“…At harvest, fruit harvested late had a higher starch index (lower starch content), higher soluble solids content, and lower flesh firmness and acidity than fruit harvested early in both years (Table 1). These characteristics of late-harvested fruit confer greater sensori- After storage, the fruit harvested early maintained greater flesh firmness and acidity in proportion to the differences observed at harvest in both years (Table 2), as reported in other studies for 'Gala' (ARGENTA; MONDARDO, 1994) and 'Fuji' apples (VIEIRA et al, 2018). Similar to the results observed at harvest, the average of the three harvests shows that flesh firmness and acidity were higher in 2008 compared to 2009.…”

This study aimed to analyze the effect of harvest date on ‘Fuji Suprema’ apple quality, productivity, and economic profitability at harvest and after storage. Apples were harvested at the beginning of the commercial harvest window (H1), ten days after H1 (H2), and 22 days after H1 (H3) in the 2008 and 2009 growing seasons. A total of six samples with ~400 kg of fruit (~2,900 apples) each were picked at each growing season and harvest date, which were assessed at harvest (six subsamples of 100 fruit) and after 250 days of controlled atmosphere storage at 0.8 °C. The economic analysis considered fixed and variable production costs in the orchard and postharvest practices and the productivity of packaged apples (pack-out). Early harvested (H1) apples had greater flesh firmness, acidity, and lower soluble solids content than late-harvested apples (H3), both at harvest and after storage. Delaying harvest by 22 days increased the production by 10.2% due to increased fruit size but reduced the production by 3.6% due to severe sunburn and pre-harvest decay incidence. Late harvest also increased production losses due to decay by 4.4% and 10.9% during storage and shelf, respectively, but reduced production losses due to superficial scald by 17.1 to 22.7%. The net revenue (R$ ha-1) is higher for apples harvested late (H3, flesh firmness of 15.6 lb and starch index of 7.1) than for apples harvested early (H1 and H2) when the fruit is marketed soon after harvest (between April and May). However, for apples marketed after long-term storage, economic profitability is maximum when harvested at an intermediate maturity stage (H2, flesh firmness of 16.4 lb and starch index of 6).

“…High DM concentration indicates a high proportion of dry matter in the fruit and is associated with better eating quality and longer shelf life. Conversely, low DM concentration indicates lower-quality fruit with a shorter shelf life [210][211][212].…”

Spectroscopic methods deliver a valuable non-destructive analytical tool that provides simultaneous qualitative and quantitative characterization of various samples. Apples belong to the world’s most consumed crops and with the current challenges of climate change and human impacts on the environment, maintaining high-quality apple production has become critical. This review comprehensively analyzes the application of spectroscopy in near-infrared (NIR) and visible (Vis) regions, which not only show particular potential in evaluating the quality parameters of apples but also in optimizing their production and supply routines. This includes the assessment of the external and internal characteristics such as color, size, shape, surface defects, soluble solids content (SSC), total titratable acidity (TA), firmness, starch pattern index (SPI), total dry matter concentration (DM), and nutritional value. The review also summarizes various techniques and approaches used in Vis/NIR studies of apples, such as authenticity, origin, identification, adulteration, and quality control. Optical sensors and associated methods offer a wide suite of solutions readily addressing the main needs of the industry in practical routines as well, e.g., efficient sorting and grading of apples based on sweetness and other quality parameters, facilitating quality control throughout the production and supply chain. This review also evaluates ongoing development trends in the application of handheld and portable instruments operating in the Vis/NIR and NIR spectral regions for apple quality control. The use of these technologies can enhance apple crop quality, maintain competitiveness, and meet the demands of consumers, making them a crucial topic in the apple industry. The focal point of this review is placed on the literature published in the last five years, with the exceptions of seminal works that have played a critical role in shaping the field or representative studies that highlight the progress made in specific areas.

“…In addition to the variations in the concentration of bioactive compounds and fruit quality parameters caused by seasonal effects, fruit maturity also plays an important role in determining the quality, sensory attributes and biological functions of plant‐based food products (Kader, 1999; Pinillos et al ., 2016; Vieira et al ., 2018; Aubert et al ., 2021). Therefore, harvesting KP fruit at the appropriate maturity is a key factor to ensure that the fruit fulfils the requirements for optimum compositional levels and to maximise the accumulation of bioactive compounds.…”

This study reports changes in the concentrations of important health-related bioactive compounds (vitamin C and ellagic acid) and morphology of wild harvested Kakadu plum fruits that were collected during three harvest seasons and four maturities. The results showed that fruit weight increased, whereas fruit length and width changed slightly with the advance in maturity. Vitamin C increased up to 20 folds (from 1.2 to 21.2% dry weight [DW]) from immature to mature stage, whereas ellagic acid decreased approximately three times (from 6.5 to 2.1% DW). Similar trends were observed over the three harvest seasons studied. A positive correlation between fruit weight and vitamin C, whereas a negative correlation with ellagic acid was observed, indicating that maturity plays an important role in contributing to the variation of ellagic acid and vitamin C. Season also had an effect and showed the influences of rainfall, temperature and solar exposure on the biosynthesis of vitamin C and ellagic acid.
