Abstract

Turmeric is a tropical plant from Asia and has now spread to subtropical regions around the world. Instant turmeric is generally in the form of a small powder and is easily dissolved in water. The manufacture of instant turmeric using turmeric and sugar raw materials and lemongrass is an effort to utilize local foodstuffs. The use of lemongrass as an additional ingredient is expected to increase the preference for instant powder. Purpose To determine the effect of variations in the addition of tablegrasshopper extract and sugar on the physical, chemical, and preference levels of instant turmeric. completely randomized design 2 factors, namely the addition of the amount of sugar (500; 1000; and 1500 g) and the variation of adding lemongrass extract (0; 20; and 40 ml). The instant turmeric products produced were then physically tested and the level of preference, and the selected instant turmeric was chemically analyzed (moisture content, antioxidant activity of DPPH (2,2-diphenyl-1-pycrylhydryl) and total phenol). The data obtained was statistically calculated with ANOVA and a 95% confidence level. The results showed that the addition of the amount of sugar (500; 1000; and 1500 g) and the variation of the addition of lemongrass extract had an effect on the resulting turmeric. The selected instant turmeric product is the addition of 20 g of lemongrass extract and the addition of 1000 g of sugar which has a moisture content of 0.94%, DPPH antioxidant activity of 54.63% RSA, and a total phenol of 4.41 mg EAG/g bk.)

Abstract

Jelly candy is a soft, elastic confection widely consumed by people of all ages. The innovation of functional jelly candy in this study involved the incorporation of bidara leaf extract and mango pulp to enrich bioactive compounds with antioxidant potential. A factorial randomized block design was used with two factors: the ratio of bidara leaf extract to mango pulp (60:40, 50:50, and 40:60 v/v) and the addition of gelatin (15, 20, and 25 g). The study aimed to obtain a jelly candy formulation with desirable physical, chemical, and sensory qualities and antioxidant activity. The research stages included preparing bidara leaf extract, mango pulp, and jelly candy, followed by analysis of their physical, chemical, and sensory characteristics. Data were statistically analyzed using SPSS Version 25.0 with Univariate Analysis of Variance, followed by One-Way ANOVA and Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that increasing the ratio of bidara leaf extract to mango pulp and adding gelatin increased hardness, elasticity, color intensity, total phenolics and flavonoids, and decreased moisture content. Total phenolic and flavonoid contents increased with treatment. The best formulation was obtained at a 40:60 ratio and 20 g gelatin, producing 25.13% RSA antioxidant activity, 0.98% ash, and 0.20% reducing sugar, indicating potential as a functional food.

Abstract

Kunyit memiliki potensi dalam pangan fungsional karena mengandung sifat antioksidatif yang berasal dari senyawa kurkuminoid. Oleh karena itu, kunyit ditambahkan pada stick ditambahkan yang merupakan camilan digemari oleh masyarakat. Stick dibuat dari campuran tepung terigu dan tepung garut, maka dari itu perlu ditambahkan baking powder untuk membentuk tekstur stick agar lebih renyah. Metode penelitian ini dilakukan menggunakan rancangan acak lengkap faktorial dengan 2 faktor dengan penambahan bubuk kunyit dengan variasi 5, 10 dan 15 g dan baking powder dengan variasi 0,15 g, 0,30 g, dan 0,45 g. Penambahan bubuk kunyit dan baking powder berpengaruh terhadap tingkat kesukaan, warna (lightness, redness dan yellowness), tekstur dan kadar air. Berdasarkan tingkat kesukaan stick terigu-garut terbaik dihasilkan dengan penambahan bubuk kunyit 5 g dan baking powder 0,30 g yang berturut memiliki sifat kimia kadar protein sebesar 8,48% (b/b), aktivitas antioksidan 53,82% RSA (DPPH) dan 5,64 mg E Fero/g (FRAP) serta kadar fenol total 20,88 mg EAG/g.
