Study on the optimization of spray drying process for Areca taro powder with microcystalline cellulose

Starch is a product of intensive processing of agricultural products. During the processing of plant starch, nutrients such as protein, dietary fiber, and minerals are removed. In addition to nutritional imbalance, rich nutrients have an impact on the environment. The object of research is Areca taro, a starch-rich agricultural product. The research aims to use spray drying technology to obtain a whole betel nut taro powder for food processing, such as sausages and noodles. The taro is used as a raw material, and the whole taro flour is obtained after peeling, cutting, crushing with water, and spray drying. Using single factor and orthogonal experiment to optimize the spray drying process parameters and embedding agent of taro powder, and then analyze its physical and chemical properties. The results show that adding 0.01 % Xanthan gum+0.12 % Microcrystalline cellulose (embedded agent) to the taro emulsion can increase the extraction rate of taro flour, speed up the drying speed, and prevent sticking to the wall. The best process of spray drying: the speed of atomizer was 16000 r/m, the wind temperature was 200 °C, the material liquid concentration was 28.00 % and the feeding rate was 75 mL/min. The taro powder produced by this process has better liquidity, light purple color, smooth texture, and strong flavor of taro. Product parameters: powder fluidity was 13.9 cm, extraction rate was 15.36 %, water activity was 0.416, chromaticity parameters were 19.73 (L* value), 2.96 (a* value) and 3.25 (b* value), bulk density was 0.44 g/mL. This technology can provide data support and reference for food processing companies. The taro whole powder would be widely used as food ingredients in future.

PENGEMBANGAN BROWNIES KUKUS TEPUNG TALAS-KECAMBAH KACANG HIJAU DAN UBI UNGU KUKUS (TALAHIBU) UNTUK IBU HAMIL KURANG ENERGI KRONIK (KEK)

Background: The prevalence of pregnant women with a risk of Chronic Energy Deficiency (CED) is quite high (24.2%). CED in pregnant women requires additional feeding interventions (PMT). Brownies enriched with taro flour–mung bean sprouts and purple sweet potato (TALAHIBU) were chosen as it is an energy-dense product and expected to have preferred organoleptic value and energy as PMT. Objectives: To determine the phenolic antioxidant content of the best TALAHIBU formula and to determine the serving size of TALAHIBU. Methodology: This factorial experimental study used a randomized block design (RBD) with 2 factors, consisting of taro flour-mung bean sprout proportion and the percentage of added fine steamed sweet potato. Organoleptic variable analysis used Friedman test continued with 5% Multiple Appeal Test. The best treatment combination was chosen, continued with Proximate and phenolic test then energy calculations. Results: The best treatment was TALAHIBU G2J2 with water content of 23.94% BW; ash content 3.16% bb; fat 25.7% BW; carbohydrates 45.57% bb; protein 1.63% bb; energy 419.83kcal; and phenolic antioxidant 19,1 mg/g. Conclusion: The best product TALAHIBU is suitable PMT for pregnant women with CED by serving 5 slice brownies per day.

Physical quality of chicken patties containing red beans (Vigna angularis) with different filler levels of taro meal

This research aims to evaluate the use of different filler levels of taro meal on the physical quality of chicken patties containing red beans (Vigna angularis). Patties produced from chicken meat with the ratio of red bean flour and taro flour as filler substitution for tapioca flour are 15:0 (CP0), 15:3 (CP1), 10:0 (CP2), 10:3 (CP3), 5:0 (CP4), and 5:3 (CP5). The analysis showed a significant difference in the tenderness (P<0.01), the value of pH, cooking loss, and water holding capacity (P<0.05) of patties. The addition of taro flour can increase the tenderness value of chicken patties. Reducing the amount of red beans resulted in a decrease in the pH value of chicken patties, but the increase in the use of taro meal did not result in a difference in the pH value. The highest cooking loss was achieved with the use of 5% red beans without taro meal. The highest water holding capacity of patties produced was obtained with a ratio of red bean and taro meal of 5:3. The conclusion is that adding 10% red beans and 3% taro flour red beans increased the physical quality of chicken patties and can be accepted by consumers.

IMPACTS OF MORINGA OLEIFERA LEAF POWDER (MLP) ON THE PROTEIN CONTENT AND ENERGY VALUE OF COLOCASIA ESCULENTA (TARO) PORRIDGE: A TRADITIONAL INFANT FOOD IN GUINEA

Moringa oleifera leaf powder (MLP) has exceptional nutritional properties due to its high content of micronutrients, fatty acids, and especially protein. This makes it a suitable ingredient for the fortification of taro flour. Taro is a high-energy product but low in protein and fat, which weanling children need for their normal development. This study aimed to evaluate the protein-energy contribution of MLP powder in infant taro porridge. Three fortified taro porridges named FTP10% (Taro + 10% of Moringa), FTP15% (Taro + 15% of Moringa) and FTP15% (Taro + 15% of Moringa) were performed. Their analyses indicated significant increases (P<0.05) in crude protein content, energy value and titratable acidity from 0.580 0046% to 1.570 0052%, 82.137 143% to 88.807 1658% and from 0.130 0017g/100g to 0.380 0010 g/100 g respectively. KEYWORDS: Proximal composition, taro porridge, Moringa oleifera.

Effect of Taro (Colocasia esculenta) Enrichment on Physicochemical and Textural Properties of Cake

Taro is a plant widely produced in tropical areas for its underground corms and it is used mainly as a vegetable. Its physicochemical, sensory properties and health benefits led to its use in value-added products. The cake is a high value-added bakery product and it needs a lower amount of gluten protein, therefore, taro flour (TF) was supplemented in wheat flour (WF) at different levels (10, 20, 30 and 40%). In connection with this, the incorporation of taro flour into wheat-based products has been reported to increase their nutritional and textural quality. The taro-supplemented cake showed higher mineral and fiber content, however, reduced caloric value. It was observed that taro supplementation reduced gluten and protein content and had higher oil and water binding capacity, therefore suitable for cake preparation. Taro cake had improved texture and sensory characteristics in comparison to wheat cake. It can be concluded that addition of taro for cake preparation improves nutrition and quality characteristics, therefore, it can be recommended to use taro for cake preparation.
