Antioxidant capacity of the striped sunflower seed (Helianthus annuus L.) aqueous extract

KUALITAS MINYAK BUNGA MATAHARI KOMERSIAL DAN MINYAK HASIL EKSTRAKSI BIJI BUNGA MATAHARI (Helianthus annuus L.) ABSTRAK Minyak komersial dan minyak hasil ekstrasi dari biji bunga matahari melalui uji kadar air, kadar asam lemak bebas, bilangan peroksida. Analisis hasil ekstrak biji bunga matahari diperoleh kadar air 0,43%, kadar asam lemak bebas 0,47% dan bilangan persoksida 5,22 mek/kg. analisis minyak komersial diperoleh kadar air 0,21%, kadar asam lemak bebas 0,28% dan bilangan peroksida 4,18 mek/kg. Hasil analisis dengan kromatografi gas kedua sampel menunjukkan kadar asam lemak bebas berbeda. Berdasarkan uji kualitas yang dilakukan terhadap kedua sampel yang dianalisis terdapat hasil yang diperoleh tidak memenuhi syarat yang ditentukan yakni kadar asam lemak bebas 0,08% dan bilangan peroksida 2 mek/kg. Kata kunci: Asam lemak bebas, bilangan proksida, minyak biji bunga matahari QUALITY OF COMMERCIAL SUNFLOWER OIL AND OIL EXTRACTION SEEDS SUNFLOWER (Helianthus annuus L.) ABSTRACT Experimental study of analyzing the extract oil from sunflower seed compare with the commercial sunflower seed oil according to the company standard which includes determining of moisture content, free fatty acid content, peroxide value and the fatty acids compositions is reported in this paper. The result show that the moisture content of the extract oil is 0,43%, free fatly acid content is 0,47%, and the peroxide value is 5,22% mek/Kg. For the commercial sunflower seed oil company product that is 0,21% for the moisture, free fatty acid is 0,28% and the peroxide value is 4,89 mek/Kg. The gas chromatography analysis indicated that the most fatty acid from both samples is linoleic acid. The quality of the extract sunflower seed oil has not been improved to conform with the commercial quality according to the company standard, that is 0,08% for the free fatty acid and 2 mek/Kg for the peroxide value. Keywords: Free fatty acid, peroxide value, sunflower seeds oil

Rhizopus Rot

Larvae of the moth Homoeosoma electellum (Hulst.) were found consistently in sunflower (Helianthus annuus L.) seed heads affected with Rhizopus rot in California. Both Rhizopus rot and larvae were found in 88% of the rotted heads examined and only Rhizopus rot was evident in 12% of the heads. Head rot developed in 55–100% of the sunflower heads artificially inoculated in the field with both Rhizopus oryzae Went & Brinsen-Geerlings and H. ellectellum larvae and in 5–20% of the heads inoculated only with Rhizopus. Rot did not occur in heads in which only larvae were present. Larvae enhanced infection of the receptacle by Rhizopus through feeding injury. Ingested spores that are viable after passage through the gut of a larva can be spread by larvae into the inner tissues of the sunflower receptacle.
