番茄(Lycpers sice esculentum Mill.)水果，简历。对乙烯和二氧化碳产生的五个成熟阶段进行了分析。从同一水果制备的匀浆用于颜色、风味挥发物、糖和有机酸的测定。这些化合物水平的变化与更年期乙烯产生的模式进行了比较。在测定的风味挥发物中，只有丁香酚在两个品种的成熟过程中下降，而1-戊烯-3-酮在‘阳光’番茄中下降。乙醇和反式-2-反式-4-十二烯含量没有随果实成熟而变化或波动，而所有其他挥发性物质(顺-3-己烯醇、乙醛、顺-3-己烯醛、反式-2-己烯醛、己烯醛丙酮、6-甲基-5-庚烯-2-酮、香叶内酮和2-异丁基噻唑)浓度升高，在转色、粉红色或红色成熟期达到峰值。一些挥发性物质的合成与跃变期的乙烯、二氧化碳和番茄红素的产生同步进行。红期‘日光’果实除乙醇和己醛外，其余风味成分含量均高于‘阳光’。不同品种间的有机酸水平没有差异，但‘日光’含糖量较高。酸和糖水平的变化与更年期乙烯或二氧化碳的产生没有时间上的关系。
Tomato (Lycopersicon esculentum Mill.) fruit, cvs. Sunny and Solar Set, were analyzed at five ripening stages for ethylene and CO2 production. Homogenates from the same fruit were prepared for determination of color, flavor volatiles, sugars, and organic acids. Changes in the levels of these compounds were compared to the pattern of climacteric ethylene production. Of the flavor volatiles measured, only eugenol decreased during ripening in both cultivars and 1-penten-3-one in 'Sunny' tomatoes. Ethanol and trans-2-trans-4-decadienal levels showed no change or fluctuated as the fruit ripened while all other volatiles measured (cis-3-hexenol, acetaldehyde, cis-3-hexenal, trans-2-hexenal, hexenal acetone, 6-methyl-5-hepten-2-one, geranylacetone, and 2-isobutylthiazole) increased in concentration, peaking in the turning, pink, or red stage of maturity. Synthesis of some volatile compounds occurred simultaneously with that of climacteric ethylene, CO2 and lycopene production. 'Solar Set' fruit exhibited higher levels than 'Sunny' of all flavor components except ethanol and hexanal in the red stage. There were no differences in organic acid levels between the cultivars; however, 'Solar Set' had higher levels of sugars. Changes in acid and sugar levels showed no temporal relationship to climacteric ethylene or CO2 production.
