Development of Araticum (Annona crassiflora Mart.) jams: evaluation of physical, microbiological, and sensorial stability in different packages

Araticum is an exotic fruit with unique sensory features and also high nutritional value characteristics. This study aimed to develop araticum jams with substitution of commercial pectin for passion fruit albedo, as well as to evaluate its physical, microbiological and sensorial stability during storage in polyethylene and polypropylene packages. Samples were analyzed at 25 and 35 °C for 130 days. During the storage the values of pH (3.5-4.9), titratable acidity (0.27-0.62%), color (L* 20.56-28.49, a* 1.32-7.03, and b* 1.32-9.29), chroma (1.86-11.65), hue (0.60-1.03), soluble solids (68-79.70 ºBrix), reducing sugars (12.60-60.30%), non-reducing sugars (6.22-56.19%), total sugars (55.30-96.30%), and carotenoids (0.21-1.27 mg.100 g-1) varied. The indicated shelf life was approximately 117 and 65 days for jams in polypropylene package, and 112 and 63 days for those kept in the polyethylene package, when the temperature of storage was 25 and 35 ºC, respectively. Araticum fruit is a good source for jams, that can contribute to the increased insertion of foods of better nutritional value in the consumer market.

Pharmaceutical, food potential, and molecular data of Hancornia speciosa Gomes: a systematic review

Hancornia speciosa Gomes is a fruit and medicinal tree species native to South America, which in Brazil is considered of potential economic value and priority for research and development. We present a map of the state-of-art, including articles, patents, and molecular data of the species to identify perspectives for future research. The annual scientific production, intellectual, social, and conceptual structure were evaluated, along with the number of patent deposits, components of the plant used, countries of deposit, international classification and assignees, and the accessibility of available molecular data. Brazil has the most significant publications (306) between 1992 and 2020. Technological products (29) have been developed from different tissues of the plant. Most of the articles and patents were developed by researchers from public universities from different regions of Brazil. The molecular data are sequences of nucleotides (164) and proteins (236) of the chloroplast genome and are described to identify the species as DNA barcodes and proteins involved in photosynthesis. The compilation and report of scientific, technological, and molecular information in the present review allowed the identification of new perspectives of research to be developed based on the gaps in knowledge regarding the species and perspectives for the definition of future research.
