Despite the effective disruption efficiency, the recovery of bio-active compounds by bead mill requires intensive, energy demanding cooling. The disruption of yeast cell wall by bead mill was affected by impact of beads or paddles and has a possibility to destroy the very proteins being sought ( Goldberg, 2015 ).

The Ultimate Guide to Ball Mills. Ball mill is a common grinding equipment in concentrator, the main role is to provide qualified grinding products for the subsequent dressing process. The ball grinding process is a process in which the steel ball rotates in the cylinder at a certain speed and rises with the wall of the cylinder.

The effects of processing were evaluated for the extraction yield, protein, fat, and total phenolic content, fatty acid composition, particle size and zeta potential, and FTIR spectra. The use of ILs and the ball mill process significantly (P < 0.05) affected the extraction yield and physicochemical properties.

Among them, only four anhydrous and six hydrated DESs were able to extract oat proteins from flours by one-step extraction. SDS-PAGE and FTIR analyses indicated that the structural properties of the oat proteins were highly reliant on the composition of the DESs; while physicochemical properties were primarily ruled by the …

The two most popular mechanical techniques for sample preparation for large-scale protein production are concussion and liquid shear. One concussion device is the ball mill, in which the cells are agitated in suspension with small abrasive particles such as glass beads, silica or sand.

The aim of this study was to develop a protein extraction process via ultrasonication from soybean residue (okara) under alkaline conditions. It is hypothesised that ultrasonication could enhance the release of proteins located in the protein bodies of palisade-like cells in soybean cotyledon within a short time and could possibly preserve …

The utilisation of palm oil processing effluents as substrates for microbial protein production by the fungus Aspergillus oryzae

Fractionation of the fine protein-rich particles from the coarse carbohydrate-rich particles can be performed as a function of their size and density through air classification. Centrifugal air classifiers are among the most commonly used modern classifiers for partial separation of plant proteins from various agro-materials.

Recently, a new type of extraction method, named mechanochemical-assisted extraction (MCAE), has emerged, whose mechanism mainly is when the raw materials and grinding medium are added into ball mill with zirconia ball grinding beads, the mechanical force and chemical reaction will be generated, and thus broke down …

Here, a thorough study of the most suitable solvent, extraction time and temperature for the large-volume, solid-liquid extraction of bioactive compounds has been made, in order to achieve maximum concentrations of the target compounds.

The effects of ball mill treatment (0, 2, 4, 6, 8, and 10 min) on the physicochemical and digestible properties of scallops (Chlamys farreri) protein (CFP) were investigated. The CFP particle size decreased with increasing ball-milling time. The content of free sulfhydryl (SH) of CFP increased from 13.08 ± 0.25 μmol/g protein to …

It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA and protein extraction. With its high performance and great flexibility the mixer mill MM 400 is a unique product in the market. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.

Cell disruption is the initial step in the manufacturing of many biological products such as enzymes, nucleic acids, reporter assays, immunoassays, protein purification, antigens for vaccines, and viral vectors that deliver genes for next-generation vaccines or gene therapy.

Conclusions. In this review, aqueous extraction from whole soybeans has been detailed, with a focus on protein extraction. During a whole soybean extraction process, soybeans are first ground, and the intracellular components are then extracted into the medium followed by separation of the okara waste stream.

In this study, secondary sludge (SS) from a kraft paper mill was used as a source of biomass to recover protein and investigate its potential use as a wood adhesive.
