“…Annatto extract is commonly used in various food products such as beverages, butter, cheese, cereals, margarine, and snack foods as a coloring dye 19,20 . The annatto seed contains 4.5% to 5.5% of total carotenoids which shows antimicrobial and antioxidant properties 21 …”

Natural colorimetric indicators have been fabricated using annatto and pomegranate extract powder and compared with chemical colorimetric indicator fabricated using bromophenol blue (BPB) to monitor the freshness of ready‐to‐cook (RTC) idli batter. The fabricated colorimetric indicator labels work on increasing headspace carbon dioxide (CO2) concentration and decreasing pH of stored batter, where indicators showed visible color change from lightest to darkest for spoiled samples. The headspace CO2 concentration of RTC idli batter increased from 0.15 ± 0.05 to 18.07 ± 0.21% (v/v) and pH decreased from 6.7 ± 0.06 to 4.5 ± 0.06 at optimum storage condition (35 ± 1°C) up to 24 h. The percent titratable acidity (% TA) increased from 0.44 ± 0.02 to 0.90 ± 0.02% up to 24 h. The viable lactic acid bacteria count (LABC) and total bacterial count (TBC) increased while yeast and mold count (YMC) was decreased with increasing fermentation time up to 24 h for batter stored at optimum condition. The color change of indicators was quantitatively measured with captured red, green, and blue (RGB) images. Pixel intensity for natural and chemical colorimetric indicators were decreased with increasing fermentation time. The leaching of chemical dye was observed on stored batter, and natural colorimetric indicators are nontoxic and successfully used as “on package sticker” for monitoring freshness of RTC idli batter.

“…The highest amount of carotenoids had been found in potato feed (Nhan, Minh, Liew, Hien, & Jha, 2019). In a 60‐day trial with Goldfish ( Carassius auratus ), 0, 50, 100, 200 and 250 mg/kg ratio annatto dye (AD) were added in their feed and the highest total carotenoid ratio was achieved with 200–250 mg AD kg −1 (Dananjaya et al., 2020).…”

“…As a result of the experiment, it was determined that the colour increase in the skin of the fish was quite high compared with the control group (Monica, Neelakantan, & Seenappa, 2019). The feeds of goldfish ( Carassius auratus ) were added 0, 50, 100, 200 and 250 mg/kg rates annatto dye (AD), and at the end of 60 days, the highest a * and b * values were obtained with 200–250 mg AD kg −1 feed (Dananjaya et al., 2020). Nettle ( Urtica spp.…”

“…It was seen that the pigment source added the feed had a positive effect (Zutshi & Madiyappa, 2020). In the results of 60‐day feeding with annatto dye (AD) at a rate of 0, 50, 100, 200 and 250 mg/kg added to goldfish ( Carassius auratus ) feeds, the highest survival rate was achieved with 100–200–200–250 mg AD kg −1 feed (Dananjaya et al., 2020). Orange sword tail fish ( Xiphophorus helleri ) fed with containing 400 mg/kg anthocyanin powder (extracted from beetroot peel and red cabbage), there was no difference in terms of growth and FCR compared with control feed (Monica et al., 2019).…”

“…There are four main pigment groups that give colour to the skin and tissues of animals and plants: melanins, purines, pteridiums and carotenoids (Jorjani, Sharifrohani, Mirhashemi Rostami, Hwai, & A., 2019;Kop & Durmaz, 2008). Carotenoids, which belong to oil-soluble pigment family, have a variety of sources such as natural (fungi, yeast and algae), animal (crustacean) and synthetic (lycopene, cantaxanthin, zeaxanthin, astaxanthin and β-carotene) (Cheng, Guo, Ye, & Wang, 2018;Dananjaya et al, 2020;Jiang et al, 2019;Sallam, Mansour, Srour, & Goda, 2017;Sanchez, Fuenmayor, Mejía, Díaz-Moreno, & Mahecha, 2020). Fish found in nature maintain their colours by feeding with a variety of copepods and plankton (Guerin, Huntley, & Olaizola, 2003;Xie et al, 2020;Yasir & Qin, 2010).…”

This study was done to assess the effect of the colouration of the red zebra cichlid (Maylandia estherae), using beet root red (Beta vulgaris ruba) and henna (Lawsonia inermis). The fish with an average weight of 1.21 ± 0.69 g was placed in 12 aquariums. Fifteen fish were placed in each aquarium. The fish were fed with diets which were without carotenoid supplement (AK), containing astaxanthin (AA), beet root red (AP) and henna (AI). Except the AK, each group contained 50 mg/kg carotenoid additives. As a result of the experiment, total carotenoid values between groups were not significant (p > .05). The redness (a*) value of groups was significant (p < .05), and the values of brightness (L*) and yellowness (b*) were not significant (p > .05). Samples were kept in the freezer at −20°C for 120 days to see whether the fish kept their colour. All groups decreased compared with the 50th day. This difference in groups except the AP was significant (p < .05). The FCR, SGR and weight gain% was not significant (p > .05). The survival was 97.28%, and it was the same in all groups. The study concluded that natural carotene sources with lower costs had similar effects with astaxanthin.
