Abstract
Several health benefits of conjugated linoleic acid (CLA) have been documented. The present work is aimed to review data on the various factors affecting the CLA content in cheese of studies accomplished in the last decade and also indicating the factors that increase the CLA levels. The CLA content in cheese depends on CLA levels present in milk, since the lipids with the CLA are transferred from milk into the cheese. Feed types rich in α-linolenic and linoleic acids such as pasture grass, plant oils, cereals rich in oil, or fish oils can affect the CLA level in milk. In contrast to findings of previous reviews made in previous decade, which stated that the CLA levels in cheese were stable during ripening time, the present review reveals that certain lactic acid bacteria, that is, probiotic Lactiplantibacillus plantarum, Lactobacillus acidophilus, or Lacticaseibacillus casei, as well as Bifidobacterium lactis can increase the CLA levels in cheese by converting linoleic acid during ripening time. These bacteria starters increased the CLA levels by 1.19, 1.6, and 6.6 times as much as the control in Ovine model, Miniature, and Cheddar cheese, respectively. Lipid oxidation due to factors like fluorescent light or aerobic conditions can decrease the CLA levels during storage.
期刊介绍：
The goal of the Journal of Food Science is to offer scientists, researchers, and other food professionals the opportunity to share knowledge of scientific advancements in the myriad disciplines affecting their work, through a respected peer-reviewed publication. The Journal of Food Science serves as an international forum for vital research and developments in food science.
The range of topics covered in the journal include:
-Concise Reviews and Hypotheses in Food Science
-New Horizons in Food Research
-Integrated Food Science
-Food Chemistry
-Food Engineering, Materials Science, and Nanotechnology
-Food Microbiology and Safety
-Sensory and Consumer Sciences
-Health, Nutrition, and Food
-Toxicology and Chemical Food Safety
The Journal of Food Science publishes peer-reviewed articles that cover all aspects of food science, including safety and nutrition. Reviews should be 15 to 50 typewritten pages (including tables, figures, and references), should provide in-depth coverage of a narrowly defined topic, and should embody careful evaluation (weaknesses, strengths, explanation of discrepancies in results among similar studies) of all pertinent studies, so that insightful interpretations and conclusions can be presented. Hypothesis papers are especially appropriate in pioneering areas of research or important areas that are afflicted by scientific controversy.
