“…The assessment of the color maintenance through the analysis of chromaticity parameters is used along with other techniques to estimate the effectiveness of these strategies. When proteinaceous substrates are used, their own fluorescence has also been used to monitor their association with anthocyanin molecules [99][100][101][102].…”

Organisms belonging to all life kingdoms may have the natural capacity to fluoresce. Autofluorescence events depend on the presence of natural biomolecules, namely endogenous fluorophores, with suitable chemical properties in terms of conjugated double bonds, aromatic or more complex structures with oxidized and crosslinked bonds, ensuring an energy status able to permit electronic transitions matching with the energy of light in the UV-visible-near-IR spectral range. Emission of light from biological substrates has been reported since a long time, inspiring unceasing and countless studies. Early notes on autofluorescence of vegetables have been soon followed by attention to animals. Investigations on full living organisms from the wild environment have been driven prevalently by ecological and taxonomical purposes, while studies on cells, tissues and organs have been mainly promoted by diagnostic aims. Interest in autofluorescence is also growing as a sensing biomarker in food production and in more various industrial processes. The associated technological advances have supported investigations ranging from the pure photochemical characterization of specific endogenous fluorophores to their possible functional meanings and biological relevance, making fluorescence a valuable intrinsic biomarker for industrial and diagnostic applications, in a sort of real time, in situ biochemical analysis. This review aims to provide a wide-ranging report on the most investigated natural fluorescing biomolecules, from microorganisms to plants and animals of different taxonomic degrees, with their biological, environmental or biomedical issues relevant for the human health. Hence, some notes in the different sections dealing with different biological subject are also interlaced with human related issues. Light based events in biological subjects have inspired an almost countless literature, making it almost impossible to recall here all associated published works, forcing to apologize for the overlooked reports. This Review is thus proposed as an inspiring source for Readers, addressing them to additional literature for an expanded information on specific topics of more interest.

In this study, the effect of different wall materials on the stability of anthocyanins and some physicochemical properties of the encapsulated juice of seedless black barberry were investigated. A response surface methodology was used to analyze and predict the physicochemical properties of microcapsules. In order to perform the microencapsulation, a spray dryer with an inlet temperature of 130°C, an outlet temperature of 80°C, and an airflow rate of 600 L/hr was used. In this study, independent factors were maltodextrins (0%, 7.5%, and 15% (w/v)), Arabic gum (0%, 3%, and 6% (w/v)), and whey protein concentrate (0%, 8%, and 16% (w/v)). Second‐order polynomial models with high R2 (0.90–0.99) values were proposed for each physicochemical property, including yield, total anthocyanin content, total phenolic content, antioxidant activity (EC50), moisture, bulk density, and porosity. Scanning electron microscopy and differential scanning calorimetry were used to study the microstructural and the thermal properties of encapsulated powders with an optimum wall material composition. Results showed that the optimum concentrations for each wall material were 13.41% (w/v) of maltodextrins, 5.51% (w/v) of Arabic gum, and 15.09% (w/v) whey protein concentrate. Novelty impact statement Microencapsulation of the anthocyanin compounds of seedless black barberry by using a combination of different carriers as wall materials was done for the first time in this research.

“…In order to know bio stabilization of anthocyanins extract from purple flesh cultivated potato, a study was addressed on the encapsulation anthocyanins' efficiency and bioaccesibility. The anthocyanin extract from INIA purple flesh potato (PPE) was micro-encapsulated by spray-drying [29] (Figure 1). Maltodextrin (MD) was used as the encapsulating agent, due to its high solubility in water, low viscosity, bland flavor, and colorlessness.…”

The potato is the fourth most important crop in the world in terms of human food, after maize, wheat and rice (FAOSTAT, 2019). The cultivated potato is a vital food-security crop considering its worldwide growth, from latitudes 65° Lat N to 53° Lat S, high yield, and great nutritive value. The potato is a good source of dietary energy and micronutrients, and its protein content is high in comparison with other roots and tubers. The cultivated potato is also a concentrated source of vitamin C and some minerals such as potassium and magnesium. Tuber flesh color generally ranges from white to dark yellow in cultivated potato; however, the high potato diversity shows tuber flesh color varies from white to dark purple. Red and purple-flesh potatoes are an interesting alternative for consumers due to phenolic compounds and antioxidant capacity. The goal of this publication is to show the advances in red and purple flesh potato, in terms of anthocyanin profile, color extraction and stability in simulated in vitro digestion.
