Evaluation on home storage performance of table grape based on sensory quality and consumers’ satisfaction

Abstract

With continuous rise of table grapes consumption and increased public awareness of food safety, the quality control of grapes in storage after purchase is not sufficiently examined. Home storage constitutes the last and important stage in grape supply chain. Literature review shows that few researches on grape quality focus on the home storage stage compared with numerous researches reported on the quality control during postharvest and transportation process. This paper reports the performance evaluation of grape quality at home storage and consumers' satisfaction using integrated sensory evaluations. The internal attributes, including Texture, Taste and Odor of the table grapes and the appearance indices, Color and Cleanliness are examined. Key results show that during home storage, all the internal attributes decrease rapidly as time goes on, and cleanliness and color appear to be deteriorating in a lower speed. A comprehensive quality index was created to measure the quality of table grape which has high correlation with the Overall acceptability perceived by consumers.

Postharvest Quality Monitoring and Variance Analysis of Peach and Nectarine Cold Chain with Multi-Sensors Technology

“…During the transport and in subsequent cold storage, real-time monitoring of temperature, relative humidity, CO 2 , and GPS for experimental fruit was performed by WSN. Firmness, weight loss, total soluble solids (TSS), titratable acid (TA), and sensory properties are important factors of fruit quality and they play significant roles in consumer preferences, thus having a prominent role in fruit quality assessment during storage [36][37][38]. Weight loss (WL), SSC, and firmness are the easiest quality indicator among these quality indicators to measure using a handheld penetrometer during the cold chain logistics, while the others need special instruments or environments.…”

Assessment of main factor causing sensory quality defects in chicken seasoning during storage

“…Consumer choice of food may be determined by its quality, especially its sensory quality . Sensory evaluation has been used to evaluate the sensory quality of foods . This approach can classify chicken seasonings based on their difference in aroma and give an overall profile of their sensory character .…”
