Abstract

Tomatoes represent a promising raw material for conversion into candied fruit due to their texture and flesh, which possess a distinctive sour taste well-suited for this application. This study seeks to evaluate the impact of varying sugar concentrations during the cooking process on the physical and chemical properties of candied tomatoes. Variations in sugar concentration influence the water content, texture, and color of the resultant candied tomatoes. The lowest water content, 4.6%, was achieved with a 60% sugar concentration. Texture analysis revealed that the highest hardness value was also obtained with a 60% sugar concentration. Additionally, the candied tomato samples exhibited the highest level of redness in the final product when a 60% sugar concentration was employed. These findings suggest that sugar concentration differentially affects the tested attributes, with a 60% concentration yielding the highest values in texture and color analysis, while resulting in the lowest water content compared to the 50% and 40% sugar concentrations.

Abstract

The use of non-food dyes is a problem in food safety. One of the efforts to solve this problem is the making of natural coloring products from purple sweet potato anthocyanin pigments. Anthocyanins are sensitive to oxidative damage, so encapsulation techniques need to be used to preserve bioactive compounds. Encapsulation with the coacervation method involves coating anthocyanins as the active ingredient with pectin and alginate as gel matrices, based on the principle of ionic gel formation. This study aimed to determine the optimal alginate concentration for the formation of anthocyanin encapsulates and to identify the color characteristics and interactions of the encapsulated anthocyanins from purple sweet potato. This study used various concentrations of alginate (0%, 0.5%, 1%, and 1.5%). The research parameters used were total anthocyanin and antioxidant activity (IC50). The findings indicated that the optimal concentration of alginate for preserving the solubility and stability of anthocyanin, derived from the bioactive compounds in purple sweet potatoes, was 1% alginate. This concentration resulted in a total anthocyanin content of 20.77 mg/L and an antioxidant activity (IC50) of 4049.73 ppm. A higher alginate concentration results in stronger gel formation; however, it simultaneously weakens the ability of alginate to bind anthocyanin as an active ingredient. This is attributed to the increase in viscosity, making the incorporation of the anthocyanin matrix into the encapsulates more difficult. Despite the very weak antioxidant activity, these anthocyanin encapsulates hold potential as natural food colorants for safe applications in acidic food products like beverages.

Abstract

Buah naga merah (Hylocereus polyrhizus) berpotensi sebagai bahan baku minuman fermentasi fungsional karena mengandung gula alami, pigmen betalain, dan senyawa bioaktif. Namun, pemanfaatannya masih terbatas pada daging buah, sedangkan kulit buah sering dibuang meskipun memiliki kandungan gizi dan komponen fungsional bernilai. Penelitian ini bertujuan mengevaluasi pengaruh bagian buah serta fermentasi menggunakan Lactobacillus plantarum terhadap karakteristik sensori dan fisikokimia minuman berbasis buah naga merah. Penelitian menggunakan rancangan acak lengkap faktorial dengan dua faktor, yaitu bagian buah (daging dan kulit) dan kondisi fermentasi (tanpa fermentasi dan fermentasi). Hasil penelitian menunjukkan bahwa fermentasi menghasilkan aroma asam khas, warna lebih pucat, dan tekstur lebih encer, terutama pada minuman berbasis kulit buah naga. Fermentasi menurunkan pH dari 5,74 menjadi 3,08 serta menurunkan total padatan terlarut dari 5,50 menjadi 3,73 °Brix. Minuman berbasis daging buah memiliki total padatan terlarut lebih tinggi, sedangkan minuman berbasis kulit buah menghasilkan pH lebih rendah. Daging dan kulit buah naga berpotensi dikembangkan sebagai bahan baku minuman fungsional yang bernilai tambah.
