“…A twoaqueous phase system consisting of DESs and alcohol was prepared to extract carotenoids from pumpkin peel with cellulase by ultrasound-assisted extraction. The Alga Tisochrysis lutea Fucoxanthin (22.03 mg/g dry weight) [41] The extraction solvent composed of DES (choline chloride/triethylene glycol (1:3)) and ethanol (6:4) showed the highest yield of 2.46% at the optimized ultrasonic extraction conditions, namely powder of 300 W for 40 min, solid/liquid ratio of 1: 40 g/mL, cellulase addition amount of 2.10% [32]. Noticeably, the yield of carotenoids from pumpkin peel decreased with the DES water content, as carotenoids are insoluble in water.…”

Carotenoids are used commercially for nutraceutical products because of their low toxicity, antioxidant activity, association with a reduction in various diseases and high coloring capacity. However, low stability and bioavailability limited their applications. Alterations in the physicochemical properties of carotenoids by Z-isomerization are beneficial for their extraction and bioavailability. The main strategies applied for enhancing their Z-isomerization include adding a catalyst, especially natural or heterogeneous sulfur-containing compounds. Consumers’ interest in products with carotenoids of natural origin has increased, which has emphasized a need for improved methods for their extraction from food waste. The green extraction methods for carotenoid recovery, especially using natural deep eutectic solvents combined with some novel extraction techniques showed a rapid increase and excellent application prospects. Health problems faced by the older population boost the demand for carotenoid diet supplements for skin health, anti-aging, treating eye disorders, preventing cancer (prostate) and obesity, thereby driving the growth of the carotenoids industry. However, the expansion of the carotenoid worldwide market is hampered by strict regulatory and approval standards. Relevant standards of carotenoids, especially Z-carotenoids, need to be improved.

“…Prodigiosin extraction from S. marcescens [205] was studied following this technique. However, it has also been studied for pigment extraction from sources other than microbial [206,207]. Few scientific articles report enzyme-assisted extraction methods for microbial pigments, suggesting an area to be explored in future research.…”

Microbial pigments have many structures and functions with excellent characteristics, such as being biodegradable, non-toxic, and ecologically friendly, constituting an important source of pigments. Industrial production presents a bottleneck in production cost that restricts large-scale commercialization. However, microbial pigments are progressively gaining popularity because of their health advantages. The development of metabolic engineering and cost reduction of the bioprocess using industry by-products opened possibilities for cost and quality improvements in all production phases. We are thus addressing several points related to microbial pigments, including the major classes and structures found, the advantages of use, the biotechnological applications in different industrial sectors, their characteristics, and their impacts on the environment and society.
