Abstract

Nasi merupakan makanan pokok kaya karbohidrat, sering dikonsumsi di Indonesia, namun kadar glukosanya yang tinggi dapat mempengaruhi kesehatan. Kebiasaan masyarakat menyimpan dan memanaskan kembali nasi memunculkan pertanyaan tentang dampaknya terhadap kadar glukosa. Penelitian ini bertujuan menganalisis perubahan kadar glukosa pada nasi putih, merah, dan hitam pada penyimpanan di kulkas (1-4℃) dan suhu ruang (20-25℃) selama 1, 3, dan 6 jam, serta setelah pemanasan kembali (65℃ selama 15 menit). Penelitian ini menggunakan metode quasi eksperimen dengan desain pretest-posttest only control. Sampel yang digunakan adalah nasi putih, nasi merah, dan nasi hitam. Nasi disimpan dalam dua kondisi suhu kulkas (1-4°C) dan suhu ruang (20-25°C), dengan variasi waktu penyimpanan 1 jam, 3 jam, dan 6 jam. Setelah penyimpanan, nasi dipanaskan kembali pada suhu 65°C selama 15 menit. Pengukuran kadar glukosa dilakukan menggunakan metode Luff-Schoorl. Data dianalisis menggunakan uji t berpasangan. Hasil penelitian menunjukkan bahwa nasi putih dengan penyimpanan pada suhu ruang selama 1 jam mempunyai kadar glukosa tertinggi, yaitu 8,0956%, dan terendah adalah nasi hitam dengan penyimpanan dalam kulkas selama 6 jam (3,8958%). Pada perlakuan pemanasan kembali, kadar glukosa tertinggi diperoleh dari nasi putih dengan penyimpanan pada suhu ruang selama 1 jam (8,2098%) dan terendah adalah nasi hitam dengan penyimpanan dalam kulkas selama 6 jam (4,0303%). Penyimpanan, waktu penyimpanan dan pemanasan memberikan pengaruh nyata terhadap perbedaan kadar glukosa dari nasi yang dicobakan. Hasil yang paling aman untuk penderita diabetes melitus adalah nasi hitam yang disimpan di kulkas selama 6 jam lalu dipanaskan kembali.

Abstract

Red cayenne pepper (Capsicum frutescens L.) is an important horticultural commodity in Indonesia with high demand; however, its high moisture content makes it highly perishable. One way to extend its shelf life is to process it into powder through drying. Drying using a food dehydrator is considered more effective because it allows precise control of temperature and time, which affects the final product quality, including moisture content, color, and vitamin C, β-carotene, and capsaicin levels. This study aimed to determine the effects of different drying temperatures and durations using a food dehydrator on the physicochemical characteristics of red cayenne pepper powder. A Completely Randomized Factorial Design was used with two factors: drying temperature (50, 60, and 70°C) and drying time (16, 20, and 24 h), resulting in nine treatment combinations with three replicates. The parameters observed included moisture content, yield, color (L*, a*, and b*), vitamin C, β-carotene, and capsaicin content. The results showed that increasing temperature and drying time significantly decreased the moisture content, yield, and vitamin C content, while increasing the brightness and redness of the pepper powder. β-carotene content increased at moderate temperatures and decreased at higher temperatures, while the highest capsaicin content was found at 60 °C for 20 h (998.96 ppm or 16,083.33 SHU) and decreased at 70 °C. Overall, drying at 60 °C for 20 h produced red cayenne pepper powder with optimal physicochemical quality.

Abstract

Strawberry is a very popular fruit due to their bright red color and aroma. sweet and slightly sour taste and nutritional value, especially vitamin C. Strawberries also contain anthocyanins, a reddish-purple pigment with high antioxidant activity. Nevertheless, they have a relatively short shelf life and are easily damaged because of their soft texture. They are usually processed into jam and other products that use high temperatures, which can damage nutritional compounds, including anthocyanins. Restructuring is an alternative method that can be used to extend the shelf life of strawberries without heat, thereby avoiding damage to the nutritional value and antioxidant activity. This study aimed to determine the effect of various Alginate and CaCl₂ concentrations (0, 0.1, 0.2, 0.3, 0.4, and 0.5%) on the quality of restructurized strawberries. The anthocyanin content was determined using the pH differential method; the texture was determined using a simple test to distinguish differences between treatments; the organoleptic test used hedonic methods with 30 panelists; and the shelf life tests were used to keep the real product until the quality decreased. Preliminary experiments showed that 2% alginate was optimal. The second step showed that 0.4% CaCl₂ was optimal.

Abstract

Vegetable consumption in Indonesia is low, particularly among preschool-aged children, who often do not meet daily intake recommendations. Sensory factors, such as taste, texture, and appearance, strongly influence children’s acceptance of vegetables. Previous studies have shown that modifying vegetables and using play-based learning can improve children’s interest. This study aimed to develop an edible folding paper made from vegetables, serving as both a nutritious food product and an interactive learning tool. Spinach, purple cabbage, and pumpkin were chosen for their good acceptance, nutrient content, and color appeal. The product was analyzed for macronutrients (proximate analysis) and micronutrients, including vitamin C, antioxidant activity, and iron (Fe) content. The results showed adequate levels of energy, protein, fat, and carbohydrates. Micronutrient analysis indicated 3.31 mg of iron, 53 mg of vitamin C, and 56.21% antioxidant inhibition per 100 g of product. Texture evaluation using origami-style folding confirmed good flexibility and tear resistance, supporting its function as an edible paper. Overall, the product retained substantial nutrients and could be folded into origami shapes without losing its structural integrity. This innovation has the potential to increase vegetable intake in children and improve dietary quality during early childhood.

Abstract

Yellowstripe Scad (Selaroides leptolepis) has potential as a fortificant to enhance the nutritional quality of crackers. The incorporation of yellowstripe scad whole fish powder not only improves the nutrient content but also reduces processing waste. Fish-based crackers can serve as dietary food products, nutrient-dense snack alternatives, and supplementary foods to support stunting prevention. This study aimed to evaluate the nutritional composition (moisture, lipid, dietary fiber, protein, and ash content) and physical quality (texture) of fish crackers. The experiment was designed using a Completely Randomized Design with a single factor, namely, the addition of yellowstripe scad whole powder (SFF) at six levels: 0, 3, 6, 9, 12, and 15%. The data obtained were analyzed using Analysis of Variance, followed by Duncan’s Multiple Range Test to determine significant differences. The results revealed that the addition of yellow stripe scad whole powder significantly affected (p<0.05) the physicochemical properties of the yellow stripe scad crackers. Crackers with 15% yellowstripe scad whole powder exhibited the highest protein, lipid, and ash contents of 18.5, 8.97, and 8.97%, respectively. Meanwhile, the addition of 3% yellowstripe scad whole powder produced crackers with the most desirable moisture content, dietary fiber, and texture characteristics of 3.59%, 3.87%, and 1,101 N/cm², respectively.
