Lipid oxidation in food science and nutritional health: A comprehensive review

Food provides abundant nutrients for human beings, but also has sensory functions and physiological regulation.Lipids are the main components of food as well as the important structural and functional components of cells.Nevertheless, lipids are easily oxidized by different ways, such as thermal oxidation and air oxidation. Lipidoxidation has adverse effects on food quality and human health. Therefore, efforts should be made to reduce lipidoxidation and improve its stability. This review focuses on important knowledge about lipid oxidation, includingthe concept of lipids and lipid oxidation, the main pathways and mechanisms of lipid oxidation, factors affectinglipid oxidation, strategies to improve the stability of lipid oxidation, and the recent research progress of lipidoxidation in food science and nutritional health.

Food science and COVID-19

Theories proposing a role of specific dietary components or food supplements in the prevention or treatment of COVID-19 have received extensive social media coverage.A multitude of scientific publications have also pointed to the importance of food and nutrition in combating the COVID-19 pandemic.The present perspective critically addresses the question of what food science can actually contribute in this context.Animal studies suggest that micronutrients,food bioactives or functional foods may carry the potential to augment viral defense.However,the specific roles of food components in viral infectious diseases in humans remain unclear.Rigorous research assessing the efficacy of food compounds in counteracting infections would require long-term randomized controlled trials in large samples.While no foods,single nutrients or dietary supplements are capable of preventing infection with COVID-19,a balanced diet containing sufficient amounts of macronutrients and diverse micronutrients is a prerequisite of an optimally functioning immune system.High-energy diets and obesity are major risk factors for a more severe course of COVID-19.Therefore,population-wide body weight control and weight reduction in overweight people are important preventive measures.Diet may play a beneficial role in maintaining a healthy body weight and preventing non-communicable conditions.

Cultivation of Innovation Ability of Students in the Discipline of Food Science and Engineering from the Perspective of Engineering Professional Certification

Cultivating the top-notch innovative talents is an essential task for connotative construction of higher education.As an applicationoriented discipline,the Discipline of Food Science and Engineering attaches great importance to the cultivation of innovation ability of college students.For a long time,however,the discipline education has problems of the inverted teaching subject position,weak coordination ability and single practice mode.The support for the cultivation of innovation ability is weak and ineffective.Therefore,in the context of professional certification of engineering education,it is necessary to make reform of traditional education mode and improve the carrier support and target acquisition taking the Outcomes-based Education(OBE)as guide,the innovation ability cultivation as objective,to provide effective guarantee for cultivation of the top-notch talents.These have become issues that should not be ignored in the development of the Discipline of Food Science and Engineering.

Potential of sea buckthorn-based ingredients for the food and feed industry-a review

Food industries seek to incorporate nutritious ingredients as they could bring added value to the final food products.One of the most interesting options is that sea buckthorn contains high concentrations of vitamin C,carotenoids,tocopherols,and other bioactive compounds,in addition to the unique lipid profile in the berry pulp,seed,and peel.This review summarizes the state-of-the-art of potential applications of sea buckthorn within the food and feed industry based on previously described applications.Products such as cheese,yoghurt or beverages already benefit from its application.Moreover,using sea buckthorn in feed products also derives into higher quality final products(e.g.meat quality,egg quality).Poultry,pig,and fish farming have been studied for that purpose.Despite all the accumulated articles depicted in the present review,the use of this fruit in food product formulation is nowadays scarce.New options for food product development with sea buckthorn are herein discussed.
