Abstract:
The enzyme catechol oxidase is a protein that produces benzoquinone when the substrate catechol binds to the enzyme. This is commonly referred to as browning. How quickly produce spoils …show more content…
Five potential inhibitors with water as a control were tested to identify the effectiveness of each potential inhibitor based on how the catechol oxidase responded. The first experiment determined which inhibitors lowered the amount of benzoquinone, also known as browning. The second experiment determined which inhibitors were competitive or non-competitive in inhibition. Competitive inhibitors bind to the active site on the enzyme making them more effective by blocking it from being catalyzed; whereas, non-competitive inhibitors bind anywhere to the enzyme changing its shape which may or may not block the active …show more content…
Therefore, based on the data of this lab experiment alone, the competitive inhibitor compound D would be most useful to the food industry since it would have the greatest impact on delaying produce from browning. Some reasons the food industry may not decide to use the most effective inhibitor may be if there is a cost difference between the various inhibitors or if it has a particular smell, taste, or coloring of its own that may deter consumers. However, the most important consideration to be taken into account before spraying this compound all over produce that people are going to eat is whether or not it could affect their health by making them sick or even worse be fatal, such as if it is a

In addition, there is scientific evidence that consumption of Citrus fruits and vegetables helps prevent many degenerative diseases such as cardiovascular problems and several cancers (Rico et al., 2007). Fresh fruits have a natural protective barrier that acts effectively against most plant spoilage and pathogenic microorganisms. However, as a consequence of inappropriate manipulation during the handling, cutting, shredding, and maintenance of the fruit at ambient temperature and storage conditions, both pathogenic and deteriorative microorganisms may contaminate a product, thus increasing the risk of microbial diseases and spoilage (Beuchat, 1996; Díaz-Cinco et al., 2005). In fact, the number of outbreaks and cases of illness caused by consumption of citrus fruits and unpasteurized...

...Dear nutrition student, Thank you for inquiring about my RD/DTR study guide. And yes, there is no catch, the study guide is COMPLETELY FREE! All I ask for is some feedback. So feel free to shoot me any questions/comments! A little background: This study guide is the culmination of years of my own research. And after careful thought, I put into the study guide what I feel are the most important concepts you need to know for the RD/DTR exam. If you notice, I spent much time teaching you in detail the concepts you need to know, not just “spitting” you questions with little or no explanation. I believe this is important. I know you might be thinking “oh, how am I going to absorb and learn all this material?” I say, just read and answer the questions at your own pace. Simply test yourself and of course take some breaks along the way. Just take it one concept at a time. After you have mastered one concept, then move on to the next. I know if you study whole-heartedly what I have outlined in this study guide, you are sure to pass! GOOD LUCK! YOU CAN DO IT! ϑ Your nutrition friend, -Jonathan Brown, B.S, DTR THE “NO FLUFF” RD/DTR STUDY GUIDE *Updated as of July 2011 The “NO FLUFF” RD/DTR STUDY GUIDE Tips for taking the RD/DTR exam 1.

EFSA Scientific Report (2009) 231, 1-107 © European Food Safety Authority, 2009 Review of the potential health impact of β-casomorphins and related peptides SUMMARY Proteins are a very diverse family of large organic compounds involved in many important biological processes. Following their enzymatic hydrolysis during food processing or digestion, proteins may release fragments from their primary amino acid sequence. These fragments are called peptides, and many of them are known to be physiologically active. The possible beneficial effects of bioactive peptides have attracted increasing interest in recent years. On the other hand, there are also reports suggesting that some food-derived peptides might adversely affect human health. Among these, β-casomorphin-7 (BCM7), a peptide sequence present in the milk protein β-casein, has been suggested to...

...hunter, is now herself a hunted woman. Who put the $500,000 price on her head--a man or a monster? It's not just her own skin she needs to save; the rivalry between her werewolf boyfriend, Richard, and Marcus, the other alpha werewolf in his pack, has come to full boil. And there's always Jean-Claude, the vampire who's been waiting for just the right moment to slip inside Anita's head and heart. 1 The most beautiful corpse I'd ever seen was sitting behind my desk. Jean-Claude's white shirt gleamed in the light from the desk lamp. A froth of lace spilled down the front, peeking from inside his black velvet jacket. I stood behind him, my back to the wall, arms crossed over my stomach, which put my right hand comfortably close to the Browning Hi-Power in its shoulder holster. I wasn't about to draw on Jean-Claude. It was the other vampire I was worried about. The desk lamp was the only light in the room. The vampire had requested the overheads be turned out. His name was Sabin, and he stood against the far wall, huddling in the dark. He was covered head to foot in a black, hooded cape. He looked like something out of an old Vincent Price movie. I'd never seen a real vampire dress like that. The last member of our happy little group was Dominic Dumare. He sat in one of the client chairs. He was tall, thin, but not weak. His hands were large and strong, big enough to palm my face. He was dressed in a three-piece black suit, like a chauffeur except for the diamond stickpin in his...
