Analysis Of Glycosylated Casein In Whole Milk Powder, Sun Jingli, Li Linqiang, Zhu Lili, Tang Lu, Wu Yuan

Food and Machinery

This study investigated glycosylated casein in whole milk powder and explored its enzymatic property. The casein extraction weight percentage were determined by different pH, different acids, and different methods. The casein was analyzed by SDS-PAGE electrophoresis, and the glycosylated casein were identified via the method of periodate-schiff alkali dyeing and the experiment of morse. The casein was hydrolyzed by papain and the amino acid content was determined accordingly. Results: The percentage of casein extracted under pH 4.6 was significantly higher than that of other groups (P<0.05). The weight percentage of casein extracted from acetic acid (pH 3.58) was (4045±0.66)%, which was significantly higher than that of other groups (P<0.05). The percentage (46.13±0.46)% of casein extracted by tannic acid was significantly higher than that of other methods (P<0.05). The results of casein SDS-PAGE electrophoresis both showed the same 3 bands either different acids or different methods on casein extraction, and their molecular weights were 34, 24, and 60 ku, respectively, and the 34 and 24 ku were glycosylated casein by the method of periodate-schiff alkali dyeing. The results of morse experiment showed that milk powder casein exist glycosylated casein. The content of free amino acid from whole milk powder was significantly higher than that from fresh milk after papain hydrolysis (P<0.05). Whole milk powder has glycosylated casein, their molecular weights are 34 and 24 ku respectively, which are easy to hydrolysis.

Weird Science: Frankenstein Foods And States As Laboratories Of Democracy, Jennifer Mcgee

Journal of Law and Health

The National Bioengineered Food Disclosure Standard (the 'National Standard') was signed into law July 29, 2016. This Article analyzes the National Standard and posits that Vermont’s Act 120 was a more effective labeling law because it safeguarded consumer sovereignty. The State regulatory scheme in place prior to the passage of the National Standard satisfied consumer demand for disclosure while allowing for necessary experimentation with GMO labeling. Part I provides an overview of the current federal scheme regulating GMOs. Part II analyzes of the conflict surrounding GMOs and labeling. Given that analysis, Part III compares the disclosure requirement of the National …

Making Lifestyle Choices To Reduce Late-Life Depression Risk, Maria C. Norton, Elizabeth B. Fauth, Jessica Weyerman

All Current Publications

Depression is a complex condition involving insufficient levels of brain chemicals, life stressors, thought processes, behaviors, and coping mechanisms. Medications and counseling therapy are effective in treating depression, and research suggests that several lifestyle practices also help to protect us from depression, and speed up our recovery if we do experience it. These behaviors, such as being socially connected, eating healthy and exercising, cost little to nothing but can have profound benefits on our overall quality of life and help us to stay depression-free.
