Disclosed are novel compositions containing the egg yolk protein phosvitin or peptide fragments thereof. The compositions are substantially free of mineral ions chelated to the phosvitin protein or peptide fragments thereof. The compositions may be used in the formulation of products, including food products, personal care products, or pharmaceutical products, for example, to preserve the products.

The invention discloses a preservation method for fresh blueberry, and relates to the preservation technique field of blueberry. The preservation method of the invention comprises the following steps: step (1): soaking fresh blueberries in an aqueous sodium alginate solution, taking out and drying; step (2): soaking the fresh blueberries treated in step (1) in an aqueous solution containing ε-PL and N,O carboxymethyl chitosan, taking out and drying; step 3: repeating steps (1)-(2). According to the invention, multilayer edible film is coated on the surface of blueberry, so as to extend the storage period of blueberry, thus avoiding the rot and deterioration of blueberry during storage.

A process for the linear synthesis of a gram-positive class II bacteriocin or a variant thereof is disclosed herein. The process comprises the stepwise addition of selected amino acids to a solid support; pseudoproline positioning and reopening; and cleavage of the gram-positive class II bacteriocin or the variant thereof from the solid support to provide a linear gram-positive class II bacteriocin or variant thereof; and in situ disulfide bond formation. Various applications and uses of the synthetic bacteriocins are also disclosed. The synthetic process can also be used to synthesize variants of bacteriocins by the selective substitution of one or more amino acids and/or additions and/or deletions of selected amino acids.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The methods include use of a reactor vessel to degum, rinse, and dissolve the silk fibroin protein from silk inputs to obtain a food grade silk powder. The reactor vessel may include a combination of inputs and outputs for introducing and removing different components used or generated during the process. The systems may include any combination of heat exchangers, holding tanks, filtration modules, and post-treatment equipment as necessary to obtain the silk powder. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.
