Glucosinolates, carotenoids, and fat-soluble vitamins E and K contents were analyzed from various kale and collard cultivars at mature stage. We found a significant difference in these phytonutrients among cultivars. Among kale cultivars, “Beira” and “Olympic Red” were the highest in the total glucosinolate and “Toscano” kale was the highest in total carotenoid content. “Scarlet” kale was highest in tocopherols. For collard, total glucosinolate was the highest in “Top Bunch” while carotenoids were the highest in “Green Glaze.” An accession PI261597 was the highest in phylloquinone. In addition to the total content of each phytonutrient class, their composition differed among cultivars, indicating that each cultivar may have differential regulatory mechanisms for biosynthesis of these phytonutrients. Our result indicates that cultivar selection may play an important role in consumption of kale and collard with greater nutritional benefit. Therefore, the result of this study will provide a more thorough profile of essential and nonessential phytonutrients of kale and collard cultivars for consumers’ choice and for future research on nutritional value of these crops.

Carotenoids are bioactive substances in human diet. The aim of the study was to determine β-carotene and xanthophylls in four berries species. An HPLC gradient elution system were used for separation and quantification of the carotenoids. The highest total carotenoid content among the berries studied was found in cloudberry (2840 μg/100g dw), followed by blueberry (2140 μg/100 g). All berries had lutein but it was a predominant carotenoid in blueberry. The highest β-carotene levels were found in cloudberry (83% of total Car content). Cranberry and cowberry were the poorest sources of carotenoids. Our data will be included in the regional database of resources with the increased nutritional value.

Cassava is the food base for millions of people in tropical Africa, Latin America and Asia. However, cassava commercial varieties are deficient in vitamin A and the consumption of biofortified cassava, which has a higher concentration of Beta-carotene in the roots, represents an alternative to prevent this deficiency. Dehydrated products are an integral part of many consumers’ diet, which have preferred healthier and lower calorie foods. This study aimed to develop a dehydrated product of cassava (dehydrated chips) from biofortified varieties. The dehydrated chips were elaborated from the following biofortified cassava genotypes: BRS Dourada, BRS Gema de Ovo, BRS Jari and hybrid 2003 14-11. For obtaining the dehydrated chips, cassava roots were washed, sanitized, peeled, sliced to a thickness of 0.8 mm, blanched and dehydrated at 65 °C. First, dehydrated chips were prepared with no added flavoring, from roots of four cassava genotypes harvested at 12 months after planting, in order to select the two most suitable for dehydrated chips production based on sensory acceptance. In the second stage, dehydrated chips were produced with the addition of onion and parsley flavoring, from the two genotypes selected in the previous step. The BRS Jari variety and hybrid 2003 14-11 showed highest total carotenoid content, 10.54 ?g g g-1 and 6.92 ?g g g-1, respectively, and  Beta-carotene, 8.93 ?g g g-1 and 4.98 ?g g g-1, respectively. For carotenoids and Beta-carotene retention there was no significant difference among the dehydrated chips prepared with four biofortified cassava genotypes, which showed average values of 76% and 67%, respectively. Dehydrated chips made with the BRS Jari and hybrid 2003 14-11 had highest average for flavor attribute and did not differ on the crispness and overall acceptance and classified between "like slightly” and "like moderately”. Despite the addition of "onion and parsley" flavoring, there has been no greater acceptance by consumers. Dehydrated cassava chips made with the BRS Jari variety and the hybrid 2003 14-11 showed good sensorial acceptance and higher total carotenoid and Beta-carotene contents, thus being biofortified varieties suitable for the elaboration of this product.

Cucurbita moschata Duch. is a seasonal crop, appreciated for its nutrimental and bioactive components especially carotenoids. From the whole edible plant, fruit is most often consumed which can be stored and also processed. Six varieties—Liscia, Matilda, Orange, Serpentine, UG 205 F1, and Waltham—of Cucurbita moschata Duch. were investigated, in order to analyze and evaluate the changes in total carotenoids content in the pulp during storage and after the effect of heat treatments—freezing, baking, and cooking (water boiling). The average total carotenoids content ranged from 3.32 mg/100 g (Serpentine) to 9.35 mg/100 g fresh matter (FM) (Orange). After 60 days of storage, a slight increase in the total carotenoids content of all analyzed varieties was observed. The values of the monitored varieties ranged from 4.18 mg/100 g FM (Serpentine), which represents a 26% increase to 10.96 mg/100 g FM (Orange), where a 17% increase was observed. After 120 days of storage, the results were mixed. In some varieties (Liscia and Matilda), the total carotenoid content decreased, while in the varieties Serpentine, UG 205 F1, and Waltham, its content increased slightly (11%, 3%, and 11%), but the content of the Orange variety remained unchanged. The total carotenoids increment after 60 and 120 days of storage in the dry matter (DM) was statistically significant, as well as the effect of the variety. The total carotenoid content of cooked samples of all varieties increased, from 119.78 mg/100 g DM (Waltham) to 255.19 mg/100 g DM (Orange). After baking, an average of 12% increase in the total content of carotenoids was recorded, after freezing, a decrease in its level of 5% was indicated. The findings of this work show that Cucurbita moschata Duch. is a good source of carotenoids, even after several weeks of storage and after exposure to heat treatments.

Biofortified yellow-fleshed cassava is important in countries with high cassava consumption, to improve the vitamin A status of their populations. Yellow- and white-fleshed cassava were evaluated over three locations for proximate composition and cyanide content as well as retention of carotenoids after boiling. There was significant variation in the crude fiber, fat, protein and ash content of the genotypes. All but one of the yellow-fleshed cassava genotypes recorded higher protein values than the white-fleshed local genotypes across locations. The cyanide content of the genotypes varied between locations but was within the range of sweet cassava genotypes, but above the maximum acceptable recommended limit. Micronutrient retention is important in biofortified crops because a loss of micronutrients during processing and cooking reduces the nutritional value of biofortified foods. Total carotenoid content (TCC) ranged from 1.18–18.81 μg.g−1 and 1.01–13.36 μg.g−1 (fresh weight basis) for fresh and boiled cassava, respectively. All the yellow-fleshed cassava genotypes recorded higher TCC values in both the fresh and boiled state than the white-fleshed genotypes used as checks.

The aim of this study was to evaluate the effect of a supplementation diet for hens consisting of dried basil herb and flowers of calendula and dandelion for color, carotenoid content, iron-induced oxidative stability, and sensory properties of egg yolk compared with commercial pigment (control) and marigold flower. The plant parts were supplemented in diets at two levels: 1% and 3%. In response to dietary content, yolks from all diets differed in carotenoid profile (p < 0.001). The 3% supplementation level resulted in a similar total carotenoid content as the control (21.25 vs. 21.79 μg/g), but by 3-fold lower compared to the 3% marigold (66.95 μg/g). The tested plants did not achieve yolk color fan values as the control (13.47) or 3% marigold (11.47), and among them, calendula had the highest values (9.73). Despite the low carotenoid content in diets supplemented with basil herb, iron-induced malondialdehyde (MDA) concentration was low as for marigold (on average 106.83 vs. 92.68 ng/g after 250 min). The treatments differed in sensory color scores for fresh and hard-boiled yolks and flavor while other sensory properties were similar. In conclusion, the supplementation of plants in a hen diet may result in yolks containing carotenoids and other compounds showing a high antioxidant effect.

Proper diet is critical for laboratory-reared animals, as it may affect not only their welfare, but also experimental results. Amphipods (Crustacea: Amphipoda) play important roles in ecosystems and are often used in environmental research. Endemic amphipods from the ancient Lake Baikal are promising for laboratory bioassays; however, there are currently no laboratory cultures. In this work, we determine how different diets affect the color and metabolism of a laboratory-reared Baikal amphipod, Eulimnogammarus cyaneus. We found that in freshly collected blue-colored animals, body color correlated with total carotenoid content. Total carotenoid levels did not differ after long-term (two months) feeding with a close to natural carotenoid-enriched, or even a carotenoid-depleted diet. Nevertheless, antennae color was closer to red in the natural-like diet group. It is likely that the carotenoids from the commercial diet are not properly metabolized in E. cyaneus. The animals fed commercial diets had a higher glycogen content, which may signify a higher metabolic rate. Overall, we show that a carotenoid-enriched diet optimized for decapods is not optimal for amphipods, likely due to different carotenoid compositions, and the diet for long-term rearing of E. cyaneus and other Baikal amphipods requires supplementation.

Background. Barbary fig (Opuntia spp), called prickly pear, is a cultivated species belonging to family Cactaceae. It produces fruits one time per year during a short season. It is largely spreading in the Mediterranean countries. The aim of the study was to investigate the physicochemical and biochemical analysis of powder of prickly pear fruit peels of three Moroccan varieties (Aakria, Derbana, and Mles). Material and Methods. Both physicochemical analysis (humidity, water activity, Brix, ash content, pH, and total titratable acidity) and biochemical analysis (total carotenoid content, betalain content, total polyphenolic content, and ascorbic acid content) were effectuated according to protocols reported within the present research work. Results. Regarding the physiochemical analysis, the humidity of powder of prickly pear fruit peels ranged from 10.173 ± 0.002 to 15.27 ± 0.02%. The water activity (aw) ranged from 0.17 ± 0.002 to 0.336 ± 0.002. The values of Brix ranged from 68.67 ± 0.33 to 74.22 ± 0.51° Bx. pH values ranged from 5.41 ± 0.01 to 5.62 ± 0.01. The total titratable acidity values ranged from 0.644 ± 0.014 to 0.76 ± 0.007 g citric acid/100 g DM (dry matter). The ash content ranged from 1.02 ± 0.02 to 11.41 ± 0.03 g/100 g DM. Regarding the biochemical analysis, the total carotenoid content ranged from 5.14 ± 0.10 to 9.79 ± 0.06 mg/g of FM (Fresh matter). The total betalain content ranged from 2 ± 0.69 to 37.66 ± 2.65 mg/100 g of DM. The total polyphenolic content ranged from 1739.92 ± 13.69 to 2409.66 ± 43.65 mg gallic acid equivalent (GAE)/100 g of DM. The ascorbic content values ranged from 186.78 ± 13.23 to 294.04 ± 5.81 mg/100 g of DM. Conclusion. The results showed an interesting richness of the investigated powder in pigments (betacyanins, indicaxanthins, and carotenoids) and nutritional compounds including sugar, proteins, and vitamins that make this powder interesting for being used as a dye in food.
