White rice and common beans are considered staple food in Brazilian diet as an important source of good protein quality and energy [1, 2]. However, few actions are made with the by-products released from the rice milling or bean processing industries, especially at Brazilian market. On the other hand, the industrialized products of easy preparation as well as extruded foods have been developed under relatively low cost [3, 4].
The interest of Latin American countries on producing foods with high quality protein content has increased significantly, once this action may be a viable solution for the mal-nourish problems of their population. Children with this kind of deficiency show serious difficulties of physical and mental development, which can be irreversible in most cases [5].
Biscuits are bakery products of great commercial interest considering their production, commercialization and consumption characteristics, high demand, relatively long shelf life and good acceptability, particularly by children. These products are developed to implement formulations in nutritional terms, especially related to fibre and protein contents and may be an interesting vehicle for beans as an ingredient [6, 7].
It is known that the mixture of cereals and legumes can give a good protein balance and quality. So, the possibility of diversification of their application in food industries may expand and recover their consumption potential, especially for rice and beans.
When rice is milled, around 14% of broken grains are released and have similar composition of head rice but lower commercial value [8]. Most of this by-product, mainly the smallest rice grains, is used to make rice flour or as raw material to elaborate many kinds of foods by extrusion process [9, 10]. In the case of common beans, there is also the formation of broken or split grains, which generally become hard to cook when aging during storage [11] and receive a low price at the market. Due to the anti-nutritional factors present in beans composition, it is necessary to submit the whole or split grains to some thermal process or cooking before consumption or transformation into flour as food ingredients.
These types of flours do not contain gluten, what is interesting to process alternative products for celiac or gluten intolerant people [8]. It is also proved that the mixture of rice and beans give a final protein content of better biological quality with an important amino acids balance, once the lysine amino acid that lacks in rice is present in beans, while sulphur amino acids present in rice can supply the beans deficiency. Besides, the combination of rice and beans provides a good source of several other nutrients [2].
Recently this concern has been increasing in the country since other successful examples can be observed in different parts of the world and our consumers are becoming more demanding for food diversity and quality. Extrusion cooking technology is increasingly being used for the development of food ingredients in order to promote the use of industrial wastes [12, 13].
In order to utilize valuable components of the broken rice and the aged split bean grains, which have low commercial value, to produce different bakery products, this study aimed to investigate the addition of a rice and black bean pre-gelatinized flour by extrusion on cookies formulations, composition and acceptability.
