Viscosity control in compositions comprising plant fiber materials

Номер: US20120142909A1
Автор: Brock Lundberg

Pectinases, such as Pectinex™ Ultra SP-L (composed of the enzyme Polygatacturonase, a type of pectinase which is derived from Aspergillus aculeatus ) or pectinmethylesterases were used to decrease or increase, respectively, the viscosity of fiber solutions, especially solutions with highly refined cellulosic thickeners, and particularly those made of highly refined cellulosic parenchyma cell wall fiber solutions. The enzyme can reduce the viscosity up to 95% or increase the viscosity 100 fold. At lower concentrations the enzyme requires up to a few days of reacting to reach the full reduction in viscosity. Pectinex™ Ultra SP-L has an optimum pH of 4.5-5 and a temperature optimum of 40° C. By controlling the viscosity available from the dried, treated highly refined cellulosic fiber compositions, tailored powder compositions can be provided that will provide precise viscosities when rehydrated in solutions at a constant concentration.

Release agent compositions for treating food netting include hydrophilic (e.g., acidic) and hydrophobic (e.g., surface active amphiphilic modifier, oil) components that both enhance the releasability of a food product from the treated netting material. The acid of the release agent composition denatures proteins along an outer surface of the food article, forming a skin of insolubilized proteins between the netting material and the remainder of the food product. This protein skin, along with the oil, if present, and a surface active amphiphilic modifier of the release agent, inhibit absorption and/or adsorption of hydrophilic food proteins from the food product into or onto the netting, which inhibits strong mechanical binding between the netting and the food product. Subsequent release of the netting from the food product is relatively easy, without damaging the food product itself. Related articles and methods are also disclosed. 1.

The present invention describes synthesis and properties of cellulose based biodegradable hydrophobic mulch film for agricultural applications. The invented method can also be used to obtain an highly hydrophobic mulch film. Cellulose, the most abundant natural polymer is chemically modified to make bio-degradable, mulch films that are partially air permeable but water impermeable. The water impermeability can be changed by varying the processing conditions. The film can be multi-functional; that is besides providing the water impermeability the film can also be customized to adjust the pH of soil and to deliver herbicides or fertilizers to the soil. Other lignocellulosic materials or different combinations of synthetic fibers, fabrics or polymers and cellulose materials including newsprint can also be used to make the biodegradable hydrophobic film. Additionally, the invention can be used to make biodegradable extremely hydrophobic self-cleaning products for other hydrophobic applications such as packaging materials or disposable water-proof clothing. 1. A biodegradable hydrophobic material comprising cellulose and a hydrophobic agent or sizing agent , wherein hydroxyl groups of the cellulose have been activated by a base , and then the hydroxyl groups have been reacted with the hydrophobic agent or sizing agent to cap the hydroxyl groups.2. The biodegradable hydrophobic material of claim 1 , wherein the cellulose is a cellulosic feedstock selected from newsprint claim 1 , cellulose pulp claim 1 , lignin-cellulose-hemicellulose or a mixture thereof.3.
