“…The quantity of total carotenoids in achiote seeds was reported about 4.5%–5.5% of seed weight (Giridhar et al . ). There are two main types of apo‐carotenoid pigments namely bixin (C 25 H 30 O 4 ; oil soluble) and norbixin (C 24 H 28 O 4 ; alkaline water soluble).…”

Discovering natural carotenoids for colour enhancement and health benefits of fish is important to develop new feed formulations. We have purified natural bixin from achiote seeds and evaluated the effect of colour enhancing and pigmentation in goldfish. Varying levels of bixin-based diets were prepared with 420 g kg À1 of crude protein and 120 g kg À1 of lipid content. Our results clearly showed that bixin (0.05, 0.10, 0.20 and 0.60 g kg À1 ) based diets significantly (P < 0.05) enhanced the skin and fin colour at 30 and 60 days compared to diet without bixin. Interestingly, diet which contains 0.20 g kg À1 bixin and commercial feed (with astaxanthin) had similar effect on carotenoid deposition in skin. Moreover, total carotenoid deposition in fin was higher than in skin of all bixin-containing diets. However, 0.60 g kg À1 bixin-containing diet had lower specific growth rate (1.01 AE 0.01) and higher feed conversion ratio (2.05 AE 0.19) compared to the control group. The present results demonstrate that achiote bixin can be successfully used as an alternative natural carotenoid source against synthetic astaxanthin in fish feed. Our data indicate that 0.20 g kg À1 is a suitable dietary level of bixin to ensure strong pigmentation, acceptable growth and feed utilization in goldfish.

“…Though in that study, they have not analyzed the bixin content in the seeds, but they have studied the bixin content in oil which is used for pigment extraction from the seeds of different location. The quality of seeds and their geographical condition has influence on annatto dye yield as evident from various reports wherein, the seeds from Peru are the best with 3-4% bixin content (Giridhar et al, 2014). In the first method, the water soaking of seeds had significant effect on bixin content of the extracts (Table 1).…”

Annatto, a naturally obtained colour is a potential and valuable Non Wood Forest Product (NWFP). It is obtained from the seeds of plant species Bixa orellana L. The present experiment was carried out to find the efficacy of different oils used for annatto colour extraction. Experiment was started with the pretreatment of seeds of B. orellana with soaking in water at 0%, 50%, 100% and 150% (v/w) for 24 hrs at room temperature and colour extraction with castor oil at 100°C showed that maximum bixin (%) was found from the pretreated seeds with 50% (v/w) water soaking i.e., 0.46% bixin. Similarly for oil soluble annatto extraction method, the maximum extraction of bixin (0.99 %) was found with castor oil at 120°C for 1 hr and least bixin (0.03 %) was recorded with mustard oil at 60 o C temperature for 1 hr. Sesame oil and ground nut oil were also showed better extractability. Out of different treatments, castor oil at 120°C for 1 hr gave better result with respect to bixin extraction as compared to others.

Many dyes are contained in plants and are used for coloring a medium. They are characterized by their content of dyes molecules. They stimulate interest because they are part of a sustainable development approach. There are several chemicals families of plant dye which are contained in more than 450 plants known around the world. In this article, a study based on literature allowed us to realize an inventory of the main dyes plants potentially present in Morocco. A list of 117 plants was established specifying their botanical families, chemical Composition, Colors and parts of the plant used.
