A rapid, low-cost and simple technique has been developed for the determination of aflatoxin B1 (AFB1) in eggs and livers using high-performance liquid chromatography (HPLC) with UV detection. In this study, the presence of AFB1 was investigated in 150 eggs and 50 chicken livers from the local market of Tabriz, Iran. AFB1 was extracted with a mixture of acetonitrile:water (80:20) and cleaned up by dispersive liquid-liquid microextraction which is a very economical, fast and sensitive method. AFB1 was quantified by HPLC-UV without need for any complex derivatisation in samples to enhance the detection. The results showed that 72% of the liver and 58% of the egg samples were contaminated with AFB1 ranging from 0.30 to 16.36 µg kg (̶1). limit of detection and limit of quantification for AFB1 were 0.08 and 0.28 µg kg (̶ 1), respectively. The proposed method is suitable for fast analysing of AFB1 in egg and liver samples.

Cellulosic nanomaterials have significantly promoted the development of sensing devices, drug delivery, and bioreactor processes. Their synthetic flexibility makes them a prominent choice for immobilizing biomolecules or cells. In this work, we developed a practical and user-friendly approach to accessing cellulose nanoparticles (CNPs).

Conjoined twinning is a special case of monozygotic, monoamniotic twinning. Human conjoined twinning, and vertebrate conjoined twinning in general, is a very rare phenomenon. It has been suggested that the risk of conjoined twinning increases with some medication and upon assisted reproduction.

The objective of this study is to develop an HPLC-UV method for the cost-effective and quantitative determination of vitamin D3 in food, even in the presence of vitamin D2, with a specific focus on egg yolk. During method development, the performance of three stationary phases in resolving the peak of vitamin D2 from that of vitamin D3 was investigated. The physicochemical properties of these phases differed particularly in the extent of hydrophobicity and silanophilic activity, including a GraceSmart RP C18 column without silanol endcapping, a Robusta RP C18 column with silanol endcapping, and a Waters Xbridge RP C18 column with ethylene-bridged hybrid (BEH) particle technology.

Polychlorinated naphthalenes (PCNs), which are ubiquitous in the environment, are listed as persistent organic pollutants under the Stockholm Convention. Poultry can be exposed to PCNs via feed and breeding environments, leading to PCNs accumulation in eggs. However, information on PCNs in eggs from waterfowl raised in contaminated regions is scarce.

The detection and classification of damage to eggs within the egg industry are of paramount importance for the production of healthy eggs. This study focuses on the automatic identification of cracks and surface damage in chicken eggs using deep learning algorithms. The goal is to enhance egg quality control in the food industry by accurately identifying eggs with physical damage, such as cracks, fractures, or other surface defects, which could compromise their quality.
