Abstract   Celery plants (Apium graveolens L.) have long been used as ingredients of traditional medicine as antihypertensive by the people of Indonesia. This study aims to determine the effect of variations in the addition of celery leaf extract on the manufacture of functional food in the form of syrup from celery leaf extract (Apium graveolens L.) on organoleptic assessment and the quality of syrup preparations. This study used a Completely Randomized Design (CRD) consisting of 5 types of treatment and each treatment was repeated 3 times. Variation of addition of celery leaf extract as follows: (M0) = 0% (control), (M1) = 0.33% (0.55 g), (M2) = 0.39% (0.65 g), (M3 ) = 0.51% (0.85 g) and (M4) = 0.6% (1 g). The results showed that celery leaf extract had antioxidant activity with IC50 values ​​of 98.24 µg / mL and positive (+) containing flavonoids. The addition of celery leaf extract to syrup has a very significant effect on organoleptics (aroma and taste), 7th day pH and viscosity, and all homogeneous syrups. The most preferred treatment panelist was treatment M1 (0.33%) with a scoring score of 4.03 (likes) and a taste of 3.93 (likes) and according to SNI. While the panelists preferred the treatment of M4 (0.6%) with a scoring score of 3.24 (rather like) and flavor of 2.87 (rather like) but according to SNI. The fewer additions of celery leaf extract, the syrup is increasingly preferred by panelists.   Keywords: celery, formulation, syrup

This study aims to determine the effect of adding soursop leaf extract (SLE) at level 0 (control), 2, 4, and 6% (the weight of SLE /the weight of the dough) on the physical, organoleptic and antioxidant qualities of chicken sausages. A Completely Randomized Design (CRD) was used in this study. Data analysis was performed using analysis of variance (ANOVA) and further tested using the Least Significant Difference Test (LSD). The results showed that differences in SLE levels did not significantly affect the physical quality of chicken sausages, but did change the color, aroma, texture, and taste. The color, smell, texture, and taste of chicken sausage with the addition of 6% SLE showed results that appeared to be greener, had a stronger soursop aroma, more elastic, and tasted more bitter than the other treatments (P <0.05). The lowest antioxidant activity was shown by SLE 0% in both the dough (39.78%) and cooked sausage (17.10%). The highest antioxidant activity was SLE 6%, with antioxidant activity of 57.63% in the dough and 37.43% in cooked sausages. The addition of chicken sausage does not affect physical quality but has a significant impact on the soursop leaf extract test on organoleptic color, aroma, texture, and taste. The best organoleptic quality is demonstrated at 4% SLE. The addition of soursop leaf extract level is accompanied by increased levels of antioxidants both in the dough and in cooked sausage.

ABSTRACT Salinity influences all germination stages and may adversely affect seedling establishment in the field. The objective of this research was to determine the relationship between the antioxidant activity and the physiological performance of seeds and to verify the efficacy of the imaging analysis of popcorn seedlings after seed exposure to saline stress. A completely randomized design was used that consisted of four replicates in a factorial scheme. This scheme comprised three popcorn hybrids (P618, AP6002, and AP8203) and five saline potential levels (0.0; -0.1; -0.3; -0.6, and -0.9 MPa) that were obtained from KCl solutions of different concentrations. First count germination, germination and seedling vigor classification (strong normal seedlings), and dry mass of seedlings were evaluated to determine the physiological quality of the seed. The images of seedlings were used to evaluate the coleoptile and root lengths, indices of vigor, uniformity, and growth using the Groundeye® software. The activities of the antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), and catalase (CAT) were also determined. Saline stress compromises the physiological quality and antioxidant activity of seeds and the performance of popcorn seedlings. Computerized image analysis using Groundeye® was efficient in evaluating the popcorn seedlings after being subjected to salt stress. Hybrids AP6002 and AP8203 were more tolerant to salt stress than hybrid P618.
