描述

一般說明

丙酸（PA）是一种天然羧酸，它在纯态下是一种无色的腐蚀性液体，具有难闻的气味。它可与水混溶。工业上以羰基镍作为催化剂，通过乙烯的加氢羧化作用制备丙酸。已有研究发现PA可减少食物摄入量、降低血浆和肝脏的脂肪酸含量、改善组织胰岛素敏感性并发挥免疫抑制作用。丙酸是一种出色的原材料，因为它稳定、廉价且安全，甚至可以用作食品添加剂。

應用

• Distribution Characteristics of Low-Molecular-Weight Organic Acids in Reclaimed Soil Filled with Fly Ash: A Study.: This research investigates the presence and distribution of propionic acid among other organic acids in reclaimed soils treated with fly ash. The study provides insights into the environmental impact and potential remediation strategies for soils contaminated with industrial by-products (Zheng et al., 2024).


• Effects of Black Soldier Fly (Hermetia illucens L., BSF) Larvae Addition on In Vitro Fermentation Parameters of Goat Diets.: This study examines how the addition of black soldier fly larvae affects the fermentation process of goat diets, including the production of propionic acid. The findings suggest potential benefits for improving animal nutrition and gut health (Lu et al., 2024).


• NMR Spectroscopy in Diagnosis and Monitoring of Methylmalonic and Propionic Acidemias.: This review highlights the use of NMR spectroscopy to diagnose and monitor methylmalonic and propionic acidemias, providing a non-invasive method for tracking these metabolic disorders. The study underscores the clinical significance of propionic acid in metabolic research (Deleanu & Nicolescu, 2024).


• The New Buffer Salt-Protected Sodium Butyrate Promotes Growth Performance by Improving Intestinal Histomorphology, Barrier Function, Antioxidative Capacity, and Microbiota Community of Broilers.: This study explores how propionic acid, along with sodium butyrate, improves the growth performance and gut health of broilers. The research demonstrates the beneficial effects of these acids on poultry farming (Melaku et al., 2024).


• Prevotella enterotype associates with diets supporting acidic faecal pH and production of propionic acid by microbiota.: This study links the presence of the Prevotella enterotype in the gut microbiota to diets that promote the production of propionic acid, emphasizing the role of diet in modulating gut health and metabolic functions (Adamberg & Adamberg, 2024).
