Disadvantages Of Biocolors
4. Biocolors: The New Generation Additives4 Manisha Parmar and Urmila Gupta Phutela Abstract This research paper includes brief introduction about biocolors which can be classified into three main classes: natural colors, browning colors and additives. Biocolors have bicolorants as their coloring agent which is obtained from biological source. Microbial sources of natural colorants are explained which are considered as an important source of the natural pigment for coloring foods. Biocolors as additive can be used in various industries as in pharmaceutical industry, textile industry, dairy industry etc. Limitation of technology is the major problem for biocolor production from microbes. 5.

Natural dyes are preferred due to less environmental pollution. Dyeing performance in terms of color parameters (K/S, L*, a*, b* and ΔE), and fastness properties (wash, perspiration, and light fastness) are studied and the samples show high tensile strength, high color strength, and high fastness properties. These results will be helpfull for industrial application with the production of a natural dye as an inexpensive source from banana leaves as a by-product. Another objective of this work is to increase the production of eco-textile garments. 7. Herbal Ink: Safe, Easy and Ecofriendly Alternative7 Powar P. V, Lagad S B, Ambikar R.B, Sharma P. H. Abstract This research paper is about preparation of four herbal inks from different biological sources such as Beta valgaris (Beet Root) Chenopodiaceae, Citrus limonene (Citrus peel) family Rutaceae, Pentas lanceolata (Butterfly Flow petals) family Rubiaceae , Bauhinia purpurea (Butterfly tree) family Caesalpiniaceae etc. The prepared herbal inks is evaluated for several parameter such as Color, Odour, Taste, Brightness, Drying time , Flow ability, Non-clogging nature, Viscosity, Permanency of color, Stability. All inks were found to edible, safe, easy to prepare and stable. 8. Natural dye yielding plants in India8 S.B.Gokhale, A.U.Tatiya, S.R.Bakliwal and R.A.Fursule …show more content…
Thus making everyone to think about natural sources of coloring, Which have numerous advantages over synthetic dyes like less pollution generation in the environment and having less risk to human health. There is currently a demand for natural products in a niche market that could be expanded. A large number of shades suitable for the dyeing industry can be produced from natural dyes . According to this paper greater emphasis on using natural dyes in the textile industry could make a valuable contribution to environmental sustainability in the 21st century. More research is required to develop the market to its full
Procion Red Dye Lab Report
1454 Words | 6 PagesFor this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.

Mcgraw Hill Higher Education: Natural Selection-Virtual Lab
877 Words | 4 PagesAfter putting my organisms in an environment, the organisms with the color that best blended with the environment’s color would increase in numbers. Whereas, organisms with a dissimilar or opposite color to the environment would die-off over time. The reason why organisms that could better blend in with the environment flourished, while the organisms who stood out in the environment died is because of natural selection. The organism that could better blend in would be harder for predators to find, thus increasing its chances of living and reproducing. While the organisms that stood out would have a higher chance of being eaten or

509 Words | 3 PagesDue to the growing popularity of processed foods and the nation 's abysmal knowledge of them, writer Brian Rohrig argues that food coloring is an important attribute in the foods we eat in his article “Eating with your Eyes: The Chemistry of Food Colorings”. The author uses reasons, evidence, and effective word choice about how what makes a good food coloring, the best sources of natural food coloring and the benefits of synthetic food coloring to strengthen the logic and persuasiveness of his argument. Rohrig 's argument is also furthered when he appeals to the emotions of the reader. By referring the future, it causes the reader to think more in-depth about food coloring and how it may affect the future.
Protein Supplements Vs Starch Essay
885 Words | 4 PagesProteins have an important role in the body and must be ingested on a regular basis. They provide the body with the capacity to repair skeletal muscle tissue and to synthesize hormones and enzymes among other activities. In this experiment, we wanted to determine the organic molecules found in each brand of protein supplements and the amount of starch present. A protein supplement should contain amino acids and proteins; however, some supplements contain other molecules that are used as fillers, thus reducing the concentration of the protein.

The Pros And Cons Of Biophilic Design
736 Words | 3 Pages“Biophilic design is the deliberate attempt to translate an understanding of biophilia into the design of the built environment” (Kellert, 2008). It involves building and landscape design that enhance human well-being by fostering positive connections between people and natural environment. It is an innovative design approach that aims to maintain, enhance and restore the benefits of experiencing nature in the built environment. It starts by observing the effect of the mutual interaction between the natural and the built environment. The learned knowledge is then reflected onto the design and construction of the built environment.
