SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Journal of Functional Foods aims to bring together the results of fundamental and applied research into functional foods (ie those containing various factors to ensure or enhance health) and their development and commercialization in food products. The journal will cover (but will not be restricted to) the fields of plant bioactives; antioxidants and ageing; dietary fibre, prebiotics and functional starches; probiotics and probiotic functional foods; functional lipids; bioactive peptides; vitamins, minerals and botanicals and other dietary supplements; functional beverages and food products; and molecular nutrition and other relevant aspects of disease prevention and treatment.
Papers will cover such issues as new functional food bioactives; efficacy and safety of bioactive compounds and other functional food constituents using genomic technologies, bioassays and dynamic models; characterisation of functional foods and functional constituents with reference to product development; preparation of natural and synthetic ingredients for use in foods, supplements or premixes and improvement of ingredient quality; use of natural and synthetic ingredients in foods, supplements or premixes, effects of processing (including packaging, storage etc) on functionality and improvement of product quality; verification, quality control and traceability of natural and synthetic functional food ingredients and products; improvement of the quality of foods with inherent health benefits ; development and commercialisation of specific functional food products, supplements or functional ingredients; and the regulatory aspects of functional foods and related issues eg labelling, substantiation of health claims.
