Abstract
The effect of controlled atmospheres on quality of manually and mechanically harvested chestnuts was investigated.
Mechanical harvesting was conducted by using a modified self-propelled vacuum harvester.
The modification consisted in upholstering with a high density foam the internal components of the vacuum system.
Fruits were treated with water-curing and stored for two months.
Parameters such as weight loss, color, firmness, acetaldehyde and ethanol concentration, soluble solid and sensory quality were analyzed.
Sensorial descriptive data was subjected to principal component analysis (PCA), resulting in a multidimensional space that was related to the consumer acceptance.
The results indicated that the effects on sensorial quality and storability were slightly dependent on the harvest method used.
Manual harvest was the best harvesting method due to the lower incidence of damage and cracks on the fruit, but the new upholstering system seems to be very effective.
