食品风味是决定食品品质的关键指标,也是影响消费者购买意向的重要属性。传统的食品风味评价方法依赖于人工感官、智能感官、仪器分析等。仪器分析技术可以定性定量检测食品中特征风味物质,但无法展示食品的味觉和嗅觉等感官信息,不能实现综合评价食品风味品质;人工感官分析可靠性高,但易受主观性影响且再现性差;智能感官分析技术则基于人类感官仿生技术开发,将传感器阵列与数据处理单元以及模式识别系统结合,从而对食品风味进行检测、评价,具有快速检测、操作简便、精密度高、再现性好等优势,备受研究者青睐。本文在简要介绍了电子鼻、电子舌和电子眼等智能感官技术概况的基础上,综述了智能感官技术在食品风味品质评价、食品新鲜度检测、食品真实性鉴别、产地溯源检测及其他检测方面的研究现状,探究了智能感官技术结合仪器分析技术、数据分析方法的研究进展,并讨论了现有研究的局限性及未来研究发展方向,以期为智能感官分析技术在食品风味评价的应用及深入研究提供理论依据和数据支撑。 相似文献

Consumption of mycotoxin-contaminated agricultural and food products has caused adverse human health effects for many centuries. Although mycotoxin contamination of agricultural products still occurs, application of innovative agricultural practices, food processing, and handling techniques has greatly reduced consumer exposure to mycotoxins. This paper reviews recent developments and potential applications of machine vision systems in replacing current labor-intensive, time-consuming methods by providing a quick, accurate, and low-cost alternative for detecting microbial and fecal contaminants in fresh and processed foods. The basic principles and components of the machine vision system are also discussed. 相似文献

The application of the Texturometer to a variety of foods is discussed. Illustrative data are reported for puddings, whipped toppings, cold cereals, potato chips, bread at different stages of staling, frankfurters, French fried potatoes, chocolate, etc. A one-kernel technique for rice is described and correlations with sensory evaluation for specific products are discussed. It is emphasized that optimum conditions of testing must be established for each class of products to parallel the human being who alters the manner of manipulating food in the mouth depending on its textural characteristics. Instrument conditions found adequate for testing different foods are given. 相似文献

High-pressure CO2 (HPCD) is a pasteurization method that inactivates microorganism and enzymes through molecular effects of CO2 under pressures below 50 MPa without exposing foods to adverse effects of heat. Thermal pasteurization can impart undesirable changes on organoleptic and nutritional quality of the foods, which can reduce sensory perception and consumer acceptance of the foods. As a novel nonthermal processing technique, HPCD does avoid drawbacks such as loss of flavor, denaturation of nutrients, production of side toxic reactions, as well as changes in physical, mechanical, and optical properties of the food materials involved in the processing. This review gives a survey and analysis of recent publications regarding the effects of HPCD on the flavor, texture and color of processed foods, and possible mechanisms explaining HPCD technique on the flavor, texture, and color of the foods were discussed. 相似文献

SUMMARY— A technique is described for using certain of the special characteristics of a universal testing machine which permits small distances to be measured with precision. A number of foods were compressed to a standard force, and the deformations of the foods were then measured off the strip chart recorder which is an integral part of the machine. The high degree of precision is obtained by driving the chart at a speed which is an exact multiple of the speed of the compressing plate. Differences between the deformation characteristics of different foods are shown. The advantage of using a standard size and shape of test piece is discussed. A method is shown for overcoming the effect of small imperfections in shape of standard pieces. It is also shown that a small deforming force will usually give a better resolution between similar samples than does a large deforming force. 相似文献
