“…In addition, XRD analysis was conducted to evaluate the crystalline nature of mediated SeNPs based on the emission peaks of 2θ = 22.12°, 24.72°, 31.98°, 33.18°, and 45.19°corresponding to the Se crystal planes ( 100), ( 101), ( 102), ( 110), and ( 111), respectively, as can be shown in Figure 1c that was confirmed by a previous studies (Aman Mohammadi et al, 2021;Kazemi et al, 2021). FESEM was used to describe the morphology and distribution size of SeNPs synthesized from fruit extract.…”

Biogenic synthesis of selenium nanoparticles (SeNPs) using plant extracts has emerged as a promising alternative approach to traditional chemical synthesis. The current study aims to introduce a safe, low-cost, and green synthesis of SeNPs using fresh fruit extract of Vaccinium arctostaphylos L. The biogenic synthesis of SeNPs was confirmed by different analyses including ultraviolet-visible spectrophotometry, Fourier transform infrared, and energy-dispersive X-ray. Also, the crystalline nature, size, and morphology of the obtained SeNPs were characterized by X-ray diffraction, dynamic light scattering, field emission scanning electron microscopy, and transmission electron microscopy techniques. The SeNPs were successfully synthesized with fruit extract of V. arctostaphylos L. in a regular spherical form and narrow size distribution with suitable zeta-potential values and exhibited appropriate biocompatibility. It revealed that the synthesized SeNPs can significantly inhibit the growth of 4T1 breast cancer cells with an IC 50 of ∼84.19 ± 25.96 µg/ml after 72 h treatment. Overall, it can be concluded that the green synthesized SeNPs can be attractive, nontoxic, and eco-friendly candidates for drug delivery or medicinal applications.

“…Many plants have medicinal properties and depending on the molecules in their chemical structure can have antibacterial or microbial properties. Many researchers have studied the antibacterial and antimicrobial properties of plants [4][5][6][7]. Antibacterial growth was investigated in woollen fabric with natural biopolymeric material (chitosan) and natural dyeing (turmeric and madder).…”

Nowadays according to more attention to natural products, the development of research on this issue seems necessary. Many plants are known around the world to have antibacterial, antimicrobial, and antifungal properties. By using those plant compounds, antibacterial, antimicrobial, and fungal properties can be created in textiles. Textiles are one of the unavoidable requirements that all human beings use abundantly in their lives. In the natural dyeing process, the use of some medicinal plant compounds resulted in antibacterial, antimicrobial, and antifungal properties. In this study, medicinal plants such as thyme, clove, marjoram, lavender, wormwood, and espand were studied for antibacterial and antimicrobial properties on textiles. The antibacterial property of mordanted and dyed wool & cotton yarns were tested against Escherichia coli (Gram-negative), Staphylococcus aureus (Gram-positive), and Candida albicans microbe for cotton. The range of colour developed on dyed materials was evaluated in terms of (L*, a*, b*) CIE LAB coordinates and the dye absorption concentration on the yarns was studied by using K/S values. Also, fastness tests on dyed samples for light and washing fastness were carried out. The experimental results showed that the examined plants, in addition to creating antimicrobial and antibacterial properties on wool and cotton yarns, can be used as a dye to produce a durable yellow shade. The dyeing fastness of applied dyes was acceptable. Aloe vera, which has a polyphenolic structure, was used to increase dyeing fastness and durability of antibacterial activity against gram-negative and gram-positive bacteria. The property was created to maintain its durability for several washed cycles.

“…In this context, pigments from natural sources such as plants (flowers, fruits, and leaves), animals (insects), and microorganisms (fungi, bacteria, yeasts, and algae) stand out because they act as dyes (Sudhakar et al, 2016;Muthusamy et al, 2020;Aman Mohammadi et al, 2022). The increase in demand for pigments can be associated with the consumer market's perception that this type of product is safer and more environmentally friendly (Kobylewski and Jacobson, 2012).…”

“…The increase in demand for pigments can be associated with the consumer market's perception that this type of product is safer and more environmentally friendly (Kobylewski and Jacobson, 2012). It is commonly reported that pigments are considered safe, non-toxic, non-carcinogenic, biodegradable, and of low risk to the environment (Wrolstad and Culver, 2012;Dikshit and Tallapragada, 2018) as they do not interfere with the aquatic biota, not showing an undesirable/harmful tendency toward allergic reactions, intolerances, in addition to other effects such as mutagenicity and potential carcinogenic effect (Dikshit and Tallapragada, 2018;Aman Mohammadi et al, 2022). However, like any other product available for use, natural pigments need to be extensively studied for toxicity and safety (Kobylewski and Jacobson, 2012), as several other widely used components have been banned due to proven adverse effects, including synthetic dyes such as ponceau, tartrazine, and sunset yellow, for example (Kobylewski and Jacobson, 2012;Poorniammal et al, 2021).…”

“…On the other hand, microbial pigments present higher yields, as well as simpler and cleaner extraction and purification processes compared with plant pigments. Pigments from microorganisms show no seasonal variation (as with pigments extracted from plant sources, for example), and demonstrate the possibility of improvements in the process to increase production yield and ease of scalability (Galaffu et al, 2015;Panesar et al, 2015;Aman Mohammadi et al, 2022;Bakhshi et al, 2022).…”

The demand for dyes from natural sources to substitute synthetic dyes for application in the food industry has been continuously increasing due to some synthetic dyes being associated with several problems, including hypersensitivity, carcinogenesis, and negative environmental impacts. Furthermore, dyes from natural sources (like pigments) are generally regarded by the consumer as safer or with fewer side effects—a fact that requires in-depth investigation—, which increases the commercial interest in such products. In this sense, great focus has been given to the biotechnological potential of Monascus sp. to produce red, orange, and yellow pigments using different types of the fermentation process (submerged or in solid-state fermentation), substrates, and process parameters (temperature, pH, agitation, aeration, etc.), aiming at optimizing and reducing costs in pigment production. In general, Monascus pigment has shown stability at neutral and basic pH, at elevated temperatures for a few hours, and to some metallic ions while not showing stability at acidic pH, elevated temperatures for many hours, and in the presence of light. Applications of Monascus pigment with colorant function in foods (candies, bread, yogurt, cheese, beer, and meat products) reported improvement in the color aspect by sensory analysis. The application of Monascus pigment still seems promising and incipient, demonstrating that it needs to be further studied, mainly concerning the stability of the pigment in vivo systems (inside the food) where adverse conditions are combined. Regulatory issues are heterogeneous around the world, which creates difficulties to expand production and commercialization but also demonstrates the need for studies to confirm its safety. In this sense, this mini-review presents the potential, strategies, and challenges of Monascus pigment for food application.
