Velitchkova M, Stefanov M, Popova AV. Effect of Low Light on Photosynthetic Performance of Tomato Plants-Ailsa Craig and Carotenoid Mutant Tangerine. PLANTS (BASEL, SWITZERLAND) 2023; 12:3000. [PMID: 37631211 PMCID: PMC10459318 DOI: 10.3390/plants12163000] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/20/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023]
Abstract
The effects of a five-day treatment with low light intensity on tomato plants-Ailsa Craig and tangerine mutant-at normal and low temperatures and after recovery for three days under control conditions were investigated. The tangerine tomato, which has orange fruits, yellowish young leaves, and pale blossoms, accumulates prolycopene rather than all-trans lycopene. We investigated the impact of low light at normal and low temperatures on the functioning and effectiveness of photosynthetic apparatuses of both plants. The photochemical activities of Photosystem I (PSI) and Photosystem II (PSII) were assessed, and the alterations in PSII antenna size were characterized by evaluating the abundance of PSII-associated proteins Lhcb1, Lhcb2, CP43, and CP47. Alterations in energy distribution and interaction of both photosystems were analyzed using 77K fluorescence. In Aisla Craig plants, an increase in thylakoid membrane fluidity was detected during treatment with low light at a low temperature, while for the tangerine mutant, no significant change was observed. The PSII activity of thylakoids from mutant tangerine was more strongly inhibited by treatment with low light at a low temperature while low light barely affected PSII in Aisla Craig. The obtained data indicated that the observed differences in the responses of photosynthetic apparatuses of Ailsa Craig and tangerine when exposed to low light intensity and suboptimal temperature were mainly related to the differences in sensitivity and antenna complexes of PSII.

Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on yellow/orange tomato extract used as a novel food (NF) pursuant to Regulation (EU) 2283/2015. The NF which is the subject of the application is a carotenoid-rich extract from the yellow/orange tomato containing predominantly phytoene and phytofluene, as well as a lesser amount of beta-carotene, zeta-carotene and lycopene. The NF is produced from the tomato pulp using supercritical CO2 extraction. The applicant proposes the use of the NF in cereal bars, functional drinks and as a food supplement in individuals above 15 years of age. For the use of the NF in cereal bars and functional drinks, the Panel considers, the target population is the general population. According to EFSA's latest exposure assessment for lycopene as a food additive (EFSA ANS Panel, 2017), the highest P95 intakes for children (< 10 and 10-17 years) and adults when combined to the use of lycopene as a food colour from natural occurrence would exceed the established acceptable daily intake (ADI) for lycopene (0.5 mg/kg body weight (bw) day). The estimated intakes of the NF would lead to an exceedance of the ADI when considering natural occurrence and exposure to lycopene when used as a food additive. Due to the absence of safety data regarding phytoene and phytofluene intake from the NF, and the contribution of the NF to the estimated high daily intakes of lycopene, the Panel considers that it cannot be established whether or not the consumption of the NF is nutritionally disadvantageous. The Panel concludes that the safety of the NF has not been established under the proposed conditions of use.

Carotenoid composition and antioxidant activities of Chinese orange-colored tomato cultivars and the effects of thermal processing on the bioactive components. J Food Sci 2021; 86:1751-1765. [PMID: 33856048 DOI: 10.1111/1750-3841.15682] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Revised: 02/09/2021] [Accepted: 02/12/2021] [Indexed: 11/28/2022]
Abstract
To facilitate the production of tomato products with high bioactivity and improve the utilization of orange-colored tomatoes, the carotenoids of 11 tomato cultivars were analyzed using high-performance liquid chromatography with photodiode array detection. Moreover, antioxidant activities were evaluated by four chemical-based assays, and the influences of thermal treatment on the carotenoids in orange-colored tomatoes rich in tetra-cis (7Z, 9Z, 7'Z, and 9'Z)-lycopene, phytofluene, and phytoene were studied. The nine orange-colored tomatoes (OT) were divided into two categories: OT-B, containing five cultivars rich in β-carotene, and OT-L, containing the other four cultivars that were abundant in tetra-cis-lycopene, phytofluene, and phytoene. The antioxidant activities of OT-L were higher than those of OT-B and the SD-2 cultivar in OT-L showed similar antioxidant activity to the red tomatoes. During thermal processing, tetra-cis-lycopene in SD-2 decreased about 38% after being exposed to heat for 2 hr at 80 °C, while its content was still higher than other lycopene isomers. Other-Z-lycopenes and all-trans (E)-lycopene increased from 2.36 ± 0.19 to 14.73 ± 1.16 µg/g fresh weight (FW) and 0.75 ± 0.10 to 5.91 ± 1.02 µg/g FW, respectively. Thus, thermal treatments at lower temperature, such as cold break and pasteurization, were more suitable for processing OT-L. The results demonstrated that OT-L could be an excellent raw material to produce tomato products with high bioavailability and bioactivity. The results of this research could provide helpful information for the research and development of tomato products using orange tomatoes and benefit planters and consumers. PRACTICAL APPLICATION: Some orange tomato cultivars are promising raw materials for tomato products because of their high contents of bioactive tetra-cis-lycopene, phytofluene, and phytoene. This study demonstrated the carotenoid components and antioxidant activities of the widely planted orange-colored tomatoes in China. The obtained knowledge, including the thermal processing effects on the isomerization and degradation of carotenoids in the cultivars, will offer useful information to food processors and benefit the consumers.

Antioxidants (Basel) 2020; 9:E916. [PMID: 32993035 PMCID: PMC7600476 DOI: 10.3390/antiox9100916] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 09/21/2020] [Accepted: 09/24/2020] [Indexed: 12/24/2022] Open
Abstract
Human skin is continuously subjected to environmental stresses, as well as extrinsic and intrinsic noxious agents. Although skin adopts various molecular mechanisms to maintain homeostasis, excessive and repeated stresses can overwhelm these systems, leading to serious cutaneous damage, including both melanoma and non-melanoma skin cancers. Phytochemicals present in the diet possess the desirable effects of protecting the skin from damaging free radicals as well as other benefits. Dietary phytochemicals appear to be effective in preventing skin cancer and are inexpensive, widely available, and well tolerated. Multiple in vitro and in vivo studies have demonstrated the significant anti-inflammatory, antioxidant, and anti-angiogenic characteristics of dietary phytochemicals against skin malignancy. Moreover, dietary phytochemicals affect multiple important cellular processes including cell cycle, angiogenesis, and metastasis to control skin cancer progression. Herein, we discuss the advantages of key dietary phytochemicals in whole fruits and vegetables, their bioavailability, and underlying molecular mechanisms for preventing skin cancer. Current challenges and future prospects for research are also reviewed. To date, most of the chemoprevention investigations have been conducted preclinically, and additional clinical trials are required to conform and validate the preclinical results in humans.
