“…Many studies have confirmed the effects of storage duration and conditions on the quality of broccoli heads (Starzyńska et al 2003, Hasperué et al 2015, Vale et al 2015. According to Balouchi et al (2011), of the five broccoli cultivars compared in their study, after 40 days of storage at 0°C, four cultivars exhibited a significant increase in phenolic content, while a fall was observed in one of the cultivars.…”

“…In a study by Hasperué et al (2015), after 2 and 3 weeks of storage at 4°C, a significant decrease in total phenols was observed in primary broccoli heads, while in secondary heads the content increased, especially after the third week. A change in hydroxycinnamic acids content during storage at 4°C was reported by Vale et al (2015). According to the authors, the level of the acids increased until the fifth day of storage, and then it decreased to the lowest value after 12 days.…”

Biostimulants are commonly used in horticulture, primarily to increase yield quantity and quality, as well as plant tolerance to stress. The purpose of the study was to determine the effect of amino acid-based biostimulants and amino acids in combination with Ascophyllum nodosum filtrate, applied during the growing season on the phenolic content in broccoli heads both after harvest and after long storage in a cold store. The seedlings were planted in mid-July, and heads were harvested from September to October in each year of the study. Ascophyllum nodosum filtrate at a concentration of 1% was used during seedling production. The plants were watered with biostimulants twice, in the fourth and fifth week after sowing. They were also sprayed with amino acid-based biostimulants (1.5 dm 3 ha -1) three times, i.e. after the second, fourth and sixth week after planting. The biostimulants were not used in the control treatment. After harvest, the heads were stored for three weeks in a cold store at 1-2°C and 95% RH. Chemical analyses of total phenolic, caffeic, ferulic and sinapic acids, and of quercetin and kaempferol were carried out on samples of fresh broccoli and after the first, second and third week of storage. It was found that the application of biostimulants resulted in a significant increase in the total phenolic content, sinapic acid content, as well as quercetin content. Both in the control treatment and in the plants treated with the biostimulants, the concentration of all the tested phenolic compounds increased with the duration of storage.Ke y wor d s: amino acids, Ascophyllum nodosum filtrate, Brassica oleracea var. italica, kaempferol, phenolic acids, quercetin

“…However, information on specie-specific chilling sensitivity and respiration rates, together with the effects of cold storage on nutrient digestibility, bio accessibility of pro-health constituents and organoleptic quality of sprouts and microgreens, await further investigations in order to improve post-harvest methodologies. In 4-day-old soybean sprouts, the contents of isoflavones after a 7-day cold storage (4 • C) were generally equal or higher than in fresh sprouts [125], while 4 • C storage for more than 7 days revealed a significant decrease of glucosinolates in Brassica oleracea sprouts [152]. Plant species seem to play a pivotal role also in terms of dynamics of sprouts' microbiome during cold storage [153], but further investigations are still needed.…”

Sprouts and Microgreens: Trends, Opportunities, and Horizons for Novel Research

Sprouts and microgreens have attracted tremendous interest across multiple disciplines in recent years. Here, we critically review the most recent advances to underscore research prospects and niches, and related challenges, not yet addressed or fully pursued. In particular, we report a number of themes that merit special attention as a result of their relevance to plant science, nutrition, health, and zootechnics: (1) species not yet or inadequately investigated, such as wild plants, and fruit tree strains; (2) abiotic and biotic factors, and biostimulants, for elicitation strategies and metabolic engineering; (3) sanitization and processing technologies to obtain high-quality products; (4) digestive fate and impact of bioactive elements, antinutrients, and allergens on human nutrition; (5) experimental challenges to researching health benefits; (6) the opportunity to generate natural product libraries for drug discovery; and (7) sprouts in animal feeding to improve both animal health and the nutritional value of animal products for the human diet. The convergence of different themes involving interdisciplinary competencies advocate fascinating research pursuits, for example, the elicitation of metabolic variants to generate natural product collections for identification and selection of bioactive chemicals with a role as nutraceuticals, key constituents of functional foods, or interactive partners of specific drugs.

“…Firstly, the seeds were sterilised with 0.07% NaOCl, rinsed and soaked in distilled water for 10 h. The peat-based germination substrate (DSM 2w, from Kekkilä Garden Professional Substrate) was also sterilized at 90-95 °C for 1 h. The imbibed seeds were then spread in trays containing the substrate (Vale et al, 2015). Sprouting was performed 5, 7 and 9 days in a plant growth chamber , for the first 60 h at 24 °C, relative humidity 80%, lighting with 2 × 40W fluorescent lamps, and for the rest of time (60 h, 108 h and 156 h, respectively) at 22 °C, relative humidity 80% and lighting with 9 × 40W fluorescent lamps.…”

Sprouts are very rich in antioxidants (e.g. phenolic compounds) and their consumption is beneficial for humans' health. The sprouts' antioxidant properties are correlated to conditions of growth and maturity stage. The present study reveals the influence of maturity stage (5-, 7-and 9-day-old) and two sodium salts, NaCl and Na 2 SO 4 (10 mM and 100 mM) on the antioxidant capacity and total phenolic content of cauliflower and broccoli sprouts. The analysed sprouts' extracts were obtained in two phases, using ethanol 70% with 0.01% hydrochloric acid. In the case of cauliflower, the 7 days germination leads to the highest total phenolic content and radical scavenging capacity. Broccoli sprouts revealed the most enhanced DPPH radical scavenging capacity and total phenolic content at 5-day-old. The two sodium salts, generally, had positive effects on global antioxidant status. It is highlighted both for broccoli and cauliflower, the stimulating effect of 100 mM Na 2 SO 4 on the total phenolic content and soluble dry weight, but the DPPH radical scavenging activity was more important in the case of NaCl, than Na 2 SO 4 treatments, except for cauliflower sprouts treated with 100 mM Na 2 SO 4 . In conclusion, germination under adequate salt stress is a protocol to be considered in order to improve antioxidant properties of broccoli and cauliflower sprouts, despite the non-convenient effects on the germination and sprouts growth. Further researches are needed to optimize the level and time periods of such treatments.
