| Summary: | Melinjo (Gnetum gnemon L.) is a plant native to southeast Asia and the western Pasific Ocean Islands. <br />
<br />
<br />
<br />
In Indonesia, melinjo is used widely as a daily cuisine for example “emping”and is one of the <br />
<br />
<br />
<br />
ingredients used in “acid soup”. Melinjo hard shell extract has proven to have various <br />
<br />
<br />
<br />
pharmacological activities, one of them is as antihyperuricemia through inhibiting xanthin oxidase <br />
<br />
<br />
<br />
which has role in forming uric acid. Melinjo hard shell extract has a sticky characteristic due to high <br />
<br />
<br />
<br />
polysaccharide content. For that reason, neusilin (Magnesium Aluminum Silicate) is used as an <br />
<br />
<br />
<br />
absorbent combined with maltodextrin during extract powderization using spray drying process. The <br />
<br />
<br />
<br />
aim of this study is to determine the effect of maltodextrin and neusilin concentration on physical <br />
<br />
<br />
<br />
properties of the extract like the flow characteristic. In addition but more importantly, the inhibotry <br />
<br />
<br />
<br />
activity on xanthin oxidase in vitro after drying process. Different concentrations of maltodextrin did <br />
<br />
<br />
<br />
not influence melinjo hard shell extract flow characteristic (0,722; p<0,05). On the other hand, <br />
<br />
<br />
<br />
different concentration of neusilin showed significant difference on the flow characteristic (0,000; <br />
<br />
<br />
<br />
p<0,05). There is a relationship between maltodextrin and neusilin concentration on melinjo hard <br />
<br />
<br />
<br />
shell extract flow characteristic (0,000; p<0,05). The more amount of neusilin added on the extract, <br />
<br />
<br />
<br />
the better of the extract flowability. The spray drying process supported with the use of neusilin and <br />
<br />
<br />
<br />
maltodextrin combination maintained the inhibitory effect of the extract on xanthin oxidase. <br />
