Aroma dramatically impacts the overall flavor profiles and consumer acceptance; therefore, it is necessary to conduct a comprehensive analysis of the aroma characteristics of apples. In this study, the aroma differences among four popular apple varieties (“Ruixue”, “Liangzhi”, “Crystal Fuji,” and “Guifei”) were compared using two extraction methods (headspace-solid phase microextraction, and solvent-assisted flavor evaporation) coupled with gas chromatography–mass spectrometry–olfactometry (GC–MS–O) and two-dimensional gas chromatography-quadrupole mass spectrometry (GC × GC-qMS). A total of 82 odorants were identified via GC–MS–O, and 143 volatiles were identified by GC× GC-qMS. Among them, 41 key aroma-active compounds (butanal, ethyl acetate, 3-methylbutanal, methyl butanoate, 2-methylpropyl acetate, ethyl 2-methylbutanoate, ethyl 3-methylbutanoate, butyl acetate, hexanal, 2-methylbutyl acetate, 1-butanol, 2-methylpropyl butanoate, 3-methylbutyl acetate, (E)-2-hexenal, butyl butanoate, butyl 2-methylbutanoate, hexyl acetate, hexyl butanoate, hexyl, 2-methylbutanoate, 1-octen-3-ol, 3-methylthiopropanol, 1,3-octanediol, linalyl acetate, and so on) with high odor activity values (OAVs) and AI value (odor activity values ≥1 or aroma intensity ≥3) were identified. Partial least-squares-discriminant analysis showed that Ruixue exhibited a high “fruity” note, Guifei and Crystal Fuji had the greatest “wood,” “floral,” and “sweet” notes, while Liangzhi presented a significant “green” note. This study provided flavor chemistry support for the apple quality control and production.

In a world that is becoming increasingly concerned with health, safety, and the sustainability of food supply chains, the control and assurance of food quality have become of utmost importance. This review examines the application and potential of electrochemical sensors in the dynamic field of food science to meet these expanding demands. The article introduces electrochemical sensors and describes their operational mechanics and the components contributing to their function. A summary of the most prevalent electrochemical methods outlines the diverse food analysis techniques available. The review shifts to discussing the food science applications of these sensors, highlighting their crucial role in detecting compounds in food samples like meat, fish, juice, and milk for contemporary quality control. This paper showcases electrochemical sensors’ utility in food analysis, underscoring their significance as powerful, efficient tools for maintaining food safety and how they could transform our approach to global food quality control and assurance.

Lobster mushrooms, a type of wild edible mushroom that primarily grows in North America, have a distinctive aroma resembling seafood and are highly desired by fine dining establishments and food enthusiasts. Lobster mushrooms have a short collection season; therefore, they are usually dried for a year-round sale. Owing to their rising popularity, lobster mushrooms have become one of the most expensive mushroom species in the dried mushroom market. Herein, 35 odorants were identified from dried lobster mushrooms using solvent assisted flavor evaporation (SAFE) and aroma extract dilution analysis (AEDA). Fourteen odorants were quantitated using stable isotope dilution assays (SIDA), and their odor activity values (OAVs) were calculated. Eleven of the quantitated odorants exhibited OAVs of ≥1. Some notable odorants with relatively high OAVs included 2-acetyl-1-pyrroline (OAV 730), γ-nonalactone (OAV 410), 1-octen-3-one (OAV 180), and sotolon (OAV 170). The organohalogen molecule 2,6-dichlorophenol was determined to be key to the seafood aroma character of the mushrooms. An aroma simulation model formulated based on the quantitation data closely matched the aroma profile of the dried mushrooms. This study lays the groundwork for future studies aimed at understanding the effect of processing on lobster mushroom aroma chemistry and the biotechnological production of natural seafood flavors.
