Some selected physical characteristics of the banana such as mass, true volume, bulk density, true density, geometric mean diameter, surface area etc and their statistics such as mean, standard deviation (SD) and standard error (SE) were presented in Tab. 1. These two statistics measure the consistency of the data.

Standard deviation measures the degree to which the value of the individual sample differ from the sample mean. More number of replication decreases the standard deviation value. From the table 1, it is observed that standard deviation is ranging from 0.02 to 9.86 and found that the data are consistence within the replicates. Standard error estimated th...

A fruit’s heat and lineage are very dependent on growing conditions it is in. Soil, rainfall, and climate are factors that would have the potential to alter a plant. The author questions rather the Naga King Chili would be hotter if it were grown in an area with different growing conditions. Even in regions just next to Nagaland, it is possib...
I don’t think that calculating average, in this case, is all that common? I cannot find average types of fruit. I cannot apply numerical techniques to the qualitative data. We say that it is a factor because the values of variables have qualitative values. Factors are describing the type of fruits and are represented by words and letters (Yakir, 2011). Therefore, the colors would be coded as factors.

Composition and textural attributes play a vital role in popularizing a food product. Texture and flavour appear to be the most important attributes for the consumer (Stow, 1995). Texture profile analysis (TPA) is a technique commonly used in industry for the evaluation of food textural behavior, as it can give an indication of sensory properties (Burey etal., 2009). TPA is useful for gel texture analysis because of the textural parameters
Seven 250ml beakers were obtained and labeled with the following molarity of sucrose solutions: 0 M (pure water), 0.1 M, 0.2 M, 0.3 M, 0.4M, 0.5 M, and 0.6 M. 100 ml of each solution was added to the appropriate beaker. Then, a cork borer was used to obtain a potato cylinder from the potato. It was pushed through the longest axis of the potato. A punch was used to push the potato cylinder out of the cork borer. Enough potato cylinder was obtained to provide 7 1 cm sections. Care was taken to ensure the potato skin was cut off. Each potato piece was blotted dry with a paper towel. A plastic weight boat was placed on a scale, tared and set to measure in grams. Each potato piece was weighed, and the weight was recorded in a table. After weighing,
Seven evenly cut pieces of potato cylinder were incubating in distilled water, 0.1M, 0.2M, 0.3M, 0.4M, 0.5M, and 0.6M sucrose solutions for 1.3 hours to test the effect of osmolarity on the potato tuber cell. The pieces were weighed and compared to the weight of the potato before the incubation. Each final weight of the potato cylinder decreased as the concentrations of sucrose became higher, and the change in weight of the potato decreased in the higher concentrations of sucrose. Within the incubation period, the water
Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried, weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated.
The biggest weakness was the fact that this experiment was not conducted several times to highlight the systematic errors and again, eliminate any random errors that can be avoided. Only a small range of sample size was taken and therefore, different concentrations outside the 0%-10% glucose solution should be tested to have a better understanding of the trend. Drying of the potato varies and this can cause a major effect on the after mass of potato cores.
The untreated and lime treated maize varieties were pulverized, sieved using a BS 60 mesh sieve and evaluated for chemical constituents such as moisture content of the sample estimated by hot air oven method, protein was determined by available nitrogen in the sample by microkjeldhal method in Kjel plus (Pelican equipment, India), fat estimated by soxhlet extraction
For cassava root, r2 for predicting individual AA from CP content was generally low and was greater than 20% only for TAA and valine. Also, r2 for predicting individual AA from leaf was 25% for TAA while that of peel was above 70% for histidine and threonine. Weak relationship observed among the CP, TAA and TIAA in this study might be due to their percentage proportion and changes in protein level as a result of development stage and environment (Howelar,
These symptoms mainly develop during fruit ripening after cold storage, and the problem is not noticed until the fruit reaches customers (Bruhn et al.,1991; Crisosto et al., 1995). Thus, postharvest treatments that can alleviate chilling injury and extend shelf-life of pineapple fruits are urgently needed. CI visual symptoms develop within 1 or 2 weeks when fruit are stored at 2–5 ◦C compared to 3 weeks or more at 0 ◦C (Anderson, 1979; Lill et al., 1989;Crisosto et al., 1999a). At present, wax (edible coatings) have been used as an effective technology to increase the quality of postharvest fruits and vegetables(Qiuping and Wenshui, 2007; Fan et al., 2009; Tzoumaki et al., 2009; Tietel et al., 2010). Edible coatings may be composed of polysaccharides, proteins, lipids or a blendof these compounds (Li and Barth, 1998; Park et al., 1994; Guilbert et al., 1996;Mahmoud and Savello, 1992; Arvanitoyannis and Gorris, 1999). These coatings may retard ripening and increase shelf life of coated produce, without

(2012a) investigated effects of different pomegranate juice extraction methods on quality and stability of pomegranate juice were evaluated. A Hand press method, mechanical extraction using screw type hand juicer and electrically operated fruit juicer and machine extraction using electrically operated hydraulic basket press methods were used for extraction from manually separated arils of pomegranate fruit cv. Bhagwa. An extracted juice was analyzed for physicochemical and sensorial parameters like juice recovery, specific gravity, pH, TSS, acidity, sugars, phenols, anthocyanins, antioxidant activity, colour, flavour, taste and overall acceptability. Microbial limit tests were also carried out. Screw type hand fruit juicer with fiber molded crusher gave highest per cent juice recovery on fruit and aril weight basis. It also recorded maximum anthocyanin content (85.815mg/100 g) and sugars (16.818 per cent) in juice. Highest overall acceptability score (8.607) with low microbial population (7.95 x 103 cfu/ml) was observed with this
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
