Food spoilage is one of the key concerns in the food industry. One approach is the improvement of the shelf life of the food by introducing active packaging, and another is intelligent packaging. Detecting packed food spoilage in real-time is key to stopping outbreaks caused by food-borne diseases. Using active materials in packaging can improve shelf life, while the nonharmful color indicator can be useful to trace the quality of the food through simple color detection. Recently, bio-derived active and intelligent packaging has gained a lot of interest from researchers and consumers. For this, the biopolymers and the bioactive natural ingredient are used as indicators to fabricate active packaging material and color-changing sensors that can improve the shelf life and detect the freshness of food in real-time, respectively. Among natural bioactive components, carotenoids are known for their good antimicrobial, antioxidant, and pH-responsive color-indicating properties. Carotenoids are rich in fruits and vegetables and fat-soluble pigments. Including carotenoids in the packaging system improves the film’s physical and functional performance. The recent progress on carotenoid pigment-based packaging (active and intelligent) is discussed in this review. The sources and biological activity of the carotenoids are briefly discussed, and then the fabrication and application of carotenoid-activated packaging film are reviewed. The carotenoids-based packaging film can enhance packaged food’s shelf life and indicate the freshness of meat and vegetables in real-time. Therefore, incorporating carotenoid-based pigment into the polymer matrix could be promising for developing novel packaging materials.

“…[80] e major producer of this biomolecule is D. salina, which can accumulate up to 14% of this component as dry weight (up to 25 mg/L) under outdoor conditions. [140,141] D. salina production is currently at 1200 tons per annum in Australia, Israel, the USA, and Japan for the production of β-carotene. [142] Apart from those listed above, microalgae are also good producers of Vitamins B, C, and E, which are important to decrease fatigue, prenatal health problems, and antidiabetic compounds.…”

The world population is ever increasing and so is the need to ensure food security. Food production needs to increase by about 70% within the next 40 years to cater for food consumption. Moreover, with increasing collective consciousness toward food supplementation for improving quality of health, the development of nutraceuticals has gained prominence in disease prevention, treatment, and overall health improvement. However, due to the constant controversial debate of food production for consumption against other uses, the search for better alternatives led to microalgae. Species such as Spirulina, Chlorella, Scenedesmus, and Dunaliella, among many others, are important sources of primary and secondary metabolites that play crucial roles in disease prevention and treatment. Understanding the significance of nutraceuticals and how microalgae can be used to produce those value-added molecules is necessary for any potential commercial exploitation. This review discusses the potential of microalgae to be exploited as promising sources of nutraceuticals. Here, essential biomolecules used as nutraceuticals are explored and their crucial roles in disease prevention, especially cancer, cardiovascular diseases, and strengthening the immune system. The composition of microalgae, which makes them suitable candidates to produce nutraceuticals, is discussed. Furthermore, the multifarious aspects of microalgae cultivation, in terms of cultivation systems and factors affecting biomass production and productivity regarding nutraceutical production, are reviewed. The multiple sustainable facets of microalgae culture, which can help in carbon sequestration, fast biomass production, and boosting health benefits, should interest stakeholders and potential commercial producers. Bioprocessing of microalgae for the extraction and purification of microalgae-based products is also reviewed, focusing on the key methods of pre-treatment, extraction, and purification of microalgal biomass.

“…These pigments are synthesized by various microalgal species but the concentration in each microalga is dependent on the particular strain and their cultivation condition e.g. Dunaliella salina preferentially synthesize bcarotene and Hematococcus pluvialis predominantly synthesize astaxanthin (Khoo et al, 2019;Wolf et al, 2021).…”

Microalgal lutein biosynthesis: Recent trends and challenges to enhance the lutein content in microalgal cell factories

Photosynthetic organisms such as eukaryotic microalgae and prokaryotic cyanobacteria synthesize a wide range of valuable chemicals. They are predicted to become efficient and renewable sources for valuable products in the future due to their high biomass synthesis using CO2 and solar energy. Microalgae are producers of several carotenoids including lutein, which is a xanthophyll carotenoid with several health advantages, including the prevention of age-related macular degeneration. Currently, it is extracted on commercial scale from marigold flower petals, however, production from plant sources is highly affected by seasonal variations, requires arable land, and has high production cost. Microalgae, on the other hand, are an ideal alternative for lutein synthesis due to their rapid growth and high biomass and lutein yield. It is, however, necessary to further improve lutein productivity, for a successful transition to commercial production. This article describes lutein biosynthesis in microalgae by using their native biochemical pathways, as well as possible target genes for genetic engineering to enhance lutein production. Understanding the processes behind lipid droplet synthesis in chloroplasts, as well as carotenoid transport across chloroplast membranes and carotenoid esterification, might lead to novel ways to boost lutein levels in microalgae.
