Abstract

<p><strong><em>Abstract:</em></strong><em> Pandanus leaf and </em><em>B</em><em>ixa orellana linn seed can be used as natural colourant. This colourant has a beautiful colour effect and hardly to be imitated by synthetic colourant.</em><em> Based on other study, n</em><em>atural colourant concentrate from </em><em>these</em><em> seed </em><em>was</em><em> tested into soaked food and dried foodl in order </em><em>to </em><em>increase food quality. </em><em>In this study, we used</em><em> </em><em>P</em><em>andanus leaf and </em><em>B</em><em>ixa orellana linn seed with water as solvent</em><em> in extraction process. Colourant and solvent was then separated by distillation. </em><em> </em><em>A</em><em>bsorb</em><em>a</em><em>ncy and pH</em><em> of product were then analysized.</em><em> Absorbency </em><em>analysis was conducted</em><em> </em><em>using</em><em> pectrophotometer.</em><em> E</em><em>xtraction</em><em> of 1</em><em> kg of raw material and 5 </em><em>L</em><em> of </em><em>water at </em><em>100<sup>o</sup>C </em><em>in stirred tank for </em><em>30 minutes </em><em>operation </em><em>produce</em><em>d</em><em> a thin colourant substance. Distillation</em><em> of this substance </em><em>at 100<sup>o</sup>C </em><em>produced 300 mL of concentrated substance. We found that 1 kg</em><em> of </em><em>P</em><em>andanus le</em><em>af</em><em> </em><em>generate</em><em> 60</em><em>.</em><em>66 grams of colourant substance and </em><em>1 kg</em><em> of </em><em>B</em><em>ixa orellana linn seed </em><em>generate</em><em> 119</em><em>.</em><em>14 grams. </em><em>Absorbancy </em><em>analysis</em><em> of product</em><em> at 520 nm length of wave and pH 5-6 </em><em>showed that</em><em> concentration of </em><em>product from B</em><em>ixa orellana linn  seed </em><em>is</em><em> higher than </em><em>product from P</em><em>andanus </em><em>leaf</em><em>. </em><em>Products of liquid</em><em> colourant substance </em><em>were</em><em> </em><em>then </em><em>tested into soaked and dried food</em><em> such as </em><em>Bolu Kukus cake</em><em>, </em><em>Klepon</em><em> and</em><em> Rengginang. Liquid colourant substance </em><em>from P</em><em>andanus leaf give</em><em>s</em><em> brown and dark green </em><em>colour </em><em>with fragrance</em><em>,</em><em> whereas </em><em>B</em><em>ixa orellana linn seed gives dark yellow and dark red colour with distinctive smell.</em><em></em></p><p><strong><em> </em></strong><strong><em>Keyword</em></strong><strong><em>s</em></strong><strong><em>: </em></strong><em>natural colour, pandanus and bixa orellana linn, consentrate.</em></p>
