The use of artificial ingredients to augment food production has led to the increasing incidence of various health hazards globally. Nowadays, factors such as rising health consciousness and the growing inclination toward environment-friendly products are driving the demand for naturally produced foods. Thus, due to the growing demand for natural products, manufacturers are widely using natural colors to retain the attractiveness of food products after processing.
Natural colors or dyes are mainly obtained from algae, plants, animals, fruits, and insects, making them safe for use as food additives as they are free from harmful side effects. The therapeutic uses of natural colors are also growing due to the non-toxic or less toxic nature and fewer side effects of natural products. Governments of various countries are increasingly supporting the use of natural food colors as they are biodegradable and do not cause pollution after disposal. Moreover, several regulations encouraging the use of natural colors instead of synthetic food colors have been passed in many regions, which is further expected to drive the demand for natural food colors across the globe. According to the consumer advocacy group—Centre for Science in the Public Interest (CSPI), artificial food coloring poses many health risks to consumers.
Moreover, increasing government initiatives for encouraging the adoption of natural food colors in various food & beverage applications, increasing consumer preference for organic and clean-label products, and the general “health and wellness” trend will continue to influence the demand for natural food colors across the globe. Beta-carotene, a Dunaliella salina extract, is widely used to impart a yellow to orange color to foods and cosmetic products. Moreover, beta-carotene extracted from Dunaliella salina is mainly used as a colorant in the manufacture of bakery products, beverages, functional drinks, coatings, compound seasonings, confectionery, flour products, frozen drinks, cheese, dairy products, margarine, jam, cooked meat products, egg products, jelly, and puffed food products. Nowadays, various factors such as the growing awareness regarding the benefits of natural food colors, increasing awareness for clean-label products, growing need to enhance product appeal, growing research & development activities in the food industry, and increasing use of microencapsulation technology are some of the key factors driving the growth of the natural food colors market across the globe. For instance, the natural food colors market is expected to reach $3.2 billion by 2027, at a CAGR of 8.4% from 2019 to 2027 (Source: Meticulous Research® Analysis).
Therefore, the growing demand for natural colorants drives the demand for beta-carotene, which is ultimately expected to drive the demand for Dunaliella salina biomass worldwide. Meticulous Research® in its latest publication on the ‘Dunaliella Salina Market,’ states that the Dunaliella Salina Market is expected to reach $122.9 million by 2028, at a CAGR of 4.0% during the forecast period 2021 to 2028. Also, in terms of volume, the Dunaliella salina market is expected to record a CAGR of 3.7% from 2021 to 2028 to reach 1,691.62 tons by 2028.
