In recent years, there has been rapid growth in the availability of innovative, non-combustible products, including oral tobacco-derived nicotine (OTDN) products, heated tobacco products (HTPs), and electronic cigarettes (also referred to as e-vapor products; EVPs). Industry, academic, and government researchers are developing and validating analytical methods to extract, separate, identify, and quantitate a variety of analytes from these innovative tobacco products using a wide range of analytical techniques. These analytes include constituents such as nicotine, degradants and impurities, flavors, non-tobacco ingredients, HPHCs, and other currently unknown constituents. In this Special Issue, we received nine contributions that covered the latest analytical methods that have been developed and applied for the chemical characterization or exposure assessment to tobacco product constituents of innovative non-combustible products. This Special Issue is representative of the importance of analytical sciences research in characterizing innovative non-combustible products for guiding product design, determining relative product performance, ensuring consistency during the manufacturing process, informing toxicological risk assessment, and enabling regulatory reporting. The current advances in the development and applications of the analytical methods reported in this Special Issue can be used to inform the harm reduction potential of innovative non-combustible products for adult smokers.

Pesticides are used worldwide, and despite the fact that organic farming is increasing, they are still widely applied in different countries with pesticide regulations and monitoring programs. This Special Issue will cover the topic of the presence of pesticide residues in food, paying special attention to the use of modern analytical techniques based on chromatographic techniques coupled to mass spectrometry. Generic extraction methods are needed to allow the detection of pesticides with different physic-chemical properties, as well as different families of contaminants can be extracted simultaneously. Nevertheless, pluriresidue methods are still necessary for “orphan” compounds that cannot be included in multiresidue methods. Thus, in addition to targeted pesticides, the scope of this analysis can be increased and nowadays, metabolites are also detected, evaluating the degradation of pesticide residues in different food matrices.

Plants, including vegetables, are an essential element of the human diet, considering their dense nutritional content and bioactive content that could assist in boosting nutritional quality and food security. Plants are exhibiting a colossal rebound in the context of healthier lifestyles, especially as functional foods empowered with bioactive phytochemicals; they synthesize uncountable “ecochemicals” via secondary metabolism, which command medical and socioeconomic significance. Among these secondary metabolites, phenolic compounds are of prime interest and are largely present in medicinal plants, herbs, vegetables, and flowers. These metabolites are at the helm of the bitterness, color, and scent of plants, and are correlated to the beneficial health qualities expressed by the antioxidant capacity. The accretion of these health-promoting phytochemicals depends chiefly on the genetic material and the maturity stage at harvest, notwithstanding the main role that is played by preharvest factors, i.e., eustress, fertilization, irrigation, light, biostimulants, biofortification, and other agronomic practices. This Special Issue is a collection of 11 original research articles addressing the quality of seeds, microgreens, leafy vegetables, herbs, flowers, berries, fruits, and byproducts. Mainly preharvest factors were assessed regarding their effect on the qualitative aspects of the aforementioned plants.
