The Effect of Different Types of Coating and Packaging on the Physical Properties of Persimmon Fruit under Load

Sajad Jafarzadeh; Mohsen Azadbakht; Faryal Varasteh; Mohammad Vahedi Torshizi

Volume 19, Issue 3 , July and August 2023, , Pages 1-14


  Since persimmon is a pressure-sensitive fruit and it is difficult to store this fruit in warehouses, in this research, an attempt has been made to examine the parameters affecting the reduction of changes in its physical properties. The samples were loaded at 150 and 250 N, three types of foam container ...  Read More

Effects of various coatings and packing materials on persimmon fruit color indexes during quasi-static loading

Sajad Jafarzadeh; Mohsen Azadbakht; Faryal Varasteh; Mohammad Vahedi Torshizi

Volume 18, Issue 3 , July and August 2022, , Pages 1-14


  Nowadays, the quality of processed fruits or products is defined by a set of physical and chemical properties. In this study, due to the sensitivity of persimmon fruit to pressure, the parameters affecting the color changes of this fruit after pressure have been investigated. Three different coatings ...  Read More

Evaluating the effects of blanching and microwave pre-treatments on variations in some selected physiological factors of artichoke leaves in fluidized bed dryer

Mohsen Azadbakht; Bahareh Eshaghi; Ali Motevali; Azim Ghasemnezhad

Volume 17, Issue 6 , January and February 2022, , Pages 73-83


  In this study, temperatures (40, 50, and 60°C), air velocity (3, 5, and 7 m/s) and pre-treatment (without pre-treatment, blanching, and microwave) were used as variables for investigation of antioxidant activity of dried artichoke leaves. The results revealed that variations in temperature and air ...  Read More

Energy and exergy analyses in microwave drying of orange slices

Mohsen Azadbakht; Mohammad Vahedi Torshizi; Fatemeh Noshad; Arash Rokhbin

Volume 16, Issue 3 , July and August 2020, , Pages 1-13


  The orange samples were cut into slices with a thickness of 4 mm and treated with ohmic method for 3, 5, and 7 min as ohmic pre-treatment in three voltages 30, 50 and 70 V. Then, they were dried in three replicates using a microwave dryer and at three powers of 90, 360, and 900 W. The statistical analysis ...  Read More

Predicting the physiological characteristic changes in pears subjected to external loads using Artificial Neural Network (ANN)-Part 1: Static loading

Mohsen Azadbakht; Mohammad Vahedi Torshizi; Mohammad Javad Mahmoodi

Volume 16, Issue 3 , July and August 2020, , Pages 63-85


  This research was aimed to study the effects of loading force and storage period on the physiological characteristic of pears. In this experiment, the pears were subjected to quasi-static loading (wide-edge and thin-edge) and different storage periods (5, 10 and 15 days). The amounts of the fruits’ ...  Read More

Study on Firmness and texture changes of pear fruit when loading different forces and stored at different periods using artificial neural network

Mohammad Vahedi Torshizi; Mohsen Azadbakht

Volume 15, Issue 6 , January and February 2020, , Pages 113-132


  This study evaluated the effect of different dynamic and static loadings and different storage periods on the firmness of pear fruit. Pear fruit was first segregated into three groups of 27 pear in order to undergo three loadings: static thin-edge compression loading, static wide-edge compression loading ...  Read More

Determination of the relationship between volume and weight of pear fruit with bruise due to impact load loading using non-destructive CT scan

Mohsen Azadbakht; Mohammad Javad Mahmoodi; Mohammad Vahedi Torshizi

Volume 15, Issue 2 , May and June 2019, , Pages 341-353


  Introduction: The study of relationship between physical properties such as mass and volume and other physical properties, such as geometric dimensions, has been the subject of numerous studies by researchers. The fruit size, shape and mass are important in sorting and measuring fruits, and it determines ...  Read More

Effect of pulsation period and microwave power on paddy drying

Hassan Jafari; Davood Kalantari; Mohsen Azadbakht

Volume 13, Issue 6 , January and February 2018, , Pages 92-104


  In this study, the influence of different microwave powers (90, 270, and 450 W) and pulsation periods, i.e., On/Off times (30/60 and 30/120 ss-1) on drying rate and seed breakage of “Nemat” and “Hashemi” paddy varieties” was investigated. According to the results, the Midilli ...  Read More
