AI Article Synopsis

  • The study examined how replacing NaCl with KCl affects small molecular metabolites and the sensory quality of Xuanwei ham.
  • Thirty hams were divided into five treatment groups with varying NaCl and KCl ratios, revealing that increasing KCl led to higher moisture content and the release of flavor-enhancing metabolites.
  • Results indicated that treatments with 70% NaCl + 30% KCl and 60% NaCl + 40% KCl successfully reduced NaCl levels while still maintaining good taste and acceptability.

Article Abstract

The study was to understand the effect of the partial substitution of NaCl by KCl on small molecular metabolites and sensory quality of Xuanwei ham. Thirty green hams were randomly divided into five treatments, and salted with 100% NaCl (I), 70% NaCl+30% KCl (II), 60% NaCl+40% KCl (III), 50% NaCl+50% KCl (IV) and 40% NaCl+60% KCl (V), respectively. With the increase of KCl substitution, the moisture content of Xuanwei ham increased. Non-targeted ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-Q-Exactive-MS) was used to study the effect of partial substitution of NaCl by KCl, and twenty-eight metabolites were identified as markers of small molecular metabolites in the different treatments. KCl substitution promoted the release of tryptophan, histidine, citrulline, lysine, creatine and oleic acid, which contributed to improve the flavor and taste of ham. Therefore, the treatment II and III could reduce the NaCl content of Xuanwei ham by 30% and 40%, and maintained a better sensory acceptability.

To examine flavor variations in Xuanwei ham due to different cooking methods, we selected one-year cured Xuanwei ham and applied four techniques: dry frying (DF), baking (BA), steaming (ST), and boiling (BO). Organoleptic evaluation revealed ST received the highest overall sensory score. High-performance liquid chromatography (HPLC) revealed that the total nucleotide content was significantly different ( < 0.

An ethanol/(NH)SO biphasic (aqueous two-phase) system was designed to effectively separate antioxidant peptides from Xuanwei ham, and its potential to prevent ultraviolet A-induced damage to skin cells was explored. Optimization via single factor experiments and response surface methodology revealed that under 20 % ethanol aqueous solution (w/w), 25.5 % (NH)SO aqueous solution (w/w), and pH 8.

The aim of this study was to investigate the effects and mechanism of in vitro protein digestive products of Xuanwei ham with different ripening periods on cholesterol metabolism and hypercholesterolemia. The results showed that compared with other gastrointestinal digestion (GID) groups, the GID group of Xuanwei ham with 3-year ripening period (XWH3-GID) inhibited the expression of Niemann-Pick C1-like 1 (NPC1L1) and acetyl-CoA acetyltransferase 2 (ACAT2) through hepatocyte nuclear factor 1-alpha (HNF-1α), which in turn effectively inhibited cholesterol absorption in Caco-2 cell monolayers. Following absorption by Caco-2 cell monolayers, the XWH3-GID group suppressed the expression and secretion of proprotein convertase subtilisin/kexin type 9 (PCSK9) via HNF-1α, which enhanced the protein expression and fluorescence intensity of low density lipoprotein receptor (LDLR) on the HepG2 cell membrane, and thus promoted the uptake of low density lipoprotein (LDL).
