Freeze-drying of acerola (Malpighia glabra L.)

Chemical Engineering and Processing: Process Intensification, 2007
Abstract Several quality parameters, such as water activity (aw), glass transition temperature (Tg), Vitamin C content, shrinkage and rehydration capacity were investigated for the freeze-drying of acerola fruits. The variation of temperature with time at different positions of the samples was measured during the freezing of samples, performed prior ...

Metabolic profiling and in vivo hepatoprotective activity ofMalpighiaglabraL. leaves

Journal of Food Biochemistry, 2020
Although Malpighia glabra Linn. fruits are well studied for their nutritional and medicinal prominence; little attention has been given to the leaves. Our study intends to investigate the leaves metabolic profile using Q-TOF LC/MS/MS (Quadrupole-Time-of-Flight-Liquid-Chromatography-Mass-Spectrometry), and to explore their in vivo hepatoprotective ...

Purification and kinetic characterization of polyphenol oxidase from Barbados cherry (Malpighia glabra L.)

Food Chemistry, 2008
Polyphenol oxidase (PPO) of Barbados cherry was extracted and purified through ammonium sulfate precipitation, gel filtration, and affinity chromatography. The purification factor for PPO was 60% with 8.3% yield. The enzyme was characterized for thermal stability, pH and kinetic parameters.

Partial Purification and Characterization of Pectin Methylesterase from Acerola (Malpighia glabra L.)

Journal of Agricultural and Food Chemistry, 2002
The enzyme pectin methylesterase (PME) is present in acerola fruit and was partially purified by gel filtration on Sephadex G-100. The results of gel filtration showed different PME isoforms. The total PME (precipitated by 70% salt saturation) and one of these isoforms (fraction from Sephadex G-100 elution) that showed a molecular mass of 15.5 +/- 1.0 ...

Antigenotoxicity and Antioxidant Activity of Acerola Fruit (Malpighia glabra L.) at Two Stages of Ripeness

Plant Foods for Human Nutrition, 2011
Genotoxic and antigenotoxic effects of acerola fruit at two stages of ripeness were investigated using mice blood cells. The results show that no ripeness stage of acerola extracts presented any genotoxic potential to damage DNA (Comet assay) or cytotoxicity (MTT assay).

OPTIMIZATION OF PROCESSING CONDITIONS FOR WINE PRODUCTION FROM ACEROLA (MALPIGHIA GLABRA L.)

Acta Horticulturae, 2010
In the present work, an attempt has been made to standardize the processing conditions for the manufacture of wine from acerola (Malpighia glabra L.) by RSM optimization. A central point design was used to evaluate the effect of soluble solids (°Brix) and the concentration of fruit pulp on sensorial quality attributes (color, flavor and aroma) of wine ...

Purification and characterization of pectin methylesterase from acerola (Malpighia glabra L.)

Journal of the Science of Food and Agriculture, 2007
AbstractThe enzyme pectinmethylesterase (PME) from acerola was extracted and purified by gel anion‐exchange chromatography (Q Sepharose) and filtration on Sephadex G‐100. The results showed two different PME isoforms (PME1 and PME2), with molecular masses of 25.10 and 5.20 kDa, respectively.

Genotoxic and Antigenotoxic Activity of Acerola (Malpighia glabra L.) Extract in Relation to the Geographic Origin

Phytotherapy Research, 2012
Malpighia glabra L, popularly known as acerola, is considered a functional fruit and therefore is taken to prevent disease or as adjuvant to treatment strategies, since the fruit is an undeniable source of vitamin C, carotenoids, and flavonoids. Acerola is a natural source of vitamin C, flavonoids, and carotenoids.

Screening of supports for the immobilization of pectinmethylesterase from acerola (Malpighia glabra L)

Journal of Chemical Technology & Biotechnology, 2004
AbstractA partially purified extract of pectinmethylesterase (PME) from acerola fruit was immobilized on various supports: glass, celite, chrysotile, agarose, concanavalin A Sepharose 4B, egg shell, polyacrylamide and gelatin. In addition, reticulation with glutaraldehyde was assessed, as well as the use of gelatin in the presence of celite, glass and ...
