选取市面上常见的椒麻风味休闲食品为研究对象,对其麻感物质含量、麻度及其关联性进行了分析。分别采用高效液相色谱法和15 cm线性标度法对食品中主要酰胺类物质含量以及感官椒麻感强度进行了测定,分析了食品中主要物质成分与麻度之间的相关性,进一步利用Stevens函数解析了麻感风味物质含量与感官椒麻感强度的关联性。研究结果表明,市面上常见的椒麻休闲食品的麻感物质含量与椒麻感强度均存在显著差异,麻度主要分布在“微麻”到“麻”强度范围内。食品成分对幂函数参数和麻感响应规律存在显著影响,酰胺物质含量是影响麻度感知的最主要因素。构建了不同类型椒麻休闲食品体系下椒麻感官强度与物理量之间的Stevens函数模型,解析了食品成分对函数参数的影响。该研究结果为不同麻度的休闲食品的质量控制以及椒麻风味休闲食品的开发等提供了参考依据。 相似文献

黄酒是我国传统的低度发酵酒,因其具有营养丰富、口感醇厚等特点而深受大众喜爱。受人们饮食习惯与地方物产的影响,各地黄酒风味各异,且风味物质成分复杂,因此对黄酒风味物质的探索成为当前重点研究方向之一。随着仪器的更新换代、检测技术的飞速发展以及风味研究理论的逐步深入,关于黄酒风味的研究从最初简单的风味物质解析到感官评定的辅助分析与鉴定,再到风味组学研究的逐步建立,对黄酒风味物质的研究逐步变得系统而严谨。随着人们对食品安全的关注和对食品品质的严格要求,黄酒中有害异味物质的研究也备受关注。如何调控或清除黄酒中有害异味物质也已成为新的研究热点。本文从近年来学者对黄酒的研究入手,对黄酒风味物质的区域分布、种类、含量、提取、检测、发酵工艺及对风味物质的影响因素,黄酒中异味物质及危害等进行了文献综述。此综述可为黄酒风味物质的进一步研究、黄酒行业酒类品质提升提供文献参考。 相似文献

Pasteurized pineapple juice was concentrated by osmotic evaporation to produce a 51 d?Brix concentrate that was reconstituted to single strength juice for evaluation. Headspace gas chromatography (HSGC) showed that the concentrate retained an average of 62% of the volatile components present in the initial juice. A sensory panel preferred initial juice over reconstituted concentrate, and noted a decrease in desirable flavor top notes as well as development of some processed flavor in the concentrate. Similar HSGC analysis of four other commercial juice samples showed a wide range of quantitative values for volatile components, with the initial juice being similar to the weakest of these commercial juices. Analysis of concentrated juice extracts permitted identification of additional less‐volatile components not monitored directly by HSGC of the juice. Relatively low levels of these components were also present in the initial juice. Although this nonthermally produced concentrate retains more volatile components than when traditional thermal processing methods are used, addition of aqueous aroma to the concentrate may be required for satisfactory flavor. 相似文献

A full evaporation headspace gas chromatographic (HSGC) method is described for rapid determination of ethanol in soy sauce. The results demonstrated that a near-complete mass transfer of ethanol in the soy sauce sample to the vapor phase (headspace) was achieved within 2 min at 105 °C when a very small (≤40 μL) sample was added to a 20-mL headspace sample vial. The ethanol in the vapor phase was then determined by HSGC using a flame ionization detector. The results showed that the method has an excellent measurement precision (relative standard deviation <0.41 %) and accuracy (recovery?=?99.85?±?1.85 %) for ethanol quantification in soy sauce samples. The method requires no sample pretreatment, so it is a simple, rapid, and sensitive method for the accurate quantification of ethanol content in soy sauce and suitable for applications in food industry. 相似文献

For flavor perception to occur, the chemicals responsible for flavor perception must be released from the food matrix and transported to the flavor receptors in the mouth and nose. The overall process is governed by the properties of the flavor compounds, the nature of the food matrix and the physiological conditions of the mouth, nose and throat during consumption of the food. These factors combine to determine the concentrations and rate at which the flavor chemicals reach the receptors, thus creating the characteristic flavor profile of a food. Physicochemical factors like partitioning, interfacial mass transport and diffusion are the typical mechanisms governing flavor release. Although the theory behind these factors is well understood, applying them to the situation in‐mouth during eating is difficult. This is because key parameters like surface area and flavor concentrations in the gas and liquid phases change rapidly with time as a result of the physiological processes occurring during eating. Furthermore, individuals vary in their rate of breathing, swallowing and salivation, which affects the transport of flavors from the saliva phase to receptors on the tongue and in the nose. This review covers all aspects of flavor release from food matrices and the subsequent delivery of flavor to the olfactory and gustatory receptors. 相似文献

ABSTRACT To obtain useful and meaningful information on the contributions of rates of flavor migration and kinetics of degradation under various conditions, the goal of this study was to develop an apparatus for on-line measurement of flavor concentration, to formulate a thermally stable flavor-dough system and to accomplish isothermal heating. Methodology for measuring on-line flavor concentration in effluent gas from a closed vessel is discussed in this paper. Performance of the on-line apparatus for measuring flavor concentration with a cold-trap on-line sampling method was verified by conducting a series of recovery and retention experiments on 4 flavor compounds. Good quantitative recovery data were obtained. 相似文献
