Soluble and insoluble dietary fiber in cereals and legumes cultivated in Chile

Insoluble, soluble and total dietary fiber (DF) were determined in 35 varieties of certified whole seeds (without processing) of cereals (rice, oat, rye, and wheat) and legumes (pea, cowpea, beans, chikpea, lentil and lupine). The enzymatic method of Asp, Johansson and Siljestrom was used, with modifications in relation to time of incubation with alpha amylase, filtration system and volumes of the filtrates. Results were expressed as g/100 g dry weight. Total DF for cereals showed a range from 10.1 (wheat var. Chasqui) to 22.2 (rice var Quella). Rye, var. Tetra Baer and oats var. Pony Baer presented the highest soluble fiber content (3.3 and 3.9, respectively). In legumes, total DF fluctuated between 12.7 (pea, var. yellow) and 36.6 (lupine, var. Multolupa). Bean, var. Pinto INIA and lupine var. Multolupa presented the highest soluble fiber values (5.8 for both). Based on the results of this research work, it might be concluded that great variation exists in regard to the amount of total soluble and insoluble DF in cereals and legumes, a fact which impedes generalization as to its content in each food item.     

Chemical composition and mineral content of legumes and cereals produced in Northwestern Argentina

Different varieties of bean (Phaseolus vulgaris), corn (Zea mayz), lentil (Lens sp), soya (Glycine max) and wheat (Tricticum sp) were analyzed in order to obtaining data of chemical composition and content of minerals to contribute to the International Food Data System INFOODS in the elaboration of Regional Food Composition Tables and to evaluate the quality of grains. The selected varieties were the ones produced in the northwestern region of Argentina. The beans were divided in five groups, according to their statistical similarity. The pallares variety is the one that presents bigger content of Cu (2.42 mg/100 g), Fe (76.03 mg/100 g) and Zn (6.08 mg/100 g). The samples of corn were divided in three groups, according to their statistical similarity. The leales yellow corn has bigger content of Zn (3.16 mg/100 g) that the other varieties of the region. The 8 rayas white corn is the one that presents bigger content of Fe (11.48 mg/100 g), while the pisingallo yellow corn is that of bigger content of Cu (1.21 mg/100 g).     

Elaboration, by linear programming, of new products from cereals and legumes

The differing contents of essential amino acids in cereals and legumes bring about an overall increase in protein quality when these foods are consumed together. This study describes a least cost formulation method for preparing products based on cereals and legumes using linear programming. The mixture was formulated under different constraints; from a nutritional standpoint, a given amino acid pattern, and another one on a technological feasibility constraint, which depends on the type of product to be elaborated. From the formulation based on wheat, chick-pea, sorghum, and soybean flours, three products were developed: bread, tortillas and cookies; from these, bread was selected for further evaluation. The product was chemically evaluated by proximate analysis composition, and amino acids were determined by HPLC. Biological evaluation was performed by the PER and RPV methods, obtaining a PER of 1.69 for the developed bread product, and of 0.68 for the control bread. The RPV for the developed product was 64.31% of lactoalbumin and 23% for the control bread, which represents an increase of 41%. The sensory evaluation results did not indicate significant differences in taste, texture, color or overall acceptability of the developed bread product as compared to the control.     

Computer aided product design tool for sustainable product development

A computer aided product design (CAPD) tool is proposed that finds mixtures matching target properties. Genetic algorithm crossover and mutation operators are completed with insertion or deletion operators adapted for side branches. A new substitution operator is devised for cyclic molecules. The mixture fitness is evaluated by a weighted sum of property performances. Molecules are represented by molecular graphs. They are split into molecular fragments which are built from polyatomic groups. Molecules or molecular fragments can be fixed, constrained or left free for building a new molecule. Building blocks are chemical functional groups or bio-sourced synthons. A specific coding of hydrogen-suppressed atoms is devised that can be used with various property estimation models where atom connectivity information is required. Illustration is provided through three case studies to find levulinic, glycerol and bio-based derivatives as substitute for chlorinated paraffin, methyl p-coumarate ester solvent and blanket wash solvent, respectively.     

Management systems for creative product development

A consideration of various routes for creative product development has suggested that ambidextrous methods of management are most appropriate. This has led to an examination of how group vs. individual processing affects the individual engaged in creative product development. Based on certain scenarios and field experiences supported by the literature, it is postulated that participation in innovating groups can have positive as well as negative impacts. Thus, creativity may be facilitated or impeded, depending on the quality and duration of group involvement. This analysis suggests that management approaches should permit certain contingencies to inject variety into experiences of individuals responsible for new product development. A flexible management style allows for stimulation within groups as well as satisfaction of self-actualization needs of individuals engaged in the creative process.

Ontological informatics infrastructure for pharmaceutical product development and manufacturing

Informatics infrastructure plays a crucial role in supporting different decision making activities related to pharmaceutical product development, pilot plant and commercial scale manufacturing by streamlining information gathering, data integration, model development and managing all these for easy and timely access and reuse. The foundation of such an infrastructure is the explicitly and formally modeled information. This foundation enables knowledge in different forms, and best manufacturing practices, to be modeled and captured into tools to support the product lifecycle management. This paper discusses the development of ontologies, Semantic Web infrastructure and Web related technologies that make such an infrastructure development possible. While many of the issues addressed in this paper are applicable to a wide spectrum of molecular-based products, we focus our work on the development of pharmaceutical informatics to support Active Pharmaceutical Ingredient (API) as well as drug product development as case studies to illustrate the various aspects of this infrastructure.

Pressure relief-dipping-microwave assisted polymerization of melamine-l-aspartic acid resin at activated carbon for purification of l-threonine fermented crude product

L-threonine (L-Thr) obtained by fermentation often contains vestigial hydrosoluble Pb(Ⅱ), Fe(Ⅱ), L-glutamic acid (L-Glu) etc., which affect the product quality. Poly melamine and L-aspartic acid (L-Asp) resin functional coconut shell activated carbon composite (PMA/AC) was prepared by a pressure relief-dipping-microwave assisted polymerization method for the simultaneous removals. The adsorption capacities of Pb(Ⅱ), Fe(Ⅱ) and L-Glu could reach to 82.34 mg·g^-1, 57.82 mg·g^-1 and 102.58 mg·g^-1 at conditions of pH 5.0, 45℃ and 4 h with an initial concentration of 0.01 mol·L^-1, respectively. The present PMA/AC was successfully used to the simultaneous removals of vestigial Pb(Ⅱ), Fe(Ⅱ) and L-Glu from the fermented crude product solution of L-Thr. Moreover, the PMA/AC was carefully characterized by FE-SEM, IR et al. analysis techniques, the results show that abundant PMA particles evenly distributed at the inner and outside surface of AC with a size of (50±20) nm.     

基于KPLS模型的间歇过程产品质量控制

针对间歇过程所具有的非线性特性,提出了一种基于核偏最小二乘(KPLS)模型的最终产品质量控制策略。利用初始条件、批次展开后的过程数据以及最终产品质量建立了间歇过程的KPLS模型;采用基于主成分分析(PCA)映射的预估方法对未知的过程数据进行补充,实现了最终产品质量的在线预测。为了解决最终产品质量的控制,利用T2统计量确定KPLS模型的适用范围,并作为约束引入产品质量控制问题,提高控制策略的可行性;采用粒子群优化(PSO)算法实现了优化问题的高效求解。仿真结果表明,与基于偏最小二乘(PLS)模型的控制策略相比,所提出的方法具有更高的预测精度,且能有效解决产品质量控制中出现的各种问题。     

Nutritive value of diets based on tubers and legumes consumed in 3 different proportions

This study was an attempt to determine the nutritional value of diets based on mixtures of manioc and cowpea flours. The proportions analyzed were 87/13, 70/30 and 50/50, respectively. The effect of supplementing these diets with methionine was also investigated. The nutritional value of the diets was evaluated using as a basis the percentage of utilizable protein. Findings revealed that the protein was best utilized when the percentages of manioc and cowpea flours were 50/50, with significant differences observed among the proportions analyzed. In contrast, no significant differences were observed with methionine supplementation to diets of manioc and cowpea flours mixed in the proportion of 87/13. However, when the proportions were 70/30 and 50/50, the addition of methionine induced significant differences, with the highest protein value in both mixtures. It was also observed that the percentage of utilizable protein increased as the proportions of cowpea in the diets also increased.
