title: Consumer perception of Petit-Suisse cheese: identifying market opportunities for the Brazilian dairy industry

description: Abstract The dairy market is hugely competitive, with dairy industries always looking for new products to reach the consumer. Projective techniques, such as the Completion task, are great allies in this process, as they identify consumer needs and expectations, which helps in developing brand new, more competitive products. Petit-Suisse cheese is a product which is well established in the Brazilian dairy market; however, its consumption is restricted to children and has few sales variations. The objective of the present work was to investigate the consumers’ perception about Petit-Suisse and to identify possibilities of market expansion for this product category, through the technique of Completion task. According to the participants, Petit-Suisse is a widely accepted product, and its recognition was strongly related to the brand. Besides, although considered a product intended primarily for children, as a snack option, there is a substantial market possibility for the consumption of this product by other groups. Completion task made it possible to identify that there are different aspects of Petit-Suisse cheese, like flavor, composition and functional appeal that can still be explored by the dairy industry in making more competitive products on the market.

title: Effect of processing, storage and type of glass packaging on the quality of jelly produced from a Brazilian Cerrado fruit

description: Abstract The objective of this study was to prepare a jelly with the pulp of curriola as raw material and evaluate the effect of processing, type of glass packaging (transparent and amber) and storage time on the quality of the jelly by means of physical (color), chemical (proximal composition, total soluble solids, titratable acidity and pH), microbiological (coliforms at 35 °C and 45 °C, filamentous fungi and Salmonella sp.) and sensorial analyses (sensory acceptance and purchase intent). For this, the raw material and the freshly prepared jelly were compared and a completely randomized design in factorial 2 x 5 was used. There were two levels of light exposure (transparent packaging and amber packaging) and five storage times (0, 3, 6, 9 and 12 months), with four replicates. Processing affected all physical, chemical and microbiological characteristics of the freshly prepared jelly. Between the two factors studied, only the storage time significantly influenced the jelly quality, except protein, ash, dietary fiber content and taste and purchase intention. According to the microbiological analysis, the product is within the legislated recommendations. It was well accepted sensorially and can be kept under ambient conditions and still maintain its durability for up to twelve months.

title: The effect of extraction method and types of coagulants on the results and physicochemical properties of tofu

description: Abstract Extraction and coagulation techniques are essential stages in tofu production. This research studies the effect of extraction and coagulation techniques on physicochemical properties of soybean extract, soy pulp, and tofu. This study applies three extraction techniques, namely manual heat extraction, manual cold extraction, and cold extraction using mechanical devices. They used nigari coagulant. As a control, the process of making tofu follows the procedure process as in the small industry of tofu with whey coagulant. The measurement of material mass balance is done at each stage of the process, while the evaluation of the product includes water content, ash, protein, fat, magnesium, and texture. The experimental results show that an increase in the ratio of water to soybeans and the increase of extraction temperature can increase the amount of extracted protein. The coagulation using nigari produced 22.18 kg tofu in hot extraction treatment, 19.61 kg in cold extraction and 17.60 kg in machine extraction. The control treatment produced 36.8 kg of tofu. The water content in the control treatment was higher than the other three treatments. Protein levels, magnesium levels, hardness and chewing power for treatment with nigari coagulant were significantly higher than those with whey.

title: Physicochemical characterization, carotenoid content and protein digestibility of pumpkin access flours for food application

description: Abstract Pumpkin (Cucurbita maxima) research has been growing because of its characteristics, such as the attractive color, low-cost production, nutritional potential, and functional properties for food application. In this context, pumpkin processing for flour production provides a full possibility for the consumption of this vegetable, being thus an alternative for the agribusiness. Research institutes are developing new genotypes for multiple applications of this vegetable. The objective of this study was to characterize pumpkin flours from four access and evaluate its physicochemical characteristics, carotenoid content, and protein digestibility. The dried pumpkins were ground in a knife mill and stored in a glass bottle at room temperature and protected from light. The pumpkin flours presented different proximal composition. All flours presented low water activity, which is microbiologically safe for storage. As for the absorption index and water solubility, both presented high values compared to the values of other flours found in the literature. The flours presented colorimetric profile from yellow to orange, and are rich sources of carotenoids and fibers. The four samples presented high values of protein digestibility, desired for food application. The results indicate that the four pumpkin access flours are indicated for application in foods.

title: Lutein as a functional ingredient in sheep milk yogurt: development, characterization and extraction recovery

description: Abstract The research aimed to evaluate the behavior of different concentrations of lutein added in sheep milk yogurt. The work verified the effect on acidity, pH, color, lutein degradation, and recovery during storage. Different added lutein concentration into yogurt were compared: 0.00 mg; 3.0 mg; 3.45 mg; and 3.9 mg (·100 mL-1). Analyzes were performed on days 1st, 15th, 30th, and 45th of refrigerated storage (5 °C). Lutein did not influence fermentation patters, but post acidification was observed, mainly in groups with the highest lutein concentrations. The amount of lutein recovered was different between groups (P &lt; 0.05) due to treatment. Some differences (P &lt; 0.05) in the same treatment occurred over time, tending to decrease lutein recovery. For all treatments, up to the end of storage, the final amount of lutein characterized the product as a nutritional source of this element. However, lutein recovery in G4 has reached the minimum daily intake recommended by researchers for health benefits. Recovery ranged from 81.9 ± 0.76·100-1 (w·w-1) to 76.31 ± 1.07·100-1 (w·w-1) on the storage period. L* has no difference (P &gt; 0.05) between groups with different added lutein concentrations. In contrast, a*, b*, c*, and YI (yellowness index) were different (P &lt; 0.05).

title: Improving composition and microbiological characteristics of milk kefir using colostrum

description: Abstract Kefir characteristics are influenced by raw materials. Fresh milk and colostrum have different characteristics. In this research, colostrum was used as additional material in kefir production which could affect the chemical, microbiological, and antimicrobial properties of final the product. This study was aimed to investigate the chemical and microbiology properties of kefir prepared from milk, colostrum and milk-colostrum mixes. Kefir was prepared by adding kefir grains to 100% fresh milk, milk-colostrum mixes (20:80%; 40:60%; 60:40%; 80:20%) and 100% colostrum. Fermentation was allowed under room temperature for 24 hours. Results showed that all treatments produced kefir with relatively similar titrable acidity, free fatty acids, and fat contents. The highest levels of ethanol, total solids and protein content were observed in kefir produced from 100% colostrum. The average total microbes were 6.37 – 7.51 log CFU/ml; 7.04-8.23 log CFU/ml bacteria; 6.92-7.48 log CFU/ml LAB and 5.54-6.55 log CFU/ml yeast. Water activity values ranged from 0.85 to 0.89. The highest microbial and antimicrobial properties were shown by kefir produced from milk-colostrum mix of 20:80%.

title: Study on the sensory acceptance and check all that apply of mixed juices in distinct Brazilian regions

description: Abstract Fruit juices are on the rise, due to the search new mixes, flavors and nutritional value. This research investigated the acceptance and sensory profile of mixed juices. Sixteen (16) mixed juices with caja, umbu, cocoa and mango flavors were studied, using acceptance and check-all-that-apply (CATA) tests in different cities (n = 226). Juices A1 and D1 had the highest scores in Porto Alegre-RS, Brazil (respectively, 7.15 and 6.91). Differently from Salvador-BA, Brazil, where the highest scores were D2 (6.76) and D3 (6.71). Using CATA, it was shown that customers in the Southern Region characterized samples differently from customers in the Northeastern Region, and the correspondence analysis, showed that consumers in Porto Alegre-RS presented different attributes than those in Salvador-BA, with respect to mixed juices and their acceptance. It is suggested the validity of the consumer data in the characterization of the sensory parameters of the mixed juices and that the familiarity with the fruit flavors interfered in the acceptance of the same.

title: Analysis of the chemical properties of salted cobia (Rachycentron canadum)

description: Abstract Aquaculture of cobia (Rachycentron canadum) is still incipient in Brazil, as well as the sale of its meat. However, there is a market demand for this product in the state of Rio de Janeiro. The salting process for the meat of cultivated cobia is a way of preserving and marketing the product for the growers. Thus, the present study aimed to assess the chemical properties of salted cobia meat. Market-sized cobia grown in net-tanks located in Baía de Ilha Grande, Angra dos Reis, Rio de Janeiro, Brazil were used. The fish were eviscerated (gutted), beheaded and lightly flattened. The fillets “charutos” were then subjected to brine salting for 6 days, immersed in saturated brine at refrigeration temperature. After the preparation of the product, analyzes of percent composition, chloride content and lipid profile were performed. The product had high concentrations of protein (20.16%), lipids (19.88%) and 6.56% of total chloride. Lipid profile assessment showed significant percentages of palmitic (6.66%) and oleic (4.99%) acids. Therefore, it is concluded that the salted meat of cobia has good nutritional quality, and the product is a source of palmitic and oleic acids that help preventing cardiovascular diseases and lowering cholesterol levels.
