Summary: This study characterized the honeys of Babors Kabylia through sensory, melissopalynological, and physico-chemical parameters. The honey samples showed high quality with diverse botanical origins. Differentiation of honey samples was achieved based on representative pollen types, sensory properties, and physico-chemical components.

Summary: The physico-chemical quality aspects of honey from northeastern Ethiopia were studied. Data analysis using R software revealed that the moisture, ash, acidity, diastase, sucrose, and pH contents were within the limits set for honey quality standards. However, the HMF and reducing sugars did not meet the European standard. Improvement is needed to make the honey exportable to the international market.

Summary: This study focused on the taxonomic inventory of the Eumorpha genus in Maranhao, Brazil and found that the number of Eumorpha species in the region is underestimated. The study also demonstrated that the use of external morphology alone for identification is not effective for the analyzed species complexes, highlighting the importance of genitalia characters in species differentiation.

Summary: The study investigated the physico-chemical properties of honey produced from stingless bees in the Oromia Region of Ethiopia. The mean values of parameters for honey samples were analyzed, and significant differences were found in moisture content, total acidity, and HMF compared to the standard parameters of Apis mellifera honey in Ethiopia. This study calls for further research on the nutritional and medicinal values of stingless bee honey in Ethiopia in order to establish specific standards.

Summary: This study aimed to determine the chemical composition and physical characteristics of the step gradient ethanol precipitates of celluclast-assisted hydrolysate from Sargassum thunbergii (STCFs). The yields of STCFs were STCF1 3.78 ± 0.01 %, STCF2 1.13 ± 0.06 %, and STCF3 0.17 ± 0.05 %. Polysaccharide and sulfate contents significantly increased in STCF1 and STCF2 but decreased in STCF3. Their physical characteristics were determined via FTIR, SEM, MALS, and MS. FTIR showed that STCF1 and STCF2 have specific S-O, C-O-S bonds in sulfate, while STCF3 has a specific C-O bond in glucan.

Summary: This study investigated the botanical origin, physicochemical profile, and biological activities of geopropolis from M. scutellaris collected during rainy and dry seasons. The results showed that rainy-season geopropolis had higher phenol and flavonoid content and exhibited superior antioxidant, antimicrobial, and anti-inflammatory activities compared to dry-season geopropolis.

Summary: Different cooking methods affected the physico-chemical, flavor, and sensory characteristics of shrimp. Boiling+roasting, steaming+roasting, and microwaving+roasting improved the texture and increased the brightness of the shrimp. Steaming+roasting also increased the proportion of sweet amino acids in the shrimp and enhanced the umami and richness detected by an electronic tongue.

Summary: Spodumene concentrate from the Pilbara region in Western Australia was characterized and studied for its major minerals, particle sizes, thermal behavior, and polymorph transformations. The study found that temperature significantly influences the transformation of spodumene polymorphs, with 1000 degrees Celsius suggested as the ideal processing temperature. The application of a first-order kinetic model yielded kinetic parameters confirming the strong temperature dependence for the spodumene polymorph transformations.

Summary: This research project investigated the physico-chemical, sensory, hygienic, and safety characteristics of raw goat milk, whey, brine, and traditional goat cheese during the ripening period. The results showed significant changes in the cheese's characteristics, including increased bitterness, intensified odor, and mold development, after a certain period of ripening. The study also highlighted the need for improved hygiene in the production processes and active monitoring of microbial safety in traditional foods.

Summary: In smallholder communal farming systems, Nguni people slaughter goats using indigenous methods which have cultural and spiritual significance to them, to assess meat physico-chemical characteristics parameters. Different slaughter methods have an impact on the meat texture and color of Nguni wethers, with some methods potentially resulting in fresher meat appearance.
