“…Table 3 shows that 30°C room temperature and lower pH levels yielded the highest amount of curcumin. The amount of curcumin rose from 91.17 to 110.41 mg/gm between 4o C and 30o C [50][51][52].…”

The demand for natural and healthier food products has increased dramatically in recent years due to growing consumer awareness of the impact food has on health as well as evidence of adverse effects from various ingredients, including some additives. This study evaluates the extraction method, solvent effects, precipitation, identification, purification, and lycopene, carotene, and curcumin content from turmeric, carrot, and tomato. Along-side, tomato, carrot, and turmeric samples were subjected to two different extraction and purification processes: solvent extraction for lycopene and carotene, and alkalization for curcumin. The samples were extracted and purified at room temperature (30ºC) and chilled (4ºC) for a period of three weeks. Tomato extracts had lycopene contents ranging from 0.0153 to 0.0362 mg/100g. obtained carotene content, which was then extracted using a solvent in the range of 61.43 to 81.72 mg/100g. The alkalization process produced a curcumin concentration of 91.17 to 110.41 mg/100g. Comparing the ethyl acetate extraction technique to the anti-solvent method, a greater amount of lycopene (red) and carotene (orange) precipitation was obtained. The maximum amount of curcumin precipitation obtained in lower pH solution. Lower pH is important to maintain the stability of curcumin precipitation. The experience of this research work suggested that lycopene from tomatoes, carotene from carrots, and curcumin from turmeric might be an excellent source to meet the increasing need for natural colorants.

“…In most studies, mixtures of acetone, ethanol/methanol, and hexane are used for the extraction of carotenoids from various matrices, but ethanol and acetone prove to be very efficient when large amounts of water are present, as in algal samples. In terms of safety and environmental protection, these two solvents are also the best choices for food applications [11][12][13][14][15].…”

Recently, the isolation and identification of various biologically active secondary metabolites from algae have been of scientific interest, with particular attention paid to carotenoids, widely distributed in various photosynthetic organisms, including algal species. Carotenoids are among the most important natural pigments, with many health-promoting effects. Since the number of scientific studies on the presence and profile of carotenoids in algae has increased exponentially along with the interest in their potential commercial applications, this review aimed to provide an overview of the current knowledge (from 2015) on carotenoids detected in different algal species (12 microalgae, 21 green algae, 26 brown algae, and 43 red algae) to facilitate the comparison of the results of different studies. In addition to the presence, content, and identification of total and individual carotenoids in various algae, the method of their extraction and the main extraction parameters were also highlighted.

“…Acetone is one of the most effective solvents for extracting violanthin, lutein, zeaxanthin, and β-carotene from microalgae. 31 The combination of organic solvents with other substances is also the focus of research. Enzyme-assisted aqueous two-phase extraction (EA-ATPE) using an ethanol/ ammonium sulfate system was investigated for total polyphenol (TP) and lutein from marigold flowers, and such experiments have also achieved good results.…”

Lutein, [(3R,3′R,6′R)-β,ε-carotene-3,3′-diol], is a C40 hydroxyl carotenoid. Its chemical structure is based on an unsaturated polyene chain skeleton, and there are one ε-ring and one β-ring on both sides of the skeleton, with a hydroxyl group on the 3′ site of each ring. Lutein is one of the important lipophilic isoprenes from mainly plants and algae. The wide range of sources makes the study of lutein quite comprehensive. The biosynthetic pathway and biochemical activities of lutein have been extensively studied and revealed. Lutein has been extensively studied for its important bioactivity, including for use in functional foods and medicines for brain health, eye-related diseases, skin health, and cancers. This review of lutein summarizes the major studies on bioactivity, metabolism, stability, digestive absorption, lutein delivery systems, and biotechnology.
