| titleOfInvention | How to measure freshness of fresh food |
| abstract | (57) [Summary] [Purpose] When measuring the freshness of fresh food, it is easy to use the sample solution as the neutralization point when adjusting the sample solution, and it is possible to find the neutralization point without using test paper. Suggest possible ways. The objective is to provide a highly practical method that simplifies measurement and enables easy measurement in markets and ports. . [Structure] Add a liquid extract to the sample Add 2 CO 3 to neutralize and filter. Pass the filtrate through a column packed with resin. Flush the column with deionized water. Next, the first eluate is passed through to obtain a first fractionated liquid. Then, the second eluate is passed through to obtain a second fractionated liquid. The absorbance at 250 nm of each of the fractions was measured, and the value was used to calculate a K value, which was used as an index of freshness. |
