“…Measurement of total soluble solids (TSS) and pH were carried out at 25 °C using a SMART-1 Digital Benchtop refractometer (Atago, USA) and a HI 5521 pH meter (Hanna, Instruments, USA), respectively. Titratable acidity (TA) was measured through the titration of fruit juice with 0.1 N NaOH, until achieving the neutralization by phenolphthalein indicator (Mkhathini et al, 2017). The results were expressed as a percentage of citric acid equivalents Maturity index was calculated as the TSS/TA ratio (Navarro Acosta et al, 2010;Mkhathini et al, 2017).…”

The ripening of fruits is a determinant factor on the composition of phytochemical compounds such as phenolic compounds. In this study the phenolic profile of quince fruits was determined as a function of its maturity index. Based on the total soluble solids (TSS) and the acidity (TA) of the fruits, four maturity indexes were established (12.55, 14.56, 21.86 and 24.77), using the ratio of TSS/TA. The phenolic profile of quince fruits with different maturity indexes were obtained by a reversed-phase HPLC-DAD and HPLC-DAD/MS. A PCA loading plot was generated to explain the relationship between physicochemical parameters and the phenolic compounds. The phenolic compounds identified in the quince fruits were 3-0-caffeoylquinic acid, catechin, 4-0-caffeoylquinic acid, 5-0-caffeoylquinic acid, coumaric acid, quercetin-3-0-rutinoside and quercetin-3-0-glycosides. The maturity index increase caused in general a reduction of phenolic compounds, these compounds were also influenced by pH and acidity of fruits. Quince is a valuable source of natural phenolic antioxidants, and can be used as raw material to elaborate diverse food products, providing important functional properties.

Successful journal submissions follow a predictable format and vary in length of between 5000 and 6500 words, including references. Formulating well-defined, tight research questions that contribute to an open aspect of the extension literature is essential for success. A good question makes it easier to identify appropriate analytical techniques and provide a logical structure to the results section. The most frequently encountered problems with unsuccessful submissions to this journal are the absence of a clear question, flawed research design, papers that are too short and present only a superficial inadequate analysis of descriptive statistics and papers that are front-heavy with an underweight disappointing results section. These problems are easily corrected by closely adhering to academic writing conventions and good research design, which explains why experienced authors have a better chance of success than novices.
