Abstract
Microgreens have recently gained popularity owing to their reliable economic and nutritional value. This study aimed to increase the quality of microgreen broccoli via treatment with different concentrations (1%, IPB-1; 3%, IPB-3; 5%, IPB-5; or 7%, IPB-7 w/v) of illite—a natural mineral powder. The results showed that the illite treatments considerably increased the content of mineral elements, such as Ca, P, and K; of vitamin C; and of free amino acids; and also increased the total weight of the broccoli sprouts. The content of sulforaphane, a bioactive compound, also increased by up to 47% with illite treatment, with the highest increase being in the IPB-5 group. However, several of the parameters were lower in the IPB-7 group. Aromatic compounds were categorized by functional groups such as hydrocarbons which numbered 36, 30, 34, 28, and 30 in the control, IPB-1, IPB-3, IPB-5, and IPB-7 groups, respectively. We found 16, 15, 15, 13, and 14 sulfides, including dimethyl sulfide, in the control, IPB-1, IPB-3, IPB-5, and IPB-7 groups, respectively. Additionally, aldehydes, comprising seven compounds, were detected in the IPB-1, IPB-3, IPB-5, and IPB-7 groups. Illite treatment significantly increased the activities of antioxidants such as DPPH and the polyphenol content of the microgreens. These results indicate a potential role for appropriate illite doses in microgreen treatment to address multinutrient deficiencies and to increase the quality of microgreen vegetables.
期刊介绍:
Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
