Abstract

Butterfly pea flowers have potential as an herbal plant with benefits for the body. Butterfly pea flower tea is purple in color due to anthocyanin pigments, which have high antioxidant activity. Butterfly pea flowers are perishable, so drying can be used to extend their shelf life. In this study, drying was carried out using two methods, namely a cabinet dryer and sunlight. The dried blue pea flowers were then brewed with water at various pH levels to determine panelist preferences and antioxidant properties, with the addition of lime juice at varying pH levels. In this study, butterfly pea flowers were dried in a cabinet dryer for 9 hours and in the sun for 8 hours. The dried butterfly pea flowers were then brewed with water at pH 3, pH 5, and pH 7. The results showed that the brew from sun-dried flowers was preferred by the panelists. The brew with water at pH 3 was preferred over the other treatments. The brew had the following criteria: L*, a*, and b* values of 31.99, 13.94, and -2.87, respectively; moisture content of 5.53%; antioxidant activity of 33.12% (RSA); and total phenol content of 182.65 mg EAG/g.

Abstract

Cookies umumnya terbuat dari tepung terigu, namun juga dapat dibuat menggunakan bahan alternatif seperti tepung umbi-umbian, kacang-kacangan, atau buah-buahan. Salah satu alternatif tepung terigu yang menjanjikan adalah mocaf. Bubuk teh hitam kaya akan antioksidan sehingga berpotensi sebagai bahan pembuatan cookies bernutrisi. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan bubuk teh hitam dengan kualitas berbeda—Broken Orange Pekoe (BOP), Broken Orange Pekoe Fanning (BOPF), dan Pekoe Fanning (PF)—pada konsentrasi 2%, 4%, dan 6% terhadap sifat fisik, kimia, aktivitas antioksidan, serta mikrostruktur cookies terigu–mocaf. Rancangan percobaan dalam penelitian ini menggunakan Rancangan Acak Lengkap. Cookies diuji kekerasan, tingkat pengembangan, warna (nilai L*, a*, b*), aktivitas antioksidan, serta mikrostrukturnya. Hasil penelitian menunjukkan bahwa kekerasan meningkat seiring dengan penambahan konsentrasi bubuk teh hitam semua kualitas, dengan nilai tertinggi dicapai oleh BOP 6% sebesar 3.871,83 g. Peningkatan konsentrasi teh menurunkan daya kembang cookies pada semua kualitas teh. Penambahan bubuk teh hitam menurunkan nilai L*, a*, b*, sehingga produk menjadi lebih gelap, kurang merah, dan kurang kuning. Cookies terigu-mocaf dengan penambahan 4% PF menghasilkan cookies dengan mikrostruktur kompak dan aktivitas antioksidan tinggi sebesar 28,45% RSA. Dengan demikian, cookies terigu-mocaf dengan penambahan bubuk teh hitam memengaruhi karakteristik fisik dan kimianya serta meningkatkan nilai gizi, sehingga menjadikannya cookies fungsional.

Abstract

One of the plants that is quite famous is katuk leaves. Katuk leaf plants by the community are only used as vegetable food and food coloring. Therefore, the effort that can be done is through a processing process, namely making katuk leaves into flour and katuk leaf pulp so that they are easily mixed in other ingredients and then processed into products in the form of chips. The purpose of this study was to determine and determine the effect of adding katuk leaf flour and katuk leaf pulp on physical and chemical properties and the level of preference for katuk leaf chips. This research was conducted by making chips made from wheat flour substituted with flour and katuk leaf pulp using a Completely Randomized Design (CRD) with research factors substitution of 20%, 25% and 30% of katuk leaf flour and pulp with physical analysis of color and texture, Chemical analysis of selected treatment included total phenolic content, water, ash, fat, protein, and carbohydrate as well as preference test. The data were tested using SPSS and if they were significantly different, the Duncan's Multiple Range Test continued with a significant level of 0.05. The results showed that 20% katuk leaf flour substitution chips and 25% katuk leaf pulp were the treatments chosen by the panelists. The physical characteristics tested include L, a*, b* and texture. Chemical characteristics include analysis of total phenolic content, which is 242.6 mg GAE/g and 66.3 mg GAE/g, water content is 5.25 %w/w and 5.85 %w/w, ash content is 1.47 %w/w. and 1.30 %w/w, fat content of 2.46 %w/w and 8.08%w/w, protein content of 8.77 %w/w and 8.10%w/w, carbohydrate content of 80.24 %w/w and 76.62 %w/w and favored by the panelists.
