In this preliminary study, the effect of regulated deficit irrigation (RDI) on commercial quality (size, weight, soluble solids, firmness and colour), content carotenoids, phenolics sugars black tomato (Solanum lycopersicum L.) ?Sunchocola? was studied. Two water treatments were applied: control with 82,7 398 mm supplied, respectively. Tomato first cluster harvested at three stages maturity The...

We evaluated the physicochemical properties of Platycodon grandiflorums jelly prepared six different concentrate levels to develop with improved functionality. As content increased, moisture and pH tended decrease, soluble solids increase, but no significant variation existed. The L value decreased as concentration increased. Conversely, a b values increase. Texture profile revealed, strength h...

Understanding how the environment and production and cultivation practices influence the composition and quality of food crops is fundamental to the production of high-quality nutritious foods. In this 3-year study, total phenolics, percent soluble solids, ascorbic acid, and the flavonoid aglycones quercetin, kaempferol, and luteolin were measured in two varieties of tomato (Lycopersicon escule...

Ohmic heating is defined as a process which alternating electric current is passed through food with the primary purpose of heating it due to the electrical resistance and can be specially applied as an alternative heating method. In this research, Aloe vera gel concentrates having 0.5-2% soluble solids were ohmically heated up to 60°C by using four different voltage gradi...

Effects of kaolin applicati on were evaluated on water stress in pistachio cv. ‘Ohadi’. This experiment was conducted in one of research sites at the Pistachio Research Institute in Rafsanjan (Kerman province) in . The results show that individual and interaction effects of all treatments were significant on nutrition absorption in leaves, although there was not a steady effect on all the eleme...

the aim of this study was the increasing of leachate quality using integrated membrane bioreactor (mbr). the reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the analysis of cod, biochemical oxygen demand (bod5), total suspended solids (tss), and total dissolved solids (tds) were performed in feed and filtrate, whenever the system reached steady stat...

Liquid livestock waste can be managed by separating liquid and solid fractions then treating each separately by applying best available technology, such as anaerobic digestion for the solid fraction. There is an increasing use of polyacrylamide (PAM) as a flocculant agent to improve solid-liquid separation. In the present work, the anaerobic toxicity of PAM residues and the optimal range of tot...

Whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. In this study, selective separation of whey components by Aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. It has been shown that it is possible to recover valuable components of w...

Grape processing residues are a good source of bioactive and nutritional compounds. The incorporation grape pomace extract (GPE) in starch films can be strategy for the elaboration new food packaging products applications such as edible or fruit strips. In this context, objective research was to analyze effect variation concentration GPE (0, 20, 30, 40% mass/mass solids) on physical chemical pr...
