The density of unripe kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson cv. Hayward) early in storage was investigated as a means of determining the current fruit dry matter (DM) and total sugar-plus-starch concentrations, and of predicting DM and soluble solid concentrations later when the fruit had ripened. To investigate the robustness of the density relationships with DM...

Every year tons of fruits are processed in agro and food processing industry. The quality of the fruit plays a vital and is determined by shape, color and size. Manual sorting is one method to sort the fruits that is tedious and takes more time to process. To avoid the above difficulties, automatic sorting and grading can be done using machine vision system. Machine vision methods provide autom...

Date grading is an important process for producers and affects the fruit quality evaluation and export market. However, the high costs, low speed and variation associated with manual sorting have been forcing the post harvest industry to apply mechanization and automation in sorting operations. As a step toward mechanized grading, in this research Mamdani fuzzy inference system was applied as a...

The study aimed on evaluating the feasibility of NIRS to predict sweetness and acidity of intact mango fruit in form of soluble solids content (SSC) and titratable acidity (TA) through calibration modeling. Diffuse reflectance spectra in NIR wavelength range of 1000 – 2500 nm were acquired for a total of 58 mango samples. PCR and PLSR were used to develop SCC or TA prediction models respectivel...

introduction: nowadays, due to mechanization of life, consumers need of food which they spent little time for preparation, so fresh cut industry is growing rapidly in the world. these products had strong growth since 1940, and in 2013, most sales of fresh cut fruit related to apples, against 21.8 percent. minimal processing operations include grading, washing, sorting, slicing, chopping and the...

Mealiness degrades the quality of apples and plays an important role in fruit market. Therefore, the use of reliable and rapid sensing techniques for nondestructive measurement and sorting of fruits is necessary. In this study, the potential of acoustic signals of rolling apples on an inclined plate as a new technique for nondestructive detection of Red Delicious apple mealiness was investigate...

The development of science and technology, and especially of information technology, has made available many non-destructive methods for analysis of materials, which can also be applied to fruits. The fruit industry needs non-destructive techniques for on-line sorting and certifying high quality fruit. Electronic noses, acoustic methods and optical methods like near infrared spectroscopy are me...

Rapid ripeness assessment of fruit after harvest is important to reduce post-harvest losses by sorting according the duration until they become ready eat. However, there has been little research on non-destructive estimation and ripening speed avocado fruit. Unlike previous methods, which classify into a few categories (e.g., unripe ripe) or indirectly estimate from its firmness, we developed m...
