Acetaldehyde, ethanol and non-protein bound amino acids were determined in broccoli florets (Brassica oleracea L. var. Italica cv. Marathon) stored for 7 days at 10°C in air or controlled atmospheres (0.125, 0.25, or 0.5% O2 alone or in combination with 20% CO2, or 20% CO2 in N2) followed by 2 days aeration. Floret yellowing was visible at days 7 and 9 in air. Low O2 or low O2 plus high CO2 atm...

Cauliflower (Brassica oleracea var. botrytis) and broccoli (B. oleracea var. italica) differ in the developmental stage of the reproductive meristem at harvest. A cauliflower head is formed by arrest at the inflorescence meristem stage and broccoli at the flower bud stage, and the horticultural value of the crop depends on synchronous development across the head. In other plant species, gibbere...

1 Chicken and water chestnuts A case-based planner devises new plans by retrieving and adapting old ones from memory (see, e. Ideally, the plan it retrieves from memory should be one that requires the least adaptation to t the current circumstances. Finding this plan in a cost-eeective way is thus a key issue in case-based reasoning (see, e. The approach that is generally taken to this problem ...

The purpose of this study was to reveal the changes in total phenolic content and antioxidant capacity broccoli, an untargeted metabolomics approach developed investigate effect lactic acid bacteria fermentation on metabolome broccoli florets. results showed that significantly increased after fermentation. metabolite profile main chemical components fermented unfermented are lipids lipid-like m...

Effect of pre-harvest methyl jasmonate (MeJA) and post-harvest 1-methylcyclopropene (1-MCP) treatments on broccoli floret glucosinolate (GS) concentrations and quinone reductase (QR, an in vitro anti-cancer biomarker) inducing activity were evaluated two days prior to harvest, at harvest and at 10, 20, and 30 days of post-harvest storage at 4 °C. MeJA treatments four days prior to harvest of br...

Isobutyrate-1-(14)C and l-isoleucine-U-(14)C fed through the petiole labeled the surface lipids of broccoli leaves, but the incorporation was much less than from straight chain precursors. Not more than one-third of the (14)C incorporated into the surface lipids was found in the C(29) paraffin and derivatives, whereas more than two-thirds of the (14)C from straight chain precursors are usually ...

This paper gives an overview of the epidemiological data concerning the cancer-preventive effect of brassica vegetables, including cabbage, kale, broccoli, Brussels sprouts, and cauliflower. The protective effect of brassicas against cancer may be due to their relatively high content of glucosinolates. Certain hydrolysis products of glucosinolates have shown anticarcinogenic properties. The res...

The consumption of vegetables belonging to the family Brassicaceae (e.g., broccoli and cauliflower) is linked to a reduced incidence of cancer and cardiovascular diseases. The molecular composition of such plants is strongly affected by growing conditions. Here we developed an unbiased metabolomics approach to investigate the effect of light and dark exposure on the metabolome of broccoli sprou...

Folate intake is strongly influenced by various methods of cooking that can degrade the natural forms of the vitamin in foods. The aim of the present study was to determine the effect of different cooking methods on folate retention in various foods that contribute to folate intake in the UK diet. Typical purchasing and cooking practices of representative food folate sources were determined fro...

Epidemiological evidence has suggested that consumption of a diet rich in cruciferous vegetables reduces the risk of several types of cancers and chronic degenerative diseases. In particular, broccoli sprouts are a convenient and rich source of the glucosinolate, glucoraphanin, which can release the chemopreventive agent, sulforaphane, an inducer of glutathione S-transferases. Two broccoli spro...
