“…Moreover, industry demand increased for innovative tools: rapid with cost-effective for the evaluation and monitoring of citrus fruit quality. Therefore, several researches were focused on the application of new non-destructive methods in citrus fruit quality detection, including hyperspectral imaging (HSI), electronic noses (e-noses) techniques and nuclear magnetic resonance (NMR) [60][61][62].…”

Citrus is a fruit crop grown in different Mediterranean countries. Generally, harvested fruits are used for fresh consumption or are processed (mainly to produce juices). In this chapter, the authors discuss the state of art on citrus postharvest with a scientific approach, evaluating the current knowledge about the physiology and pathology of citrus fruits and the main causes of deterioration. In addition, the authors explain the main facilities for the cold storage of citrus fruit with particular reference to the rapid-cooling techniques and treatments needed prior to shipment of citrus fruits (refer shipment). In the last part of the chapter, the non-destructive methods for the quality evaluation are presented.

“…Present methods of carotenoids assay require its extraction from samples by hazardous organic solvents, are timeconsuming, require extensive sample preparation, tedious, hazardous and destructive (Rivera and Canela, 2012). Partial least square regression (PLSR) has been widely used for non-destructive food quality evaluation of agricultural products by NIR spectroscopy (Huang et al, 2014;Wang et al, 2015). PLSR offers an edge over Principal Components Regression (PCR) because the resulting spectral vectors are directly related to the constituents of interest.…”

Carotenoids analysis is complicated by their tendency to react with radical species, resulting in oxidative breakdown and isomerization during extraction. Hence, analysis methods should be rapid and avoid unnecessary exposure to high temperature, acids, and so on. The aim of this work to estimate carotenoid contents of processed tomato products non-destructively. The mean values obtained by visible and near-infrared Vis/NIR spectroscopy and by high performance liquid chromatography (HPLC) for eight carotenoid contents (ß-carotene, 5-cis lycopene, 13-cis lycopene, 9-cis lycopene, all-trans lycopene, zeaxanthin, lycoxanthin and total carotenoids) in four processed tomato products from five different brands were compared. The carotenoid contents were measured using HPLC, and these results were then used to develop partial least squares regression (PLSR) models to predict carotenoid components from Vis/NIR spectra of the same samples. A good correlation was found between HPLC measurements and the Vis/NIRs (590-790 nm) predictions for ß-carotene (RP2= 0.88), 9-cis lycopene (RP2= 0.86), total carotenoids (RP2= 0.84), 13-cis lycopene (RP2= 0.83), 5-cis lycopene (RP2=0.80), zeaxanthin (RP2= 0.80) to passable for all-trans lycopene (RP2= 0.70), but there was only a poor correlation (RP2= 0.20) for the lycoxanthin component. The overall results indicated that Vis/NIRs could be applied to assess carotenoid contents of different processed tomato products.

“…Despite the great amount of effort put into and many advancements in postharvest technology to prevent fungal infections and to extend shelf life [32,33], cosmetic defects such as bruising are unavoidable in the fresh-fruit market [34]. Such damage is associated with a reduction of the quality of fresh products, which leads to large product and financial losses [5].…”

Postharvest fruits are susceptible to damage which eventually results in large product and financial losses. While abundant studies have been conducted to objectively index the severity of such damage, how consumers subjectively assess the severity of damaged apples has been understudied. Previous studies have indicated that consumers’ aesthetic devaluation of product quality is reflected in estimated price. Thus, the current online questionnaire study was conducted to examine the effect of objectively indexed severity of damage on consumers’ subjective price estimations. Four hundred thirty-nine consumers of apples were asked to estimate the market price for apples in photographic images of 1 or 3 “Orin” (“Golden Delicious” × “Indo”) apples at 9 levels of severity of damage. A 2 (1- and 3-piece) × 9 (severity of damage) within ANCOVA with reference price as a covariate indicated significant two-way interaction between the number of apples and severity of damage on estimated price. Consequently, the 1- and 3-piece conditions were examined separately. The results of both analyses indicate a categorical rather than quantitative, continuous reduction in estimated price.
