Juice Quality Evaluation with Multisensor Systems-A Review

Area of Science:

• Analytical Chemistry
• Food Science
• Sensor Technology

Background:

• Electronic noses (e-noses) and electronic tongues (e-tongues) are advanced multisensory systems utilizing specialized sensors for rapid and precise analysis of volatile compounds (smells) and non-volatile compounds (flavors).
• These technologies are integral to the food industry for quality control, ingredient identification, contamination detection, and shelf-life assessment.
• Their application extends to diverse sectors, highlighting their versatility in analyzing complex chemical profiles.

Purpose of the Study:

• To provide a comprehensive review of e-nose and e-tongue applications across various industries.
• To specifically focus on the utilization of these multisensory systems within the fruit and vegetable juice industry.
• To analyze recent global research (last five years) on their use for assessing juice quality, taste, and aroma profiles.

Main Methods:

• Literature review and analysis of worldwide research published within the last five years.
• Examination of studies focusing on the application of e-nose and e-tongue technologies in the food and beverage sector, with a specific emphasis on fruit and vegetable juices.
• Inclusion of a characterization of e-nose and e-tongue devices, covering their origin, operational principles, types, benefits, drawbacks, challenges, and future prospects.

Main Results:

• E-noses and e-tongues demonstrate significant potential for objective and rapid quality assessment of fruit and vegetable juices.
• Research indicates successful application in differentiating juice varieties, detecting adulteration, and monitoring sensory attributes.
• The review synthesizes findings on the performance, limitations, and emerging trends of these technologies in juice analysis.

Conclusions:

• E-nose and e-tongue technologies are valuable tools for enhancing quality control and analytical capabilities in the fruit and vegetable juice industry.
• Further research and development are needed to overcome current challenges and expand the scope of their applications.
• These multisensory systems offer promising perspectives for innovation and efficiency in food analysis beyond the juice sector.
