Abstract

Abstract: The SAFE ICE project, supported by the European Commission, addresses and overcomes specific scientific and technological hurdles to make an informed judgment on the relevance of food related effects of High-Pressure in the Low-Temperature (HPLT) domain as well as to realize and to deliver their full benefits to the end users. Such hurdles include the lack of systematic data, and a limited understanding related to the mechanisms involved in phase transitions under pressure at subzero temperatures. The project involves seven partners, bringing together academic and research centres with food industry and equipment manufacturing parties. The main findings of the research carried out in the frame of the project are: the systematic compilation of thermophysical properties of water, aqueous model solutions and model foods to be applied in mathematical models able to reproduce and predict freezing and thawing time profiles at high pressure; the comprehension of the kinetics of phase transition phenomena at HP, including the definition of metastable phases; a key to define critical processing parameters to obtain optimized freezing and thawing paths; the study of the effect of HPLT on key food spoilage enzymes and on microorganisms; the study of consumer acceptance of the technology; the evaluation of the impact of SAFE ICE processes on food quality related parameters and the development of prototypes (HPLT microscopic cell and HPLT differential thermal analysis cell) and process and products concepts for industrial development of SAFE ICE processes.

Abstract

The growth in scientific knowledge and databases available to researchers means that increasingly complex searches are needed to collate information which is both comprehensive and which provides the best quality information on the specific research topic. This study analyzes the number of references identified in CINAHL and MEDLINE and assesses their relevance for undertaking a systematic review. The variables analyzed were the number of references retrieved with and without abstract, the degree of overlap between the databases, and accessibility and degree of relevance of the references. A total of 116 references were retrieved: 49 (42.2%) in CINAHL and 67 (57.8%) in MEDLINE; no overlap was found. Of the retrieved references, 60.3% (70) included abstract, 13 (26.5%) in CINAHL and 57 (85.1%) in MEDLINE (p < 0.005). A total of 62.9% (73) of the identified references were available in Spanish libraries: 42.5% (31) in CINAHL and 57.5% (42) in MEDLINE (p = ns). Twenty-three references were considered relevant (18.9% of the total), of which seven (30.4%) were identified in CINAHL and 16 (69.6%) in MEDLINE (p < 0.005). The agreement between the classification of relevance on the basis of the title and abstract was 72.9% (p < 0.005). To obtain the best results, bibliographical searches on nursing-related subjects should combine CINAHL and MEDLINE. [ABSTRACT FROM AUTHOR]
