Abstract

Damage to fresh food such as fruits and vegetables due to exposure to air and humidity has become a common problem in the community. One innovative solution to maintain food quality is the use of starch-based edible films. This study aims to determine the effect of glycerol concentration on the physical and chemical characteristics of a starch-based edible film of purple sweet potato (Ipomoea batatas L.). The study was conducted using a Complete Random Design (RAL) with five treatments of glycerol concentrations of 6%, 8%, 10%, 12%, and 13% (v/b starch). The parameters tested include tensile strength, elongation, thickness, folding, moisture transmission rate (WVTR), and moisture content. The results showed that the increase in glycerol concentration had an effect on all the physical characteristics of edible films, except WVTR. Edible films with a glycerol concentration of 13% show the best characteristics with the highest elongation values (4.39%), highest folding (28 folds), thickness (0.07 mm), tensile strength (12.60 MPa), WVTR (0.02g/cm2.h) and moisture content (17.68%). Meanwhile, the best edible film chemical characteristics according to the 1995 SNI standard are at a glycerol concentration of 8% (15.77). Overall, all concentrations of purple sweet potato starch have met some of the standard parameters of commercial edible films. However, it still lags behind in terms of elongation, moisture content and tensile strength. However, this edible film has enough potential for use in small-scale or household packaging applications.

Abstract

Edible film is a thin layer used to coat food or placed between food components, and it is consumable. This research aimed to assess the effect of adding teak leaf powder on the physical, chemical, and antibacterial properties of the edible film. The experiment was designed using a Completely Randomized Design (CRD), with teak leaf powder (J) as the independent variable. Four treatments were applied: J0 (0 g), J1 (0.25 g), J2 (0.50 g), and J3 (0.75 g) of teak leaf powder. Each formulation was tested for moisture content, thickness, tensile strength, elongation, water vapor transmission rate (WVTR), and antibacterial activity against environmental bacteria and Escherichia coli. The data obtained were analyzed using ANOVA followed by Tukey’s post hoc test at a significance level of α = 0.05. Physically, the addition of teak leaf powder increased the thickness of the edible film but decreased its tensile strength, elongation, and WVTR. The chemical parameter, moisture content, remained relatively stable across all treatments. In terms of antibacterial properties, the inhibition zone against environmental bacteria increased significantly. For Escherichia coli, no inhibition zone was observed in treatment J0, while treatments J1 to J3 demonstrated comparable antibacterial effectiveness.

Abstract

Corn noodles are a gluten-free and high-fiber food product, but contain relatively low levels of β-carotene. To enhance their nutritional value and visual appeal, pumpkin puree (Cucurbita moschata Duchesne), known for its high β-carotene content and natural coloring properties, was added to the formulation. This study aimed to evaluate the effects of pumpkin puree addition on the physical, chemical, and organoleptic characteristics of wet corn noodles. A completely randomized design with one factor was used, comprising four treatment levels: 10%, 20%, 30%, and 40% pumpkin puree based on the total flour weight. The results showed that pumpkin puree significantly increased moisture contents and β-carotene levels (p<0.05), with the highest values found in formulation F4 (40%)—moisture contents of 65.40% and β-carotene of 287.07 µg/100 g (db). However, formulation F3 (30%) demonstrated the most balanced attributes, including bright colour (a = 4.41and b 22.77), optimal texture (cohesiveness 0.21 and adhesiveness 1.89), and the highest overall anelist preference score (overall score 3.0). Therefore, adding 30% pumpkin puree is the optimal formulation for producing wet corn noodles that are nutritious, visually appealing, and well accepted by consumers.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan masyarakat mengenai diversifikasi olahan buah pepaya menjadi berbagai produk pangan bernilai tambah. Program dilaksanakan bersama Kelompok Wanita Tani (KWT) Rukun Kunden, Sidoluhur, Godean, Sleman. Tidak hanya berfokus pada produksi keripik pepaya yang sebelumnya telah dihasilkan mitra, tetapi juga mengembangkan produk lain seperti manisan basah, manisan kering, dan selai. Metode kegiatan meliputi pemaparan teori mengenai Cara Produksi Pangan Olahan yang Baik (CPPOB), teknik pengemasan, serta manajemen usaha, yang kemudian dilanjutkan dengan praktik langsung pembuatan manisan basah berupa cocktail pepaya. Melalui kegiatan ini, peserta memperoleh pengalaman dalam praktik pengolahan, pengemasan, serta penyimpanan produk agar siap dipasarkan. Peserta juga diharapkan mampu menyebarkan pengetahuan tersebut kepada masyarakat sekitar. Evaluasi menunjukkan adanya peningkatan rata-rata pengetahuan peserta sebesar 89,5%. Hal ini membuktikan bahwa kegiatan pengabdian telah memberikan nilai tambah sesuai dengan harapan anggota KWT. Kata Kunci: Pepaya, Proses Pengolahan, Manisan Basah, KWT.
