Centesimal and mineral composition of the fruit in Brazilian genotypes of feijoa (Acca sellowiana)

Abstract

This research was carried out to evaluate centesimal [dry matter (DM), ash, and crude contents of proteins (CP), fats (CFt) and fiber (CFb)] and mineral composition (Ca, Mg, N, P, K, Fe, Zn, Cu and Mn) of peel and flesh tissues of feijoa fruit (cultivars Alcântara, Mattos, Helena and Nonante, and accession 2316). The genotypes had, in the flesh, DM of 12.10-15.40%, ash of 0.33-0.40%, CP of 0.95-1.45%, CFt of 0.56-1.72%, and CFb of 1.39-2.43%, and in the peel DM of 12.8-17.27%, ash of 0.30-1.49%, CP of 0.56-0.88%, CFt of 0.57-0.90%, and CFb of 2.54-3.98%. The contents of Ca, Mg, K, N and P in the peel were 96-116, 20-30, 1588-3635, 1096-1643 and 68-83 mg kg-1 FW, respectively, and in the flesh were 56-92, 17-29, 1358-2917, 2017-3384 and 255-374 mg kg-1 FW, respectively. Among the micronutrients, Fe had the highest content in peel and flesh tissues (~3.5 mg kg-1 FW). The results show that feijoa fruit represent a dietary source of CP, CFt and CFb, as well as of minerals, especially of P and N in the flesh, and of K and Fe in the peel and flesh tissues.

“…Já os micronutrientes em maiores concentrações foram Fe (15,10 mg/kg) e Mn (6,65 mg/kg). Esses resultados estão de acordo com os apresentados por Amarante et al (2019) para a casca in natura de diferentes genótipos de feijoa. Diante da sua composição mineral, a FRF se mostra como uma importante e potencial fonte de elementos essenciais.…”

“…A feijoa (Acca sellowiana), também conhecida como goiaba-serrana, é uma fruta da família Myrtaceae e nativa da América do Sul (sul do Brasil, norte da Argentina e oeste do Paraguai e Uruguai) (Arioli et al, 2018). Apesar de ser pouco conhecida no Brasil, é uma fruta cultivada em várias regiões do mundo e apreciada pelos seus sabor e aroma únicos (Amarante et al, 2019). Na Nova Zelândia e na Austrália seu cultivo já é popular, sendo exportada como fruta fresca ou produtos industrializados como sucos, bebidas alcoólicas, geleias, compotas, doces e outros (González-García et al, 2017).…”

Characterisation and pre-selection of Acca sellowiana genotypes by multivariate analysis

“…However, this fruit tree has high economic, commercial and food potential, especially in countries, such as France, Arzebaijan, Israel, the United States of America, Chile, Colombia, Iran and New Zealand (Thorp & Bieleski, 2002;Santos et al, 2011;Karami et al, 2013;Pasquariello et al, 2015;Rasekh et al, 2021), and its cultivation success is attributed to the peculiar flavour of the fruit (Nodari & Guerra, 2017), nutraceutical components, and antimicrobial activity (Basile et al, 1997;Vuotto et al, 2000;Pasquariello et al, 2015;Phan et al, 2019). The fruit is rich in proteins, fibre, vitamin C, essential oils and minerals, such as potassium, phosphorus and iron (Zhu, 2018;Phan et al, 2019;Amarante et al, 2019). Feijoa fruit contains high amounts of bioflavonoids and polyphenols, such as catechin, leucoanthocyanins, proanthocyanidins and naphthoquinones, which confer many health benefits to the fruit (Weston, 2010;Karami et al, 2013;Zhu, 2018;Ielpo et al, 2000).…”
