1. Reporting the utilization and perspectives of different surface active agents for bread making
Abstract The present study was planned to use surfactants in different concentrations along with varying amounts of shortening in the form of gels to prepare breads. For that purpose, SSL, CSL, PS-60 and GMS were used at level of 0.25, 0.50, 0.75 and 1.00 parts in combination with shortening @ 4.00, 3.75, 3.50 and 3.25 parts. The dough having surfactants gel

2. Acid Hydrolysis of Regular Corn Starch under External Electric Field
The main objective of the present work is the investigation of a new method for starch hydrolysis. For this, we proposed the acid hydrolysis under the action of an external electric field, able to develop a faster reaction than the conventional one. Corn starch with 18% amylose was subjected to a fixed voltage, varying the external electric field application

4. Scanning Electron Microscopy and Crystallinity of starches granules from cowpea, black and carioca beans in raw and cooked forms
Abstract Beans are a vital food for the population around the world because it contains a relatively high amount of protein, vitamins, fiber, and minerals, being an important vegetable source of iron, particularly when combined with ascorbic acid and cysteine. The starch content in the seed is between 45 and 60%. This paper evaluated the granular structure o

5. Ação de indutores de resistência em cacaueiro infectados com Ceratocystis cacaofunesta.
RESUMO O fungo Ceratocystis cacaofunesta é um dos principais problemas na cultura do cacaueiro no Brasil. Para o cacaueiro há poucas alternativas para o controle da doença, sendo que a indução de resistência vem sendo testada como uma possibilidade de controle. Neste trabalho foram utilizados três indutores de resistências em três concentrações di

6. MICROESTRUTURA E PROPRIEDADES DE FILMES DE AMIDO-ÁLCOOL POLIVINÍLICO-ALGINATO ADICIONADOS DE ÓLEOS ESSENCIAIS DE COPAÍBA E CAPIM LIMÃO
AbstractFilms obtained by blends between starch and other polymers and films developed with the addition of an oil can show higher water vapor barriers and improved mechanical properties. Films with starch/PVOH/alginate were obtained by adding copaiba and lemongrass essential oils (EOs). Films without oil served as the control. The microstructure, water vapo

7. Adhesivos tipo poliuretano obtenidos a partir de aceite de ricino y almidón químicamente modificados
This study reports the preparation of polyurethane adhesives using polyols obtained from castor oil modified by a transesterification reaction with pentaerythritol and starch modified by glycosylation. The physical properties of the polyols such as hydroxyl value were determined and the infrared spectroscopic analysis of the polyols reported. The effect of v

8. Propriedades físicas de filmes biodegradáveis à base de amido de mandioca, álcool polivinílico e montmorilonita
The objective of this work was to manufacture biodegradable films based on cassava starch, polyvinyl alcohol (PVA) and sodium montmorillonite (Na-MMT), using glycerol as a plasticizer. These films were characterized according to their microstructure, optical, mechanical, and barrier properties. The combination of starch-PVA-MMT resulted in films with a more

9. Application of cassava starch and carnauba wax-based edible coatings in minimally processed apples / Aplicação de coberturas comestíveis à base de fécula de mandioca e cera de carnaúba em maçãs minimamente processadas
This study aimed at formulating a cassava starch, carnauba wax and stearic acid or palmitic acid - based edible coating, and evaluating their properties and their effects when applied to minimally processed apples. In a first step, Plackett-Burman designs were performed for the following variables selection of coating formulations: cassava starch concentrati

10. Biodegradable foams based on starch, polyvinyl alcohol, chitosan and sugarcane fibers obtained by extrusion
Biodegradable foams made from cassava starch, polyvinyl alcohol (PVA), sugarcane bagasse fibers and chitosan were obtained by extrusion. The composites were prepared with formulations determined by a constrained ternary mixtures experimental design, using as variables: (X1) starch / PVA (100 - 70%), (X2) chitosan (0 - 2%) and (X3) fibers from sugar cane (0 -

11. Citric acid as multifunctional agent in blowing films of starch/PBAT
Citric acid was used as a compatibilizer in the production of starch and PBAT films plasticized with glycerol and processed by blow extrusion. Films produced were characterized by WVP, mechanical properties, FT-IR-ATR and SEM. WPV ranged from 3.71 to 12.73×10-11 g m-1 s-1 Pa-1, while tensile strength and elongation at break ranged from 1.81 to 7.15 MPa and
