“…To overcome the aforementioned challenges, the swirling fluidized bed drying (SFBD) is a new and simple design of the drying process that uses homogenous and quick drying, making it a great option for drying heat‐sensitive compounds like gingerols (Abdul Halim et al, 2022). Our preliminary design of SFBD was developed by Abdul Halim et al (2020). It was observed that the 67° swirling distributor had the best drying performance across all velocities without a negative impact on the stingless bee pot‐pollen nutrients.…”

This study presents the effect of different drying techniques (swirling fluidized bed drying [SFBD], oven drying [OD], and freeze drying [FD]) on the drying kinetics, antioxidant potential, and 6-gingerol concentration of Bentong ginger (BG). Seven mathematical models were applied to the experimental data to determine the best thinlayer drying models for drying applications Interaction between the drying methods and antioxidant properties has been evaluated using correlation coefficient (R). The Midilli-Kucuk model showed the best fit at explaining the thin layer drying behavior of the BG for OD and SFBD, whereas the Page model showed the best fit for FD. Correlation analysis revealed that the drying methods had a strong positive correlation with DPPH and a moderate negative correlation with 6-gingerol concentration and total phenolic content. The experimental results showed that SFBD reduces the total drying time compared to OD and FD, which translates to a low energy consumption, high drying rate, and moisture diffusivity. In addition, the dried BG sample from the SFBD exhibited a slightly higher DPPH inhibition and total phenolic yield as well as the best option to preserve the 6-gingerol compound in the Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometry (LC-QTOF/MS) analysis.Thus, the SFBD approach proved to be a feasible method for drying ginger. Practical applicationsGinger is considered to be highly perishable foods due to their high moisture content.The most common process for keeping shelf-stable ginger is dehydration. Drying preserves the quality of ginger by lowering the moisture level, which prevents microbial growth and chemical changes during dried storage. The use of fluidized bed (FBD) dryers for agricultural products processing has grown in popularity in recent years.The modified and hybrid FBD systems were observed to be efficient for drying food products in previous studies. The outcome of this research showed that SFBD techniques attain better nutritional quality of ginger through less energy consumption and processing time.

Stingless bees belong to the Meliponini tribe and are widely distributed in the tropics and subtropics, where they perform important ecological services. Among the best distributed groups of stingless bees is the genus Scaptotrigona, which includes 22 species distributed throughout the neotropical region, including the area from Mexico to Argentina. Bees of this genus are responsible for the production of products such as honey, propolis, geopropolis and fermented pollen (“saburá”). This review aimed to provide an overview of the chemical composition and biological activities associated with derived products from stingless bees of the genus Scaptotrigona. The bibliographic review was carried out through searches in the Scopus, Web of Science, ScienceDirect and PubMed databases, including publications from 2003 to January 2023. The study of the chemodiversity of products derived from Scaptotrigona demonstrated the mainly presence of flavonoids, phenolic acids, terpenoids and alkaloids. It was also demonstrated that products derived from bees of the genus Scaptotrigona exhibit a wide range of biological effects, such as antibacterial, antioxidant, anti‐inflammatory and antifungal activities, among other bioactivities. This review provides an overview of phytochemical and pharmacological investigations of the genus Scaptotrigona. However, it is essential to clarify the toxicity and food safety of these products.
