Abstract

Cactus plants include the stems of dragon fruit plants (Hylocereus sp.), which have nutrients that may be good for human health. These can also be used to make flour because they have the ability to replace wheat flour by up to 25% and have been used in a variety of processed goods, including noodles, yoghurt, cakes, puddings, cookies, and jelly drinks Abundant dragon fruit plant stems will come to waste if not utilized optimally, so it is necessary to process dragon fruit stems by processing them into flour. One of the stages of making flour is drying, which aims to remove the water content of the material to a certain extent to get maximum results and can extend the shelf life of flour. This study aimed to examine the effect of the appropriate drying temperature and slice thickness on the quality of dragon fruit stem flour using a rack-type oven with gas as a heat source. This study used an experimental method with a Completely Randomized Design arranged in a factorial manner consisting of 2 factors: drying temperature and slice thickness. The results showed that the best treatment was at a drying temperature of 60°C with a thickness of 2 mm, as seen from the observations, namely the relative humidity of 28,51 and the fineness modulus of 1,030.

Abstract

LA3 pumpkins are one of the pumpkin variants cultivated in Indonesia, especially in Tegalrejo, Tegalsari Districts, Banyuwangi Regency. LA3 pumpkin production is relatively high, however, its utilization is still low. The waste of LA3 pumpkin pulp is relatively high because farmers only take its seeds. In the origin, during harvest time, LA3 pumpkins are harvested and stored for two weeks before taking its seeds, while the whole pumpkin can be stored for up to three months. After two weeks the pumpkin will be cut open and take their seeds, this action will reduce the pumpkin’s shelf life. However, increasing the LA3 pumpkin’s shelf life can be done by milling the pulp into flour. This study aimed to determine the physical and functional characteristics of LA3 pumpkin flour from the pumpkin that has been stored. In this study, the harvested LA3 pumpkin was stored for both 2 weeks and 2 months, which was repeated 9 times, and then the pumpkin was milled into flour. The data obtained were analyzed by t-test. The values ​​for brightness, viscosity, water holding capacity, and swelling capacity of pumpkin flour stored for 2 weeks had higher values ​​than pumpkin flour stored for 2 months. In contrast, the bulk density, bulk angle, oil binding capacity, and solubility, of flour from pumpkin stored for 2 months had higher values.

Abstract

Sweet potato is the sixth food crop in the world, containing high amounts of carbohydrates with a low glycemic index value. Sweet potatoes are easily damaged during storage, so their shelf life is short. Sweet potato processing into flour is an alternative to sweet potato preservation. Blanching and drying are two processing steps that have an impact on the quality of sweet potato flour. The study aimed to examine the effect of the blanching method and drying temperature on the quality of sweet potato flour. The study used a two-factor Completely Randomized Design. The first factor was the blanching method, which had two levels: steamed blanching and blanching by boiling. The second factor was the drying temperature of 50°, 60°, and 70°C. The results showed that sweet potatoes blanched using boiling and dried at 60°C produced good-quality sweet potato flour based on a yield value of 36.12%, carbohydrates of 70.44%, bulk density of 0.52 g/mL, moisture content of 0.34% and ash content of 3.3%. The assessment results of the color and aroma of sweet potato flour using the scoring method produced a yellowish-white flour color (score of 3.53) and a slightly distinctive aroma of flour (score of 3.46).

Abstract

The objective of this study was to determine the effects of various initial drying methods on the functional properties of sago grub protein concentrates and characterize their functional properties. In this work, a block randomized design was employed to extract sago grub protein concentration using cabinet dryer, sun, and oven drying methods. The variables observed were the foaming capacity, foaming stability, water holding capacity, and fat absorption capacity of the protein concentrate. Results showed that different initial drying methods of sago grub did not affect the foaming capacity, foaming stability, or fat absorption capacity of the resulting protein concentrates. In contrast, the water holding capacity of the protein concentrates was significantly affected by different initial drying methods on sago grub. Various initial drying methods resulted in the protein concentrates having a foaming capacity of 7.5–12.5%, a foaming stability of 3.5-7.5%, a water holding capacity of 1.9–2.35 mL/g, and a fat absorption capacity of 299.12–306.75%.

Abstract

Jember, located in East Java, is renowned for its exceptional production of robusta coffee. The objective of this study was to analyze the physical properties of roasted robusta coffee beans sourced from Argopuro, Jember. The study utilized a fully Randomized Factorial Design incorporating two factors: processing method and roasting intensity. The processing method comprised four levels: natural process, honey process, semi-wet process, and full-wash process. Concurrently, the roasting level treatment consisted of three levels: light, medium, and dark. The observations encompassed the density of green beans, the density of roast beans, and the yield of roast beans. The green beans utilized in this investigation adhered to the quality criteria specified in the Indonesian National Standard (SNI) Grade 2. The research findings indicated that the processing technique had no substantial impact on the density of green beans. Neither the processing method nor the roasting level treatments had a different effect on the density or yield of the roasted beans. Nevertheless, the application of different roasting levels did result in a significant effect on both the density and yield of roasted coffee beans. The natural process approach yielded the maximum green bean density, weighing 365 kg/m3. The dark roast level resulted in the maximum bean density across all processing methods, including the natural, honey, semi-wet, and full-wash processes. The specific values for each method were 735.3 kg/m3, 637.3 kg/m3, 698.4 kg/m3, and 637.5 kg/m3, respectively. Moreover, the light roast level achieved the maximum output of roast beans, reaching 88.83%.
