Abstract

Annealing purple sweet potato flour is a type of purple sweet potato flour processed using the annealing starch modification technique. The production of purple sweet potato flour involves a drying process, where the drying method significantly influences the final quality of the annealing purple sweet potato flour. The objective of this study was to determine the optimal drying method for producing annealing purple sweet potato flour with an intense purple color and high anthocyanin content, there by enhancing its physical appearance. The research employed a descriptive method followed by a difference test (t-test). The results indicated that the best drying method was sun drying, which produced purple sweet potato flour with the following characteristics: moisture content of 8.65%, anthocyanin content of 10,899.2 ppm, color intensity values of L 42.42, a* 27.88, and b* -9.02, initial gelatinization temperature of 75.56°C, peak viscosity of 417.75 cP, breakdown viscosity of 20 cP, and setback viscosity of 150.25 cP. Sun drying effectively preserved the deep purple color of the flour, resulting in an attractive appearance.

Abstract

Abstrak: Informasi nilai gizi pada produk pangan merupakan elemen penting yang mendukung transparansi, keamanan pangan, dan peningkatan daya saing produk IKM di pasar modern. Namun, mayoritas pelaku Industri Kecil dan Menengah (IKM) di Jawa Barat belum memiliki pemahaman maupun keterampilan teknis dalam menyusun label informasi nilai gizi secara mandiri. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan pelaku IKM melalui sosialisasi, pelatihan, dan workshop penyusunan label informasi nilai gizi berbasis perhitungan komposisi bahan pangan. Metode pelaksanaan mencakup penyuluhan, simulasi, dan pendampingan langsung, yang dilakukan oleh tim Universitas Padjadjaran dan Dinas Perindustrian dan Perdagangan Jawa Barat (Indag Jabar) kepada mitra yaitu IKM Jawa Barat sebanyak 50 IKM. Hasil evaluasi observasi menunjukkan bahwa partisipasi dalam diskusi tergolong sangat tinggi (3,6/4), aspek simulasi penyusunan label gizi cukup tinggi (3,1/4), kemandirian teknis sedang (2,6/4), aspek respon terhadap umpan balik tinggi (3,4/4), dan kemampuan menggunakan alat bantu sederhana sedang (2,8/4). Kegiatan ini menunjukkan bahwa pendekatan edukatif dan aplikatif secara langsung mampu membekali pelaku IKM dengan keterampilan praktis yang relevan dan bermanfaat. Sebagai tindak lanjut, direkomendasikan adanya pendampingan berkelanjutan untuk memperluas dampak kegiatan ini.Abstract: Nutrition fact on food products is a crucial element that supports transparency, food safety, and enhances the competitiveness of small and medium enterprises (SMEs) in modern markets. However, the majority of SME actors in West Java still lack the understanding and technical skills to independently create nutrition fact labels. This community service activity aimed to improve the knowledge and skills of SME actors through socialization, training, and workshops on preparing nutrition fact labels based on the calculation of food composition. The implementation method included counselling, simulation, and direct mentoring conducted by the team from Universitas Padjadjaran in collaboration with the West Java Office of Industry and Trade to partners, namely 50 West Java IKM. The results of the observational evaluation showed that participation in discussions was categorized as very high (3.6/4), the aspect of nutrition fact simulation was quite high (3.1/4), technical independence was low (2.6/4), responsiveness to feedback was high (3.4/4), and the ability to use simple tools was moderate (2.8/4). This activity demonstrated that an educational and practical approach can effectively equip SME actors with relevant and applicable practical skills. As a follow-up continued mentoring is recommended to broaden the impact of this program.

Abstract

Lemon peel has various benefits and can be processed into higher-value products such as vinegar. Generally, vinegar is an acidic compound composed of acetic acid produced through a two-stage fermentation process. However, in this study, an innovation was introduced to convert acetic acid into lactic acid using Lactobacillus plantarum as the fermenting agent and sugar as the nutrient source. The aim of this study was to determine the effect of varying concentrations of L. plantarum and sugar on the chemical, physical, microbiological, and organoleptic characteristics of lemon peel vinegar. This study employed a Randomized Complete Block Design (RCBD) consisting of two factors: L. plantarum concentration (5%, 10%, 15%) and sugar concentration (15%, 10%, 5%). The results showed that the concentration ratio of L. plantarum and sugar significantly affected several characteristics of the lemon peel vinegar product. The best treatment was found in treatment A3, which used 15% L. plantarum and 5% sugar, with the following characteristics: moisture content of 93.43%, vitamin C content of 41.61 mg/100g, total titratable acidity (TTA) of 0.97%, pH of 2.76, viscosity of 3.72 cP, total plate count (TPC) of 13.75×10⁷ CFU/ml, and organoleptic test scores of 2.66 for color preference, 2.74 for aroma, 2.53 for taste, and 2.68 for texture.
