ABSTRACT

Este trabalho teve como objetivo o desenvolvimento de caldos de peixe compactados, visando o aproveitamento de resíduos de piscicultura de Pacu (Piaractus mesopotamicus), que são matérias-primas de baixo custo e alto valor nutricional. Quatro tratamentos (P1, P2, P3, P4) foram desenvolvidos, utilizando dois tipos de processamentos mecânicos (moedor e despolpadora) e dois tipos de secagem (estufa e liofilizador). Análises sensoriais e microbiológicas foram realizadas. Todos os caldos elaborados estavam de acordo com os padrões microbiológicos e não se diferiram quanto ao teste de aceitação da análise sensorial, que variou entre "gostei ligeiramente" e "gostei moderadamente", e na intenção de compra o resultado foi entre "talvez compraria/ talvez não compraria" e "possivelmente compraria". A produção de caldos compactados como um novo produto utilizando resíduos de peixe como matéria-prima é viável, pois agrega valor ao subproduto e colabora com a redução do impacto ambiental.


This work aimed at the development of fish bouillon cubes, targeting the use of waste fish Pacu (Piaractus mesopotamicus), which are the raw materials of low cost and high nutritional value. Four treatments (P1, P2, P3, P4) have been developed using two types of mechanical processes (grinder and fish pulp machine) and two types of drying (freeze drying and oven). Microbiological and sensory analysis were performed. All fish broth cubes were prepared according to the microbiological standards and do not differ with respect to acceptance testing of sensory analysis, which ranged between "like slightly" and "like moderately", and purchase intent between the result was "maybe buy / maybe not buy "and" possibly buy. The fish broth cube as a new product using fish waste as raw material is feasible, therefore, adds value to byproduct and contributes to reducing the environmental impact.

ABSTRACT

RESUMO O uso de esterco bovino é de suma importância para os agricultores familiares que produzem coentro na região de Mossoró-RN, pois esse insumo é amplamente disponível e utilizado pelos agricultores. Objetivando-se avaliar o Rendimento do coentro fertilizado com esterco bovino em diferentes doses e tempos de incorporação ao solo foi conduzido um experimento no período de setembro a novembro de 2011, na Fazenda Experimental Rafael Fernandes, da Universidade Federal Rural do Semi-Árido - UFERSA, Brasil. Os tratamentos consistiram da combinação de quatro doses de esterco bovino incorporadas ao solo: 15,0; 30,0; 45,0 e 60,0 t ha-1 em base seca, com quatro tempos de incorporação: 28; 49; 64 e 80 dias antes da semeadura do coentro - DAS, mais um tratamento controle (ausência de adubação). O delineamento experimental utilizado foi em blocos completos casualizados com os tratamentos arranjados em esquema fatorial 4 x 4 + 1 com 3 repetições. A cultivar de coentro utilizado foi a Verdão e as variáveis determinadas foram altura e número de hastes por planta e rendimento de coentro. O coentro respondeu à aplicação de esterco bovino, produzindo rendimentos máximos de 6453 e 6349 kg ha-1 de massa verde, com a dose de 60 t ha-1 e aos quarenta e seis dias de incorporação antes da semeadura, respectivamente.


ABSTRACT The use of manure is very important to family farmers who produce coriander in the region of Mossoró-RN, because this input is widely available and used by farmers. Aiming to evaluate the yield of the coriander fertilized with manure at different doses and incorporation times in the soil, a trial was conducted from September to November 2011, at the Experimental Farm Rafael Fernandes in the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró-RN, Brazil. The treatments consisted on the combination of four levels of manure incorporated into the soil: 15.0; 30.0; 45.0 and 60.0 t ha-1 at dry basis, with four incorporation times: 28; 49; 64 and 80 days before the coriander"s sowing - DAS, plus a control treatment (without fertilization). The experimental design was a randomized complete block with treatments arranged in a 4 x 4 + 1, with three replications. The coriander planted was the "Verdão" and the specific variables were height and number of stalks per plant and yield of the coriander. The coriander responded to the application of the manure, producing maximum yields of 6453 and 6349 kg ha-1 of fresh mass, with the dose of 60 t ha-1 and at forty-six days of incorporation before the sowing, respectively.

ABSTRACT

Aim: This study investigated the microbiological, physicochemical and antinutritional properties of three varieties of fermenting melon seeds namely: Citrullus vulgaris (Schrad), Citrullus colocynthis (L) and Cucumeropsis mannii (Naud) for ogiri production. Methodology: Ogiri was produced from these three varieties of melon seeds following the traditional fermentation process while online monitoring was used to evaluate microbial hazards using standard microbiological techniques. Physicochemical and antinutritional properties were determined using standard methods. Results: Bacterial counts ranged from 7.0 x 103 cfu/g to 2.4 x 104 cfu/g for Citrullus vulgaris, 3.2 x 105 cfu/g to 3.7 x105 cfu/g for Citrullus colocynthis and 8.7 x 106 cfu/g to 9.1 x 106 cfu/g for Cucumeropsis mannii. Some of the isolated microorganisms from the fermenting melon seeds include Lactobacillus species, Bacillus species, Aerococcus viridans, Staphylococcus aureus, Micrococcus luteus, Aspergillus niger, Penicillium species and Fusarium eguseti. Cucumeropsis mannii had the highest crude fibre and protein (12.7 and 38.5 mg/g) but lowest values for fat and ash while Citrullus vulgaris recorded the highest values of 35.3 and 3.4 mg/g There were no significant differences in values obtained for sodium, Cucumeropsis mannii had highest values for potassium and phosphorus (0.36 and 0.29 mg/kg). Citrullus vulgaris was outstanding in mineral content for magnesium with the highest value of 0.27 mg/kg and lowest for calcium (0.29 mg/kg) compared to 0.30 and 0.34 for Cucumeropsis mannii and Citrullus colocynthis respectively. Anti-nutrients were highest in Citrullus vulgaris and lowest in Cucumeropsis mannii. Acidic pH of 5.78 was recorded in Citrullus colocynthis but increased to 8.91 and 8.69 in Citrullus vulgaris and Cucumeropsis mannii indicating that Citrullus colocynthis may not be appropriate for ogiri production. Conclusion: Cucumeropsis mannii compares favourably with traditionally used Citrullus vulgaris resulting in higher fibre, protein, mineral contents with lower values of anti-nutrients and therefore recommended as a good substitute for ogiri production.

ABSTRACT

O coentro é a hortaliça mais utilizada como condimento na região de Mossoró-RN. Um experimento foi conduzido na Fazenda Experimental Rafael Fernandes da Universidade Federal Rural do Semi-Árido - UFERSA, no período de maio a junho de 2010, com o objetivo de avaliar o rendimento de coentro sob diferentes quantidades da planta trepadeira jitirana, incorporada ao solo como adubo verde. O delineamento experimental usado foi o de blocos completos casualizados com sete tratamentos e três repetições. Os tratamentos consistiram da incorporação de sete quantidades de jitirana (3,0; 6,0; 9,0; 12,0; 15,0; 18,0 e 21,0 t ha-1 de matéria seca de jitirana). A cultivar de coentro plantado foi a Verdão. As características avaliadas foram: altura e número de hastes por planta, rendimento e massa seca da parte aérea. O melhor desempenho agronômico do coentro foi observado na quantidade de 21,0 t ha-1 de jitirana. Para cada tonelada de jitirana incorporada ao solo observa-se um rendimento de coentro de 395 kg ha-1.


The ciliandro is the vegetable more used as seasoning in the area at Mossoró-RN. An experiment was conducted at the Experimental Farm Rafael Fernandes of the Universidade Federal Rural do Semi-Árido - UFERSA in the period from may to june 2010, with the objective of evaluating the coriander yield in under different amounts of plant clambering scarlet starglory, incorporated into the soil. The experimental design was randomized complete blocks with eight treatments and three replicates. The treatments were combinations of eight amounts of scarlet starglory (3.0; 6.0; 9.0; 12.0; 15.0; 18.0 and 21.0 t ha-1 dry matter). The coriander cultivar planted was Verdão. The characteristics evaluated in the coriander were: plant height and number of stalks per plant, yield and dry matter mass of shoots. The best agroconomic performance lettuce was observed in the amount of 21,0 t ha-1 scarlet starglory. For each fresh or dry scarlet starglory ton incorporated into the soil, it was observed a mean yield of coriander mass of 395 kg ha-1.
