The effect of inulin and/or okara flour on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product (FSP) and on probiotic survival under in vitro simulated gastrointestinal conditions were investigated throughout 28 days of storage at 4 °C. Employing a 22 design, four FSP trials were produced from soymilk fermented with ABT-4 culture (La-5, Bb-12, and Streptococcus thermophilus): FSP (control); FSP-I (with inulin, 3 g/100 mL of soymilk); FSP-O (with okara, 5 g/100 mL); FSP-IO (with inulin + okara, ratio 3:5 g/100 mL). Probiotic viabilities ranged from 8 to 9 log cfu/g during the 28 days of storage, and inulin and/or okara flour did not affect the viability of La-5 and Bb-12. Bb-12 resistance to the artificial gastrointestinal juices was higher than for La-5, since the Bb-12 and La-5 populations decreased approximately 0.6 log cfu/g and 3.8 log cfu/g, respectively, throughout storage period. Even though the protective effect of inulin and/or okara flour on probiotic microorganisms was not significant, when compared to a fresh culture, the FSP matrix improved Bb-12 survival on day 1 of storage and may be considered a good vehicle for Bb-12 and could play an important role in probiotic protection against gastrointestinal juices. © 2013 Elsevier Ltd.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Pós-graduação em Alimentos e Nutrição - FCFAR; Okara é o resíduo do processo de produção do extrato hidrossolúvel de soja ou “leite de soja”, cujo valor nutricional tem sido considerado por apresentar proteínas, lipídeos e fibras em quantidades significativas, além de compostos bioativos como as isoflavonas. As grandes quantidades de okara produzidas anualmente no Brasil e demais países geram um problema de eliminação e têm servido apenas para a alimentação de animais. Tal situação pode ser modificada por meio de estudos que demonstrem a viabilidade de sua utilização na alimentação humana. Nesse sentido, a proposta desse trabalho foi desenvolver um “hambúrguer” fermentado com cultivo probiótico, a base de carne de frango e que empregue em sua formulação a farinha de okara. A primeira etapa do projeto teve como objetivo testar a viabilidade da incorporação da farinha de okara. Foram processadas 5 formulações de “hambúrgueres” de frango variando as concentrações de farinha de okara entre 10-50%. Os resultados demonstraram que foi possível a elaboração de “hambúrguer” de frango, fermentado com Lactobacillus acidophilus CRL 1014...

Employing a 2(2) design, four formulations of SY produced from soymilk and fermented with an ABT-4 culture (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12 and Streptococcus thermophilus) were studied: SY-C (control); SY-I (with inulin); SY-O (with okara); SY-IO (with inulin + okara).RESULTSThe addition of okara and the refrigerated storage led to significant differences in the instrumental texture parameters of SY (P < 0.05). Inulin and okara did not affect SY sensory acceptability (P > 0.05), but there was a tendency for higher scores in the presence of inulin. On the other hand, the storage period, particularly at 21 days, was unfavourable regarding the acceptance of the different SY.CONCLUSIONThe results showed that the addition of okara flour and the storage were significant factors to increase firmness of the soy yoghurts. SY acceptability was not affected by the incorporation of inulin or okara. These results suggest that okara...

A composição química do extrato aquoso de soja e de seu subproduto okara foi determinada. Em base seca, para o okara, o teor dos componentes encontrados foi de 2,8% de cinzas, 37% de proteínas, 13% de lipídios, 42,5% de fibras alimentares e 4,7% de carboidratos solúveis. Para o extrato aquoso esses valores foram de 2,4% de cinzas, 33% de proteínas, 17,7% de lipídios, 41,4% de carboidratos solúveis e traços de fibras alimentares. Pães do tipo francês foram adicionados de 0, 5, 10 e 15% de okara seco. Foi realizada a análise sensorial por meio do teste de preferência que demonstrou que os pães contendo 5% e 10% de okara tiveram níveis de aceitação iguais e superiores àqueles contendo 15%. Assim, os pães contendo 10% de okara foram submetidos ao teste sensorial de intenção de compra, revelando média 4,2 numa escala de 1 a 5, ou seja, uma avaliação favorável do ponto de vista comercial. Pães adicionados de 5% e 10% de okara podem ser denominados produtos "fonte" e "ricos" em fibras, respectivamente.

The objective of this research was to test the addition of soymilk residue, also known as okara, to a molded sweet biscuit (MSB). The okara was provided by two soymilk producing companies whose production systems are based on hot disintegration of decorticated (company B) or non-decorticated (company A) soybeans and separation of the soymilk. Okaras A and B were dehydrated in a flash dryer and then ground to a flour (< 200 mesh). The okara flours showed high protein (35 g.100 g-1 dwb), lipid (17 g.100 g-1 dwb), and fiber (17 to 21 g.100 g-1 dwb) contents. The water holding capacity, protein solubility, emulsifying capacity, emulsion stability and isoflavone contents found in flour A were significantly higher (p < 0.05) than in flour B. The formulation of MSB, replacing 30% (w/w) of the wheat flour with okara flour was tested. The results of the physical measurements, brittleness and water activity of the MSB with flours A and B did not differ significantly (p < 0.05) from those of the standard. The color, flavor and overall quality of the MSB with 30% of okara flour B did not differ significantly from those of the standard biscuit, demonstrating its potential for application in confectionery products.

The objective of this research project was to study the drying of soymilk residue in a pneumatic flash dryer, using response Surface Methodology (RSM), and to evaluate the quality of the dried residue. Soymilk residue, also known as okara, was provided by a Brazilian soymilk factory. RSM showed that for a 120 second drying cycle, the lower the residue moisture contents (y) obtained, the higher the recirculation rates (x1), regardless of the air drying temperature (x2), and it could be expressed by the equation y = 7.072 - 7.92x1, with R² = 92,92%. It is possible to obtain okara with 10% of moisture (dwb) under the condition x1=1.25, equivalent to RR = 61%, with air drying temperatures ranging from 252 °C to 308 °C. The dried okara obtained through Central Compound Rotational Design (CCRD) presented a centesimal composition similar to the okara dried in a tray dryer, known as the original okara. There were significant variations (p < 0.05) in the Emulsifying Capacity (EC), Emulsion Stability (ES) and Protein Solubility (PS) between the dehydrated residues obtained. It was concluded that the flash drying of okara is technically feasible and that the physicochemical composition of the residue was not altered; on the contrary, the process promoted a positive effect on the technological functional properties.

The addition of okara flour to an emulsified meat product (Frankfurter type sausage) was evaluated based on the physical, chemical, technological, and sensory characteristics of the final product. Okara, residue from soymilk production, was provided by two soymilk producing companies whose production systems were based on the hot disintegration of the decorticated (company B) or undecorticated (company A) soybeans. The okara was dehydrated using a flash dryer and then ground into flour (>420 µm). However, The okara flours A and B showed approximately the same amount of protein (35 and 40 g.100 g-1 dwb). However, the okara flour A presented higher values (p < 0.05) for all technological functional properties studied (emulsification capacity, emulsion stability, protein solubility, and water hold capacity) than those of okara flour B. The A and B okara flours were used in a frankfurter sausage formulation as substitution of 1.5% and 4% of meat. The results showed that the sausages containing okara flours A and B, as well as the control sausage, were accepted by the sensory panel. Moreover, there were no significant differences (p < 0.05) in the physical (color, objective texture, and emulsion stability) and chemical (pH and proximate composition) measurements of the sausages with and without the okara flour.

Okara is a by-product generated during the manufacture of soymilk and tofu. Wet okara was added to beef burgers at 0%, 20%, and 25%. The effects of okara on certain physicochemical, textural, and sensory properties of reduced fat beef burgers were investigated. The beef burgers formulated with okara (104.0-106.0 kcal/100 g) had 60% less calories than commercial beef burgers (268.8 kcal/100 g). The texture profile analysis showed that the addition of wet okara led to a significant increase in hardness (p < 0.05) and a concomitant reduction in the values of chewiness, springiness, and cohesiveness. Lower sensory scores (p < 0.05) of flavour were observed in the beef burgers containing 25% wet okara. However, the sensory evaluation results showed that juiciness, appearance, tenderness, and overall acceptability of beef burgers formulated with okara did not differ statistically from that of the control (0% okara). Wet okara (20%) can be used as a non-meat protein source in the production of reduced-fat beef burgers without changing their sensory quality.

The aim of this work was to reduce the natural fermentation period of ‘idli’ from the conventional 14 h to 10 h by adding underutilized okara for the preparation of ‘idli’. Black gram was partially substituted with soy residue okara in the ratio of (1:1). After 14 h of natural fermentation, the pH and total acidity of control ‘idli’ batter was 4.51 and 0.64% and that of okara fortified ‘idli’ batter was 4.53 and 0.43%, respectively. The amount of CO2 released by the control and okara fortified batter was 19.7% and 33.6% respectively. The viable count of yeast and mold, lactics and mesophilic bacteria in control & okara batter increased with time reaching 9.00 & 10.34, 8.66 & 7.69, and 8.65 & 9.47 log10 cfu/g, respectively at the end of 10 h of natural fermentation. Okara fortified ‘idli’ was soft and spongy compared to control ‘idli’ .

Okara, soybean waste from tofu and soymilk production, was utilised as a natural antioxidant in soap formulation for stratum corneum application. D-optimal mixture design was employed to investigate the influence of the main compositions of okara soap containing different fatty acid and oils (virgin coconut oil A (24–28% w/w), olive oil B (15–20% w/w), palm oil C (6–10% w/w), castor oil D (15–20% w/w), cocoa butter E (6–10% w/w), and okara F (2–7% w/w)) by saponification process on the response hardness of the soap. The experimental data were utilized to carry out analysis of variance (ANOVA) and to develop a polynomial regression model for okara soap hardness in terms of the six design factors considered in this study. Results revealed that the best mixture was the formulation that included 26.537% A, 19.999% B, 9.998% C, 16.241% D, 7.633% E, and 7.000% F. The results proved that the difference in the level of fatty acid and oils in the formulation significantly affects the hardness of soap. Depending on the desirable level of those six variables, creation of okara based soap with desirable properties better than those of commercial ones is possible.

The study was conducted with the main objective to develop beef burgers with added okara flour and verify the interaction of this ingredient with others, such as textured soy protein (TSP) and fat. The okara flour showed the following composition on a dry basis: 55.50% protein, 21% fat, 3.97% ash and 19.01% carbohydrates. Work development planning was used for simplex centroid mixtures in which the concentrations of TSP, okara flour and fat, ranged between 0 and 8% from 7 formulations. The samples were subjected to burgers developed technological functional analysis (yield, shrinkage, moisture retention, fat retention, absorption water index and absorption oil index), chemical composition (moisture, fat, protein and ash) and also the test of acceptance and purchase intent by sensory analysis. For technological functional properties, the textured soy protein, okara flour and fat influenced significantly (p <0.05) shrinkage, yield and water absorption index. Lower shrinkage values and higher yield values were obtained with the use of soy protein. The absorption water index had the same influences for both protein, as the textured soy protein and okara flour. For moisture retention and fat, only textured soy protein had a significant effect on these variables improves. Regarding chemical composition...

Okara is a biomass generated by the soybean and tofu water soluble extract process. Such biomass has a very important nutritional quality because of the protein content, fibres and bioactive compounds as the isoflavons. It is produced in great amounts by the soybean processing industry as a by-product, although it is a product of low commercial value, it possess on its composition molecules with nutritional and functional potential. The isoflavons are present in the soybean mainly in the combined forms (B-glycosidics, acetyl and molonic) and, in a minor proportion, in the free forms (aglycons). Several studies prove the efficiency of aglycons isoflavons preventing cronicle diseases. Some technologies have been employed for the bioconversion of β-glycosidic isoflavon in aglycons based in the action of enzymes β-glycoside hydrolase synthesized by microorganisms. In this context, the current work has aimed the bioconversion by Saccharomyces cerevisiae r. f. bayanus, trying to improve the okara nutritional quality and biological properties in order to use it as an ingredient in food. The semisolid fermentation has been lead under 28° C per 72 hours. The process was conduction at increase protein and reduction of crude fiber content improving the product digestibility. The fermentation provided a biotransformation of isoflavonscombining aglycons...

O aproveitamento de resíduos industriais tem se tornado muito importante para evitar contaminação do meio e reaproveitar recursos até então considerados desperdícios ou perdas nas indústrias químicas e de alimentos. Na atualidade não se tem um valor aproximado da produção de leite de soja no mundo, mas sabe-se que grandes quantidades de resíduo são geradas pela produção do leite de soja, resíduo este que na literatura se denomina "Okara". Uma forma de aproveitar este resíduo é através de uma operação de secagem. A secagem é uma tecnologia amplamente utilizada pelas indústrias para manter a qualidade e prolongar a vida de prateleira dos produtos devido à diminuição das reações degradativas. Outro resultado da secagem é a diminuição do tamanho e peso do produto, facilitando assim seu transporte e armazenamento. No entanto, ainda hoje, apesar dos avanços tecnológicos nas indústrias químicas e de alimentos, persistem problemas quanto aos métodos específicos adequados para a secagem dos diferentes materiais biológicos, especialmente aqueles usados para alimentação humana. O resíduo de leite de soja é rico em proteínas, fibras e vitaminas, o que o torna de grande importância para diminuir o grande déficit de proteína que tem a população mundial...

The usage of soy is increasing year by year. It increases the problem of financial crisis due to the limited sources of soybeans. Therefore, production of oral tablets containing the nutritious leftover of soymilk production, called okara, as the main ingredient was investigated. The okara tablets were produced using the direct compression method. The percentage of okara, guar gum, microcrystalline cellulose (Avicel PH-101), and maltodextrin influenced tablets' hardness and friability which are analyzed using a D-optimal mixture design. Composition of Avicel PH-101 had positive effects for both hardness and friability tests of the tablets. Maltodextrin and okara composition had a significant positive effect on tablets' hardness, but not on percentage of friability of tablets. However, guar gum had a negative effect on both physical tests. The optimum tablet formulation was obtained: 47.0% of okara, 2.0% of guar gum, 35.0% of Avicel PH-101, and 14.0% of maltodextrin.

The effect of inulin and/or okara flour on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product (FSP) and on probiotic survival under in vitro simulated gastrointestinal conditions were investigated throughout 28 days of storage at 4 °C. Employing a 22 design, four FSP trials were produced from soymilk fermented with ABT-4 culture (La-5, Bb-12, and Streptococcus thermophilus): FSP (control); FSP-I (with inulin, 3 g/100 mL of soymilk); FSP-O (with okara, 5 g/100 mL); FSP-IO (with inulin + okara, ratio 3:5 g/100 mL). Probiotic viabilities ranged from 8 to 9 log cfu/g during the 28 days of storage, and inulin and/or okara flour did not affect the viability of La-5 and Bb-12. Bb-12 resistance to the artificial gastrointestinal juices was higher than for La-5, since the Bb-12 and La-5 populations decreased approximately 0.6 log cfu/g and 3.8 log cfu/g, respectively, throughout storage period. Even though the protective effect of inulin and/or okara flour on probiotic microorganisms was not significant, when compared to a fresh culture, the FSP matrix improved Bb-12 survival on day 1 of storage and may be considered a good vehicle for Bb-12 and could play an important role in probiotic protection against gastrointestinal juices. © 2013 Elsevier Ltd.

This study had the purpose to optimize the specific volume and sensorial quality of breads prepared with different proportions of wheat flour, cassava starch and okara (residue of protein soybean extract). It was used the direct baking process test as the standard and displacement of millet seeds method for specific volume determination. The sensorial analysis was carried out with a trained painel to determine internal and external characteristic, flavor, taste and general grade of elaborated breads. It was applied the test of acceptability of the product optimized after 1, 48 and 96 hours of storage. The specific volume of the bread was higher when smaller proportion of okara was used compared to cassava starch. The bread made with 64.1% of wheat flour, 18.9% of okara and 17% of cassava starch showed specific volume of 4.02 cm3/g, durability and acceptability up to 96 hours after baking. The partial substitution of wheat flour by cassava starch and okara up to 35.9% was viable. The bread obtained had good sensorial quality and specific volume as common sandwich loaf.; O objetivo deste trabalho foi otimizar o volume específico e a qualidade sensorial de pães de forma elaborados com diferentes proporções de farinha de trigo, fécula de mandioca e okara (resíduo do extrato protéico de soja). Utilizou-se o teste de panificação direto para padronização do processo e o método de deslocamento de sementes de painço para a determinação do volume específico dos pães elaborados. Efetuou-se análise sensorial do pão com equipe treinada para a determinação das características externas...
