Article Abstract
Fiber optic surface plasmon resonance (SPR) sensor utilizing silver (Ag) and Ag-graphene oxide (GO) is designed and developed for the detection of adulteration of glucose and fructose in pure honey. The concentration range of the two adulterants in pure honey is varied from 4% to 20% with a step change of 4%. The experiments were performed with two different fiber optic probes viz. Probe 1 and Probe 2. Probe 1 is fabricated by coating 50 nm Ag film on unclad optical fiber portion and Probe 2 is fabricated by modifying Ag film with GO for sensitivity improvement. The study confirms that using GO modified fiber optic probe, the sensitivity is enhanced to 24% and 37% for glucose and fructose adulterated honey samples respectively. The technique presented in this study is easy, rapid, label free and shows high prospective for the detection of adulterants in pure honey.

This study utilized the synergistic effectiveness of chia seed mucilage and iron (III)-natural phenolic nanoparticles as biosorbents for the first time in the dispersive solid-phase extraction (DSPE) of oxytetracycline, tetracycline, chlortetracycline, and doxycycline followed by HPLC-UV quantification. An in-situ iron (III)-natural phenolic solid adsorbent was created using natural phenolics found in the copper pod tree bark. An ultrasonic-assisted extraction was performed to enhance the extraction efficiency of DSPE-based biosorbents.

The contamination of sulfonamide in food and environmental applications has highlighted a great necessity to develop amphoteric adsorbents for their simultaneous extraction and determination. The combination of cetyltrimethylammonium bromide with alginate-MS, which has a wide surface area, high porosity, high water absorption, and biodegradability, as an adsorbent for the determination of sulfonamide residues by ultra-high performance liquid chromatography-photodiode array detector (UHPLC-PDA) was proposed. Convenient conditions led to the facile synthesis of the sorbent.

Food fraud raises significant concerns to consumer health and economic integrity, with the adulteration of honey by sugary syrups representing one of the most prevalent forms of economically motivated adulteration. This study presents a novel framework that combines data from multiple analytical techniques with specialized deep learning models (convolutional neural networks), integrated via meta-learning, in order to differentiate between pure honey and samples adulterated with sugar cane molasses, glucose syrup, or caramel-flavored ice cream topping. Unlike traditional chemometric methods, this approach expands the input feature space, leading to enhanced predictive performance.

Background: Honey has been successfully used in wound care and cosmetics because of its effective biological properties, including antibacterial, antioxidant, and anti-inflammatory activities. Polyphenols, particularly phenolic acids, are key honey components responsible for these beneficial effects. In recent years, there has been a growing demand for natural, ecologically friendly, and biodegradable products in the modern cosmetics and wound care market.
