description: Im Datensatz "COVID-19-Hospitalisierungen in Deutschland" des Robert Koch-Institutswerden täglich aktualisierte Informationen zu Hospitalisierungen im Zusammenhang mit COVID-19 basierend auf den Meldungen nach dem Infektionsschutzgesetz (IfSG) bereitgestellt. Neben tagesaktuellen Fallzahlen und Inzidenzen auf Bundes- und Länderebene enthält der Datensatz auch modellgestützte Schätzungen verzögert gemeldeter Hospitalisierungen mittels Nowcasting. Ziel ist es, die tatsächliche Belastung des Gesundheitssystems durch COVID-19 besser abzubilden, insbesondere durch die Berechnung adjustierter 7-Tage-Hospitalisierungsinzidenzen.

title: การผลิตผงสีจากวัสดุธรรมชาติ เพื่อผลิตภัณฑ์อาหาร

description: งานวิจัยนี้มีวัตถุประสงค์ เพื่อศึกษาการสกัดสารสีที่ได้จากวัสดุธรรมชาติและนำไปผลิตผงสีที่เหมาะสำหรับใช้ในผลิตภัณฑ์อาหาร โดยมุ่งศึกษาเฉพาะการสกัดสีจากวัสดุธรรมชาติหรือผลิตผลทางการเกษตรที่มีสีเหมือนหรือใกล้เคียงกับแม่สีหลักที่ใช้ในระบบการพิมพ์ ได้แก่ สีม่วงแดง สีเหลือง สีน้ำเงินเขียว และสีดำ ที่เหมาะสำหรับใช้ในผลิตภัณฑ์อาหาร และหาอัตราส่วนที่เหมาะสมในการนำไปใช้ของสารละลายสี โดยสังเกตจากค่าความแตกต่างสี (∆E) ของสารละลายสีที่มีความใกล้เคียงกับค่าสีตามมาตรฐาน ISO 12647-6 และนำมาตรวจสอบสารตกค้างในผงสี ผลการวิจัยพบว่า การสกัดสารสีด้วยวิธีการต้มวัสดุธรรมชาติในตัวทำละลายน้ำเป็นวิธีการสกัดสารสีที่เหมาะสมที่สุดในงานวิจัยนี้ และวัสดุธรรมชาติที่ให้สารสีม่วงแดง สีเหลือง สีน้ำเงินเขียว และสีดำ ที่มีค่าสีใกล้เคียงกับค่าสีมาตรฐานมากที่สุด ได้แก่ ดอกกระเจี๊ยบแดง ดอกคำฝอย ดอกอัญชันแห้ง และกาแฟผสมกับดอกอัญชันแห้ง ตามลำดับ และเมื่อนำสารสีที่ได้จากวัสดุธรรมชาติไปทำการผลิตเป็นผงสี พบว่า เมื่อเติมสารตัวพาจำพวกมอลโตเด็กซ์ตรินลงในสารสกัดสีก่อนการทำแห้งพ่นฝอยจะทำให้ได้ปริมาณผงสีสีม่วงแดง สีเหลือง สีน้ำเงินเขียว และสีดำ เพิ่มขึ้นร้อยละ 71, 49, 15 และ 8 ตามลำดับ แต่ส่งผลให้มีค่าความแตกต่างสีเพิ่มขึ้น ยกเว้นสีน้ำเงินเขียวที่มีค่าความแตกต่างสีลดลง และจากการตรวจสอบปริมาณสารพิษตกค้างในผงสี พบว่า มีเฉพาะผงสีสีม่วงแดงและสีเหลือง ตรวจพบแคดเมียมตกค้างแต่อยู่ในเกณฑ์มาตรฐานการผลิตผงสีเพื่ออุตสาหกรรมอาหาร ดังนั้น ผงสีที่ผลิตได้จึงสามารถนำไปใช้เพื่อผลิตภัณฑ์อาหารได้
