Disclosed herein are methods for efficiently isolating collagen form a collagen source. The methods are inexpensive and do not require the use of proteolytic enzymes, decolorizing agents, antibacterial and antifungal agents, and the like. Further, the collagen produced by the methods described herein is substantially free of odor and discoloration. Still further, the collagen produced by the methods described herein is suitable to be used in cosmetics, food products, and pharmaceuticals or nutritional supplements.

The invention relates to a process for the production of a protein mass from insect larvae, comprising the steps of, cleaning insect larvae, applying pulsed electric fields to the cleaned insect larvae and comminuting the insect larvae to produce an insect mass; and subsequently fractionating the insect mass into a solid and at least one liquid phase with subsequent drying of the solid.

The presently disclosed subject matter provides methods of treating animal proteins and pet food products including the same. Methods include treating animal proteins with one or more base compounds to increase the pH thereof to provide for increased preservation and the reduction of spoilage of the animal protein.

Disclosed here is a process for preparing a concentrated liquid composition (such as a broth) from poultry or other meat sources without the use of any enzymes. The resultant composition may have high content of solids but are pumpable or pourable and have relatively long shelf life at room temperature. Also disclosed are methods of extracting proteins from raw poultry or other meat sources at relatively low temperatures. Methods of making a high protein curd is also disclosed.

Methods of modifying renewable protein sources and uses thereof are provided. In some embodiments, renewable protein sources can be modified to become a flocculant and/or coagulant through the use of a hydrolysis process. Further modifications can be performed in order to enhance the flocculant/coagulant ability of the modified protein material. Such modified protein material can be used to coagulate and/or flocculate waste water colloidal suspensions, either alone or in combination with a coagulant, by mixing the modified protein material with waste water colloidal suspensions to create a mixture and allowing mixture to settle. In some embodiments, the waste water colloidal suspension can be mature fine tailings (MFT).

The present invention relates to a process for growing a feed organism from a composition comprising solid homogenized eggs, comprising collecting eggs that have been exposed to an incubation process; homogenizing the eggs; and subjecting the homogenized eggs to a denaturation process to obtain the solid homogenized eggs; and feeding the solid homogenized eggs to the feed organism. The present invention relates furthermore to the composition, and to its uses.

Disclosed are collagen nanoparticles obtained from waste scaly skins from fish by using a micro fluid technique, a method for obtaining the collagen nanoparticles, and their field of use.

Shown here is a process for preparing a concentrated liquid composition (such as a broth) from poultry or other meat sources without the use of any enzymes. The resultant composition may have high content of solids but are pumpable or pourable and have relatively long shelf life at room temperature. Also shown are methods of extracting proteins from raw poultry or other meat sources at relatively low temperatures. Methods of making a high protein curd is also shown.

A method of sequential isoelectric solubilisation of animal by-product comprising the steps of isoelectric solubilisation of the animal by-product in one of an acid or alkali solution to provide a first solubilised protein fraction, separating the first solubilised protein fraction from unsolubilised animal by-product, isoelectric solubilisation of the unsolubilised animal by-product to provide a second solubilised protein fraction, and separation of the second solubilised protein fraction from unsolubilised animal by-product. The protein from the first and/or second solubilised protein fractions is recovered by drying or precipitation. In one embodiment, the acid and alkali soluble protein fractions are proportionally combined to neutralise the composite fraction and precipitate protein.

The present invention is directed to the utilization of hyperthermophilic organisms to produce single cell protein or protein enriched biomasses for use as food and/or feed sources. In particular, provided is the use of organic material (e.g., animal waste or sludge and/or produce) for use as a biomass in such processes.
