Conventional vs. Organic: Evaluation of Nutritional, Functional and Sensory Quality of .

Organic farming is growing rapidly worldwide since it is perceived as more respectful of the environment than conventional farming. In this sense, organic agriculture is highly appreciated by consumers since consumers around the world believe that organic food has a higher content of beneficial compounds for health and consider it of higher quality. For that reason, the objective of this research was to evaluate the nutritional, sensorial, and functional quality of the 'Fino 49' lemon grafted on in conventional and organic cultivation.

Preharvest treatments with malic, oxalic, and acetylsalicylic acids affect the phenolic composition and antioxidant capacity of coriander, dill and parsley.

The effects of a preharvest treatment with malic (MA), oxalic (OA), or acetylsalicylic (ASA) acid at three concentrations (1, 2 and 3mM) on the bioactivity and antioxidant capacity of coriander, dill, and parsley were investigated. The antioxidant capacity of the herbs extracts was assayed by spectrophotometric methods by using three different analytical methods: ORAC, FRAP, and ABTS; the effects of treatments were very positive in coriander, produced intermediate results in dill, and no effects were found in parsley plants. Polyphenol compounds were identified by LC-MS-QTof and quantified by UPLC-PDA-FL.

Volatile Composition of Essential Oils from Different Aromatic Herbs Grown in Mediterranean Regions of Spain.

Volatile composition of essential oils from dill, parsley, coriander, and mint were investigated at different harvest dates to determine the most suitable harvest time for each these herbs. Hydrodistillation (HD), using a Deryng system, was used for isolating the essential oils. Isolation and identification of the volatile compounds were performed using gas chromatography-mass spectrometry (GC-MS) instrument.

Irrigation dose and plant density affect the volatile composition and sensory quality of dill (Anethum graveolens L.).

Background: Two independent field experiments were carried out to investigate the influence of (i) three irrigation treatments (ID0 = 1585 m ha , considered as a control; ID1 = 1015 m ha ; and ID2 = 2180 m ha ) and (ii) three plant density treatments (PD0 = 5.56 plants m , considered as a control; PD1 = 4.44 plants m ; and PD2 = 7.
