Abstract: Canola protein isolate has been suggested as an alternative to other proteins for human food use due to a balanced amino acid profile and potential functional properties such as emulsifying, foaming, and gelling abilities. This is, therefore, a review of the studies on the utilization of canola protein in human food, comprising the extraction processes for protein isolates and fractions, the molecular character of the extracted proteins, as well as their food functional properties. A majority of studies were based on proteins extracted from the meal using alkaline solution, presumably due to its high nitrogen yield, followed by those utilizing salt extraction combined with ultrafiltration. Characteristics of canola and its predecessor rapeseed protein fractions such as nitrogen yield, molecular weight profile, isoelectric point, solubility, and thermal properties have been reported and were found to be largely related to the extraction methods. However, very little research has been carried out on the hydrophobicity and structure profiles of the protein extracts that are highly relevant to a proper understanding of food functional properties. Alkaline extracts were generally not very suitable as functional ingredients and contradictory results about many of the measured properties of canola proteins, especially their emulsification tendencies, have also been documented. Further research into improved extraction methods is recommended, as is a more systematic approach to the measurement of desired food functional properties for valid comparison between studies.
Abstract The single radial immunodiffusion assay has been the accepted method for determining the potency of inactivated influenza vaccines since 1978. The world‐wide adoption of this assay for vaccine standardisation was facilitated through collaborative studies that demonstrated a high ... more
Abstract Background Whether morbidity from the 1918‐19 influenza pandemic discriminated by socioeconomic status has remained a subject of debate for 100 years. In lack of data to study this issue recent literature have hypothesized that morbidity was “socially neutral”. Objectives ... more

Some doctors may recommend that patients with the flu take acetaminophen, or paracetemol, to relieve their symptoms; however, a new randomized clinical trial found no benefits to the over-the-counter medication in terms of fighting the influenza virus or reducing patients' temperature or ot ... more
