Organic versus conventional tomatoes: influence on physicochemical parameters, bioactive compounds and sensorial attributes.
نویسندگان
چکیده
The effect of organic and conventional agricultural systems on the physicochemical parameters, bioactive compounds content, and sensorial attributes of tomatoes ("Redondo" cultivar) was studied. The influence on phytochemicals distribution among peel, pulp and seeds was also accessed. Organic tomatoes were richer in lycopene (+20%), vitamin C (+30%), total phenolics (+24%) and flavonoids (+21%) and had higher (+6%) in vitro antioxidant activity. In the conventional fruits, lycopene was mainly concentrated in the pulp, whereas in the organic ones, the peel and seeds contained high levels of bioactive compounds. Only the phenolic compounds had a similar distribution among the different fractions of both types of tomatoes. Furthermore, a sensorial analysis indicated that organic farming improved the gustative properties of this tomato cultivar.

The influence of organic and conventional cultivation systems on the nutritional value and content of bioactive compounds in selected tomato types.
BACKGROUND Tomato fruits contain a high level of antioxidants such as vitamin C, polyphenols (including flavonoids), and carotenoids (such as lycopene and β-carotene). Some studies have shown the higher level of bioactive compounds in organically produced tomato fruits compared to conventional ones, but not all studies were consistent in this respect. The levels of carotenoids and phenolics are...
متن کاملEffect of Flaxseed (Linum usitatissimum) Mucilage on Physicochemical and Sensorial Properties of Semi-Fat Set Yoghurt
In the present study, the effect of addition of flaxseed mucilage on the physicochemical and sensorial properties of semi-fat (1.5% fat) set yoghurt was evaluated. Yoghurt samples were incorporated with flaxseed mucilage at the levels of 0.00, 0.10, 0.15, and 0.20% and analyzed periodically for pH value, titrable acidity, viscosity, consistency, water holding capacity, syneresis, colour paramet...

متن کاملEffect on Quality Characteristics of Tomatoes Grown Under Well-Watered and Drought Stress Conditions
Tomatoes are one of the most nutritionally and economically important crops in New Zealand and around the world. Tomatoes require large amounts of water to grow well and are adversely affected by drought stress. However, few studies have evaluated the physicochemical characteristics of commercial tomatoes grown under water stress conditions. Four tomato cultivars (Incas, Marmande, Scoresby Dwar...
