Starch-based Bioplastic Made from Autocarpus heterophyllus (jackfruit) Rags An entry to the FEATI Leandro B. Buates Karen Francisco Aubrey A. Locsin Patricia Joy D. Silva Proponents Ms. Luzviminda A. Dinglasan Research Adviser I. Introduction Brazil disposes of approximately 240,000 tons of waste per day). Of that total, a large amount goes to open wastes deposits. Only small quantities is disposed in appropriate places. (Vilpoux and Averous, 2002). In the Philippines, it is necessary to address the plastic waste due to its high accumulation in dumpsites. In fact, a study conducted by NSWMC, states that Metro Manila is said to contribute 6700 tons of solid wastes per day (Ang, 2013). The world production of plastic is estimated …show more content…
The white particles at the bottom of the beaker showed that starch was extracted from jackfruit rags using 200 ml of distilled water. The decaying period of the bioplastic indicated that starch can be easily degrade. The strength test was able to indicate the maximum weight that the plastic can carry. Therefore, the starch from Aitocarpus heterophyllus (Jackfruit) rags can be one source of starch that can be used in bioplastic production. The study can be improved by manipulating the amount of starch to determine its effect on the strength, and decaying period of the bioplastic …show more content…

In this experiment, one tested solutions that consisted of the standard yeast solution and added raw materials of interest. First, one measured and then added seven grams of Fleischmann 's Rapid-Rise yeast to a bottle containing two hundred and fifty milliliters of warm distilled water for the purposes of creating the standard yeast solution that was used in the fermentation experiment. Next, the standard yeast solution was added to each of the four fermentation flasks. After swirling the bottle, one and a half grams of the fermentation substrate was added into a beaker with fifteen milliliters of yeast suspension. The fermentation flask marked one required one and a half grams of Zulka Brand Morena Pure Cane Sugar as the fermentation substrate, the fermentation flask marked two required one and a half grams of Maseca Brand Corn Flour as the fermentation substrate, the fermentation flask marked three required one and a half grams of Carolina Biologicals Glucose as the fermentation substrate, and the fermentation flask marked four required one and a half grams of distilled water as the fermentation substrate.

The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.
In the short story, by Ethan Canin, “Star Food,” a boy named Dade is faced with struggles with his parents that have different points of views as his mother is an optimistic woman that wants Dade to keep dreaming. On the other hand, Dade’s father who is a realist wants Dade to carry the name and own Star Food after his father, he also wants Dade to work in store efficiently. They both wanted different things for his future, but everything changes when a poor, thieving woman enters their lives and steals from their store. The biggest question in “Star Food” is why Dade let the woman go. I believe Dade let the woman go because he felt like he wasn’t cut out for the life his father lived, and wanted to be more distinct than his strict father.
The phenomenon is more prevalent in low-income, racial and ethnic minority neighborhoods, as it were reported
Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
The B. Vulgaris samples were approximately 1cm3. They were kept the same size to ensure accurate results. A control test was conducted in distilled water to obtain a result to compare. The ethanol treatments were 40% and 70%. To prepare the solutions a 70% ethanol solution was used to make 40%.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
Is having junk food in school really such a bad idea? Does it obtain a value that some schools lack? Junk food was provided in school, before the health program came into place, banning it from schools around the country. It was proudly served and allowed in school, and also sold for many school fundraisers. Although some people might say that junk food can be unhealthy, schools should allow, or serve, some junk food because it will make the kids want to eat school lunches more, it will bring in more money to the school, and it will give the students the calories that they need.
Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules.
That 's 30 percent of the global total. The top countries most responsible for the plastic pollution issue are as following, China, The Philippines, Vietnam, Sri Lanka, Thailand, Egypt, Malaysia, Nigeria, and Bangladesh. What are we gonna do about it? Switch bag materials or don 't even provide bags just make the people bring their own bags and then they can continue to reuse them and then we won 't have the issue of plastic ending up in the ocean. Innocent animals we haven 't even discovered yet are dying because people can 't walk 10 feet to a trash can.
What is Processed Food? The term ‘processed food’ applies to any food that has been changed from its natural state in some way, either for safety reasons or convenience. Some foods need processing to make them safe, such as milk, which needs to be pasteurized to remove harmful bacteria. Other foods need processing to make them suitable for use, such as pressing seeds to make oil.
Resistant on implementing and installation of the new technology might force government to really impose such regulation and that they are always monitored by the regulatory board and also penalties are very serious matter. 3. Plastic manufacturing produces toxic because it composes several chemical that might endanger the living organisms in the water and can be harmful to humans and it is against the law of the Philippines if companies are not responsible with its wastes. III.
Obviously the development of producing plastic went to quick and people did not think of a unified and sustainable way of how to dispose the huge amount of plastic. Unfortunately many countries decided to dispose all the garbage into the ocean but also ship accidents are a reason why so much plastic accumulated in our ocean. Every year more than eight million tons of plastic waste leak into the ocean. A big issue nowadays is that most of the plastic which is produced in one year is used to make disposable items of packaging or other short lived products that are discarded within a year (Philosophical Transactions of The Royal Society, 2009).
Based on my data for my daily intake of foods, I would say that I live a pretty healthy life. I went over the food groups and calories, nutrients, food details and meal summary of my food diary and I thought it was interesting to look at all the little details of the different foods I ate throughout the day for breakfast, lunch, dinner and snacks. If I had to set 5 goals to improve my nutrition in what I eat and how I keep myself healthy I would have to say for the first one, exercise more, the second one choose healthier meal options, third one eat more throughout the day, fourth one choose healthier snacks, and for the last one do not eat when bored. I try to exercise as much as I can when I have free time, but it is sometimes hard to find some free time.
In most foods, microbial contaminations occur predominantly at the surface, meaning using edible films such as chitosan allows minimal space between the foods’ surface and its’ environment. However, the coating has weak mechanical properties, and is permeable for gas and water vapour. Blending chitosan with starch improves its mechanical properties and allows a better novel food preservative. ADVANTAGES: - As chitosan is the second most abundant carbohydrate after cellulose, it’s not unusual that its waste exceeds 25bn tonnes per year.
