We present herein an experimental study on the ice-nucleation kinetics of two recently introduced aqueous supercooling modalities—oil-sealed isobaric and isochoric supercooling. A series constant-cooling rate experiments compare apparent nucleation temperatures pure water supercooled under these modalities with conventional open-air supercooling, demonstrating that both methods significantly en...

JUNE 2005 SUPPLEMENT T o many scientists, researchers, and technicians, the discipline of biopreservation (commonly known as cryobiology) remains an afterthought in product and process development. Biopreservation is a simple means to an end for storing/shipping intermediate biological materials or final products. It is, however, an extensive and involved process. Contributing to the general pe...

background and objective: constant use of limited number of lactic acid bacteria species in biopreservation can cause genetic degradation and or rising resistance against food pathogens or antimicrobial substances they produce. for this objective, a newly isolated strain of lactobacillus acidophilus possessing high antimicrobial activity was evaluated as a candidate for use in biopreservation. ...

Atlantic horse mackerel (Trachurus trachurus) fillets were coated by gallic acid and chitosan solutions, including nanoparticles, fish quality shelf life assessed during chilled storage for 13 days. All chitosan-containing coatings decreased microorganisms’ growth in more than 2 log cycles up to late stages; however, those with nanoparticles resulted be effective, probably due a greater contact...

As member of the lactic acid bacteria (LAB), the genus Lactobacillus represents a diverse number of species that play significant roles in the biopreservation of foods and commensals common within the human gastrointestinal (GI) tract. Certain species of Lactobacillus, particularly those of human origin, have been used as probiotic bacteria due to their health-promoting effects. A recent explos...
