Abstract
Strawberries are berry-type fruits that are very popular and widely consumed all over the world. The sensorial, physical-chemical and nutritional characteristics of strawberries are parameters of quality that influence the choices of consumers. However, these characteristics may be influenced by intrinsic and extrinsic factors that alter the fruit quality. The concentrations of nutrients and other chemical compounds in strawberries may increase and/or decrease according to the cropping system, maturation stage, climatic conditions, and preservation and storage methods. Factors characteristic of the cultivar, such as the genetic profile, may also influence the composition of strawberries. In this context, the objective of this research was to evaluate the sensorial, physical-chemical and nutritional characteristics of different strawberry cultivars to identify the genotype(s) with the best characteristics for commercialization and human consumption. The day-neutral strawberry cultivar "Aromas" and short-day strawberry cultivars "Camarosa, Camino Real, Dover, Sweet Charlie, and Tudla" were cultivated in the Olericultura Sector of the State University of the Midwest (UNICENTRO), Paraná State, Brazil. The fruits were characterized in relation to their physical-chemical, nutritional and sensorial aspects. According to the sensorial profiles, the Camarosa, Camino Real, Dover, and Tudla genotypes showed greater acceptability among consumers. Camarosa, Sweet Charlie, and Tudla presented better physical-chemical characteristics for human consumption, while the cultivars Camarosa, Dover, and Tudla had the best nutritional contents. In general, it is concluded that the genotypes Camarosa and Tudla are the most favourable for human consumption, according to their sensorial, physical-chemical and nutritional characteristics.
Highlights
IntroductionChina and the United States stand out among the largest strawberry producers, at 3,801,865 tonnes year-1 (141,498 ha) and 1,420,570 tonnes year-1 (21,242 ha), respectively
In strawberries treated with an edible coating based on gum arabic, the acceptability was higher (p < 0.05) than that for uncoated fruit (Tahir et al, 2018)
The positive effect of appearance on acceptability was confirmed for the cultivars Dover and Tudla and did not occur for Camarosa, Camino Real or Sweet Charlie
Summary
China and the United States stand out among the largest strawberry producers, at 3,801,865 tonnes year-1 (141,498 ha) and 1,420,570 tonnes year-1 (21,242 ha), respectively. Fresh strawberries account for 80% of the world production, while the remainder is destined for industrial processing for the preparation of yogurts, jams, jellies and wine (Paparozzi et al, 2018). Considering this aspect, strawberry is one of the most studied genomic and agronomic berries due to its commercial, industrial and economic impacts (Giampieri, Alvarez-Suarez, & Battino, 2014)
