The tomato is a Solanaceae plant which globally has the second highest production rate, making it one of the most important vegetative products in global production and consumption. Furthermore, the tomato is valued for its antioxidant components, most notably vitamin C, phenolic components and carotenoids such as lycopene and β-carotene. The present study aimed to evaluate the influence of three drying temperatures (50, 60 and 70°C) on the physicochemical, microstructural, and antioxidant characteristics of the tomato. The study analyzed the parameters for color using the coordinates CIE L* a* b* and texture analysis using the methodology of TPA for instrumental analysis and PCA for data analysis, antioxidant capacity and content were measured by spectrophotometric methods and microestructure by Scanning Electron Microscope. The results showed changes in color for the tomato samples treated with 70°C. In addition, the texture of the samples treated at 60°C presented significant differences from the samples dried at 50 and 70°C regarding the fracturability, having a crispier texture and good balance between masticability and hardness. The total carotenoid content increased with the drying process, while the total phenol content decreased. The antioxidant activity was not affected by the temperature variation with respect to the fresh tomato.

Apricots are well known for the high content of bioactive compounds such as carotenoids, polyphenols, vitamins and minerals. Several studies have pointed out the chemical composition or the biological effects of apricots, but limited information are available regarding the stability of active compounds during storage or processing. The aim of this study was to determine the stability of major carotenoids in commercial dried apricots during storage.Carotenoids were extracted monthly from dried apricots kept in a dark environment, at room temperature, for twelve months. Total carotenoids were determined using the spectrophotometric method while the most relevant carotenoids were analyzed by high-performance liquid chromatography-photodiode array detection (HPLC-PDA) on a C30 column and using a gradient elution system.Initial carotenoid content of dried fruits was 6.72 mg/100g, while after six months of storage it decreased to 2.46 mg/100g. After twelve months of storage the total carotenoid content was 0.82 mg/100g, representing 20.35 % of the initial concentration. The major carotenoids identified in apricots were: all trans β-carotene, its geometrical isomers (9-cis-β-carotene; 13-cis-β-carotene; 9,13-di-cis β-carotene); β-carotene-5,8-epoxide; β-cryptoxanthin and β-cryptoxanthin palmitate. Significant decreases were observed for all pigments but all trans β-carotene appears to be the most sensitive pigment, with 15.7 % residual concentration. Although the concentrations of β-cryptoxanthin palmitate is small, it has shown significant increased stability compared to carotenes.

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.

AbstractThe worldwide consumption of blueberries has increased due to their potential health effects. They contain micronutrients, various phytochemicals and anti-oxidant pigments, represented especially by anthocyanins. In addition to these, carotenoids and fatty acids are also present. The aim of this study was the identification and quantification of carotenoids (by HPLC) and fatty acids (by GC with flame ionisation detection) in two bilberry genotypes (Wild 1 and 2) and three cultivars (BlueCrop, Elliot, and Duke). The main carotenoids identified were lutein, β-cryptoxanthin, and β-carotene, with the average total carotenoid content of 266 μg per 100 g of fruit. The ratio of saturated fatty acids (SFAs) to polyunsaturated fatty acids (PUFAs) was 0.098 for Wild 1 and 0.11 for Wild 2 genotypes and ranged from 0.14 to 0.28 for cultivars. The main fatty acids identified were linoleic (18:2) and linolenic (18:3) acids in all the samples analysed. In Vaccinium myrtillus the amount of carotenoids and fatty acids was higher than in Vaccinium corymbosum species.

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.

AbstractTo better understand the fruit flesh coloration mechanism of peach (Prunus persica), the composition and accumulation of carotenoids were compared, the expression profile of key genes involved in carotenoid biosynthetic and catabolic pathways was performed, and the differentially expressed genes were identified using “Piqiutao” (white fruit flesh) and its mutant yellow “Piqiutao” at different fruit development stages. The results showed that the total carotenoid content in yellow “Piqiutao” was remarkably higher than that of “Piqiutao,” and the accumulation of β-cryptoxanthin, α-carotene, and β-carotene was significantly different, which was most likely caused by the differential expression of CCD4. Therefore, CCD4 may be an essential gene that causes the yellow fruit flesh of yellow “Piqiutao.” However, the coding region sequence of CCD4 was entirely identical, and the intron was inserted by a retrotransposon in “Piqiutao” and its mutant, indicating that the expression difference was not caused by the sequence mutation and retrotransposon insertion.

Cherry Tomatoes

Cherry tomatoes are rich sources of carotenoids. The carotenoids are known to be precursors of vitamin A and also act as an antioxidant. It is important to visually judge the tomato surface color for higher β carotene content since this is the major provitamin AA carotenoid. Estimation of carotenoids by HPLC (High Performance Liquid Chromatography) and spectrophotometric methods in tomatoes are very expensive and time consuming. Therefore, colorimeters can be used to describe the color and determine the carotenoid content in a relatively easy and inexpensive manner. The objective of this study was to determine, if the carotenoid content within cherry tomatoes measured by conventional method could correlate with colorimetric CIE (Commission International del’Eclairage) L*, a*, b* color space values. Strong correlations were found between color surface value a* and total carotenoids (0.82) and lycopene content (0.87). We also observed positive correlation for the b* color value with β carotene (0.86). The L* value was negatively correlated (-0.78) with an increase in carotenoids. These close associations between color space values L*, a*, b* and carotenoids will help the breeders to quickly screen large germplasm/ breeding lines in their breeding program for improvement in carotenoid content through this time saving, inexpensive and nondestructive method at fully ripe stage.

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.

This study was carried out to evaluate the antilisterial activity of carrot, and the impact of its incorporation on the carotenoid content in Minas Frescal cheese, combined or not with high hydrostatic pressure processing, as an alternative for the development of healthier fresh cheese free of synthetic preservatives. Cheeses were manufactured with milk added with carrot incorporation (0, 3, and 6%) and pressurized (0; 250 and 500 MPa/10 min). Total carotenoid content, α-carotene, β-carotene, lutein, consumer acceptance, and sensory characteristics were determined one day after the manufacture while Listeria innocua enumeration was evaluated up to 22 days of storage at 8 ℃. The results showed that although a decrease of over 7 log CFU g−1in L. innocua counts was observed immediately after fresh cheese processing at 500 MPa/10 min, inactivation was not complete, as the growth of this nonpathogen surrogate during storage was observed. The addition of 6% carrot had a slight bacteriostatic effect, verified on the 15th day of storage, particularly in pressurized cheeses. On the other hand, high pressure treatment at 500 MPa/10 min increased carotenoids degradation in cheeses. Although pressurized cheeses were characterized as “rubbery,” high hydrostatic pressure had no significant effect on consumer acceptance.
