Brazil holds a series of favorable climatic conditions for agricultural production including the hours and intensity of sunlight, the availability of agricultural land and water resources, as well as diverse climates, soils and biomes. Amidst such diversity, Brazilian coffee producers have obtained various standards of qualities and aromas, between the arabica and robusta species, which each present a wide variety of lineages. However, temperatures in coffee producing municipalities in Brazil have increased by about 0.25 °C per decade and annual precipitation has decreased. Therefore, the agricultural sector may face serious challenges in the upcoming decades due to crop sensitivity to water shortages and thermal stress. Furthermore, higher temperatures may reduce the quality of the culture and increase pressure from pests and diseases, reducing worldwide agricultural production. The impacts of climate change directly affect the coffee microbiota. Within the climate change scenario, aflatoxins, which are more toxic than OTA, may become dominant, promoting greater food insecurity surrounding coffee production. Thus, closer attention on the part of authorities is fundamental to stimulate replacement of areas that are apt for coffee production, in line with changes in climate zoning, in order to avoid scarcity of coffee in the world market.

The presence of impurities in roasted ground coffee interferes with its quality. This Systematic Literature Review (SLR) aimed to identify and evaluate the different types of analytical techniques published in the last 20 years for the detection of adulterants in roasted coffee. The SLR was performed on StArt software in three stages: Planning, Executing, and Summarization. Eighty-three studies were selected for this review. The type of coffee most frequently studied was roasted ground coffee and Coffea arabica, while among the adulterants, Coffea canephora, coffee wastes, and corn. There was a trend toward applications of chromatographic, spectroscopic, and multi-adulterant techniques. Suitable techniques to detect/quantify adulterations in coffee and particularly as multi-detection approaches are crucial to improve coffee quality worldwide.

The term tree nuts is used to describe any nut that comes from a tree. The best known and most consumed are almond, Brazil nut, cashew, hazelnut, macadamia, pecan, pine nut, pistachio, and walnut. This consumption has led to their use in the development of plant-based beverages. This review aims to bring information reported in the literature on plant-based beverages made from tree nuts regarding health, technological, microbiological, sensory, and consumer aspects. The bibliographic search covered the articles published between the years 2000 and 2022. In total, 54 articles were selected for this review, which were categorized according to their thematic area as Food technology (n = 37); Nutrition and Health (n = 19); Microbiological aspects (n = 10); and Sensory and consumer studies (n = 12). It was observed that the most mentioned tree nuts were almond, cashew, hazelnut, and walnut, and the lowest mentioned were Brazil nut, macadamia nuts, pine nut, mallow nut, and sapucaia. Finally, this review observed that beverages represent beneficial nutritional and functional profile, but cannot be considered as a substitute, in their entirety, for dairy milk, except in the case of allergies to this food. Technological aspects proved to be positive for obtaining these beverages, with high pressure being the most advantageous. Considered safe and very promising from nutritional, industrial, environmental, and functional aspects.
