Research has demonstrated that hemp leaves are viable as feed for ruminant livestock.

The objective of this study was to analyze the presence of cannabinoids within rumen fluid, blood plasma, adipose tissue, and feces of beef steers consuming hemp. The trial included two 14-d periods followed by a 45-d monitoring period. In period 1, five ruminally cannulated steers were fed <i>ad libitum</i> hay. In period 2, steers continued to consume hay and were also supplemented hemp leaves at 3.9 mg/kg body weight (BW) cannabidiolic acid (CBDA) mixed with alfalfa cubes. Cannabinoid accumulation, including cannabidiol (CBD) and delta-9 tetrahydrocannabinol (Δ⁹-THC), was measured in tissues at various timepoints. Hemp consumption resulted in prolonged accumulation of cannabinoids in beef cattle tissues - at least 96 h in blood and 6 weeks in adipose tissue.

During harvesting, processing and storage (damping and compression), mechanical damage to kernels inevitably creates fracture/breakage and thereafter mildew in the grain silo. One issue that the effect of breakage type and position on mildew under one dimensional (1D) loading was not fully understood up to date. In this paper, the effects of different fracture types and spatial positions on mold proliferation under compressive storage conditions were investigated. First, this study simulates the storage of grain piles under 1D load conditions using in total nine tests in three studies. The effect of breakage type and spatial position on mildew under different compression load were researched. The dry matter loss, grain temperature along with colony count were compared among different breakage type and positions of broken kernels. The results proved that as the moisture content increased, the compression of the pile was larger and the porosity was correspondingly lower, which in turn caused an increase in the temperature and the number of broken kernels. These factors were the main causes of mould in the pile. It is imperative that kernels exposed to the endosperm should be prioritized by screening if necessary, and attention should be paid to the center of the silo during ventilation, which can effectively reduce the mould in the pile. In conclusion, this study aims to understand the fungal contamination under varied kernel fractures and further help to reduce economic losses and improve the food safety after proper management.</p>","PeriodicalId":12295,"journal":{"name":"Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment","volume":" ","pages":"1-12"},"PeriodicalIF":2.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144101629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional analytical methods such as HPLC and ion exchange chromatography are commonly used to detect adulteration in whey protein supplements.

This study presents a rapid and reliable approach for verifying the authenticity of whey protein supplements using laser-induced breakdown spectroscopy (LIBS) and machine learning. Specifically, this approach is employed to identify 15 brands of whey protein concentration (WPC), quantify protein and carbohydrate concentrations, distinguish three types of adulterants, and predict the level of adulteration. The relationship between LIBS data and analyte labels is established using machine learning methods, including partial least squares regression (PLSR), partial least squares discriminant analysis (PLS-DA), and kernel extreme learning machine (K-ELM). The accuracy for identifying WPC brands was over 0.977, and the highest coefficient of determination (<i>R</i>²) for quantifying protein and carbohydrate contents was 0.984 and 0.978, respectively. In addition, different adulterants can be differentiated with accuracies exceeding 0.986, and the <i>R</i>² values for adulteration prediction are above 0.967 in most cases.

The methods employed, including Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray powder diffraction analysis (XRD), X-ray Photoelectron Spectroscopy (XPS), and Fourier Transform Infrared Spectroscopy (FT-IR), effectively showed the synthesis of LCys-Fe₃O₄ NPs. The proposed method was not only used for patulin removal; rather, it significantly enhanced the sensitivity of patulin measurement. The efficiency of patulin elimination was affected by many factors, including contact time (5-140 min), patulin initial concentration (50-150 µg/L), and amount of NPs (1-5 mg). The synthesized adsorbent achieved a removal efficiency of 98.6% for patulin adsorption at pH = 3.8. This was accomplished by employing 3 mg LCys-Fe₃O₄ NPs over a 100-min duration, resulting in a maximum adsorption capacity of 454 µg/g for the initial concentration of patulin 50 µg/L. This high removal efficiency can be attributed to active surface sites (-NH₂ and -COOH groups). The removal information obtained from an HPLC method, using the prepared adsorbent, exhibited a good fit with the Freundlich isotherm, indicating a multi-layer adsorption process on the adsorbent. The experimental findings were analyzed using an adsorption kinetic model, revealing that the adsorption kinetics of patulin onto LCys-Fe₃O₄ NPs conformed to the pseudo-second-order model.
