Potential development and utilization of sweet potato flour as a raw material for the food industry

Sweet potato (Ipomoea batatas) is one type of tuber that has an important role in food diversification programs. Each 100g of sweet potato contains 27.9 g of carbohydrates, 7000 SI of vitamin A, 30 mg of vitamin C, 30 mg of mineral Ca and an energy value of 123 calories. Its carbohydrate content ranges from 64.83 to 66.90% which is a potential energy source to meet basic food needs other than rice. Sweet potato is considered as a raw material for the food industry, because it has good nutritional content, short plant life, and high production. Its vitamin B6 and folic acid is needed to optimize brain work, rich in fiber and complex carbohydrates but low in calories which is very good for diabetics. However, the soft texture of sweet potatoes and the high of its water content make sweet potatoes easy to damage due to mechanical influences. Processing into flour is one of the efforts to preserve sweet potatoes and increase their usefulness. Ingredients composition, drying method, use of chemicals, and steaming process are factors that can affect flour quality, especially its color and functional characteristics. Drying methods that can be used are spray drying, drum drying and oven dryer. The aim of this review is to explore the opportunities and potential of sweet potato flour (SPF) as an industrial raw material for processed food industries in Indonesia. The review method used is the reference collection method, which is taken from several research results related to SPF and its application to food products such as beverages, fructose syrup, noodles, flakes, cookies, ice cream, yogurt, jams, dyes, and others. Through the preservation of sweet potato into flour and its use as industrial raw material, it is hoped that it can increase the diversity of functional foods needed by the Indonesian community.

Changes in the structural and physicochemical characteristics of sonicated potato flour

Ultrasound has been widely used for physical modifications of starch because of its effectiveness and environment friendliness; however, only a few reports have focused on the effect of varying ultrasonic treatments on the physicochemical properties of potato flour. In the present study, ultrasound at varying power levels (200, 300, 400, 500, and 600 W) and time intervals (20, 40, 60, 80, and 100 min) were used to obtain sonicated flour. Sonicated potato flour exhibited a significant (P < 0.05) decrease in blue value and oil holding capacity but an increase in swelling power, water solubility, syneresis rate, and transparency. Moreover, ultrasound decreased the RDS content while increasing RS and SDS contents. Thermal properties demonstrated significant (P < 0.05) increases in T0 (64.39℃–83.52℃) and TC (144.29℃–146.87℃) but a decrease in ΔH of the sonicated flour. SEM revealed wrinkles, less debris, and larger particle size at the surface of the sonicated flour. FTIR profiles of all samples exhibited similar characteristics peaks, but the sonicated flour had a higher R1047/1022 value. Additionally, ultrasound did not affect crystalline patterns, but it increased the crystallinity of the sonicated flour. Our study contributes to the understanding of physicochemical property changes of sonicated potato flour, which could have industrial applications.

Immunomodulatory and Antioxidant Properties of Ipomoea batatas Flour and Extracts Obtained by Green Extraction.

Sweet potato (SP), Ipomoea batatas Lam, belongs to the Convolvulaceae family. It produces edible storage roots. Currently, orange varieties contribute to improving food systems and managing vitamin A deficiency. Processing of this food crop into flour allows better conservation. However, nutrition health data regarding SP flour obtained by green extraction remains scarce. In this study, we therefore explored its phytochemistry and its associated bioactivity potential for human health. We analyzed the nutritional composition of orange flesh sweet potato (OFSP) flour and assessed the antioxidant (free radical scavenging) and immunomodulatory (on inflammatory murine macrophages) properties of the extract. More specifically, we measured the impact of OFSP flour extract on mediators such as Nitric Oxide (NO) and the production of pro-inflammatory cytokines such as Interleukin-6 (IL-6), Tumor Necrosis Factor alpha (TNF-alpha), Monocyte Chemoattractant Protein-1 (MCP-1), and Prostaglandin-E2 (PGE-2). Our results indicated significant fiber, mineral, beta-carotene, and polyphenols content in the extracts, and antioxidant and immunomodulatory bioactivities were also demonstrated with a concentration-dependent inhibition of cytokine production. Taken together, our results suggest that Ipomoea batatas flour could, in addition to being a good source of energy and beta-carotene provitamin A, constitute a food of interest for the prophylaxis of metabolic diseases associated with an underlying low-grade inflammatory state.

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).

The sensory profiles and preferences of gluten-free cookies made from alternative flours sourced from Indonesia

The objective of this study was to identify the sensory characteristics of gluten-free cookies made from alternative flours and to identify the influence of the sensory attributes on liking. Five alternative gluten-free flours of taro, sorghum, mung beans, ground peanut, and sweet potato were used to make the gluten-free cookies in this study. All the alternative flours were locally sourced from Indonesia. In addition, the cookie made from wheat flour was included as a reference for gluten or “normal” cookie. The driver for liking was investigated and liking based on age and gender segmentation was explored. A total of 118 participants (mean age 32.4 ± 13.48 years old, 56% female and 44% male) were involved to identify the sensory characteristics and liking of the different cookie samples using the CATA (Check-All-That-Apply) method. Liking was closely associated with the cookie made from taro flour which is characterized by a buttery and sweet taste, a buttery aroma, and a crunchy texture. This cookie had similar attributes and liking scores with the cookie made from wheat flour. The different age groups influenced liking with the older age group having a significantly higher liking for the gluten-free cookies made from sweet potato (p = 0.027) and ground peanut (p = 0.080) compared to the younger age group. However, no significant differences were found across gender (p> 0.05) for the liking of gluten-free cookies. This study exhibits the preliminary results for the potential to develop gluten-free cookies made from alternative flours locally sourced from Indonesia.

Kinetics of thermal degradation of carotenoids related to potential of mixture of wheat, cassava and sweet potato flours in baking products.

The consumption of foods such as sweet potato and cassava with high levels of carotenoids is a possible solution to reduce vitamin A deficiency. In this study, we evaluated the kinetics of thermal degradation of carotenoids. The content of carotenoids was quantified by high-performance liquid chromatography, first in fresh material, then in flour and finally in bakery products using mixtures of wheat, sweet potato and cassava. The degree of acceptance of the bakery products by children was also assessed through a sensory acceptance test. The study found that the degradation of carotenoid compounds in sweet potato followed first-order kinetics and fitted the Arrhenius equation with correlations of R2 > 0.9. The retention rates of all-trans-β-carotene were 77%, 56% and 48% at cooking temperatures of 75, 85 and 95 °C respectively, during a cooking time of 20 min. The concentrations of all-trans-β-carotene, after baking, for bread, cookies and cake were 15, 19 and 14 μg g-1 db, respectively. In a sensory acceptance test carried out in a school, 47.6% of the boys and 79.2% of the girls rated the cookies made from a mixture of cassava, sweet potato and wheat flour with the indicator I like it a lot. The content of carotenoid compounds was reduced by exposure to high temperatures and long cooking times. The combinations of cooking time and temperature which minimized degradation of all-trans-β-carotene occurred at 75 °C-20 min and 95 °C-10 min. All-trans-β-carotene retentions for bread, cookies and cake were 25%, 15% and 11% respectively. The mixture of wheat, sweet potato and cassava flour can be considered in the development of cookies with positive contributions of all-trans-β-carotenes and with a good acceptance by children between 9 and 13 years old. © 2023 The Authors.

Microbiological and physicochemical properties of fermented and unfermented sweet potato flour

This research accesses the suitability of using processed flours from fermented and unfermented yellow-fleshed sweet-potato as alternative flour based on their physiochemical and microbiological properties. Raw yellow sweet potato tubers were obtained from a local Nigerian market and processed into fermented and unfermented sweet potato flours. Their microbiological and physiochemical (proximate and functional) properties were analyzed using standard methods. The microbiological results identified six bacterial genera; (Bacillus, Klebsiella, Micrococcus, Staphylococcus, Lactococcus, and Enterobacter) and five fungal genera (Aspergillus, Penicillium, Mucor, Candida, and Saccharomyces). Bacillus and Aspergillus spp. were the most dominant bacterial and fungal genera respectively. The physiochemical result reveals that fermenting sweet potato flour resulted in improved protein, moisture content, and water and oil adsorption capacities compared to the unfermented flour. The pH also decreased from 8.8 to 5.0 after 72 h of fermentation. Most of the microorganisms isolated are associated with plants, water, environment, and fermentation, they are generally recognized as safe (GRAS) organisms and their potentials can be further exploited in the food industry. These findings highlights the potentials of incorporating fermentation techniques in enhancing the nutritional and techno-functional attributes of sweet potato flour as a healthy alternative gluten-free flour-based staple diet.

Potato flour content determination of potato–wheat flour mixture based on hyperspectral imaging

SummaryPotato–wheat flour mixture (PWFM) has important significance for the development of potato staple food products. However, conventional chemical methods are unable to detect the content of potato flour. Hyperspectral imaging (HSI) technology combined with chemometrics was investigated to predict the feasibility of potato flour content in PWFM. In this study, seven pretreatment algorithms were performed to process the raw spectral data. The results showed that the standard normalised variables (SNV) to establish a partial least square regression (PLSR) model had the most predictive accuracy with the determination coefficient of prediction () of 0.9729. The characteristic wavelengths of raw spectral information were extracted using three algorithms to reduce the model complexity. Eventually, the extracted characteristic wavelengths of potato flour content combine with SNV to establish PLSR, principal component regression (PCR) and support vector regression (SVR) models. The results revealed that the optimal model was SNV‐competitive adaptive reweighted sampling (CARS)‐PLSR with the values of of 0.9853. These results showed that HSI determination of potato flour content in PWFM was feasible and provided a non‐destructive method.

Innovative Ingredients Fortified Nutrients Enriched Biscuits and Cookies: Quality and Sensory Analyses

Abstract:Global suffering from COVID-19 has necessitated augmenting the immunity systems of humans through consumption of macro-micro-nutrients and antioxidant-enriched fortified foods. In this article, fortifications of popular bakery products, viz. biscuits, cookies, have been reviewed, encompassing the novel fortifying ingredients and innovative methods employed with an emphasis on the overall enrichment in the final product quality. A few notable features concerning novel fortified biscuit and fortified cookie have been decisively summarized. Wheat flour blended with 40% sesame-cake flour resulted in a fortified biscuit possessing higher protein (16.6%), crude fat (16.95%), and dietary fiber (8.2%) with acceptable sensory characteristics. About 9% toting up of chicken-eggshell dried-powder could result in high Ca content in biscuits with customary changes in texture and sensory properties. A remarkable 5% addition of bee pollen to wheat flour appreciably improved the nutrient compositions (carbohydrate 65.18%, protein 7.32%, and total dietary-fiber 1.47%) along with high polyphenol and antioxidant potentials. Notably, mixing fish fillet protein concentrate with wheat flour could yield enhanced nutritional content (protein 14.63-19.52%, fat 16.2-16.5%), as well as augmented amino acids. Remarkably, wheat flour fortified with fermented jack bean flour resulted in an overall fortified biscuit with substantial carbohydrate, crude protein, fat, fiber, ash, and appreciable macro-micro mineral contents and sensory characteristics. Innovative fortified cookies were made by blending wheat flour or Brewer’s spent grain flour with one or more ingredients, e.g. full fat soya, mushroom, cardamom powder, moringa leaves, coconut, sweet potato flour rendering amplified values of nutrients, superior physical properties, increased mineral and flavonoid contents and organoleptic qualities.
