In China, the rate of spicy food consumption is rising, and chili pepper is among the most popular spicy foods consumed nationwide. According to the 'cued overeating' model, visual and olfactory cues of food can lead to changes in physiological responses and increase the likelihood and amount of food intake. However, no studies have explored the role of spicy food cues in cue reactivity among spicy food cravers. The exploratory study aimed to investigate cue-induced physiological responses, subjective cravings, eating behaviors and their associations in spicy food cravers. A group of spicy cravers (n = 59) and a group of age- and sex-matched non-cravers (n = 60) were exposed to food cues that contained or did not contain chili, during which physiological responses and food consumption were measured. The results revealed that spicy food cravers showed increased salivation and heart rate in response to food cues that contained chili compared to cues without chili and consumed significantly more chili oil after chili exposure. For cravers, heart rate during chili exposure was positively correlated with changes in subjective spicy food craving, and increases in subjective spicy food craving during chili exposure positively predicted subsequent chili oil consumption. The current exploratory study confirms the 'cued overeating' model and extends previous findings on food cravings, showing that even though chili peppers can elicit aversive oral burns and pain, they share the same physiological mechanism underlying cue reactivity as other kinds of cravings.

Baijiu aged in Jiuhai container will produce a special Jiuhai-aroma, which has not been fully studied. In this study, check-all-that-apply method and quantitative descriptive analysis were used to characterize Jiuhai-aroma, and it was found that the aroma characteristics of herbs, spicy, cut hay and woody were prominent in Baijiu aged in Jiuhai container. According to the results of GC-O and quantification, 71 odorants were identified in Jiuhai sample.

Garlic and chili are widely used as food flavoring agents in food cooking, therefore might be accumulated in large amounts in food waste (FW). The effects of garlic and chili on the dissolution, hydrolysis, acidification and methanation in an anaerobic co-digestion system were investigated during the combined co-digestion of FW and excess sludge (ES). Additionally, the transformation of phosphorus form and microbial metabolism changes during the process were analyzed.

The levels of capsaicin (CAP) and hydroxy-α-sanshool (α-SOH) are crucial for evaluating the spiciness and numbing sensation in spicy hotpot seasoning. Although liquid chromatography can accurately measure these compounds, the method is invasive. This study aimed to utilize hyperspectral imaging (HSI) combined with machine learning for the nondestructive detection of CAP and α-SOH in hotpot seasoning.
