Abstract
Benzoic acid naturally exists in a variety of plants and fermented foods, and jujube contains natural benzoic acid. This study scrutinises the content of benzoic acid in diverse jujube cultivars, and its modulation by variables such as harvest timing, product types, and drying techniques. The methodology encompasses tracking the progressive augmentation of benzoic acid throughout the maturation process of jujube, with the apex content being 144.4 mg kg−1 in the Junzao cultivar. It further investigates the substantial fluctuations in benzoic acid content in jujube powder under disparate processing conditions, with the zenith content observed in drum-dried jujube powder at 127.6 mg kg−1, and an unexpectedly elevated level of 66.2 mg kg−1 in freeze-dried jujube powder. As long as it is not consumed excessively, it will not cause harm to the human body. The conclusion drawn from this research posits can be employed to resolve consumer grievances, or as a benchmark for testing services for product quality control.
Abstract
This work used a carrageenan-based thrombosis model to determine the preventative effects of Lactobacillus plantarum YS1 (LPYS1) on thrombus. In thrombotic mice, LPYS1 improved the activated partial thromboplastin time (APTT), while decreasing the thrombin time (TT), prothrombin time (PT), and fibrinogen (FIB) content. In thrombotic mouse serum, LPYS1 decreased the levels of malondialdehyde (MDA), tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), nuclear factor kappa-B (NF-κB), and interleukin-1 beta (IL-1β), while also increasing the activities of superoxide dismutase (SOD) and catalase (CAT). Moreover, LPYS1 upregulated the mRNA expression levels of copper/zinc-SOD (Cu/Zn-SOD), manganese-SOD (Mn-SOD), and CAT in the colon tissues of thrombotic mice, while downregulating those of NF-κB p65, IL-6, TNF-α, and interferon-gamma (IFN-γ) mRNA. In tail vein vascular tissues, LPYS1 suppressed the mRNA expression levels of NF-κB p65, intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin. The abundances of both beneficial and pathogenic bacteria were altered by LPYS1. These findings show that LPYS1 has the capacity to protect mice from thrombosis, while also revealing some of the underlying mechanisms of this effect.
