The areca nut is one of the most important cash crops in the tropics and has substantial economic value. However, the research information about the edible quality of different areca nuts is still insufficient. This study compared the composition, texture characteristics and flavor release behaviors of four different areca nuts (AN1, AN2, AN3 and AN4) and two commercially dried areca nuts (CAN1 and CAN2). Results showed that AN1 had higher soluble fiber and lower lignin, which was the basis of its lower hardness. Meanwhile, the total soluble solid (TSS) of AN1 was the highest, which indicated that AN1 had a moister and more succulent mouthfeel. After the drying process, the lignification degree of AN1 was the lowest. Through textural analyses, the hardness of AN1 was relatively low compared to the other dried areca nuts. AN1, CAN1 and CAN2 had higher alkaline pectin content and viscosity, and better flavor retention, which indicated better edible quality. The present study revealed the differences of various areca nuts and provided vital information to further advance the study of areca nuts.

Effect of electron beam irradiation treatment on microstructure, physicochemical properties, and bioactive content of areca nut.
J Sci Food Agric

Background: Electron beam irradiation treatment is a novel technology that uses low-dose ionizing radiation for the treatment of crops or food to enhance their quality. This study investigated the effects of electron beam irradiation on the microstructure, physicochemical properties, and bioactive compounds of areca nuts.
Results: As the irradiation dose increased, the cellulose, hemicellulose, and lignin content in the areca nuts decreased significantly, whereas the polysaccharide and pectin content increased gradually.

The present study revealed that various non-dietary items like pan masala, chewing tobacco, betel nuts, and toothpaste may contribute to the fluoride burden of the human body. In this line, an attempt was made to analyze the fluoride content of non-dietary items collected from Panipat City of Haryana. The study depicts that intake of pan masala, chewing tobacco, betel nuts, and toothpaste expose the consumers to 21.

In this study, the structure of Areca nut polysaccharide (ANP) was characterized, and its effects on macrophage activation and the underlying molecular mechanisms were investigated. ANP was identified as a glucan with a molecular weight of 24.5 kDa, and its structure was analyzed using XRD, SEM, FT-IR, methylation, and NMR techniques.

Background: The addictive potential of areca nut (AN) and tobacco is well-documented, but their combined neurobiological effects in AN-containing tobacco products (ANTP) remain obscure. This study employed a three-stage in silico approach to investigate the potential targets and pathways associated with the addictive properties of AN alone and in ANTP.
Materials And Methods: Bioactive molecules were retrieved for AN and tobacco, followed by target prediction and pathway enrichment analysis.
Effects of postbiotics on fibrotic response in arecoline-induced oral fibrogenesis.

Article Synopsis
- Oral submucous fibrosis (OSF) is linked to Areca nut consumption and involves excessive collagen buildup, with postbiotics like PostBio GK4 being investigated as a potential treatment.
- The study tested GK4's effects on normal and fibrotic buccal mucosal fibroblasts (BMFs), measuring its influence on collagen contraction, cell migration, and healing properties.
- Results indicated that GK4 reduced the negative effects induced by Arecoline on BMFs and suppressed fibrosis-related signaling pathways, suggesting it could be a useful therapy for OSF with further research needed.
