Avaliação Das Perdas De Frutas E Hortaliças No Mercado Varejista De Mineiros-Go: Um Estudo De Caso

Abstract

RESUMOO presente trabalho teve como objetivo realizar levantamento das principais perdas de frutas e hortaliças frescas no mercado varejista do município de Mineiros-GO, bem como dos fatores que as provocam. O trabalho de pesquisa foi executado mediante visitação aos equipamentos varejistas (supermercados, quitandas/sacolões e feira-livre) para aplicação de questionário no período de dezembro de 2005 a janeiro de 2006. Os resultados indicaram que foram perdidos 2,9% do volume total de frutas e hortaliças comercializado semanalmente. Os supermercados e as quitandas obtiveram as menores porcentagens de perdas (2,1 e 4,0%, respectivamente), porém a feira-livre apresentou elevada porcentagem de perda (15,9%). O pêssego (50,0%), ameixa (14,7%), abobrinha (9,0%), mamão (7,2%), nectarina (7,1%), tomate (6,2%), abacaxi (6,0%) e banana (5,2%) obtiveram médias a altas porcentagens de perdas em relação ao volume comercializado pelo varejo. A rede varejista considerou que o armazenamento inadequado é a principal causa das perdas dos produtos hortifrutícolas. Embora o mercado varejista de Mineiros demonstre baixos níveis de perda de frutas e hortaliças, este é passível de estruturação e adequações para redução das perdas.Palavras-chave: perdas no varejo; frutas; hortaliças; comercialização. ABSTRACTThe objective of this work was to evaluate losses of fruits and vegetables on the market of the Mineiros city (Goiás State, Brazil), as well as its causes. The research was done at different retail equipments (supermarkets, groceries stores and street market) by questionnaire application from December 2005 to January 2006. The results showed week total losses of 2.9% for fruits and vegetables. Supermarkets and groceries stores losses (2.1% and 4.0%, respectively) were lower than the street market ones (15.9%). Peach (50.0%), plum (14.7%), summer squash (9.0%), papaya fruit (7.2%), nectarine (7.1%), tomato (6.2%), pineapple (6.0%) and banana (5.2%) showed medium to high rates of losses over the total volume commercialized at the different markets. The results showed that inadequate storage are the main causes of fruit and vegetable losses in the Mineiros retail trade. Although there are low losses of fruit and vegetables on the Mineiros market improvement could be done to adequate handling system and postharvest facilities to reduce that losses.

Origin and post-harvest losses of vegetables in the microregion of Chapadinha, Maranhão, Brazil

“…According to Tofanelli et al (2009a), physiological losses can be reduced not only by the adoption of appropriate storage techniques, such as refrigeration and/or modified atmosphere, but principally by adequate planning of the quantity of fruits offered, taking into account the seasonal market variations in demand during and between months.…”

“…As noted by Calbo (2006), this serves as the "gateway" to microorganisms, such as bacteria, which are the major causes of potato rot. Tofanelli et al (2009a), as perdas fisiológicas podem ser reduzidas não apenas pela adoção de técnicas de armazenamento, como a refrigeração e/ou atmosfera modificada, mas, principalmente, pelo adequado planejamento da quantidade ofertada, com atenção às diretrizes de sazonalidade de mercado, ao decorrer de cada mês.…”

Postharvest losses of fruits and vegetables in different microregions of Maranhão, Brazil

“…The following decreasing order of losses was obtained: papaya (17.90%) > avocado (16.55%) > guava (13.82%) > grape (9.80%) > passion fruit (8.90%) > mango (7.80%) > banana (7.60%) > watermelon (5.20%) > pineapple (5.08%) > apple (5.00%) > melon (4.20%). Among the relative losses of climacteric fruits, the values obtained for papaya (17.90%), avocado (16.55%), and guava (13.82%), according to the classification proposed by Tofanelli et al (2009), were classified as high losses. However, these fruits are not included among the greatest volumes offered, probably because they have certain morpho-physiological traits, such as high-water content, high respiratory rate, and also thin epidermis.…”

“…VV represents the mean quantity of fruit and vegetables sold per week (kg week -1 ). These relative losses were classified as low (less than or equal to 5%), medium (between 5.1 and 10.0%), and high (greater than or equal to 10.01%), as proposed by Tofanelli et al (2009). Estimates of relative losses of all fruits and vegetables marketed allowed to estimate total losses, in kilograms, on the volume offered per week.…”

Environmental accounting: an analysis on the transformation of environmental impacts in sustainable and socioeconomic improvement, in the Supply Center Hortifrutigranjeiro – Ceasa MA

“…In this linkage, a differentiated model was generated through this understanding, which consisted of three public front: the Brazilian food company (COBAL), Brazilian storage company (CIBRAZEM), and the production financing company (CFP). In the organizational process, these types of programs allowed for greater proximity to European models, because they established several commercial cultural projects in the same space, rather than just food, and the process followed the mixed (public and private) model of fiscal management (TOFANELLI et al, 2009). From these advances it was possible to conceive of the elements required, to create a fundamental bases for the creation of the CEASA, from which measures and improvements; could be generated from a central perspective; these mainly consisted a union between the public and the private sector.…”
