Amylases are one of the main enzymes used in industry. Such enzymes hydrolyze the starch molecules into polymers composed of glucose units. Amylases have potential application in a wide number of industrial processes such as food, fermentation and pharmaceutical industries. α-Amylases can be obtained from plants, animals and microorganisms. However, enzymes from fungal and bacterial sources hav...

In the present study, a better knowledge of the influence of plasticizer content, storage relative humidity and film thickness on the mechanical properties of high amylose corn starch based films gelatinized at low temperature, is presented. The mechanical properties, tensile strength and percentage of elongation at break of high amylose corn starch films plasticized with glycerol were evaluate...

Shear and heat milling machines (SHMMs) constitute a recent mechanical approach that holds promise for the generation of amorphous starch. Here, an tapioca starch SHMM method is developed. The provides higher efficient instant way amorphization rice compared to conventional methods as pressure treatment, ball so on. In this study, temperature initial moisture content are varied, respectively, 8...

Starch based carbon nanotubes-iron oxide (CNT-IO) and nanotubes-zirconium (CNT-ZO) nanocomposites (NCs) were fabricated using facile microwave irradiation technique from different plant-based starch sources namely Tapioca sago (TS), Hordeum vulgare (HV) Eleusina coracona (EC) metal precursor solutions. The prepared NCs studied by characterization techniques such as SEM, TEM, XRD, Raman spectros...

The use of plastic film in agriculture has the serious drawback of producing vast quantities of waste. In this work, films were prepared from natural fibers and biodegradable polymers as potential substitutes for the conventional non-biodegradable plastic film used as mulching material in agricultural production. The physical properties (e.g., mechanical properties, heat preservation, water per...

Dans cet article, nous détaillons et étudions TAPIOCA (distribuTed and AdaPtive IntersectiOns Control Algorithm), un algorithme distribué qui défini les séquences et durées des feux verts dans un système de transport intelligent. TAPIOCA s’appuie sur les données recueillies par un réseau de capteurs sans fil déployé aux intersections afin de décider localement de son programme. TAPIOCA ne se re...

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 ...
