我们以前的研究表明,γ-氨基丁酸(GABA)在厄尔的甜瓜是更集中在内部比外部的水果。在这里,GABA和抗氧化能力的胎盘组织的甜瓜,这被认为是废物,进行了评估,可能用作生物活性化合物的来源。GABA和相关物质的浓度在胎盘组织中显着高于果肉,而谷氨酸和糖的水平显着降低。两个位点的GAD活性无差异。此外,胎盘网站表现出高的抗氧化能力的基础上2,2-二苯基-1-苦肼和氧自由基的吸收能力的亲水性化合物测定相比,果肉,因为总酚和L-抗坏血酸的水平较高。因此,甜瓜的胎盘组织可用于开发功能性食品,这也将减少甜瓜加工过程中的残留量。
Our previous study revealed that gamma-aminobutyric acid (GABA) in Earl’s muskmelon is more concentrated in the inner than the outer parts of the fruit. Here, the GABA and antioxidant capacity of the placental tissue of muskmelon, which is considered waste, were evaluated for possible use as a source of bioactive compounds. The concentrations of GABA and related substances in the placental tissue were significantly higher than in the fleshed pulp, whereas glutamic acid and sugar levels were significantly lower. The two sites showed no difference in GAD activity. Furthermore, the placental site showed high antioxidant capacities based on 2,2-diphenyl-1-picrylhydrazyl and oxygen radical absorbance capacity for hydrophilic compounds assays compared with the fleshed pulp, because of the higher levels of total phenolic and L-ascorbic acids. Therefore, the placental tissue of muskmelons may be useful for developing functional foods, which would also reduce the amount of residues during muskmelon processing.
