The study of the influence of food supplement “Enzo Way 5.02” on the properties of bread and its microbiological indicators

In article results of research of influence of application of technological (TAM) “Enzo Way 5.02” (limited liability company “grain Ingredient”) while softening wheat on physical-chemical, structural-mechanical and microbiological indicators of bread from wheat flour first grade. It is established that the specific volume of the test sample (TAM) was 10 cm3/100 g compared with reference sample (white bread from wheat flour first grade). Analysis of the results of humidity and acidity of bread has shown that TAM does not affect these parameters, however, the porosity in the experimental sample was 3% more than the control. The total deformation in the test specimen more by 24.4%, plastic deformation on 17%, elastic deformation by 40%, relative plastic deformation by 14%, relative elastic deformation at 12%, the coefficient of elasticity by 20.5%. The results of the analysis of microbiological indicators show that TAM “EnzoWay 5.02” reduces the number of bacteria in the bread of a test sample after 3 h after baking at 80% (almost 5 times), and after 72 h 92% (13 times), compared with white bread from wheat flour first grade. Thus the positive influence of using TAM “EnzoWay 5.02” while softening wheat on physical-chemical, structural-mechanical and microbiological indicators bread from wheat flour first grade. It is proved expediency of application of TAM in the production of flour and bakery products.

Influence of food supplementation on the fitness of two biological control agents: a predatory nabid bug and a bollworm pupal parasitoid

Many arthropod predators and parasitoids exhibit either stage-specific or lifetime omnivory, in that they include extra-floral nectar, floral nectar, honeydew or pollen in their immature and/or adult diet. Access to these plant-derived foods can enhance pest suppression by increasing both the individual fitness and local density of natural enemies. Commercial products such as Amino-Feed®, Envirofeast®, and Pred-Feed® can be applied to crops to act as artificial-plant-derived foods. In laboratory and glasshouse experiments we examined the influence of carbohydrate and protein rich Amino-Feed UV® or Amino-Feed, respectively, on the fitness of a predatory nabid bug Nabis kinbergii Reuter (Hemiptera: Nabidae) and bollworm pupal parasitoid Ichneumon promissorius (Erichson) (Hymenoptera: Ichneumonidae). Under the chosen conditions, the provision of either wet or dry residues of Amino-Feed UV had no discernable effect on immediate or longer-term survival and immature development times of N. kinbergii. In contrast, the provision of honey, Amino-Feed plus extrafloral nectar, and extrafloral nectar alone had a marked effect on the longevity of I. promissorius, indicating that they were limited by at least carbohydrates as an energy source, but probably not protein. Compared with a water only diet, the provision of Amino-Feed plus extrafloral nectar increased the longevity of males and females of I. promissorius by 3.0- and 2.4-fold, respectively. Not only did female parasitoids live longer when provided food, but the total number of eggs laid and timing of deposition was affected by diet under the chosen conditions. Notably, females in the water and honey treatments deposited greater numbers of eggs earlier in the trial, but this trend was unable to be sustained over their lifetime. Egg numbers in these treatments subsequently fell below the levels achieved by females in the Amino-Feed plus extrafloral nectar and cotton extrafloral nectar only treatments. Furthermore, there were times when the inclusion of the Amino-Feed was beneficial compared with cotton extrafloral nectar only. Artificial food supplements and plant-derived foods are worthy of further investigation because they have potential to improve the ecosystem service of biological pest control in targeted agroecosystems by providing natural enemies with an alternative source of nutrition, particularly during periods of prey/host scarcity.

The influence of food supplementation on a coastal dune rodent community

AbstractStudies of the rodent community in regenerating coastal dune forest areas north of Richards Bay, South Africa, have indicated that a number of species occupy newly rehabilitating areas. Unstable environmental conditions result in habitat changes, rather than competitive interactions, being the major determinant of rodent community development. This led to the present study, which investigated the effects of supplementary food on rodent assemblages. We attempted to stabilize food availability in order to elucidate some of the mechanisms responsible for the development of the rodent community. By only increasing an existing portion of the resource spectrum, we reduced species diversity, probably through dominance by competitive superior exploiters of the augmented resource. Thus, species diversity decreased with food supplementation, as a result of an increase in the abundance of Mastomys natalensis rather than because of a change in the number of species or the abundance of other species.

SUPLEMENTAÇÃO ALIMENTAR DE CABRAS ANGLO-NUBIANAS NA ÉPOCA CHUVOSA, NA REGIÃO SEMI-ÁRIDA DO NORDESTE BRASILEIRO

Foi realizado um experimento para avaliar a influência da suplementação alimentar na produção de leite de cabras da raça Anglo-nubiana, durante a época chuvosa, na região semi-árida do Nordeste brasileiro. Vinte e quatro cabras foram mantidas em pastagem nativa rebaixada, distribuídas ao acaso, por tipo de parto e produção de leite, em três níveis de suplementação: N0 - sem suplementação, N1 -150 g de concentrado/animal/dia e N2 - 300 g de concentrado/animal/dia. Não houve diferença significativa (p>0,05) entre os níveis de suplementação. A produção de leite foi descrita por uma regressão múltipla em função do período de lactação em semana. A interação semana x níveis de suplementação foi significativa (p<0,01). Os resultados revelam que a suplementação com concentrado, na dose de 300 g/animal/dia, foi a melhor opção para se produzir leite com cabras Anglo-nubianas, durante a época chuvosa.

Influence of food supplementation and/or psychological stimulation on mental development. Giessen-Harvard-ICBF project.

Nutritional supplementation of mothers and psychological stimulation of the child both have a positive effect on physical and mental development during the first year of life. This has been shown in a few hundred mildly malnourished families in the suburbs of Bogota (Colombia).
