The Impact of Saccharin on Saccharomyces Cerevisiae Yeast
Journal of Undergraduate Biology Laboratory Investigations 2018 The Impact of Saccharin on Saccharomyces Cerevisiae Yeast Fermentation Parker Brown, Megan Hanson, Edison Huo, Derica Smith, and Bianca Galletti * 1 University of Oklahoma, Department of Biology, 730 Van Vleet Oval, Room 314 Norman, OK 73019 _________________________________________________________________________________________ Previous research has shown that mammals struggle to metabolize sugar substitutes such as saccharin. But these results are less clear when it comes to microorganisms such as yeast. Because many animals cannot metabolize saccharin, we hypothesize that yeast growth will be less in saccharin dominate solutions as compared to glucose dominate solutions. To test this, differing solutions of glucose and saccharin were fed to Saccharomyces cerevisiae, a yeast type which uses the Crabtree Effect to carry out alcoholic fermentation in the presence of glucose. Like in animals, it was found that saccharin also negatively impacts the growth of yeast meaning that saccharin could not be used in industrial processes wishing to use yeast to make ethanol. _________________________________________________________________________________________ Introduction sugars in processes requiring yeast growth such as In the last several decades, sugar substitutes the alcoholic beverage industry. have become more common in the food and Because yeast is a commonly used organism beverage industry as they allow “healthier” low in the food industry, the process of yeast calorie foods to be produced and marketed to fermentation has been well established. In certain consumers. However, these sugar substitutes have types of yeast, such as Saccharomyces cerevisiae, not been introduced without controversy with past yeast can utilize glucose to undergo alcoholic research voicing their harmful impacts and others fermentation in what is called the Crabtree Effect revealing no deleterious impacts (Sharma et. -
Popular Sweeteners and Their Health Effects Based Upon Valid Scientific Data
Popular Sweeteners and Their Health Effects Interactive Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science By __________________________________ Ivan Lebedev __________________________________ Jayyoung Park __________________________________ Ross Yaylaian Date: Approved: __________________________________ Professor Satya Shivkumar Abstract Perceived health risks of artificial sweeteners are a controversial topic often supported solely by anecdotal evidence and distorted media hype. The aim of this study was to examine popular sweeteners and their health effects based upon valid scientific data. Information was gathered through a sweetener taste panel, interviews with doctors, and an on-line survey. The survey revealed the public’s lack of appreciation for sweeteners. It was observed that artificial sweeteners can serve as a low-risk alternative to natural sweeteners.

ATTACHMENT 3 SAFETY ASSESSMENT REPORT APPLICATION A406 PERMISSION FOR USE OF NEOTAME SUMMARY Introduction The NutraSweet Company is seeking approval for the use of a new artificial sweetener (Neotame) in Australia and New Zealand. The proposed uses include, but are not limited to, soft drink beverages (both carbonated and non-carbonated), beverage concentrates, beverage mixes, dairy beverages, fruit juice products, alcoholic drinks, non-dairy desserts, gelatin, ice cream, breakfast cereals and as a tabletop sweetener for use in hot beverages such as tea or coffee. Neotame (L-phenylalanine, N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-,1-methyl ester; or NC- 00723) is a dipeptide methyl ester derivative, chemically-related to aspartame. It has a sweetness potency of 7000 to 13,000-times sweeter than sucrose, and 30 to 60-times that of aspartame, depending on the use. Neotame was very stable in mock beverage solutions simulating commercial formulations. The only degradation product formed at >1% was L-phenylalanine, N-[N-3,3-dimethylbutyl)- L-α-aspartyl (NC-00751), which is also the major metabolite in both animals and humans and other minor degradation products (each <1%) which are not expected to be detectable at actual use levels of Neotame. Metabolism and toxicokinetics A number of studies on the metabolism and toxicokinetics were performed in rats and dogs, mainly via the oral route, although the intravenous route was also investigated. Neotame was rapidly absorbed following oral dosing, with around 14% of the administered dose absorbed in a pilot metabolism study and around 20-30% absorbed in the definitive rat metabolism study. -
Effects of Saccharin Consumption on Operant Responding for Sugar
foods Article Effects of Saccharin Consumption on Operant Responding for Sugar Reward and Incubation of Sugar Craving in Rats Kenjiro Aoyama * and Akane Nagano Department of Psychology, Doshisha University, Kyotanabe-shi, Kyoto 610-0394, Japan; [email protected] * Correspondence: [email protected] Received: 11 November 2020; Accepted: 5 December 2020; Published: 8 December 2020 Abstract: Repeated experience with artificial sweeteners increases food consumption and body weight gain in rats. Saccharin consumption may reduce the conditioned satiety response to sweet-tasting food. Rats were trained to press a lever to obtain sucrose for five days. A compound cue (tone + light) was presented with every sucrose delivery. On the following day, each lever press produced only the compound cue (cue-reactivity test). Subjects were then provided with yogurt for three weeks in their home cages. The rats were divided into two groups. Rats in the saccharin group received yogurt sweetened with saccharin on some days and unsweetened yogurt on others. For the plain group, only unsweetened plain yogurt was provided. Subsequently, the cue-reactivity test was conducted again. On the following day, the rats underwent a consumption test in which each lever press was reinforced with sucrose. Chow consumption and body weight gain were larger in the saccharin group than in the plain group. Lever responses increased from the first to the second cue-reactivity tests (incubation of craving) in both groups. During the consumption test, lever responses were higher in the saccharin group than in the plain group, suggesting that the conditioned satiety response was impaired in the saccharin group. -

More than half of people in the US are becoming overweight, of which more than half are obese. As a result the weight related disorders are on the rise. So with all of these weight related problems going around, increased number of people struggling with weight lost regimens. They are trying to change their eating habits to include more vegetables and whole grains in their diets. They’re trying to be more physically active. They’re trying to modify snacking choices to healthier ones. There has been found an increasing trend of substituting artificial sweeteners in the sweet snacks and drinks that make up the majority of the American diet. But the question is that - are these substitutes really going to help? Or are they going to do more harm than benefit? The research has shown mixed evidences, but more and more is showing that these artificial sweeteners are not a good substitute. Artificial sweeteners continue to be a controversial public health issue, and the research keeps coming. At one side, many people are strongly opposing the use of artificial sweeteners because of the reported connections with increased risk for cancer and other metabolic and degenerative diseases. -

Sweet Sensations by Judie Bizzozero | Senior Editor
[Confections] July 2015 Sweet Sensations By Judie Bizzozero | Senior Editor By R.J. Foster, Contributing Editor For many, terms like “reduced-sugar” or “sugar-free” do not go with the word “candy.” And yet, the confectionery industry is facing growing demand for treats that offer the taste people have grown to love without the adverse health effects they’re looking to avoid. Thankfully, there is a growing palette of ingredients from which candy makers can paint a new picture of sweetness that will be appreciated by the even most discerning of confectionery critics. SUGAR ALCOHOLS Also referred to as polyols, sugar alcohols are a common ingredient in reduced-sugar and sugar-free applications, especially confections. Funny thing, they’re not sugars or alcohols. Carbohydrate chains composed of monomeric, dimeric and polymeric units, polyols resemble both sugars and alcohols, but do not contain an ethanol molecule. All but two sugar alcohols are less sweet than sugar. Being only partially digestible, though, replacing a portion of a formulation’s sugar with a sugar alcohol reduces total calories without losing bulk (which can occur when replacing sugar with high-intensity sweeteners). Unique flavoring, texturizing and moisture-controlling effects also make polyols well-suited for confectionery products. Two very common and very similar monomeric polyols are sorbitol and mannitol. Present in a variety of fruits and vegetables, both are derived from products of cornstarch hydrolysis. Sorbitol is made via hydrogenation of glucose, which is why sorbitol is sometimes referred to as glucitol. Mannitol is created when fructose hydrogenation converts fructose into mannose, for which the final product, mannitol, is named. -

Abstract: Aspartame is a sweetener introduced to replace the commonly used sucrose. It was discovered by James M. Schlatter in 1965. Being 180–200 times sweeter than sucrose, its intake was expected to reduce obesity rates in developing countries and help those struggling with diabetes. It is mainly used as a sweetener for soft drinks, confectionery, and medicines. Despite its widespread use, its safety remains controversial. This narrative review investigates the existing literature on the use of aspartame and its possible effects on the human body to refine current knowledge. Taking to account that aspartame is a widely used artificial sweetener, it seems appropriate to continue Citation: Czarnecka, K.; Pilarz, A.; research on safety.
