in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...

to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...

Wine was a fermented drink made of grapes extract. However, wine could be from other fruits that contain glucose, such as snake fruit. Making snack fruit an alternative to overcome the abundance at its harvest time. The making done by giving treatment about different types and sugar concentration used produce with best characteristics. purpose this research determine effect on characteristics w...

Introduction Many variables are used to assess fruit and vegetable quality. Some quality metrics such as size, shape, and color are relatively obvious and tend to influence “eye appeal.” Others, such as flavor, texture, aroma, and nutrient content, however, are more subjective. They may also require sophisticated techniques and equipment to assess. In addition, these subjective metrics tend to ...

Multilayer coating can be applied on fresh fruit to protect and enhance its shelf life. This study evaluated the application of a multilayer protein chitosan cherimoya. To determinate effect life fruit, total phenolic content, pH, °Brix, weight loss, hardness values were tested. The ripening process is associated with an increase soluble solids, results showed that presence multilayered maintai...

Although tomato paste research has received significant attention, relatively little effort has been addressed to optimization of value-added whole peel and diced tomato processing. Our laboratory has conducted research evaluating tomato attributes which may be indices of peelability and product yield. Eleven tomato varieties were harvested at USDA stage 4 (pink), USDA stage 6 (red) and red plu...

Effect of different wrapping postharvest treatments viz. T0 (control treatment), T1 (White paper), T2 (Brown paper), T3 (Tissue paper) and T4 (News paper) on physical changes of mango var. Langra were analyzed. Among, the treatments, the maximum 5.25 days was required for ripening in Langra which was kept in white paper and minimum 3.573 days for ripening was recorded in control fruits of mango...

Firmness and soluble solid content (SSC) are two important quality attributes. This researches investigated the feasibility of using multi-spectral imaging to non-destructive measuring the apple’s firmness and SSC. The spectral imaging in wavelength of 632nm、650nm、670nm、780nm、850nm and 900nm were captured. The Lorentzian distribution (LD), Gaussian distribution (GD) and Exponential distribution...

Genetic erosion of shea trees, which has been on-going at an alarming rate, necessitated urgent conservation attentions. Owing to the vast geographical distribution species across Ghana, in situ germplasms was established by tagging and monitoring selected trees annually. Technologies have developed that enable be grafted, allowing for development germplasm banks research station Cocoa Research...
