Abstract

Pea shoots (Pisum sativum L) are becoming increasingly popular as a vital health ingredient. Under controlled growth conditions, LED lights facilitate the germination process and improve the nutritional quality of vegetables. This study evaluated the influence of three LED light treatments: Red (625 nm); Blue (458 nm), Red / Blue (1:1) at 81 μmol/m²/s light intensity; for 10 days (16 h and 8 h darkness), and control (white light white light at 81 μmol/m²/s light intensity and darkness) during production on the phytonutritional composition and antioxidant activity of pea sprouts after 10 days of cold storage at 5 °C, 85 % RH.

Red/Blue LED exposure significantly increased the levels of ascorbic acid (0.6 mg/100 g), leucine (520.76 mg/100 g), phenylalanine (804.19 mg/100 g), lysine (154.05 mg/100 g), non-essential amino acids, carotenoids [lutein (33.74 mg/100 g), zeaxanthin (6.84 mg/100 g, trans-β-carotene (51.85 mg/100 g), cis β- carotenes (10.76 mg/100 g)], phenolic compounds [epicatechin (6.98 mg/100 g), ferulic acid (26.58 mg/100 g)] and antioxidant activity at harvest (day 0) than all other treatments. On day 4, however, leucine, phenylalanine, and lysine concentrations remained unchanged from harvest (day 0). On day 4, pea shoots grown under Red/Blue LED light had significantly higher lutein, zeaxanthin, trans and cis-β carotenes, epicatechin, and ferulic acid. Despite this, a moderately higher phytonutrient content is still achievable for up to 6 days of postharvest storage.

生产过程中LED光谱光组合可保存采后豌豆芽的植物营养成分

豌豆苗（Pisum sativum L）作为一种重要的健康成分越来越受欢迎。在受控的生长条件下，LED灯促进了蔬菜的发芽过程，提高了蔬菜的营养品质。本研究评估了三种LED光处理的影响：红色（625 nm）；在81 μmol/m2/s光强下，蓝（458nm）、红/蓝（1:1）；在5℃、85% RH条件下冷藏10 d后，豌豆芽的植物营养成分和抗氧化活性的变化（16 h、8 h黑暗）和对照（81 μmol/m2/s白光和黑暗）。红/蓝LED暴露显著提高了抗坏血酸（0.6 mg/100 g）、亮氨酸（520.76 mg/100 g）、苯丙氨酸（804.19 mg/100 g）、赖氨酸（154.05 mg/100 g）、非必需氨基酸、类胡萝卜素[叶黄素（33.74 mg/100 g）、玉米黄质（6.84 mg/100 g）、反式β-胡萝卜素（51.85 mg/100 g）、顺式β-胡萝卜素（10.76 mg/100 g）]、酚类化合物[表儿茶素（6.98 mg/100 g）、阿威酸（26.58 mg/100 g）]的含量和收获时（第0天）的抗氧化活性。然而，在第4天，亮氨酸、苯丙氨酸和赖氨酸的浓度与收获（第0天）相比保持不变。第4天，红/蓝LED光下生长的豌豆幼苗叶黄素、玉米黄质、反式和顺式β胡萝卜素、表儿茶素和阿魏酸含量显著增加。尽管如此，在采后6天的储存中，仍然可以获得较高的植物营养素含量。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
