BACKGROUND An excessive consumption of fat has been associated with an increased risk of health problems such as obesity, diabetes and cardiovascular diseases. Cheese is a highly concentrated product which is rich in protein and minerals such as calcium and phosphorus and essential amino acids, therefore it is an important food in the diet. But low fat cheeses are usually characterized as havin...

Keratin solution was separately blended with collagen, gelatin, sericin and starch for films preparation. All the blended films had smooth surfaces without phase separation, except the keratin/ starch blend film. The native keratin film showed small particles embedded in all the film surfaces that resulted in them being rough. The structure of the native keratin film changed from beta-sheet to ...

The effect of solid content (2.5-10%, w/v) and temperature (30-70°C) on the viscosity of tapioca meal from three cassava varieties was investigated in this study. Viscosity measurements were conducted using a digital rotational Brookfield viscometer. The viscosity of tapioca meal increased with increasing solid content and decreasing viscometer speeds. An empirical power-law equation fitted the...

Starch is a major storage product of many economically important crops such as wheat, rice, maize, tapioca, and potato. A large-scale starch processing industry has emerged in the last century. In the past decades, we have seen a shift from the acid hydrolysis of starch to the use of starch-converting enzymes in the production of maltodextrin, modified starches, or glucose and fructose syrups. ...

barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...

the objective of this research was to compare the tensile, permeability, solubility and color properties of plasticized starch-polyvinyl alcohol-montmo-rillonite (ps-pva-mmt) and plasticized starch-polyvinyl alcohol-cellulose nanocrystal (ps-pva-ncc) bionanocomposite flms. the results showed that adding mmt (7%), increased the ultimate tensile strenght from 4.2 mpa to 4.61 mpa, however, ncc (7%...

background and objective: edible, biodegradable films, by acting as barriers to control the transfer of moisture, oxygen, lipids, and flavours, can prevent quality deterioration and increase the shelf life of food products. on the other hand, regarding edible film capacity in transferring food additives, extending shelf-life of food products could be considered. so by adding antimicrobial-antio...

in this study, the effect of mentha piperita essence (mpe) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. the properties included solubility, moisture uptake and contact angle. mpe was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). all biofilms were plasticized with 40...

thyme essential oils (eo) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. it is also used for flavoring and preservation of several foods. nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. in this study thymus ...

Cereal Chem. 76(5):682–687 The effects of starch type on the properties of baked starch foams were investigated. Starch types used for baking were normal corn, normal potato, waxy corn, high-amylopectin potato, wheat, and tapioca. Solids content of the starch batters used to bake foam trays ranged from 25 to 45%. Processing parameters and physical properties of the foams were examined. Starch-f...
