Modified Cellulose Fibers and Preparation Method

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses a novel method for producing modified cellulose fibers, intended primarily for clarifying (removing haze-forming substances from) liquids such as beer, wine, or juice. The process involves enhancing cellulose fibers with crosslinked carboxymethylcellulose (croscarmellose sodium) and optional additives, yielding a filtering aid that can effectively replace traditional diatomaceous earth (kieselguhr) used in beverage filtration. The modified cellulose fibers can be used alone or in combination with other filtering methods in varied industrial settings.

Use CasesContent extracted from patent full text and abstract with AI.

• Filtration and clarification of beer, wine, and other beverages to produce clear, bright products.
• Replacement of conventional kieselguhr filters in breweries and winemaking facilities, reducing health and environmental risks.
• Processing of fruit juices and similar liquids to improve turbidity and shelf-stability.
• Use in water treatment and other industrial liquid filtration processes where removal of haze, proteins, or colloidal particles is required.
• Production of filter aids and filter plates for existing filtration infrastructure in the beverage industry.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides an effective, sustainable, and food-safe alternative to carcinogenic kieselguhr (diatomaceous earth) filters.
• Reduces the amount of harmful iron and heavy metals introduced during the filtration process, improving flavor stability and oxidative resistance of products such as beer.
• Composed primarily of cellulose, which is renewable, biodegradable, and easier to dispose of (including composting or use in animal feed).
• Enables flexible adaptation to existing filtration equipment, minimizing investment costs for beverage producers.
• Requires lower mass for equivalent filtration performance, reducing operating and disposal costs.
• Enhances removal of haze-forming proteins and polyphenols, thus improving product clarity and shelf life.
• Minimizes health and ecological hazards associated with production, use, and disposal of traditional filter aids.
