Heavy metals can be found in soil as natural components or product of contaminations events; plants growing soils are prone to bioaccumulate heavy on their biomass. Theobroma cacao L. cadmium (Cd) the seed and could derived food products, it considered a human health risk; therefore, removal Cd is desirable but not vet technically economically feasible; only avoid cocoa by selecting lands plots exhibiting lower concentrations soils, imposing serious limitation farmers regulators. The study...
Twelve cadmium native bacteria previously isolated in soils of cocoa farms located the western Colombian Andes (Santander), and tolerant to 2500 µM CdCl2 (120 mg Cd/L), were chosen order test their tolerance Cd immobilization using liquid culture medium (Nutritive broth) at different concentrations heavy metals. Furthermore, greenhouse experiments, strains Exiguobacterium sp. (11-4A), Klebsiella variicola (18-4B), Enterobacter (29-4B) applied combined treatments CCN51 cacao genotype seeds...
Abstract Theobroma cacao is commonly classified as Criollo, Forastero, or Trinitario. In recent years, Criollo has been revalorized due to its low volume production and the increase in premium chocolate market. Besides, origin post‐harvest processes affect chemical volatile composition of cocoa beans that are transformed into liquor raw material for production. Further, there no published information regarding profile Colombian liquor. Based on this, present study aimed characterize...
Abstract Curcuma longa is a rhizome used for the extraction of curcumin, yellow colorant that only represents 3 wt% dried rhizome. To increase possibility using entire as food colorant, in present investigation, effect ultra‐fine friction grinding ( supermasscolloider ) to obtain turmeric suspensions was evaluated. achieve this goal, two distances between stones or Gap were evaluated (G –1 and –1.5), obtained characterized by infrared spectroscopy through determination curcumin content,...
ABSTRACT A strawberry‐gel product was formulated by using osmotic treatment. The solution (OS) used to dehydrate the fruit mixed with carrageenan and employed formulate gel. In order prevent a further dehydration of during storage, OS previously diluted so that its water activity is same as dehydrated fruit. Changes in water, soluble solids, citric acid, ascorbic acid anthocyanin contents, activity, surface color, mechanical properties volatile profile 15 days storage (5C) were evaluated....
BACKGROUND: The development of fruit-based foods that maintain the nutritional and sensory properties fresh fruit may help to stimulate consumption by consumers. possibility formulating a fruit-gel product with osmodehydrated reused osmotic solution (OS) obtained from dehydration step has been demonstrated. However, conditions process can significantly affect product. In this work an at 22 °C for 6 h 30 3 was employed formulate strawberry-gel RESULTS: Significant losses ascorbic citric acids...
Abstract There is growing interest in developing strategies to replace cocoa butter partially or fully food and cosmetic products, because of its cost health effects. One these alternatives the development water stable emulsions, but incorporating into emulsions challenging it solidifies form crystals that cause destabilization. In this research rheological properties nanocellulose shell, a by-product from chocolate industry, were controlled by isolation treatment produce with higher DP...
Actualmente la variedad de frijol seco Cargamanto blanco, en condiciones almacenamiento comunmente utilizadas, presenta deterioro su color, lo que disminuye a vez calidad y genera como consecuencia reduccion del costo venta. Este estudio determino el efecto las empacado color grano blanco (P. vulgaris L.); se evaluo tiempo incidencia los tratamientos aplicados (empacado presencia luminosidad oxigeno, ausencia oxigeno oxigeno) comportamiento coordenadas CIEL*a*b* atributos derivados croma (c)...
The presence of geogenic cadmium (Cd) contaminated environment, especially in soil, has raised serious health hazards through the food chain. Bacteria have been applied for bioremediation cadmium-contaminated environment by biosorption or bioaccumulation interactions; this process is considered as a potential eco-friendly alternative. In present work, twelve native bacteria tolerant to 2,500 µM CdCl2(120 mg/L) isolated soils cocoa farms different levels Cd were selected, evaluate their...
