| Title : | ORGANOLEPTIC AND QUALITY PROPERTIES OF TOMATO FRUITS UNDER TREATMENT WITH MICROALGAE EXTRACTS |
| Abstract : | The quality parameters of tomatoes can vary depending on different factors, including cultivar, fruits maturity stage, fertilisation and growing conditions. The research aimed to the evaluation of the organoleptic and quality properties of tomato fruits under treatment with microalgae extracts. Tomatoes (cultivar ‘Belle’ F1, Enza Zaden) were grown in peat (producer Laflora LTd, pHKCl 5.5) in the conditions of polycarbonate greenhouse. From seedlings planting till start of harvesting plants were sprayed weekly (for a total of five times) with the solution of ethanol extractions of different microalgae species: Spirulina sp., Dunaliella sp., Chlorella sp., two concentrations of the extracts were compared with sprays with corresponding ethanol solution as a control. In total, nine plants per treatment were used. Yield was harvested 13 times from 30/09 till 23/12 once per week at the stage of full ripen. Colour components of L*, a*, b*, organoleptic properties, taste index and maturity index were determined. No negative effects of any tested treatments on organoleptic and quality properties as well as fruits` shape, diameter, number of locules were determined for tomato yield. Different fruit parameters including shape, diameter, number of locules, taste index and maturity index were determined. No negative effects of any tested treatments on organoleptic and quality properties as well as of tomato fruits were observed. Maturity index was higher for control treatment with drinking water (17.60), but the highest taste index (0.57) was observed for variant with Spirulina, concentration 10% v/v. The effect of microalgae extract on the organoleptic indicators of the fruit was not detected, which can be evaluated positively, and this moment indicates the stability of the cultivar. |
