelligence models to establish suitable correlations. SC‐CO2 is one of the most important materials used in SCFs to study solubility. Another application of SC‐CO2 is in the field of material extraction to reduce the consumption of organic solvents. Nanoparticles production in drug industry is another advantage of SC‐CO2. Micro and nanoparticles can be produced using SCF techniques. In this review, the applications of SC‐CO2 in drug solubility, extraction of valuable materials, and nanoparticles production for pharmaceutical processes are reported and discussed. Finally, the main challenges are explained.
