Item Analysis of the subtropical blackberry cultivar potential in jelly processing.(2014) Souza, Vanessa Rios de; Pereira, Patrícia Aparecida Pimenta; Pinheiro, Ana Carla Marques; Lima, Luiz Carlos de Oliveira; Pio, Rafael; Queiroz, FabianaIn Brazil, there are numerous blackberry cultivars under cultivation, however, only a few cultivars, such as the Guarani, are displayed/used for processing. In this context the aim of this work was to study the effects of different Brazilian blackberry cultivars (Guarani, Brazos, Comanche, Tupy, Cherokee, Caingangue, and Choctaw) on the physicochemical characteristics, texture profiles and the consumer acceptance of the resulting jelly to identify the potential use of these cultivars in the jelly industry. It is feasible to produce blackberry jellies with the Tupy, Comanche, Brazos, Guarani, and Choctaw cultivars because these jellies demonstrated good acceptability combined with good productivity. Consumers were shown to have a preference for a less adhesive, more acidic jelly. This study provides a useful insight about the Brazilian blackberry cultivar potential in jelly processing.Item Evaluation of the jelly processing potential of raspberries adapted in Brazil.(2014) Souza, Vanessa Rios de; Pereira, Patrícia Aparecida Pimenta; Pinheiro, Ana Carla Marques; Nunes, Cleiton Antônio; Pio, Rafael; Queiroz, FabianaGenerally raspberry products as jams, jellies, and preserves are made with red raspberry, however, yellow raspberry and especially black raspberry are also fruits adapted in Brazil, presenting even better productivity and quality. Thus, the aim of this study was to evaluate the processing potential of other varieties of raspberry, but the red, in the preparation of jellies through mixture design and response surface methodology (RSM). These techniques were used to optimize the following 3 variables: yellow (Golden Bliss cultivar, Rubus idaeus), black (Rubus niveus), and red raspberries (Batum cultivar, Rubus idaeus) to formulate a mixed raspberry fruit jelly through sensory evaluations. It was found that jelly formulated with a mix of colored raspberries grown in subtropical regions is a viable and alternative way to use yellow and black raspberries. The mixed raspberry jelly must have 0% to 30% yellow raspberries, 25% to 50% black raspberries, and 30% to 75% red raspberries. Within this region, the optimum formulation has ideal characteristics that are often not observed in formulations with 100% black or yellow raspberries.Item Influence of processing on the antioxidant capacity and bioactive compounds in jellies from different blackberry cultivars.(2015) Souza, Vanessa Rios de; Pereira, Patrícia Aparecida Pimenta; Teixeira, Taísa Rezende; Silva, Thais Lomônaco Teodoro da; Pio, Rafael; Queiroz, FabianaThe effect of thermal processing and the berry cultivar has been the subject of several studies, to serve as a basis for the least possible loss of bioactive compounds and antioxidant capacity. In Brazil, there are numerous blackberry cultivars under cultivation, and in this context, the aim of this work was to study how the bioactive compound contents and antioxidant capacity of blackberry jelly were influenced by the cultivars (Guarani, Brazos, Comanche, Tupy, Cherokee, Caingangue and Choctaw). Analysis was made of 7 fresh blackberry cultivars and 7 blackberry jelly formulations. Analysis of antioxidant activity, total phenolics, total anthocyanins and ascorbic acid was performed. It was verified that the contribution of the heat sensitive antioxidants compounds is considerable in all blackberry cultivars, and the degradation of these compounds was significantly different between the different blackberry cultivars. The Brazos and Caingangue cultivars stand out as undergoing the lowest losses in processing, resulting in jellies richer in bioactive compounds and higher antioxidant capacity.
