O objetivo deste trabalho foi estudar as características físicas e químicas da farinha de berinjela pura e em combinação com farinha de trigo. A farinha de berinjela apresentou elevado teor de fibra alimentar total e alta quantidade de proteína, de cinzas e de açúcares totais. Maior concentração de farinha de berinjela em misturas com a farinha de trigo aumentou significativamente os teores de proteína, de sais minerais e de fibra alimentar total das farinhas mistas. O alto teor de fibra alimentar da farinha de berinjela permite apontá-la como alternativa para uso em mistura com farinha de trigo na elaboração de produtos de panificação (biscoitos, pães e massas alimentícias). Maior quantidade de farinha de berinjela na farinha mista amplia a capacidade da mistura em absorver água, podendo aumentar o rendimento da massa em produtos de panificação. A farinha de berinjela é facilmente obtida na granulometria da farinha de trigo, facilitando sua homogeneização. WHEAT AND EGGPLANT MIXED FLOUR: PHYSICAL AND CHEMICAL CHARACTERISTICS Abstract The aim of the present work was to study the physical and chemical characteristics of eggplant flour and its combination with wheat flour. The eggplant flour presented high total dietary fiber content and high protein, ashes and total sugars contents. Higher concentration of eggplant flour in mixtures with wheat flour significantly enhanced protein mineral salts and total dietary fiber content of the mixed flours. The high dietary fiber content of the eggplant flour allows to designate it as utilization alternative in mixture with wheat flour in the elaboration of bakery products (cookies, breads and pasta). Greater quantity of eggplant flour in the mixed flour enlarges the mixture capacity to absorb water, being able to enhance the mass yield in bakery products. The eggplant flour is easily obtained at particle size similar to wheat flour, facilitating its homogenization.

In this work we evaluated the variability in fiber content and physical and chemical parameters of byproducts from orange juice extraction. Five different treatments and two drying methods were evaluated. The results indicate that drying by lyophilization was better than that drying in an oven. The pH ranged from approximately 3.47 to 3.96. The variation in moisture values was 9.22% ± 0.02 to 18.48 ± 0.52%. The total dietary fiber content in the resulting flours ranged from 42.44% to 62.74%. The soluble and insoluble dietary fiber contents differed among the samples, ranging from 5.04% to 19.95% for the first fiber type, and 23.96% to 57.70% for the second. In conclusion, three treatments, associated with freeze-drying, showed promising results in the development of fiber-rich product. However, some modifications are needed, as well as further analysis, to guarantee the benefits of these products for human health. This study contributes to the possible application of industrial byproducts.

ABSTRACT: Soursop is a well-appreciated tropical fruit, both in natura and in the form of juices and nectars. Despite its wide acceptance, there is lack of its use in the preparation of other products, such as alcoholic beverages. The objective of this study was to prepare soursop liquors by varying the concentrations of pulp and sucrose syrup with different contents of total soluble solids and to evaluate the effects of these on the physical and chemical characteristics of the beverages. In the production process, the pulp (300, 400 and 500 g) was macerated with distilled alcohol for 20 days, after which it was filtered, added to the syrup (50, 60 and 70 °Brix), bottled in polyethylene bottles and subjected to an accelerated aging. All drinks resulted in alcohol levels (15.25 to 16.69% v/v) and total sugars (12.63 to 17.97%) in accordance with the standards required by law. The experiments made with the lowest concentration of pulp showed the highest yields (84.17 and 85.25%). First-order models with interactions and 95% confidence intervals were obtained. The pulp consisted of the most significant factor, influencing the largest number of responses (yield, alcohol content, dry residue, titratable acidity, titratable acidity/soluble solids ratio and luminosity). The larger coefficient of determination (R2) values were found in the models adjusted to the data of yield, dry residue, total soluble solids, titratable acidity and total sugars, which were significant and predictive, showing values greater than 0.97.

Abstract Grape pomace is a rich source of dietary fibers and phenolic compounds; it has been added to bakery products to enhance their dietary fiber content and antioxidant activity. Nevertheless, the Insoluble Dietary Fiber (IDF) content of grape pomace is significantly higher than the Soluble Dietary Fiber (SDF) content, the IDF/SDF ratio of bakery products was much higher than the recommended value of 3:1 from the dietetic associations. In this research, grape pomace was treated with cellulase preparation to partially convert IDF to SDF. The appropriate conditions of the cellulolytic treatment were as follows: initial moisture content of grape pomace of 7.5 g water/g dry basis, cellulase concentration of 6 U/g dry basis and treatment time of 1 h. Under these conditions, the SDF content increased by 20% and the IDF/SDF ratio decreased by 23.2%. Then, the enzyme-treated grape pomace (ETGP) and untreated grape pomace (UGPM) were separately mixed with wheat flour for cookie formulation; the grape pomace ratio was 20% of the composite flour weight. The use of ETGP or UTGP significantly improved the content of total, insoluble and soluble dietary fiber, total phenolics, anthocyanin of cookies as well as their antioxidant activity measured by DPPH and FRAP assays. Cookies supplemented with ETGP or UTGP had increased hardness and reduced brightness. The enzymatic treatment of grape pomace did not affect the total dietary fiber and antioxidant activity of cookies; however, their IDF/SDF ratio decreased to 12% and the value of 3.7 was close to the recommended ratio from the dietetic associations. Furthermore, the preference scores of ETGP added cookies and UTGP added cookies were higher than that of the control cookies without grape pomace addition.

The objective of research were to determine the physical and chemical characteristics, and organoleptic of steamed cake with grated cassava as an ingredient substitute for wheat flour. Research used a Non Factorial Complety Randomized Block Design (RALNF) with 5 level of treatments and 3 replication. Level of treatments research : A (wheat flour 0% and grated cassava 100%), B (wheat flour 20% and grated cassava 80%), C (wheat flour 40% and grated cassava 60%), D (wheat flour 60% and grated cassava 40%), E (wheat flour 80% and grated cassava 20%), and F (wheat flour 100% and grated cassava 0%). Results showed that steamed cakes with added grated cassava had significantly effect on the texture, moisture content, lightness, and hue but ash content and chroma not significant. The average value of texture, lightness, chroma, hue, moisture content and ash content of steamed cake is 618,33-1.273,47 gf; 65.30-75.20%; 32.33-38.03%; 83,27-86,87o; 29.84-40.41%; and 0.39-0.79%. Carbohydrate, protein, crude fiber, and HCN of steamed cake with grated cassava 80% and 40% were 44.88% and 49.9%; 3.37% and 2.90%; 3.94% and 2.91%, 1.72 and 1,14 mg /100 g respectively.

The mocaf flour also known asmodified cassava flour is flour that is modified byusing microbial fermentation techniques.It has similar physical and chemical characteristics that could substitute wheat flour. This study aims to obtain the composition or formula inmaking batik–patterned cookies as well as attaining public acceptance of the product.A series of four combinations of mocaf and wheat flour were formulated and an acceptance test was carried out on 30 panelists inYogyakarta within AugustandOctober 2019.The findings disclosed that the cookie sampleX3with the combination of 150grammocaf flourand 50gramwheat flour had the highestvalue (M = color: 3.37; aroma: 3.13;texture: 3.20;and taste: 3.33).This study is the first toassess the acceptance rate of batik –patterned cookiesusing mocaf flour. The significant results deepen our understandings of the demand of the consumers in order to increase selling value thus indirectly promoting the batik motifs to the consumers.
