“…If we compare this with the ABTS results, it can be said that the total phenolic content is directly proportional to the antioxidant capacity shown by the films (Table 3). Increasing total phenolic matter with an increasing amount of extract indicates that films have antioxidative properties and this feature is directly proportional to the amount of extract (Şahin et al, 2019). According to these results, the films containing the most phenolic substances are the films containing Prunella grandiflora extracts.…”

In this study, the production, characterization, antioxidant capacity, and antibacterial activity of chitosan‐based edible and biodegradable films prepared with the Prunella grandiflora (PG), Prunella laciniata (PL), Prunella orientalis (PO), and Prunella vulgaris (PV) extracts were investigated. For extraction, Prunella L plants were placed in 70% (v/v) ethanol solution and extracted in a mixer. For the production of the films, 1, 5, and 10 ml extracts were mixed with a 1% (w/v) chitosan solution containing 1% (v/v) glacial acetic acid solution and after adding glycerol, the solutions were allowed to dry. Some physical and surface properties (solubility, water vapor permeability, swelling ratio, moisture content, thickness, FTIR, and SEM analysis) of the films were determined and each of them were found to be compatible with the literature. Phenolic compounds (rosmarinic acid, protocatechuic acid, caffeic acid, rutin, and chlorogenic acid) were quantitatively determined in films by HPLC‐DAD. Practical applications This study proved the antioxidant and antimicrobial properties of four different Prunella L. extract incorporated in films. Chitosan edible films have a homogeneous structure, color transparency, and had antioxidant and antibacterial properties that are desired in food and packaging applications. The results confirm that the Prunella‐chitosan films can be used as an active package material.

“…The primary advantages are shortening the extraction time, improving extraction efficiency, a wide application, and simple operation [ 98 ]. Sahin et al [ 99 ] used the ultrasound-assisted extraction of lutein and carotenoids from Chlorella, added them to chitosan to prepare chitosan films, and characterized them using Fourier transform infrared spectroscopy and SEM technology. The results display how 4.844 ± 0.78 mg/g lutein and 0.533 ± 0.06 mg/g carotenoids can be prepared using ultrasonic extraction.…”

Natural plant pigments are safe and have low toxicity, with various nutrients and biological activities. However, the extraction, preservation, and application of pigments are limited due to the instability of natural pigments. Therefore, it is necessary to examine the extraction and application processes of natural plant pigments in detail. This review discusses the classification, extraction methods, biological activities, and modification methods that could improve the stability of various pigments from plants, providing a reference for applying natural plant pigments in the industry and the cosmetics, food, and pharmaceutical industries.

“…Additionally, the carotenoid in C. vulgaris extracts, in particular, can be used to make bio‐based plastic for food packaging. Lutein, α‐carotene, and β‐carotene were isolated from C. vulgaris , and it was demonstrated that the addition of carotenoids to chitosan film considerably enhanced the film and demonstrated its suitability for use as a packaging material due to its antioxidative qualities (Şahin et al, 2019). Hence, new investigations in terms of utilization of C. vulgaris extracts in bio‐based plastic are needed and how the extracts affect the mechanical and thermal properties of the bioplastics along with their effects on the shelf life of the packed products if they were used for packaging.…”

Environmental pollution is a big challenge that has been faced by humans in contemporary life. In this context, fossil fuel, cement production, and plastic waste pose a direct threat to the environment and biodiversity. One of the prominent solutions is the use of renewable sources, and different organisms to valorize wastes into green energy and bioplastics such as polylactic acid. Chlorella vulgaris, a microalgae, is a promising candidate to resolve these issues due to its ease of cultivation, fast growth, carbon dioxide uptake, and oxygen production during its growth on wastewater along with biofuels, and other productions. Thus, in this article, we focused on the potential of Chlorella vulgaris to be used in wastewater treatment, biohydrogen, biocement, biopolymer, food additives, and preservation, biodiesel which is seen to be the most promising for industrial scale, and related biorefineries with the most recent applications with a brief review of Chlorella and polylactic acid market size to realize the technical/nontechnical reasons behind the cost and obstacles that hinder the industrial production for the mentioned applications. We believe that our findings are important for those who are interested in scientific/financial research about microalgae.
