Total carotenoid content, α-carotene and β-carotene, of landrace pumpkins (Cucurbita moschata Duch): A preliminary study

Effects of selected agronomical factors on the content of health-promoting compounds in spaghetti squash (Cucurbita pepoL. subsp.pepo)The study examined the effects of the sowing date (5, 15 and 25 May) and plant spacing (1 × 0.6 m, 1 × 0.8 m and 1 × 1 m) on the content of carotenoids and L-ascorbic acid in the fruits of two cultivars of spaghetti squash (‘Makaronowa Warszawska' and ‘Pyza’). The field experiment was carried out in central-eastern Poland. Fully mature spaghetti squash fruits were harvested from the beginning of September to the beginning of October. The content of total carotenoids and β-carotene was the greatest in the fruits of plants sown on 15 May. The sowing date did not affect the content of L-ascorbic acid. Increasing the plant spacing from 1 × 0.6 m to 1 × 1 m resulted in an increase of total carotenoid content, particularly for the spaghetti squash sown on 25 May. Plant spacing did not have a significant effect on the content of β-carotene and L-ascorbic acid. Fruits of the ‘Makaronowa Warszawska’ with light orange flesh contained more total carotenoids and β-carotene than fruits of the ‘Pyza’ with cream-coloured flesh. The content of L-ascorbic acid in the fruits of both cultivars did not differ significantly.

The winter squash is an important source of antioxidants, especially carotenoids. The aim of submitted research work was to determine the effect of genotype, storage and different methods of technological processing (baking, boiling and sterilization) on the content of ascorbic acid and total carotenoids in fruits of winter squash (Cucurbita moschata Duch. ex Poir.). The small-plot field experiment was established at Slovak University of Agriculture in Nitra in 2013. Five cultivars of winter squash (‘Liscia’, ‘Orange’, ‘Hannah’, ‘UG 205 F1’ and ‘Waltham’) were examined in experiment. The total carotenoids content in the pulp of fresh fruits was ranged from 9.33 to 15.10 mg.100 g−1. Its highest value was determined in case of ‘Orange’ variety. The storage and the thermal treatment of fruit pulp in case of baking had positive impact from the total carotenoid content point of view. The baking resulted in the increase of its value in winter squash. On the contrary, sterilization tended to the decrease of total carotenoid content in edible part of squash. The total carotenoids content in the baking pulp was ranged from 14.27 to 31.87 mg.100 g−1. The vitamin C content before storage and technological processing ranged in interval from 13.88 to 18.69 mg.100 g−1. Particular thermal methods of processing and storage resulted in decrease of vitamin C content in the pulp of all winter squash varieties.

ABSTRACTWinter squash fruits (Cucurbita moschata D.) are among the best sources of vitamin A precursors and constitute sources of bioactive components such as phenolic compounds and flavonoids. Approximately 70% of C. moschata seed oil is made up of unsaturated fatty acids, with high levels of monounsaturated fatty acids and components such as vitamin E and carotenoids, which represent a promising nutritional aspect in the production of this vegetable. C. moschata germplasm expresses high genetic variability, especially in Brazil. We assessed 91 C. moschata accessions, from different regions of Brazil, and maintained at the UFV Vegetable Germplasm Bank, to identify early-flowering accessions with high levels of carotenoids in the fruit pulp and high yields of seed and seed oil. Results showed that the accessions have high variability in the number and mass of seeds per fruit, number of accumulated degree-days for flowering, total carotenoid content, and fruit productivity, which allowed selection for considerable gains in these characteristics. Analysis of the correlation between these characteristics provided information that will assist in selection to improve this crop. Cluster analysis resulted in the formation of 16 groups, confirming the variability of the accessions. Per se analysis identified accessions BGH-6749, BGH-5639, and BGH-219 as those with the earliest flowering. Accessions BGH-5455A and BGH-5598A had the highest carotenoid content, with averages greater than 170.00 μg g-1 of fresh mass. With a productivity of 0.13 t ha-1, accessions BGH-5485A, BGH-4610A, and BGH-5472A were the most promising for seed oil production. These last two accessions corresponded to those with higher seed productivity, averaging 0.58 and 0.54 t ha-1, respectively. This study confirms the high potential of this germplasm for use in breeding for promotion of earlier flowering and increase in total carotenoid content of the fruit pulp and in seed and seed oil productivity.

The information on the responses to simple recurrent selection for yield and total carotenoid content in orange waxy corn is lacking. The objectives were to evaluate the responses to simple recurrent selection for two cycles for yield and carotenoids of orange waxy corn population and to investigate the correlations between color parameter with carotenoids in waxy corn kernels. Parental sources of germplasm with differences in kernel colors and levels of disease resistance were used for generation of a base population of orange waxy corn. A simple recurrent selection for superior phenotypes was practiced on this population for two selection cycles. Cycle 0 (C0), C1 and C2 were evaluated for two locations in 2016. The cycles showed significant differences for most traits except for plant height. The locations contributed to large portions of total variation in total yield, whereas selection cycle contributed to large portions of total variations in lutein, zeaxanthin, β-carotene and total carotenoid content and color parameter (ho), indicating that selection for carotenoids would be possible. Simple recurrent selection for two cycles increased total yield and husked ear weight of 23.2% and 15.0%, respectively. Simple recurrent selection for two cycles also increased lutein, zeaxanthin, β-carotene and total carotenoid content with increasing percentages ranging from 18.5 to 196.6%. The results indicated that population improvement by simple recurrent selection could be useful in increasing these traits. Color parameter at immature stage and dry stage was negatively and significantly correlated with lutein, zeaxanthin, β-carotene and total carotenoid content, indicating that color parameter can be used as an indirect selection criterion for these traits.

Carotene Synthesis

In the current research, the potential of Spanish-style green olive processing wastewaters (lye and washing waters) exploitation toward natural β-carotene production by Blakeslea trispora was tested for the first time. Mating culture generated by the joint cultivation of the heterothallic fungal strains ATCC 14271 and 14272 in the non-sterile lye and washing waters was able to grow, achieving the phytotoxic hydroxytyrosol degradation by 57.3% and 66.8%, respectively. However, the low sugar and nitrogen content of the streams did not favor carotenogenesis. Alternatively, in the nutrient-enriched effluents, a notable quantity of β-carotene was produced, accounted for 61.2 mg/L (lye) and 64.1 mg/L (washing waters) (82–88% of total carotenoid content). Above all, enriched streams had a noteworthy stimulating effect on the β-carotene synthesis, because both the maximum β-carotene yield per volume of enriched effluents and specific β-carotene production rate were higher when compared with the respective values obtained from trials with synthetic reference medium without added effluents. Hydroxytyrosol and tyrosol showed high stability during the non-sterile process for β-carotene production by B. trispora grown in the enriched effluents. This finding strengthens the potential toward the generation of multiple high-value products, which could lower the natural β-carotene production costs.

Β Carotene

The effect of the industrial processing of peppers for paprika on carotenoids with provitamin A activity has been investigated. The processing consists of two principal steps: drying and milling. The milling step appears to be the more destructive, leading to a loss of 42.7 to 55.2% in the total carotenoid content and 65.2 to 81.4% in that of provitamin A, depending on the variety of the fruit. However, adding seeds from the peppers during this step dilutes the paprika, reducing the carotenoid losses due to the process itself to around 20%. The drying step is less destructive, but its final effect depends markedly on the degree of ripeness of the fruit and the variety of peppers used. Carotenoids with provitamin A value present in Capsicum annuum are β-carotene, β-cryptoxanthin, and cryptocapsin, which are degraded during the process by 67.3 to 82.2%, 59.2 to 78.9%, and 54.1 to 58.1 % respectively, resulting in a loss of provitamin A activity of ca. 65.2 to 81.4%.
