Globe amaranth is a flower that can be used as natural dye. The has high betacyanin. This study aimed to determine the effect of initial pH and temperature in stability extent globe dye extract, with determined maximum extract during retention. experiment complete randomized design two factors. first factor was consist 4, 5, 6. second storage 4±1ºC 28±2ºC. data were analyzed through analysis va...

The objective of this study was to evaluate the efficacy gamma irradiation, applied different cheese sample sizes (250g and 500 g), against Listeria monocytogenes, Escherichia coli, coliforms aerobic colony counts. effects on physicochemical odour properties all costs involved for treatment were quantified. Cobalt-60 ?-irradiator used at a maximum dose 5.0 kGy. values moisture (28.6%), ash (3.7...

The effects of pH (2.2–8.0) and temperature (25–100 °C) on the instrumental color a model beverage containing (−)-epigallocatechin-3-gallate (EGCG) were investigated. As increased, lightness (L*) decreased while redness yellowness (a* b*, respectively) increased. Using spectral scanning, it was possible to verify that changes might be related structural rearrangement EGCG aqueous solution in sy...

Ochratoxin A (OTA) is a mycotoxin frequently found in wines, with an allowed maximum limit of 2.0 μg/L. To optimise OTA removal from white and red wines at high levels (10.0 μg/L) using activated carbons (ACs) different commercial deodorising ACs were tested. elimination was less dependent on characteristics, 100% all but one AC the lowest total pore volume. For only higher abundance mesopores ...

Rearing of American Pekin ducks in different production systems plays a vital role the determination internal climatic conditions house for optimum health and meat quality parameters. The experiment was designed to evaluate influence rearing fed on kitchen waste parameters ducks. A total 180 ducklings (10 days old) were distributed randomly into three experimental groups; intensive system (IPS)...

Cassava leaf extract can be developed as a natural food coloring. Food coloring from cassava acetone is made in powder form to make it easier use and more stable storage. This study aims determine the effect of type concentration encapsulation on characteristics dye best encapsulant obtain encapsulate. used factorial randomized block design with two factors. The first factor (maltodextrin gum a...

The objective of the present study was to examine some physical and chemical shell kernel attributes promising walnut types selected from Bingol province in Turkey. possesses a rich population almost all which are seedling-grown. Shell cracking resistance, firmness, percentage, pellicle cotyledon color, total oil ratio, phenol content, antioxidant capacity as DPPH were analyzed evaluated. resis...

The present study was conducted to evaluate the addition of a mixture oleaster (OL; E. angustifolia L.) and black cumin (BC; Nigella sativa) flours on quality characteristics toast bread. concentration OL BC (1:1 w/w ratio) 0 (T1), 1.5% (T2), 2% (T3), 2.5% (T4) total flour content. bread samples containing had more protein content (8.49%–9.65%) than control (6.81%; p < .05). highest phenolic co...

The impact of the covering vegetable oil (sunflower oil, refined olive and extra virgin EVOO) on physicochemical sensory profiles canned tuna (Katsuwonus pelamis species) was evaluated, using analytical techniques a panel. results showed that covered with EVOO possesses higher content total phenols an enhanced antioxidant capacity. This medium also increased appreciated redness-yellowness color...

In the present study, sunflower oil was used as extracting solvent for carotenoids and other lipophylic compounds from tomato by-products at 2.5% 5.0% (w/v) carotenoid-enriched oils were further in manufacturing of soy milk mayonnaise. An addition basil essential 0.05% (v/v) mayonnaise also investigated. Color parameters, pH, acid, peroxide values, well lipid oxidation measured by TBARS values ...
