The production of fruits and vegetables is listed as one of the most relevant activities in brazilian agricultural conjuncture. However, the amount of losses occurring along the production chain is alarming, especially in the postharvest stage. Thus, it was aimed to conduct a survey of postharvest losses and characterize the scenario of commercialization of fresh produce in the retail market of seven cities in the east of Maranhã o state. This work was carried out through direct interviews with 145 traders. The questionnaire with objective questions that covered socioeconomic aspects, handling, flow, conditioning, storage, marketing, and postharvest losses was applied to them. It was found that the traders had little schooling (92% of traders do not have a high school level) and lack adequate technical knowledge of produce, management, and marketing of fruit and vegetable produce. The traded vegetables are sourced from Piauí , Bahia and Ceará , and drained through canvas-covered trucks (86%). The three vegetables with the highest loss estimates are bell pepper (16.42 ± 2.21%), lettuce (11.79 ± 0.42) and tomato (11.38 ± 0.19%). Though, for fruits, it highlights plum (35.65 ± 1.34%), papaya (17.93 ± 3.79%) and guava (15.63±2.79%). 337 Among the causes, those of physiological order was the most impacting. The largest losses of vegetables occurred in Coelho Neto (17.78%), Timon (13.46%) and Brejo (10.73%) cities. Regarding fruits, the order was Coelho Neto (11.48%), Brejo (11.27%) and Timon (10.84%). There is a need for better training and awareness of traders regarding the adoption of good post-harvest practices and proper management of the commercial activity, as a way to increase the profitability of this activity, which on average is equivalent to two minimum wages per month.
O girassol (Helianthus annuus L.) é uma oleaginosa que se caracteriza por sua adaptabilidade às diferentes condições edafoclimáticas e sua versatilidade, com aproveitamento ornamental, na alimentação animal, produção de óleo para consumo humano e produção de biodiesel. Dentre os substratos alternativos, a palha de arroz carbonizada (PAC) vem sendo intensamente utilizada nos últimos anos para produção de mudas, outra matéria-prima com potencial para composição de substratos é o caule decomposto da palmeira de babaçu (CDB). Objetivou-se avaliar diferentes proporções de caule decomposto de babaçu e palha de arroz no desenvolvimento do girassol. O experimento foi realizado em casa de vegetação no Centro de Ciências Agrárias e Ambientais da Universidade Federal do Maranhão (UFMA), no município de Chapadinha-MA. Adotou-se o delineamento experimental inteiramente casualizado, com seis tratamentos (T) e quatro repetições. Os tratamentos consistiram em diferentes formulações de substrato com 0%, 20%, 40%, 60%, 80% e 100% de PAC acrescidos de CDB. Foram quantificadas as seguintes variáveis: emergência de plântulas; número de folhas; altura de planta; diâmetro do caule; comprimento do sistema radicular; volume radicular; massa seca do sistema radicular; massa seca da parte aérea; massa fresca do sistema radicular; massa fresca da parte aérea e estabilidade do torrão. Os dados foram submetidos à análise de variância pelo teste “F”, e os T comparados entre si pelo teste Tukey a 5% de probabilidade através do programa computacional Assistat®. Conclui-se que o T1 com 100% de PAC acrescido de 0% de CDB exerce influência positiva no desenvolvimento de plantas de girassol ornamental.
O pimentão (Capsicum annum L.) é uma hortaliça altamente perecível, o que reduz a sua vida pós-colheita, caso não seja conservada adequadamente. Objetivou analisar a eficiência de diferentes revestimentos plásticos sobre a conservação pós-colheita do pimentão verde. Os pimentões foram adquiridos na CEASA de São Luís (MA) e encaminhados ao laboratório. O delineamento utilizado foi o inteiramente casualizado, em parcela subdividida no tempo (3, 6, 9 e 12 dias de armazenamento), com três tratamentos (sem embalagem, filme plástico e saco hermético), quatro repetições e dois frutos por parcela (bandeja). Os pimentões foram armazenados sobre bancada, em condição ambiente (T = ± 25°C; UR = 48%), durante 12 dias. Avaliaram-se a perda de massa fresca, acidez total titulável (ATT), pH e sólidos solúveis totais, bem como suas correlações no amadurecimento do pimentão. Ao término do estudo, recomenda-se o uso de saco hermético na conservação pós-colheita de pimentão verde, pois esta tecnologia propicia conservação de importantes atributos de qualidade, como a massa fresca, acidez, pH e sólidos solúveis, durante 12 dias de armazenamento ambiente. Isso pode reduzir perdas quantitativas e/ou qualitativas, com reflexos positivos nos indicadores socioeconômicos e ambientais da comercialização de pimentão verde.
Several studies have highlighted the variations in consumption habits, compared to the perspectives on food, social class and lifestyles of society. Among the different food groups, underground vegetables are of great importance in human nutrition as one of the main energy sources available for food. Among them, the yam stands out for its high nutritional and energetic power. In this way, the aim was to define the frequency, consumption profile and yam preference, ‘Chinese’ and ‘São Tome’ varieties. For this, a questionnaire of socioeconomic nature, feeding frequency and sensorial evaluation was applied to 52 students of a public university. At the end of the study, it was found that 71% of the students knew the yam, but only 50% had ever consumed the vegetable. It was observed that 85% of the interviewees never or hardly ever consume the tuber, 29% do not know the vegetable and 50% never consumed. Regarding consumption reasons, 25% of the respondents chose the taste as the main reason to consume yam and only 3% consume by the appearance of the product. The interviewees had food frequency in relation to the yam, linked to the palatability of the vegetable (25%) and of the two varieties analyzed, 69% of the interviewees prefer to consume the ‘São Tome’ yam. Given the importance of food in this vegetable, it is important to stimulate consumption, especially among younger individuals, with ages ranging from 20 to 25 years.
