Cassava starch was mixed with water‚ cornstarch and cooking oil INTRODUCTION There is an increasing demand for plastic‚ from the highly technological fields of electronics‚ fiber optics‚ and pharmaceuticals to the basic necessities such as sandwich wrappers and garbage bags. This high demand for plastics‚ however‚ has been a major contributor to the world’s present garbage problems. Because plastics are made of polymers‚ starch is a very favorable

BIOPLASTICS Bioplastics are a form of plastics derived from renewable biomass sources‚ such as vegetable fats and oils‚ corn starch‚ pea starch or microbiota. There are a variety of materials bioplastics that can be composed of‚ including: starches‚ cellulose‚ or other biopolymers. APPLICATIONS OF BIOPLASTICS Biodegradable bioplastics are used for disposable items‚ such as packaging and catering items (crockery‚ cutlery‚ pots‚ bowls and straws). They are also often used for bags‚ trays‚ containers

the lab experiment‚ it was predicted that whipping cream‚ soy milk‚ and the flour solution would all contain proteins. Looking back at the collected observations it can be concluded that the hypothesized statements were all deemed accurate. However‚ corn syrup was the only substance that did not test positive for proteins. This abnormality was researched‚ and it is now clear why only three out of the four substances tested positive for proteins. To start‚ it was hypothesized that whipping cream would

especially in regards to corn. Everyone loves a sweet‚ tender "corn on the cob" in the summer time. Although this piece of food is delicious‚ it has been through numerous mutations to get to what is in modern society. By the 1400s‚ corn was a staple in the diet of those in Mexico and the Americas according to Jo Robinson’ article (Robinson). The corn in the early days was to be known as Teosinte. It contained‚ little‚ sugar‚ a lot of starch and protein compared to the corn we see today‚ which is of

isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological responses of the pill pub are altered in response to distinctive conditions in its environment

This lab is broken down into four different sections‚ the Benedict’s test for reducing sugars‚ the iodine test for the presence of starch‚ the Sudan III test for fatty acids‚ and the Biuret test for amino groups present in proteins. The last part of this lab takes an unknown substance and by the four tests‚ determine what the substance is. BENEDICT’S TEST Introduction: Monosaccharides

Used the same pipette that I used to mix the dialysis bag solution‚ removing two mL of that solution and placed it in a clean beaker. That sample served as my positive control for glucose and starch. Dipped one of the glucose test strips into the two mL of glucose/starch solution in the third beaker. After one minute had passed‚ recorded
