“… Saad et al, (2016) used visible/near-infrared (VIS/NIR) spectroscopy to investigate the tomato fruit quality traits during storage. They reported that the PLSR calibration model with SSC had the highest coefficient of determination (R 2 ) = 0.91, RMSEP = 0.285, while R 2 for lycopene was the lowest (0.73).…”

Non-destructive methods have been widely recognized for evaluating fruit quality traits of many horticultural crops and food processing industry. Destructive (analytical) test, and non-destructive evaluation of the quality traits were investigated and compared for ‘Red Rose’ tomato ( Solanum lycopersicum L.) fruit grown under protected environment. Fresh tomato fruit at five distinctive maturity stages namely; breaker (BK), turning (TG), pink (PK), light-red (LR), and red (RD) were labeled and scanned using the handheld near infra-red (NIR) enhanced spectrometer at a wavelength range of 285–1200 nm. The labeled tomato samples were then measured analytically for flesh firmness, lycopene, β-carotene, total phenolic content (TPC) and total flavonoids content (TFC). The results revealed that quality traits could be estimated using NIR spectroscopy with a relatively high coefficient of determination (R 2 ): 0.834 for total phenolic content, 0.864 for lycopene, 0.790 for total flavonoid content, 0.708 for β-carotene; and 0.679 for flesh firmness. The accumulation of Lyco and β-Car rapidly increased in tomatoes harvested between the TG and the LR maturity stages. Harvesting tomatoes at BK maturity stage resulted in significantly higher flesh firmness than harvesting at the later maturity stages. Tomato fruits had the lowest TPC and TFC contents at the earliest maturity stage (BK), while they had intermediate TPC and TFC levels at LR and RD maturity stages. NIR spectroscopic measurements of fruit firmness and lipophilic antioxidants in tomato fruit at various maturity stages were partially in accordance with those estimated by destructive (analytical) methods. Based on these findings, we recommend using non-destructive NIR spectroscopy as an effective tool for predicting tomato fruit quality during harvest stage and postharvest processing.

“…To each sample, 25 milliliters(mls) of water was added. Each sample was titrated with 0.1 N NaOH to an end point of 8.1 (with phenolphthalein indicator) and the milliliters of NaOH used was recorded (Saad et al, 2014) . The titratable acidity was calculated using the following formula:…”

An experiment was conducted to evaluate the effect of different postharvest treatments on maintaining quality and shelf life of sweet orange from Feb-Apr 2019 under completely randomized (CRD) with four replications and five treatments (T1= Aloe vera gel @100%, T2= Paraffin wax @100%, T3= Corn Starch @4%, T4=Tragacanth Gum @4%, T1=Control i.e. untreated fruits) at ambient room condition (15.15±0.33ºC, 58.16±1.69% RH). The parameters recorded were Physiological loss in weight (PLW), total soluble solid(TSS), titratable acidity(TA), Shrinkage, Juice content, Marketability, Disease Incidence and Shelf life in every 5 days' interval till 40 th day. Minimum percentage of PLW was observed in the fruits treated with paraffin wax (5.83% in 40 th day) which was statistically at par with the findings of all other coated fruits. Corn starch showed minimum shrinkage (4.27%) which was statistically at par with Paraffin wax (100%) and tragacanth gum (4%). Wax treated fruits recorded the maximum juice recovery percentage (31.43%) whereas the minimum juice recovery percentage (27.81%) was observed in control fruits. The control fruits (untreated) showed the maximum TSS (15.03º brix) which was statistically at par with Aloe Vera and Corn starch. Higher acidity was found in the fruits treated with Aloe Vera (100%) (0.917) which was statistically par with corn starch (4%) and tragacanth gum (4%). The marketability value of tragacanth gum treated fruits was reported to be maximum (4.445). Minimum disease index (2.25) was observed in the fruits treated with tragacanth gum which was statistically at par with Aloe vera gel and corn starch treated fruits whereas postharvest life was found maximum (69 Days) in fruits treated with Aloe vera (100%) while it was only 46 in control fruits.

“…Rapid spectroscopy methods for the evaluation of carotenoids have been developed with the NIR technique, especially focused on lycopene (Oliveira, 2014;Saad et al, 2014). Rubio-Diaz et al (2010) were also successful in non-destructive measuring the carotenoid composition with infrared spectroscopy in tomatoes.…”

A b s t r a c t. A rapid non-destructive method for profiling tomato carotenoids was developed using NIR spectrometry. One hundred and twenty tomato samples were produced at the Experimental Farm of Szent István University in Gödöllő (Hungary). The sample preparation was based on homogenization. The mixed samples were scanned with a diode array Perten DA7200 NIR Analyzer (950-1650 nm) and analyzed by high performance liquid chromatography. The calibration was based on partial least squares regression with cross-validation. The performance of the final model was evaluated according to root mean square error of cross-validation. The results indicate that the main carotenoid components were accurately predicted. The correlation between the NIR measurement and the β-carotene content of tomatoes was adequately high [R 2 CV = 0.89; root mean square error of cross-validation = 0.174 µg g -1 ]. The NIR method was also performed for the determination of the all-trans lycopene content (R 2 CV = 0.75; root mean square error of cross-validation = 6.88 µg g -1 ). It can be concluded that the diode array NIR spectrometer has the potential to be used for the determination of the main carotenoids of tomatoes.K e y w o r d s: tomato, carotenoid composition, near-infrared spectroscopy, partial least squares regression INTRODUCTION
