2018年3月15日 · Ordinary citrus fruit as sweet oranges, mandarins, lemons and grapefruits are considered to be mature for fresh consumption when their external coloration, juice content and soluble solids: acidity ratio and other internal constituents reached to a minimum standard of visual acceptance or palatability.

Citrus fruit production and quality are influenced by many factors, including climatic conditions and produc-tion practices. In subtropical climates, the temperature usually falls below 70°F for several months dur-ing winter. This period of cool temperatures causes growth to cease and citrus trees to become dormant for about three months.

2024年3月19日 · Understanding these properties enables informed decision-making for producers, distributors, and consumers, ensuring that fruits align with desired sweetness, color, and texture preferences. Moreover, it helps identify optimal harvest times and postharvest treatments to maintain fruit quality during transportation and storage.

main commercial maturity indicator of citrus fruit internal quality. A 10:1 TSS:acidity ratio means 10% of TSS and 1% acidity or 8% of TSS and 0.8% of acidity.

2024年3月19日 · All the nutritional and organoleptic attributes of citrus fruits are contributed by carbohydrates, water, organic acids, vitamins, minerals, dietary fiber, and bioactive compounds. For instance, total soluble solids (TSS) and titratable acidity of citrus juice are attributed to simple sugars and organic acids, respectively.

2017年12月11日 · The regulation of citric acid metabolism during fruit ripening has a major impact on the production of high-quality fruit. The impact of citric acid on organoleptic fruit quality attributes, fruit storage performance and the synthesis of several secondary metabolites has led to an exponential increase in research efforts during the last two ...

2024年2月10日 · Here, we performed transcriptome analysis of five pairs of acidic and acidless variety fruits from kumquat (Citrus crassifolia), lemon (C. limon), pummelo (C. maxima), mandarin (C. reticulata), and sweet orange (C. sinensis) to investigate the common and specific genes related to citric acid accumulation in these citrus species.

2023年5月28日 · While the content of soluble sugars in citrus fruit is high, the content of organic acid in the fruit has become the key factor affecting the quality of citrus fruit. In the early-ripening variety Wenzhou mandarin, citric and malic acid increased at the same rate in the initial stage of fruit growth and development, and their contents were ...

3 天之前 · Citric acid, the predominant organic acid in citrus fruit, directly influences its edible quality and economic value. While the transcriptional regulatory mechanisms of citric acid metabolism have been extensively studied, the understanding about the transcriptional and epigenetic co-regulation mechanisms is limited.

2014年9月1日 · Coloration, soluble solids, acidity and juice content are relevant parameters considered for harvest decision; however, relative importance depends on the citrus variety considered and the...
