Effect of different concentrations of pulverized mesocarp of Citrus paradisi Macf. on the bromatological characteristics of spray‐dried lemon juice powder

Abstract

The aim of this research was to evaluate the effect of different concentrations of pulverized mesocarp of Citrus paradisi Macf. as a drying aid on the bromatological characteristics and yield of spray‐dried lemon juice powder. Five concentrations of grapefruit mesocarp encapsulant (0.4, 0.8, 1.2, 1.6, and 2.0% (w / w)) and maltodextrin DE 10 (1.2%, w / w) were evaluated as encapsulant agents. The highest yield (46.76%) was obtained with 1.2% of grapefruit encapsulant. Water activity and ash content were inversely proportional to the added encapsulant concentration. The highest moisture value was obtained with 0.4% and the highest soluble solids with 2.0%. For all treatments, the pH level did not change, except at 0.4% (it was lower). The concentrations of the encapsulants significantly affected the evaluated characteristics, except for the proteins.

Production of mango powder by spray drying and cast-tape drying

“…Análisis bromatológico. Se resalta que, el contenido de proteína cruda de la MPUA (4.2 g/100 g bs) fue mayor a lo reportado por Alcantara et al (2018), en polvo de limón a diferentes concentraciones de maltodextrina (1.90 -2.12 g/100 g bs), por otro lado, el contenido de grasa de MPUA fue de <0.48 g/100 g bs (aporte proveniente de los aceites presentes en la semilla en la MPUA). En uchuva se ha reportado 1.9 g de aceite/100 g bs , lo cual representa un valor superior a la MPUA.…”

“…En uchuva se ha reportado 1.9 g de aceite/100 g bs , lo cual representa un valor superior a la MPUA. El contenido de cenizas de MPUA fue de 3.37 g/100 g bs, encontrándose en el rango de polvo aglomerado de leche de soya (3.1 -5.0 g/100 bs) (Jinapong et al, 2008), mayor al polvo aglomerado de champiñón común (2 g/100 g bs) , menor al polvo de limón (14.6 -16.1 g/100 g bs) (Alcantara et al, 2018) y al polvo de subproductos de residuos de naranja para ser utilizado como material de pared en SA (4.3 ± 0.1 g/100 g) (Kaderides & Goula, 2017). La fibra dietaria de MPUA fue de 32.0 g/100 g bs, la cual proviene principalmente de la cascarilla de la semilla de uchuva, siendo este valor inferior al reportado por de Moraes Crizel et al ( 2013), en fibra de naranja (mezcla de cáscara, pulpa y semillas y cáscaras) (46.2 ± 2.3 g/100 g bs).…”

Evaluation of the Essential Oil of &lt;i&gt;Citrus paradisi&lt;/i&gt; as an Alternative Treatment against &lt;i&gt;Candida albicans&lt;/i&gt;

“…The presence of compounds in the essential oil of Citrus paradisi has been reported, identifying monoterpenic hydrocarbons as limonene (94.8%) was the most abundant, α-terpinene (1.8%), α-pinene (0.5%) and sabinene (0.4%),β-pinene, γ-terpinene and myrcene (<0.05%), sesquiterpenic hydrocarbons (0.3%), aliphatic aldehydes such as octanal (0.4%), decanal (0.3%), dodecanal (0.1%) and tetradecenal, alcohols such as linalol, (E)-p-menthadien-1-ol and α-terpineol (0.1%), esters (0.4%) and nootkatone (0.1%) [30]; the results of this study agree with the major compounds identified in the oil. Other authors have referred to the presence of flavonoids, amino acids, phenolic and vitamins, alkaloids, flavonoids, steroids, terpenoids, saponins, cardiac glycosides and sugars in C. paradisi oil [31] [32]. Terpenes, α-pinene, vinyl sesquiterpene [16], sabinene, ocimene, linalool, β-pinene, limonene, β-myrcene, and terpinen-4-ol have also been reported in the essential oil by gas chromatogram [20].…”

Anti‐inflammatory properties of an aldehydes‐enriched fraction of grapefruit essential oil

“…Interestingly, it has been shown that pulverized grapefruit ( C. paradisi Macf.) mesocarp at different doses (0.4%, 0.8%, 1.2%, 1.6%, and 2.0%) significantly influenced the composition of the encapsulated lemon juice, except the protein content (Alcantara Marte et al., 2018). In addition, the majority of the available data indicate high content in phenols and flavonoids as a source of oxidative protection, while, to the best of our knowledge, this is the first report showing anti‐inflammatory effects of GEO_SD.…”
