Development of an analytical method for estimation of neotame in cake and ice cream

A homogeneous binary matrix assisted laser desorption/ionization time-of-flight mass spectrometry assay for determination of artificial sweeteners in beverages

Artificial sweeteners have been widely used as additives in various beverages. Due to the safety risks associated with artificial sweeteners, it is essential to develop a simple, rapid, and high-throughput method for the analysis of artificial sweeteners. Here, we report a homogeneous binary matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) assay for the simultaneous analysis of sweeteners including aspartame (ASP), neotame (NEO), and advantame (ADV) with a simple dilution step. The combination of nanodiamonds with 2,5-dihydroxybenzoic acid effectively improved the signal response of sweeteners, decreased the background noise, and improved the "spot-to-spot" repeatability. After the optimization, the method exhibits low limits of detection (ASP: 20 nΜ; NEO: 10 nΜ; ADV: 5 nΜ), good linearity (r > 0.995), satisfactory accuracy (96.2-103.0%), and lower RSDs (1.5-5.8%). Finally, the target sweeteners in 17 soft beverages were successfully determined with this method, showing the potential for the routine analysis of artificial sweeteners.

Deciphering the multifaceted effects of artificial sweeteners on body health and metabolic functions: a comprehensive review and future perspectives

As the rates of chronic diseases such as obesity and diabetes rise worldwide, there is a growing demand for low-calorie or no-calorie sweeteners to reduce sugar intake without sacrificing the sweetness of foods and beverages. Artificial sweeteners have become indispensable as substitutes for sugar due to their high sweetening power and low impact on blood sugar levels and are used in a variety of low-calorie foods and beverages. Although artificial sweeteners offer an alternative for reducing sugar intake while maintaining sweetness, research into their long-term health effects, particularly at high doses, is ongoing, further scientific research and regulatory review are needed to clarify these potential health risks. This article reviews the latest research on the health effects of artificial sweeteners, based on recent studies, introduces the classification, performance, and safety standards for artificial sweeteners, analyses their potential harms to the nervous, immune, and circulatory systems, reproductive system, as well as their effects on gut microbiota, liver function, cancer, diabetes, and obesity. In addition, consumer perceptions of artificial sweeteners and future research directions are discussed, providing insights into current research controversies and knowledge gaps, as well as the health research and market application of artificial sweeteners.

Prebiotics play a pivotal role in fostering probiotics, essential contributors to the creation and maintenance of a conducive environment for beneficial microbiota within the human gut. To qualify as a prebiotic, a substance must demonstrate resilience to stomach enzymes, acidic pH levels, and intestinal bacteria, remaining unabsorbed in the digestive system while remaining accessible to gut microflora. The integration of prebiotics and probiotics into our daily diet establishes a cornerstone for optimal health, a priority for health-conscious consumers emphasizing nutrition that supports a balanced gut flora. Prebiotics offer diverse biological functions in humans, exhibiting antiobesity, antimicrobial, anticancer, anti-inflammatory, antidiabetic, and cholesterol-lowering properties, along with preventing digestive disorders. Numerous dietary fibers possessing prebiotic attributes are inadvertently present in our diets, emphasizing the broader significance of prebiotics. It is crucial to recognize that, while all dietary fibers are prebiotics, not all prebiotics fall under the category of dietary fibers. The versatile applications of prebiotics extend across various industries, such as dairy, bakery, beverages, cosmetics, pharmaceuticals, and other food products. This comprehensive review provides insights into different prebiotics, encompassing their sources, chemical compositions, and applications within the food industry.

Determination of neotame in various foods by high-performance liquid chromatography coupled with ultraviolet and mass spectrometric detection

A new analytical technique involving protein precipitation, heating, lipid degreasing, and SPE procedures combined with HPLC-UV and HPLC-MS/MS has been developed for the determination of neotame in a variety of food samples. This method is applicable for high-protein, high-lipid, or gum-based solid samples. The limit of detection of the HPLC-UV method was 0.5 μg/mL, while that of the HPLC-MS/MS method was 3.3 ng/mL. The spiked recoveries of neotame in 73 kinds of foods were in the range of 81.1-107.2 % with UV detection. The spiked recoveries obtained by HPLC-MS/MS in 14 kinds of foods ranged from 81.6 % to 105.8 %. This technique was successfully used to determine the contents of neotame in two positive samples, indicating its applicability in food analysis.
