These experiences were in accordance with the results of the soluble solid content and titratable acid content, respectively.
This study systematically investigated the influence of different drying methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) on the main compositions of tangerine peels (moisture, soluble solid, reducing sugars, total sugar, crude fiber, titratable acid, ash content, and minerals), major functional components (total phenolic compounds, total flavonoids, hesperidin, synephrine, and vitamin C), and the antioxidant activity of the dried tangerine peels.
Titratable acid (TA) and total solid (TS) were analyzed for all frozen yogurt samples according to [17], and pH was determined by pH meter (MP 220, Metler Toledo, Greifensee, Switzerland).
Results showed that 50, 100 and 150 umol/L GNT significantly enhanced the intercellular CO2 concentration, net photosynthetic rate, stomatal conductance, transpiration rate, and chlorophyll, soluble sugar and titratable acid contents in G.
In their studies carried out to determine the effects of rootstock-variety interactions on fruit quality show that the amount of titratable acid changes significantly by variety but has almost no effect on pH value.
Total titratable acid (TTA) was estimated by titration with 0.1 M NaOH to neutralize all the total titratable protons.
Despite the above-mentioned influential parameters of the sour taste, the pH-values as well as the value of total titratable acid content does not permit a final statement on the taste of coffee, because the total acid content as referred to above is composed of a mixture of various acids.
Generally, the highest titratable acid concentrations were obtained in the packed juices (FOJ and COJ) and burukutu.
In common ringtail possums, an increase in N[[H.sub.4].sup.+] excretion of [approximately equal to]20 mmol[multiplied by][kg.sup.-1][multiplied by][d.sup.-1] above baseline was correlated with increased urine titratable acid and phosphate, and lowered urine pH (Foley 1992).
