The role of local seasonal foods in enhancing sustainable food consumption: a systematic literature review

This article aims to review the current literature pertaining to the effects of eating local seasonal food on sustainable consumption. To this end, we examined definitions of seasonal and local food, the methodological approaches adopted to study the impact of seasonal consumption on sustainability, and sustainability dimensions investigated in journal articles. Highlighting what seasonal and local means, it is crucial to evaluate the effect of the consumption of these foods on sustainability. A systematic review of the literature was conducted using Scopus and Clarivate’s Web of Science database in line with the recommendations from the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Our findings suggest that the concept of local seasonality provides relevant information to the study of sustainable consumption. However, for better use of this concept, it is crucial to define what is local. At this point, regulation of labels based on geographic proximity or political boundaries proves pertinent.info:eu-repo/semantics/publishedVersio

Food Processing Innovation: A Case Study with Pressurized Passion Fruit Juice

Tropical fruit juice production shows an annual increase in volume of 15 to 20% in Brazil. Growing demand for processed fruit pulp arouses juice industry interest to search for novel technologies. High Hydrostatic Pressure (HHP) is an innovative technology which allows juice production with improved sensory characteristics compared to pasteurization, meeting consumer demands for fresh-like foods. Despite recognized advantages of pressurized products described in the literature, a positive consumer attitude towards them is required to guarantee their success in today’s competitive global market. The objective of this study was to evaluate the effect of packaging attributes on consumer expected liking and purchase intention of passion fruit juice. One hundred and twenty consumers evaluated twelve prototypes for expected liking and purchase intention. Data were analyzed using ANOVA, Conjoint and Cluster Analyses. Results showed that information about benefits of used technology (HHP) presented on the package played an important role on consumer attitude, suggesting a positive contribution to his/her satisfaction, a key point for the food industry.Tropical fruit juice production shows an annual increase in volume of 15 to 20% in Brazil.

O objetivo deste trabalho foi avaliar os efeitos das condições de extração no rendimento e qualidade do leite de castanhado- Brasil despeliculada. O processo básico para elaboração do referido leite incluiu as etapas de despeliculação das amêndoas das castanhas, desintegração das castanhas despeliculadas e centrifugação do produto. Na etapa de desintegração foram estudadas 4 temperaturas (25, 50, 75 e 100 ºC) com uma ou duas extrações. As amostras experimentais obtidas foram avaliadas quanto à composição, rendimento em extração e avaliação sensorial de doçura. Os leites de castanha obtidos a 75 ºC com 1 e 2 extrações apresentaram rendimento em sólidos, proteínas e óleo significativamente (p = 0,05) superiores aos demais. O leite de castanha elaborado a 75 ºC com uma extração, considerado o melhor sob o ponto de vista tecnológico, foi formulado com diferentes concentrações de açúcar (2, 3 e 4%) e submetido ao teste de preferência. O leite de castanha, com 3% de açúcar foi preferido por 78% dos consumidores que avaliaram o produto. EFFECT OF EXTRACTION CONDITIONS IN YIELD AND QUALITY OF SKINNED BRAZILIAN NUTS MILK Abstract The objective of the present work was to evaluate the extraction conditions in yield and quality of skinned brazilian nuts milk. The basic process for the elaboration of such milk included the stages of skinning the brazilian nuts, desintegration of the skinned nuts and centrifugation of the product. In the stage of desintegration 4 temperatures were studied (25, 50, 75, and 100 ºC) with one or two extractions. The experimental samples obtained were evaluated for composition, extraction yield and sensorial evaluation of sweetness. The nut milks obtained at 75 ºC with 1 or 2 extractions presented solid yield, proteins and oil significantly superior to the others. The nut milk elaborated at 75ºC with one extraction considered the best in the technological point of view, was formulated with different concentrations of sugar (2, 3 e 4%) and submitted to preference test. The nut milk with 3% of sugar was prefered by 78% of consumers that evaluated the product

A study to guide breeding of new cultivars of organic cherry tomato following a consumer-driven approach

AbstractAgricultural studies focusing on the development and/or improvement of new varieties of fruits and vegetables usually prioritize the productivity, disease resistance, response to fertilization, and higher nutrient content. However, new product development needs to take into account not only flavour preference, but also consumer preference for appearance since without tasting products, consumers have to make decisions based on the way a product looks. The present study evaluated the sensory characteristics and consumer preference of ten promising accessions of organic cherry tomato for fresh consumption aiming at identifying the sensory attributes related to appearance that contributed to consumer liking/disliking the fruit. More specifically, the objective of the study was to guide producers regarding the target appearance attributes that play a role on consumer acceptance of cherry tomatoes. Ten accessions of organic cherry tomatoes were evaluated by a trained panel using the QDA methodology, and also by 80 tomato consumers for the acceptance of appearance and intention to purchase. The results achieved after integrating these two data sets (from the trained panel and consumers) in a multidimensional map allowed the elucidation of consumer liking of tomatoes in relation to the appearance, i.e. drivers of liking/disliking were identified. Results revealed that tomatoes with round shape and red colour (reddish) (cultivar ENAS 1031, ENAS 1010, ‘Perinha Agua Branca’, Super Sweet, and ‘Joana’) were the most liked cherry tomatoes. Those genotypes were also liked by the smallest segment (17.5% of participants) but for them unusual shapes (oblong and pear), orange-yellow colour, and bigger size were also liked. Despite the small number of participants in this study (80 consumers), new shapes and colours for the organic cherry tomatoes could be considered promising alternatives in the Brazilian market, and can be an opportunity for the producers of the state of Rio de Janeiro

CINÉTICA DA DEGRADAÇÃO DA TEXTURA DE PIMENTAS EM CONSERVA

O objetivo deste trabalho foi avaliar o efeito do tratamento térmico (pasteurização) na cinética de degradação da textura de pimentas em conservas. Três cultivares de pimentas (CNPH 0053 – Pimenta Dedo-de-Moça, CNPH 0279 – Pimenta Escabeche e CNPH 0280 – Pimenta de Cheiro), produzidas pela Embrapa Hortaliças (em Brasília), foram avaliadas. As pimentas foram branqueadas por imersão em salmoura (2% NaCl) a 100ºC durante 1 minuto. Em seguida, foram envasadas em vidros e pasteurizadas a 100ºC por 10, 20, 30 e 40 min, utilizando-se como líquido de cobertura salmoura acidificada com ácido acético (2% NaCl). As amostras processadas foram analisadas quanto à firmeza e avaliadas quanto ao modelo cinético de degradação da textura. Os resultados revelaram que a textura dessas pimentas seguiu reação de 1ª ordem nos tempos de processamento da pasteurização analisados e o tempo de redução decimal (D) para as três pimentas em conserva encontrou-se abaixo de 100 minutos

Bananas apresentadas em dedos e buquês: qualidade e preferência do consumidor

No Brasil é comum a comercialização de bananas em penca, contribuindo com as perdas pós-colheita. No entanto, buquês reduzidos e dedos individuais podem ser alternativos, desde que a qualidade e a aceitação pelo consumidor não sejam comprometidas. Objetivou-se avaliar a influência da forma de apresentação (dedos e buquês) e do genótipo de banana (BRS Princesa e Grande Naine) na qualidade dos frutos e na preferência do consumidor. A qualidade de bananas Grande Naine e BRS Princesa foi avaliada durante dez dias após a colheita (dac). As três formas de apresentação, no ponto de colheita, dedos, buquê de três (b3) ou seis frutos (b6) e a aparência dos genótipos apresentados em penca, foram avaliadas por 110 consumidores de banana em relação à aceitação e à intenção de compra. Bananas BRS Princesa e Grande Naine apresentadas em b6 tiveram menor atividade respiratória a partir do sexto e do quarto dia após a colheita, respectivamente. A mesma apresentação proporcionou menor perda de massa fresca para BRS Princesa, e Grande Naine aumentou independente da forma de apresentação. Os consumidores gostaram da aparência de bananas Grande Naine e BRS Princesa em penca, indicando que comprariam tais frutos. Para os frutos pequenos, como de BRS Princesa os consumidores declararam maior intenção de compra para as formas b3 e b6. Entretanto, os consumidores comprariam bananas maiores, como são as Grande Naine, independente da forma de apresentação. A qualidade e os aspectos sensoriais são distintos em função da forma de apresentação da banana Grande Naine e BRS Princesa.Palavras-chave: Análise sensorial. Formas de apresentação. Musa sp.
