“…Due to their inherent functions, fruits and vegetables do not lose their respiration and cellular activity directly after harvesting. 1 Blueberries are grown in large quantities, are highly nutritious, and are a respiratory leapfrog fruit. After picking, blueberries do not lose their respiration and cellular activity directly after picking but continue to perform their basic functions for a period of time due to their own functions.…”

In order to extend the shelf life of fruits and vegetables, a sodium alginate-sodium carboxymethyl cellulose composite film loaded with poly(vinyl alcohol) microcapsules was prepared in this paper. The optimal film substrate ratios were obtained after the response surface optimization. Poly(vinyl alcohol) microcapsules were prepared, clove essential oil was loaded into them to investigate the effects of microcapsules on the composite film properties, and the microcapsule composite film with the best overall performance was selected to be applied to blueberry preservation. The results showed that the composite film of 0.84% sodium alginate, 0.25% sodium carboxymethyl cellulose, and 0.56% glycerol presented excellent mechanical properties after adding 1.75% microcapsules. It had a good inhibitory effect on Escherichia coli, Staphylococcus aureus, and Penicillium and had a DPPH clearance rate of 83.78%. The low-temperature bonded composite film could slow down the respiration rate of blueberry, inhibit browning and water loss, effectively maintain the quality of blueberry, and have a significant preservation effect on the anthocyanin and soluble solid content of blueberry. The clove essential oil slow-release microencapsulated composite film can be used for blueberry preservation.

“…All these features of humic acid would improve the yield of the product, as well as their quantity and quality. In this sense, several studies have been performed on the effect of humic acid on the yield of different plants [16][17][18][19][20][21], but little information is available about the interaction between HA and bioactive compounds and the effects of these interactions on physiological or biochemical processes.…”

Lettuce (Lactuca sativa L., Asteraceae) is a popular vegetable leafy crop playing a relevant role in human nutrition. Nowadays, novel strategies are required to sustainably support plant growth and elicit the biosynthesis of bioactive molecules with functional roles in crops including lettuce. In this work, the polyphenolic profile of lettuce treated with glutamic acid (GA), humic acid (HA), and their combination (GA + HA) was investigated using an untargeted metabolomics phenolic profiling approach based on high-resolution mass spectrometry. Both aerial and root organ parts were considered, and a broad and diverse phenolic profile could be highlighted. The phenolic profile included flavonoids (anthocyanins, flavones, flavanols, and flavonols), phenolic acids (both hydroxycinnamics and hydroxybenzoics), low molecular weight phenolics (tyrosol equivalents), lignans and stilbenes. Overall, GA and HA treatments significantly modulated the biosynthesis of flavanols, lignans, low molecular weight phenolics, phenolic acids, and stilbene. Thereafter, antioxidant capacity was evaluated in vitro with 2,2-diphenyln-1-picrylhydrazyl (DPPH), 2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), and cupric ion reducing antioxidant capacity (CUPRAC) assays. In addition, this study examined the inhibitory properties of enzymes, including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), tyrosinase, alpha-amylase, and alpha-glucosidase. Compared to individual treatments, the combination of GA + HA showed stronger antioxidant abilities in free radical scavenging and reducing power assays in root samples. Moreover, this combination positively influenced the inhibitory effects of root samples on AChE and BChE and the tyrosinase inhibitory effect of leaf samples. Concerning Pearson’s correlations, antioxidant and enzyme inhibition activities were related to phenolic compounds, and lignans in particular correlated with radical scavenging activities. Overall, the tested elicitors could offer promising insights for enhancing the functional properties of lettuce in agricultural treatments.

“…In addition, the excessive use of fertilizers in soils causes erosion and salinity, accumulation of heavy metals, eutrophication of water, and accumulation of nitrates (Rahman and Zhang, 2018), therefore, the search for ecological solutions that increase the efficiency of plant production and decrease the use of synthetic chemicals has become essential (Stasińska-Jakubas and Hawrylak-Nowak, 2022). In recent years, the use of biostimulants has been an alternative to the application of synthetic fertilizers (Nunez et al, 2023), since these, in addition to having increased their costs, cause damage to human and animal health and the environment (Torres-Rodriguez et al, 2021;Dupouy, 2023). A biostimulant is an agrochemical product formulated with mixtures of natural substances and/or microorganisms that applied to plants, improve the efficiency of mineral nutrition, tolerance to abiotic stress (salinity, drought, high temperatures, heavy metals, among others), and biotic and/or crop yield, or improve the quality characteristics of crops (Rouphael and Colla, 2020;García-Sánchez et al, 2022).…”

Biostimulants improve the absorption and assimilation of nutrients by plants, making them more tolerant to biotic or abiotic stress, improving their agronomic characteristics. Natural and biodegradable biostimulants such as chitosan have fungal and bactericidal activities and promote growth and crop yield, this is why, to evaluate the effect of chitosan application on growth and productive parameters of broccoli (Brassica oleracea L.), three concentrations of chitosan (T1 = 500 mg.L-1; T2 = 1000 mg.L-1; and T3 = 2000 mg.L-1) and a control treatment (T4 = distilled water), were applied by foliar spray when the true leaves unfolded, using a completely randomized design with 30 repetitions per treatment. The variables height of the plant, number of leaves per plant, diameter of the flowering stalk, diameter of the flowering head, length of the flowering stalk, total length of the flowering stalk, fresh biomass of the flowering head, of the root, and of the aerial part, total dry biomass and yield were measured. All the variables increased (P<0.05) as the chitosan dose increased, concluding that the application of chitosan to the broccoli crop is a viable alternative as a substitute for synthetic fertilizers.
