Effects of nitric oxide on postharvest storage quality of Lycium barbarum fruit

Abstract

The L. barbarum fruit "Ke qi 608" was procured from the Institute of Chinese goji, Ningxia Yinchuan Academy of Agriculture and Forestry. For this, disease-free fresh fruit of Chinese goji were selected for processing. Sodium nitroprusside (SNP) reagent was provided by Shanghai Guangnuo Chemical Technology Co. (Shanghai, China) Treatment of goji berriesAbout 2700 freshly ripened goji fruits with uniform size were selected. Three parallel groups of 50 fruits in each group were divided, with no SNP as control (CK). Soak them in 75% alcohol for 2 min to disinfect and air dry naturally. Subsequently, 200 mL SNP solutions of different concentrations (0.0, 0.2, 0.4, 0.6, 0.8,

Transcriptome analysis reveals the gene expression changes in postharvest goji berry (Lycium barbarum L.) in response to hydrogen sulfide treatment

“…H 2 S treatment delayed the pectin degradation of Chilean strawberry during storage, significantly reduced the expression of pectin dissolving enzymes such as FcPG1 and FcPL1 genes, and reduced the expression of FcXTH1 (xylan endoglycosidase/hydrolase 1) genes (Molinett et al, 2021). The cotreatment of H 2 S and NO maintains high CHI (chitinase) and GNS (β-1,3-glucanase) and reduce PME, PG and EGase (endonuclease-β-1,4-glucanase) activity, reducing the decay rate of berry (Elam et al, 2022). H 2 S treatment of sweet cherry can reduce PG, PL β-GUL and β-The activity of GAL controls the development of surface pitting by stabilizing cell wall structure and regulating cell wall catabolism (Zhi et al, 2018).…”

“…The effects of goji berry include promoting blood production, anti-aging, anti-cancer, regulating blood sugar and blood lipids, and protecting the liver, kidneys and eyesight (Jiang et al, 2021;Ma et al, 2022a;Yang et al, 2022). Goji berry is mainly produced in the northwest of China (Fan et al, 2023), due to the high temperature in summer, fresh goji fruit thin skin and juicy is not easy to store and limit the promotion of fresh goji fruit consumption (Elam et al, 2022;Xing et al, 2022).…”

Carbon Dot-Mediated Photodynamic Treatment Improves the Quality Attributes of Post-Harvest Goji Berries (Lycium barbarum L.) via Regulating the Antioxidant System

“…Using a previous method described by Elam et al [ 4 ], the firmness of the fresh goji berries was measured using texture analyzer (TMS-PRO physical analyzer, FTC Company, Boston, MA, USA) using the following parameters: pre-test speed of 100 mm/min, test speed of 30 mm/min, post-test speed of 100 mm/min, penetration distance of 5 mm, and trigger force of 0.05 N. The average value was obtained for each test of 10 berries, and the results were reported in Newtons (N).…”

“…The content of MDA was determined using an MDA content kit (Suzhou Comin Biotechnology Co., Ltd., Suzhou, China) [ 4 ]. Specifically, 0.1 g of the sample was weighed and added to a 1 mL extract for ice bath homogenization and then centrifuged (4 °C, 8000× g , 10 min) in a high-speed refrigerated centrifuge (3K30, Sigma Company, Shanghai, China).…”

“…Its rich functional composition (polysaccharide, carotenoid, and betaine) makes it an ideal food and drug resource that can increase the human metabolism and regulate human immune functions [ 1 ]. At present, research reports mainly focus on the roles of chemical preservatives and diverse packaging strategies to improve the life and quality of stored fruit, including hydrogen sulfide fumigation [ 2 ], salicylic acid treatment [ 3 ], nitric oxide soaking treatment [ 4 ], heat treatment combined with chitosan coating [ 5 ], and lotus leaf extract composite coating [ 6 ]. The present application preservation technologies of fresh goji berries pose environmental challenges and lead to an accumulation of chemical residues.…”
