Apr 10, 2022 The highest polyphenol content was 417.7 mg GAE/100 g db in sun-dried samples, while the lowest was 207.9 mg GAE/100 g db in oven-dried samples. In our study, the range of TPCs in raisins was 332.7 to 659.6 mg GAE/g db, which is higher than the range reported by Qin et al. [ 39 ], Meng et al. [ 41 ], Ouchemoukh et al. [ 45 ] and Zemni et al ...

Aug 10, 2011 Fruits have a low pH that is usually below 4.5. This means that pasteurization inactivates harmful enzymes such as pectinesterase and polygalacturonase by applying the required temperature for a relatively short time. In contrast, milk, which has a higher pH, requires more severe heat treatment to inactive the pathogenic bacteria and requires ...

Feb 24, 2022 The water activity (aw) values of apple chip samples dried in the oven ranged from 0.544 to 0.650, while for the samples dried in the dehydrator, aw values were between 0.374 and 0.426. During the storage, the pH of apple chips varied very little, while titratable acidity increased for all samples.

Jun 07, 2017 K w varies with the temperature. For example, at 25 C, K w = 1.04 10 −14 but at 100 C, K w = 58.2 10 −14. The above concept of K w leads to the question of what the [H 3 O +] and [OH −] are in pure water.Experimentation has revealed that the [H 3 O +] is approximately 1.0 l0 −7 M, as is that of the [OH −] at 25 C.Because the concentrations of these ions are …

May 11, 2020 pH and Brix Analysis. The pH values were determined for the fresh and freeze dried black chokeberry samples at room temperature by using a pH meter (6173, Jenco, USA) and primarily calibrated with two-point using buffers at pH = 7.0 and 4.0. The level of sugars Brix was determined with a digital refractometer (MA871, Milwaukee, Romania) .

Sep 13, 2017 Brix scale is commonly used for total sugar content measurement for any substance. If a solution has 10 degrees Brix, that means that it contains 10 grams of solid compounds for every 100 grams of solution. Or, in other words, if we are talking about sugar concentration, the content of sugar is 10 grams and the content of water is 90 grams.
