Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Gelatin has many applications in the food, pharmaceutical and cosmetic industries due to its technological and functional properties. By-products from fish cleaning are rich sources of collagen. The physical, chemical and rheological properties of gelatin or collagen depend on their sources as well as the extraction conditions. Response surface methodology (RSM) with three parameters was conducted to determine the optimum extraction conditions of gelatin from Caspian whitefish scale. A Box-Behnken design was used to study the combined effects of sodium hydroxide concentration (0.075-0.225 M), soaking time in sodium hydroxide solution (60-180 minute), and extraction temperature (30-50 C) were determined. Viscosity (cp), gel strength (g), L*, a*, and b* were chosen as responses. The results showed the optimum conditions were sodium hydroxide concentration 0.11 M, soaking time in sodium hydroxide solution of 116 minutes, and extraction temperature of 38 C. The predicted responses including viscosity, gel strength, L*, a*, and b* were 2.17 cP, 145 g, 6.03, 6.80, and 38.85 respectively. The response surface method was able to estimate the optimal conditions of extraction gelatin with high desirability (0.99).
