“…Nonetheless, flexirubin-type pigments exhibit other relevant bioactive properties, such as the antioxidant ability, which was also assessed. ABTS + radical scavenging assay is an electron transfer-based assay widely used for the assessment of the antioxidant capacities of natural products [ 80 , 81 , 82 , 83 ]. This spectrophotometric technique is based on ability of compounds to donate hydrogen to free radicals and thus the antioxidants reduce the ABTS + radical to a colorless compound [ 84 ].…”

A Bacterial Cellulose (BC) film was developed and characterized as a potential functional bioactive material. BC films, obtained from a microbial consortium of bacteria and yeast species, were functionalized with the bacterial pigment prodigiosin, produced by Serratia plymuthica, and flexirubin-type pigment, from Chryseobacterium shigense, which exhibit a wide range of biological properties. BC was successfully functionalized at 15% over the weight of the fiber at 40 °C during 60 min, and a color strength of 1.00 ± 0.01 was obtained for BC_prodigiosin and 0.38 ± 0.02 for BC_flexirubin-type pigment. Moreover, the BC films showed moderate hydrophilic character following alkaline treatment, which was maintained after both pigments were incorporated. The porosity and mechanical performance of the functionalized BC samples also remained unaffected. Furthermore, the BC samples functionalized with prodigiosin presented antibacterial activity and were able to inhibit the growth of pathogenic bacteria Staphylococcus aureus and Pseudomonas aeruginosa, with inhibition rates of 97.89 ± 0.60% and 85.12 ± 0.17%, respectively, while BC samples functionalized with flexirubin-type pigment exhibited the highest antioxidant activity, at 38.96 ± 0.49%. This research provides an eco-friendly approach to grant BC film-based material with color and advantageous bioactive properties, which can find application in several fields, especially for medical purposes.

“…The most used and efficient solvents for the extraction of anthocyanins are acidified organic solvents, such as water, acetone, ethanol and methanol. Their acidification is achieved with weaker organic acids, such as acetic acid, but hydrochloric acid can also be used, with the role of improving the stability of anthocyanins [ 84 ].…”

Anthocyanins: Factors Affecting Their Stability and Degradation

Anthocyanins are secondary metabolites and water-soluble pigments belonging to the phenolic group, with important functions in nature such as seed dispersal, pollination and development of plant organs. In addition to these important roles in plant life, anthocyanins are also used as natural pigments in various industries, due to the color palette they can produce from red to blue and purple. In addition, recent research has reported that anthocyanins have important antioxidant, anticancer, anti-inflammatory and antimicrobial properties, which can be used in the chemoprevention of various diseases such as diabetes, obesity and even cancer. However, anthocyanins have a major disadvantage, namely their low stability. Thus, their stability is influenced by a number of factors such as pH, light, temperature, co-pigmentation, sulfites, ascorbic acid, oxygen and enzymes. As such, this review aims at summarizing the effects of these factors on the stability of anthocyanins and their degradation. From this point of view, it is very important to be precisely aware of the impact that each parameter has on the stability of anthocyanins, in order to minimize their negative action and subsequently potentiate their beneficial health effects.

“…Fourth, Figure 1d anthocyanins memorably increased when ethanol concentration was in the range of 40%-60% (p < .05). This effect could be explained by the fact that a high ethanol concentration could help the solvent to penetrate into the cells of cranberry and increase the solubility of anthocyanins (Nistor et al, 2020). Nevertheless, once the ethanol concentration was over 60%, the yield of anthocyanins markedly decreased (p < .05), which was attributed to the reason that high ethanol concentration could increase the solubility of alcohol-soluble impurities and reduce the solubility of anthocyanins .…”

Cranberries (Oxycoccos) are mainly grown in the cold northern hemisphere (Massachusetts, Wisconsin, and Maine in the north of the United States). In addition, cranberries are also planted in the greater Khinganling region of China. Cranberry cultivation is deeply favored owing to its high nutritional value, unique aroma, and attractive red pigment (Sette et al., 2017). Cranberry, as a good source of bioactive compounds, includes anthocyanins, flavanols, various vitamins, superoxide dismutase, and phenolic acids .Anthocyanins, as one of the most essential active components in cranberry, are water-soluble natural pigments with high benefits for human health such as free radical scavenging (Jiao et al., 2018), antibacterial (Pertuzatti et al., 2016, inhibition cancer cell increment (Yun
