Trends in research on cacti: the food of the future.

Cacti are a distinguished group of plants that stand out for their great nutritional values, diverse uses, and unique morphology, allowing them to grow and thrive under different conditions such as dry, xeric, and even low-temperature environments. The world is going through significant climate changes that are affecting the agriculture system. Therefore, sustainable and multifunctional crops, as many species of the Cactaceae family are, might be a good alternative in the near future. In this work, the uses of cacti in human food were analyzed through a scientific prospection from the point of view of their temporal and spatial distribution and potential uses. Brazil is the country with more publications related to the scope of this work, followed by Mexico. The presence of cacti in these countries can influence their interest in these species, which might reflect the results encountered in this study. The uses and ethnobotanical applications of cacti vary in different countries worldwide. Cactus is consumed fresh (in salads), in preparations (jams and sweets), and juices, being also present in traditional dishes in countries like Mexico. This study emphasizes cacti's importance in people's diets and ongoing world changes. Their ability to thrive even in hot environments with low water resources will lead to a greater focus on these species in the upcoming years. Furthermore, these plants have great flavor and contain several beneficial chemical compounds with desirable nutritional and health properties. Therefore, knowledge dissemination combined with technological innovations will allow greater use of these multifunctional species for human consumption. © 2024 Society of Chemical Industry.

Chia mucilage carrier systems: A review of emulsion, encapsulation, and coating and film strategies.

The use of carrier systems for the protection and delivery of bioactive compounds in the agri-food industry is an area of opportunity that requires the design of new systems and sources of materials for their structure. Chia seeds (Salvia hispanica L.) produce mucilage with functional qualities that allow their application in diverse areas of the food industry. These qualities have been used to form very stable carrier systems, such as capsules, emulsions, coatings, and films that can protect and prolong the functionalities of loaded compounds (e.g., antimicrobial and antioxidant capabilities). This paper presents a review of chia mucilage-based carrier systems and their applications in food products (micro-and nanoparticles, emulsions, coatings, and films for food packaging), as well as the current technological prospects of these systems. The use of chia mucilage in coatings and films shows a high potential for use in biodegradable, edible, and organic packaging. Although many studies have been conducted on chia mucilage encapsulation systems, there is still a gap in the application of capsules and particles in food.

Pachira aquatica (Malvaceae): An unconventional food plant with food, technological, and nutritional potential to be explored.

Pachira aquatica (Malvaceae) is an unconventional food plant (UFP) native to Mexico and found all over Brazil, where it is commonly known as monguba. It has an arboreal shape, exotic flowers, and a fruit similar to cocoa with several seeds. Although its main application is in urban ornamentation and folk medicine, monguba's fruit has a great potential for use in the food, pharmacology, cosmetic, and bioenergy industry, mainly due to its oil's characteristics. This review aims to compile the nutritional composition, bioactive and antioxidant activities, and technological and nutritional potential of monguba's seed, leaf, and fruit pericarp. It reviews studies of different databases between January 2018 and October 2021. Monguba seeds are rich in lipids, proteins, and minerals; the bark is rich in fiber; and all parts of the fruit have bioactive compounds. Discussing the use of UFP is a way of finding new alternative food sources, usually discarded, offering products with high nutritional value allied to technological and consumption potential, such as the monguba fruit.
