KIRMIZI BİBER PÜRESİNİN VERİM VE KALİTESİNE MİKRODALGA ISITMANIN ETKİSİ

Hamza Bozkir; Ahsen Rayman Ergün; Özge Taştan; Taner Baysal

Bu calismada kirmizi biber puresinin verim ve kalitesi uzerine konvansiyonel isitma teknigine alternatif olarak mikrodalga isitma teknigi uygulanmistir. Mikrodalga isitma uygulamasi verim ve cikis sicakligi cevap olacak sekilde yanit yuzey metodu ile optimize edilmistir. Mikrodalga isitma uygulamasinin yanit yuzey metodu ile optimum kosullari 900 W guc ve 6.52 rpm akis hizi olarak saptanmistir. Bu optimum calisma kosullarinda verim ve cikis sicakligi %76.76 ve 95 °C olarak bulunmustur. Konvansiyonel isitma uygulamasi da mikrodalga isitmada ulasilan ayni sicaklik derecesinde 95°C ve 9 dk olarak yurutulmustur. Sonuc olarak mikrodalga isitma uygulamasi ile verimde %8.07, pektin iceriginde %17.75, C vitamin iceriginde %20.6 artis saptanmistir.Bu calismada kirmizi biber puresinin verim ve kalitesi uzerine konvansiyonel isitma teknigine alternatif olarak mikrodalga isitma teknigi uygulanmistir.

Investigating the Effects of Current and Wave Form of Electrical Pre-treatments on the Yield and Quality of Tomato Juice

Abstract In this study, the effects of different current and wave forms of electrical application by electroplasmolyzator on the production of tomato juice were investigated. The whole electrical design can be divided into three subtitles. The three subtitles are used for only auto-transformer outputs for “AC (alternative current) voltage”, and the AC rectification for “DC” (direct current) voltage and the gate drive of the switching devices for “square waves”. Yield, lycopene content and color values were compared for these different current and wave forms. As a result the yield increase was found mostly in the AC-treated group which has square wave form and bipolar single phase (100 V–90 s). Lycopene was also found mostly in the same group. Significant differences were found between the groups that are treated with different current and wave forms.
