本研究确定了澳大利亚种植的费约（Acca sellowiana）的化学成分，生物活性化合物和生物学特性，包括整个水果与果皮，果皮和果肉，以评估这种新兴的亚热带水果的营养品质和抗菌活性。多酚类化合物和维生素的测定UHPLC-PDA-MS/MS，显示的feijoa水果不仅含有大量的抗氧化剂类黄酮，但也是一个有价值的来源，维生素C（63毫克/100克FW（鲜重））和泛酸（0.2毫克/100克FW）。Feijoa水果也是膳食纤维（6.8 g/100 g FW）和钾（255 mg/100 g FW）的良好来源。果皮中抗氧化剂类黄酮和维生素C含量显著高于果肉（p < 0.05）。这很可能是观察到果皮提取物对广泛的食品腐败微生物具有强抗菌活性的原因。食用费约果可以提供大量的生物活性化合物，如维生素C，类黄酮和纤维，因此，可能有助于健康饮食。此外，feijoa皮作为天然食品坚持剂的潜在用途需要在后续研究中进行调查。
The present study determined the chemical composition, bioactive compounds and biological properties of Australian grown feijoa (Acca sellowiana), including whole fruit with peel, fruit peel and pulp, in order to assess the nutritional quality and antimicrobial activity of this emerging subtropical fruit. Polyphenolic compounds and vitamins were determined by UHPLC-PDA-MS/MS, showing that the feijoa fruit not only contains high amounts of antioxidant flavonoids, but is also a valuable source of vitamin C (63 mg/100 g FW (fresh weight)) and pantothenic acid (0.2 mg/100 g FW). Feijoa fruit is also a good source of dietary fibre (6.8 g/100 g FW) and potassium (255 mg/100 g FW). The edible fruit peel possesses significantly (p < 0.05) higher amounts of antioxidant flavonoids and vitamin C than the fruit pulp. This is most likely the reason for the observed strong antimicrobial activity of the peel-extracts against a wide-range of food-spoilage microorganism. The consumption of feijoa fruit can deliver a considerable amount of bioactive compounds such as vitamin C, flavonoids and fibre, and therefore, may contribute to a healthy diet. Furthermore, the potential use of feijoa-peel as a natural food perseverative needs to be investigated in follow-up studies.
