Summary: This study investigated the occurrence, distribution, and associations of various elements in the inner and outer parts of Pachyma hoelen sclerotia in Southern China. The quality of forest and agricultural soil was found to be the main factor determining the occurrence of minerals in sclerotia. The concentration of elements was generally higher in the outer part compared to the inner part, except for silver. Additionally, there were different association patterns of elements in different morphological parts of the sclerotia. Further research should be conducted to assess the relationship between minerals and bioactive organic compounds produced by P. hoelen.

The digestion fates of lipids with different unsaturated levels in people with different age groups

Yanan Wang, Jiachen Shi, Yong-Jiang Xu, Chin-Ping Tan, Yuanfa Liu

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.

Fabrication and characterization of chitosan-pectin emulsion-filled hydrogel prepared by cold-set gelation to improve bioaccessibility of lipophilic bioactive compounds

Hyunjong Yu, Huisu Kim, Pahn-Shick Chang

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.

Identification and comparison of milk fat globule membrane and whey proteins from Selle Français, Welsh pony, and Tieling Draft horse mare's milk

Kunying Lv, Yixin Yang, Qilong Li, Ran Chen, Liang Deng, Yiwei Zhang, Ning Jiang

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.

Phenols and saliva effect on virgin olive oil aroma release: A chemical and sensory approach

Enrique Jacobo Diaz-Montana, Helene Brignot, Ramon Aparicio-Ruiz, Thierry Thomas- Danguin, Maria Teresa Morales

Summary: Sensory perception of virgin olive oil is influenced by phenols and volatiles, which are affected by the composition of the oil and biological factors. This study investigated the effect of saliva and phenols on the release of volatiles, and found that the presence of phenols decreased the release of saturated volatiles.

Tonghao Du, Yazhou Xu, Xiaoyan Xu, Shijin Xiong, Linli Zhang, Biao Dong, Jinqing Huang, Tao Huang, Muyan Xiao, Tao Xiong, Mingyong Xie

Summary: This study successfully improved the ACE inhibitory activity of black sesame seeds by fermenting them with Lactobacillus Plantarum NCU116 and hydrolyzing them using acid protease. The RF-PSO model was used to predict the ACE inhibitory activity during the hydrolysis process. Eight peptides with ACE inhibitory activity were identified from fermented black sesame seed hydrolysates after separation and screening.

Mechanism of aroma enhancement methods in accelerating Congou black tea acidification subjected to room temperature storage

Zixuan Xie, De Zhang, Junyu Zhu, Qianqian Luo, Jun Liu, Jingtao Zhou, Xiaoyong Wang, Yuqiong Chen, Zhi Yu, Dejiang Ni

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.
