RELATION BETWEEN QUALITY AND PRICE OF 'GOLDEN DELICIOUS' APPLES IN BELGIUM
The apples have been tested on organoleptic and visible quality. For the organoleptic quality the most important criteria were taste, refractometer index, firmness, colour, juiciness, resonance and wrinkles. The visible quality was determined by factors like russeting, mean weight of the apples, variation in weight and packing.
The relations between the different factors have been determined by calculating single correlations. The following conclusions emerged from the research:
- no relation existed between price and quality;
- a strong relation existed between price and mean weight of the apples;
- the price of apples is highly dependent on the more or less luxurious character of the shop and the selling policy of the shopkeeper;
- a significant correlation was found between taste and mean weight, wrinkles, refractometer index and resonance;
- a highly significant correlation existed between mean weight and refractometer index and between refractometer index and firmness.
The main conclusion is that the price is irrelative to quality. Quality has to be determined by considering shape, size and colour of the apples.
