Article Abstract
This study demonstrates a new extraction method for determination of aflatoxins (AFs) in food samples by a GO-SiO/ZnO/FeO nanocomposite as new and effective sorbent. The nanocomposite structure was confirmed by FT-IR, XRD, EDX, FE-SEM, TEM, and mapping techniques. Optimization of the extraction process was conducted by investigating pH, adsorbent amount, sample volume, and solvent volume using central composite design (CCD). The method showed good linearity for AFs B, B, G, and G within specified ranges. Detection and quantification limits were 0.06-0.53 and 0.20-1.62 ng mL, respectively. The high performance liquid chromatography with fluorescence detector assisted by solid phase extraction (SPE-HPLC-FLD) method was applied to food samples, achieving recoveries of 70.15-97.08 %. Accuracy was confirmed through recovery measurements in spiked samples, with ranges of 70.15-97.85 % in wheat, 70.01-91.97 % in chickpeas, and 71.29-93.92 % in white pepper. Reusability and cost-effectiveness suggest its potential for preconcentration and determination of AFs in food samples.

Background: Children in the United States have poor diet quality, increasing their risk for chronic disease burden later in life. Caregivers' feeding behaviors are a critical factor in shaping lifelong dietary habits. The Strong Families Start at Home/Familias Fuertes Comienzan en Casa (SFSH) was a 6-month, home-based, pilot randomized-controlled feasibility trial that aimed to improve the diet quality of 2-5-year-old children and promote positive parental feeding practices among a predominantly Hispanic/Latine sample.

Despite alarming rates of students' food insecurity in the US (41%), estimates may not be fully capturing experiences in university settings. Understanding students' food insecurity is a knowledge gap flagged amidst outstanding progress on food security measurement in household settings. This study investigated the domains shaping the experiences around food with implications for food insecurity among students.

Breastfeeding is essential for reducing infant morbidity and mortality, yet exclusive breastfeeding rates remain low, often because of insufficient milk production. The molecular causes of low milk production are not well understood. Fresh milk samples from 30 lactating individuals, classified by milk production levels across postpartum stages, were analyzed using genomic and microbiome techniques.
