Sand Pear Research Paper

2518 Words11 Pages

The edible portion of the sand pear (Pyrus pyrifolia L.) fruit contains good amounts of carbohydrates (11.9 gm), fiber (1 gm), minerals, vitamins and polyphenols. The pears can play important role in cardiovascular disease prevention because of they are good source of potassium and are free from sodium, cholesterol and fat. The pear fruit is a highly perishable commodity and can be preserved by canning and dehydration. The sand pear possesses attributes like grittiness, higher acidity and astringent taste and thus can be processed as candy. The pear candy can be prepared by combining the osmotic and convective dehydration at controlled conditions. The osmotic dehydration kinetics of pear slices was studied in sucrose solution having different …show more content…

(1983)

The adequacy of the model for the best fitting of experimental data was evaluated by obtaining the coefficient of determination R2 and least RMSE and percent mean relative deviation of modulus (E%) using following equations:
E(%)=100/N ∑_(i=1)^N▒[(Experimental value-predicted value)/(Experimental value)]
Chi Square=χ^2=∑_(i=1)^N▒[〖(Experimental value-predicted value)〗^2/((N-n))]
Where, n = no. of unknown and N= number of data points
RMSE=Root mean square error=∑_(i=1)^N▒[√(〖(Experimental value-predicted value)〗^2/N) ]
The nonlinear regression analysis was performed by using Statsoft Statistica (7.0.61.0 EN). RESULT AND DISCUSSION
The effect of all process variables including solution concentration, solution temperature and immersion time on mass transfer kinetics namely water loss and solute gain was investigated. The detailed description of effect of process variables on mass transfer kinetics and its modeling has been discussed as

    In the article "Cactus's at Risk" by Rebecca Katzman, it explains to us how cactus poaching is becoming more and more popular in the United States. The cactus's around are now in danger and the problem is becoming worse. The article says, "The sun goes down and a truck pulls up to a giant saguaro (sa-wah-ro) in the Sonoran Desert. Poachers wearing protective gloves dig up the cactus, wrap it in a carpet, and drive away." This evidence shows that now cactus poachers are snatching up cactus's and to stop it would be a very difficult task.

  • Peach Baskets Research Paper

    At the beginning, the game was played with peach baskets or 18 inch square boxes hanging on the balconies of the running tracks of most indoor facilities. During that time the height of the basket was set at 10 feet, which still is today. Apparently, the game has slowed down by the peach baskets and boxes since the ball had to be taken out from them after every goal, either by someone on the running track or by ladder. Heavy woven wire rims replaced the peach baskets first in 1892. Then, after a year, in 1893 cast iron rims were used.

    The predicted and experimental responses are compared in order to validate the model and to calculate the prediction error. The prediction error was found to be below 7% indicating that the observed responses were very close to the predicted values. Percentage prediction error is useful in constituting the validity of generated equations and describes how close the predicted responses to that of actual values. The values of <15 are desirable to have closeness of the predicted values with the actual values

  • Rhubarb Osmosis Lab Report

    Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

  • Essay On The Effect Of Temperature On Osmosis

    1159 Words  | 5 Pages

    Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick   Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.

    The Medicinal Properties of the Willow Tree Overview The willow tree has been used since ancient civilizations for its ornament, erosion control, timber, and especially its bark. The story of the willow tree dates to Hippocrates, 4000 BC, when people were advised to chew on the bark of a willow tree to lessen inflammation and reduce fever. The bark of the tree contains a compound called salicylic acid, which is a common ingredient in aspirin and is known for a multitude of medicinal effects ranging from something as simple as a pain-reliever to disease prevention. This paper focuses on the history of the willow tree, its anatomy, and its medicinal properties in relation to disease prevention.

The small plant seems to personify Mama’s stubborn nature in its intent on survival despite its close to death appearance. It also represents Mama’s dream that seems close to being crushed, yet never dies. As a whole, the plant is an extension of Mama’s character and an important symbol in the play.

  • Osmosis In A Potato Cell

    By using the same mass of potato slices and putting them in different concentration of solutions for a specific amount of time will tell us how the concentration changes the mass of the potato slice. Therefore changing the rate of osmosis. Hypothesis: I predict that, if the piece of potato was put into a solution that has a high concretion of sucrose then the potato slice would lose mass as it would lose water from its cells because the water is moving out of the cell from a high concentration to a low concentration of water through a semi- permeable membrane. The cell is hypotonic and the solution is hypertonic.

    This experiment is to investigate the relationship between solute concentration and the movement of water through semipermeable membrane by the process of osmosis. The purpose of this The Visking tubing apparatus establishes the osmosis procedure. The Visking tubing is a semipermeable membrane filled up with concentrated sucrose solution. The surface of the semipermeable membrane symbolizes the visking tubes and the mixture demonstrates the cytoplasm. If the Visking tube is absorbed in water, after a period of time, it will be have water inside water, this is because the water molecules can pass through the tubing, while the larger sugar molecules cannot diffuse out from the tubing because the size of sugar molecules do not allow it to go through the tubing.
