PENGARUH VARIASI SUHU DAN WAKTU PENGERINGAN PADA PEMBUATAN ENZIM PAPAIN DARI EKSTRAK DAUN PEPAYA

Papaya leaves have long been known as leaves that contain meat tenderizers. Papaya leaves can soften the meat because it contains papain which is one of the protease enzymes. In the fresh papaya leaves there is sap which contains 5.3% papain. Meat tenderizer in powder form is more practical and more durable. One of the papain enzyme powder drying methods that is considered appropriate to be applied in the ginger powder production process is the foam mat drying method. This study aims to examine the foam drying process on papain enzyme activity using tween 80 (foam agent) and maltodextrin as filler to help maintain foam consistency. The drying process was carried out by varying the drying temperature (50oC, 55oC, 60oC, 65oC, and 75oC) and drying time (2 hours, 3 hours, 4 hours, 5 hours and 6 hours). The results of the analysis showed that the highest enzyme activity reached 408.7 U/mL for drying at an operating temperature of 60oC with a time of 2 hours..

Penerapan Teknologi Alat Kristalisasi Dalam Upaya Pengolahan Produk Dalam Pangan Serbuk Herbal Instan di Kelurahan Kereng Bangkirai

One of the ginger rhizome processing technologies is by making instant drink powder. Instant drinks food processed products in powder, practical in presenting and have long-saving power and easily dissolved in hot, cold and warm water. However, making ginger powder is done manually using human power in stirring ginger water until it becomes a powder for a long time, causing the moving process to be unstable. Therefore, the crystallizer tool is designed to help the manual stirring process increase the quality of instant ginger powder products. In Kereng Bangkirai Village, Palangka Raya City, the community service activities were carried out in lectures/socialization/counseling, demonstration tools, leaflet distribution, pre-test / post-test evaluations, and feedback.

Selanjutnya perlakuan terbaik diperoleh pada perlakuan (N3S5) dari jahe merah yang dikeringkan dengan ketebalan irisan 3 mm yang dikeringkan dengan suhu 50oC dengan nilai kadar air 10,05% bb, kerapatan curah 790Kg/m3, sudut curah 43,34o. ABSTRACT Processing red ginger in powder form is one way to preserve the red ginger crop, which has a high moisture content. Processing of red ginger in powder form requires drying of the material so it can remove the water content in the material. In drying a material, the temperature and thickness influence drying. The purpose of this study was to determine the drying characteristics, the physical properties of red ginger powder and the treatment that produced the best dry ginger powder quality with variations in temperature and slice thickness during drying. The design used in this study was a factorial randomized block design (RBD) with two factors and three replications. The first factor is the drying temperature of 50oC, 60oC, and 70oC and the second factor is the thickness of the red ginger slices 1 mm, 3 mm, 5 mm. The parameters observed were moisture content, bulk density, angle of bulk, uniformity index, and rate of reduction in water content of red ginger. The results showed that the interaction between the temperature treatments and the thickness of the slices had a significant effect on the parameters of moisture content, bulk density, angle of bulk, and the rate of reduction in water content of red ginger. The best treatment was obtained in treatment (N3S5) of dried red ginger with a thickness of 3 mm slices dried at a temperature of 50oC with a moisture content value of 10.05% bb, bulk density 790Kg/m3, angle of bulk 43.34o.

Sensory and Physical Characteristics of M. biceps femoris from Older Cows Using Ginger Powder (Zingibain) and Sous Vide Cooking

This study aimed to evaluate the sensory and physical characteristics of zingibain-injected meat combined with sous vide cooking. M. biceps femoris (BF; n = 12) acquired from 6–7 year old Angus cows were cooked using the sous vide method at 65 °C, for 8 h or 12 h, either with ginger powder (GP) injected in a 2 g/L solution in water (treatment) or un-injected (control). The sensory attributes included flavour, juiciness, tenderness, and physicochemical characteristics were Warner-Bratzler shear (WBSF), hardness, total water content (TWC), cooking loss (CL) and collagen content. A significant improvement in tenderness with injection treatment and cooking time was observed, as evaluated through trained sensory panellists, and reduced WBSF and hardness (p < 0.05 for all). The flavour of the meat was not affected by injection treatment or cooking time (p > 0.05), but juiciness and TWC were reduced with longer cooking times (p < 0.01 for both). Soluble collagen increased with injection treatment and cooking time (both p < 0.05). Moderate to high correlations were found between sensory and physical measurements for tenderness and juiciness. The longer cooking time (12 h) with GP injection treatment caused over tenderization of the meat. The soft texture associated with over-tenderization may be suitable for some specialised consumer markets, for instance, the elderly population with chewing difficulties. Improving the eating quality of low-quality meat from old animals through sous vide cooking and the use of ginger proteases may increase the acceptability of lower value beef, potentially enhancing the commercial value of carcasses typically produced in the beef industry.
