Summary: Current models of floral nectar production do not consider the contribution of photosynthesis by green nectary tissue, but research on manuka flowers showed that photosynthesis in green nectaries affects nectar sugar production and composition. Factors like light, temperature, and inhibitors were found to influence nectar production and content.

Summary: Leptospermum scoparium is the basis of a flourishing honey industry in Aotearoa New Zealand and Australia. Genetic analysis shows that Tasmanian L. scoparium has distinct genetic traits from NZ manuka, suggesting that it should be recognized as a separate, endemic Australian species. However, within NZ, L. scoparium exhibits genotypic variation with a north to south landscape pattern, indicating support for isolation by distance and minimal genetic differentiation between geographic groups.

Summary: New Zealand manuka honey is a premium food product but its high demand has led to counterfeit products. Researchers developed a method using unique nectar-derived proteins as markers to determine the authenticity of manuka honey. By analyzing the relative abundance of these markers in manuka and non-manuka honey samples, they found that manuka honeys had distinct peptide markers while non-manuka honeys did not, demonstrating the potential of peptide profiling as a more robust approach for authentication.

Summary: This study utilized proteomics to analyze the protein components of ma?nuka honey, identifying 50 bee-derived proteins with major royal jelly proteins as the predominant ones. Unique nectar-derived proteins in ma?nuka honey were also discovered, along with the presence of plant proteins and proteins related to drought tolerance. Authentication markers were proposed based on the uniqueness of certain peptides, showcasing peptide profiling as a novel approach for ma?nuka honey authentication.

Summary: The elemental concentrations in soils may influence the antimicrobial properties of manuka honey, with certain elements showing negative correlations with MGO levels. There were no clear correlations between honey, plants, and soils for individual elements, except for potassium. Additionally, soil fertility may play a role in determining manuka honey quality due to its negative correlation with MGO and DHA concentrations.

Summary: Manuka honey is important in medical applications due to its antibacterial, antiviral, and antibiotic properties. However, there is limited information about its physicochemical characteristics and pollen composition. In this study, the diastase number (DN), hydroxymethylfurfural (HMF) content, and melissopalynological analysis of manuka honey were examined. The research found a variation in Leptospermum scoparium pollen percentage and a low DN in commercially available manuka honey, suggesting questionable quality.

Summary: Manuka leaves rich in p-caryophyllene were extracted using menthol:lactic acid HDES, ethanol, and n-hexane to compare total phenolic content and antioxidant activity. Ethanol extract had the highest TPC, while HDES showed promising results and n-hexane had poor yield. The antibacterial effects of Manuka extract by HDES were also evaluated, demonstrating potential for broader industrial applications.

Summary: The high demand for therapeutic honey has led to the establishment of Leptospermum nectar plantations. Research has found that L. polygalifolium and L. scoparium are highly amenable to propagation as rooted cuttings, with or without the use of indole-3-butyric acid (IBA). Although IBA can increase the number of roots, it does not significantly affect the average rooting percentages of the two species.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

Summary: Horse's milk, with its high nutritional value and low allergenic proteins, could be a substitute for cow's milk in infant consumption. A proteomic method was used to identify and compare milk fat globule membrane (MFGM) and whey proteins from different horse breeds. The study found differences in protein composition and functionality, which could support the development of formulas more suitable for human infants.

Summary: This study investigates the impact of milling on the active components in rice, with a focus on the stability and bioaccessibility of phenols, VB1, and alpha-GABA during cooking and digestion. The findings show that milling exacerbates the instability of gamma-GABA during cooking and VB1 during digestion, and it affects the bioaccessibility of these active compounds.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
