The capacity of honey to break light is used for refractometric determination humidity. In the present work, a manual refractometer was measure total soluble solids (73% - 86%) which are corresponding values refractive indices stated in Chataway’s Table. relationship between solids, water content and index obtained graphics gave equations that could be directly calculate both from its solids. T...

Tomato (Solanum lycopersicum L.) is one of the vegetables widely cultivated in world, whose fruits are rich nutrients. Soluble solids content (SSC) important factors affecting tomato fruit flavor and plays a decisive role improving quality. Molecular markers genetic that reveal plant polymorphism at DNA level, which have advantages breeding purposes, increasing selection efficiency, shortening ...

The effect of soluble solids on the Zetapotential (ξ) of a cloudy apple juice was investigated. Apple juice was enzymatically treated with pectinolytic enzymes and diafiltred with a polysulphone UF membrane (100 kDa) to eliminate soluble solids. Most soluble solids were removed after 4 equivalent sample volumes (ESV) of washing water. During a second period, from 5 to 23 ESV, diafiltration rate...

This study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-D and naphthalene acetamide application on yield and quality of date palm of ‘Kabkab’ cultivar. The inflorescences sprayed with 2, 4-D isopropylester (0, 10, and 20 mg L-1), naphthalene acetamide (0, 80, and 120 mg L-1), putrescence and spermidine (0, 0.1, and 1.0 mM), three or six weeks after pollin...

BACKGROUND: The impact of organic and conventional production systems on quality and nutritional parameters of fruits and vegetables is still under discussion. The objective of this study is to determine whether the production system has a significant effect on the quality and nutritional content of one variety of processing tomatoes grown on a commercial scale by comparing three different grow...

INTRODUCTION Starch is the predominant carbon sink of storage organs and leaves of many plants. Substantial evidence from the analysis of starch-deficient mutants, transgenic plants, and enzyme kinetics suggest that ADP-glucose pyrophosphorylase (AGPase) catalyzes a key step for starch biosynthesis in both photosynthetic and nonphotosynthetic tissues. Fruit quality in tomato is largely a functi...

Multispectral imaging with 19 wavelengths in the range of 405-970 nm has been evaluated for nondestructive determination of firmness, total soluble solids (TSS) content and ripeness stage in strawberry fruit. Several analysis approaches, including partial least squares (PLS), support vector machine (SVM) and back propagation neural network (BPNN), were applied to develop theoretical models for ...
