Conventionally, glycerol has been used as plasticizer for gluten, but several new plasticizers have also been reported to provide better stability and mechanical properties. 12 It was shown...
New plasticizers for wheat gluten films - ScienceDirect
Wheat gluten films were prepared with glycerol, diethanolamine or triethanolamine as the plasticizing agent. The influence of these substances on the gluten film properties were studied at two RH conditions (58% and 98%) and for two amounts of plasticizer (10 g and 20 g/100 g dm). 3.2.1.
Wheat Biocomposite Extraction, Structure, Properties and
Adding plasticizer to wheat starch improves the physical and mechanical properties because plasticizer increases the flexibility of the material. There are many types of plasticizer such as, fructose, sorbitol, urea and glycerol used to improve physical and mechanical properties.
Wheat gluten films obtained by compression molding
Film packaging based on wheat gluten can improve food storage, mainly as a result of its ability to act as barrier to water, preventing dehydration, and to oxygen and light, reducing lipid oxidation. It can also be used to incorporate functional agents such as antimicrobial, antioxidants, probiotics, etc. to food products [11].
Edible wheat gluten (WG) protein films | SpringerLink
Commercial wheat gluten (WG) films, hard wheat gluten films and soft wheat gluten films, plasticized with glycerol have been cast from water–ethanol solutions. The effect of aging on various film properties has been investigated. The films were aged for about 6 months at 50% relative humidity and ~25 °C, and the mechanical (tensile strength and the percentage of elongation at break (E b
- Who makes wheat gluten concentrate powder?
- The wheat gluten concentrate powder was manufactured by Lantmännen Reppe AB, Sweden. It has a protein content of 86.3 ± 0.3 (Dumas method, NMKL 6:2003, USA, N x 6.25). The fat content was 0.9 ± 0.1% (2009/152/EU mod) and the ash content was 0.8 ± 0.1%, (NMKL 173). Glycerol (>99.5%) was purchased from PWG Produkter AB, Sweden. 2.2.
- What is efficient plasticization?
- Efficient plasticization is referred to here as when the added plasticizer gives the demanded/sufficient toughness/ductility of the material for a specific application, and may hence be different for different applications. It implies the avoidance of an “apparent” brittleness [14 ].
- Is wheat gluten a polypeptide?
- Wheat gluten is a complex mixture of different polypeptides and the rationale for describing it with the LMW-gs polypeptide is its high abundance and that the plasticization effect of glycerol and water would not depend strongly on the actual peptide simulated.
- Is glycerol a plasticizer?
- Despite having three hydroxyl groups per molecule, glycerol's efficient plasticization (turning brittle biopolymers into tough/flexible materials) occurs typically at a relatively high plasticizer content.
- How is wheat gluten mixed with glycerol?
- As-received wheat gluten was mixed with glycerol into a dough in a dough maker (Kenwood Major KM615 900 W, Kenwood Ltd, UK) at a moderate stirring rate for 5 min. Samples with a glycerol content of 20, 22, 24, 26, 28, and 30 wt%, with respect to the total mass of wheat gluten and glycerol, were prepared.
- Does gliadin/glutenin affect dough rheological properties and bread-making potential?
