Estudo das características sensoriais e da composição química de queijo de coalho industrializado / Sensorial characteristics and chemical composition of manufactured coalho cheese

O trabalho teve como objetivo avaliar as características de queijo de coalho industrializado utilizando a Análise Descritiva Quantitativa (ADQ), teste de aceitabilidade, intenção de compra e análises físico-químicas. O teste de aceitabilidade foi realizado por 50 consumidores. A amostra A foi analisada nos aspectos como: aroma típico de queijo de coalho e sabor típico de queijo de coalho; a amostra B foi caracterizada pela coloração amarela e qualidade de mastigação. Os atributos, como olhaduras, sabor de gordura e sabor ácido não foram relevantes na caracterização das amostras analisadas. A amostra C recebeu maior pontuação nos atributos como aroma de manteiga (5,4) e sabor salgado (4,6). A amostra A obteve a maior média de aceitabilidade para aparência (7,14) e sabor (7,02) e, consequentemente, a maior intenção de compra nos conceitos “certamente compraria” (40,0%) e “provavelmente compraria” (32,0%). As amostras apresentaram alto teor de umidade, variando de 51,98% (amostra A) – 53,25% (amostra C). A amostra A apresentou teor de cloreto de 1,37%, acidez de 0,91 (g% de ácido láctico) e pH 6,0. O teor de sal e a porcentagem de acidez encontrados na amostra A estão próximos aos valores desejáveis para queijo de coalho.

This study evaluated the defining features of manufactured coalho cheese by Quantitative Descriptive Analysis (QDA), as acceptability test, purchasing intention and physical-chemical analyses. The acceptability test was carried out by 50 consumers. The sample A was assessed on the features as typical curd cheese aroma, typical curd cheese taste, while sample B was evaluated on its yellow color and chewiness. Characteristics as holes, fatty taste, and acid taste were not relevant for qualifying any of the samples. Sample C was highly scored on buttery aroma (5.4) and salty taste (4.6). Sample A received the highest acceptance score on appearance (7.14) and taste (7.02) features, and therefore it got the highest purchasing intention score, being “I would certainly buy” (40.0%) and “I would probably buy” (32.0%). The samples showed a highhumidity varying from 51.98% (sample A) to 53.25% (sample C). Chloride contents in sample A was 1.37%, and acidity of 0.91 (g% of lactic acid) and pH 6.0. Presumably, the salt contents and the percentage of acid found in sample A are close to the desirable rates for coalho cheese.

Consumers' Purchasing Intentions of Organic Foods in relation to the Perceived Health Concerns, Healthy Eating Practices and Attitudes, and Food Choice Motives / 대한지역사회영양학회지

This study investigated the correlations of five constructs - health concerns, healthy eating practices and attitudes, food choice motives, attitudes toward organic foods - in the formation of behavioral to the purchasing intentions of organic foods. An instrument encompassing health perception, attitudes, habits and personal traits was developed through the comprehensive reviews of the literature and the assured validity and internal reliability of the contents. The questionnaire was administered to the students of three universities at Daegu, Kyungpook province. A total of 288 questionnaires were collected for a response rate of 96.0%. The correlations of five constructs and purchasing intention were tested simultaneously using structural equation modeling. Healthy eating practices and attitudes toward organic foods were found to be the determinants which directly influence the intention to purchase organic foods. Health concerns didn't show direct relation to the purchasing intention of organic foods. The hypothesized path from the health concerns to the purchasing intentions was not supported. The results indicated that food choice motives and healthy eating attitudes should be managed to achieve higher behavioral intention to purchase organic foods.
