ABSTRACT: One of the relevant economic importances of the “umbuzeiro” (Spondias tuberosa Arruda) to the northeastern semiarid region of Brazil is the fruit processing to obtaining preserves. However, there are limitations in the production and standardization of this product, such as color, taste and texture, which are problems in the quality, identity, making it harder to achieve new markets. This study was carried out aiming to evaluate the potential of “umbu” genotypes (Access 37, Access 44, BRS 48, BRS 52, BRS 55 and BRS 68) registered by Embrapa in the development of preserves. It was evaluated the product pH, total acidity, water activity, soluble solids, moisture, firmness, color (L*, a*, b*), reducing and non-reducing sugars, vitamin C, syneresis and consumer acceptance regarding the overall impression. The CATA method was applied to describe the sensorial profile of the samples. According to the results, it was observed a significant difference (p≤0.05) in the physico-chemical composition of the samples, being samples produced from the access 37 and BRS 68 more appropriated for processing of preserves (in bars), with greater firmness and less syneresis. Consumers indicated products from the genotypes 37, 44, BRS 52 and BRS 55 as the ones with highest acceptance regarding the overall impression; the consumers associated the samples in different characterizations, associating the access 37 and BRS 68 with the characteristics of firm and delicious; the commercial sample was characterized as acid, adstringent and terrible.

The “Pero de Cehegín” is an ancient local variety of apple grown in Murcia (Spain). In this study, microsatellites markers showed evidence of a unique profile that has never been reported before in other Spanish apple germplasm collections. Five “Pero de Cehegín” clones were evaluated and compared with two commercial apple varieties, “Fuji” and “Golden Delicious”, to assess its marketing potential. For this, the physical (weight, height, and width of the fruit, moisture content, firmness, and color of the fruit, among others), and chemical (total soluble solids, total acidity, and maturity index) properties of the fruits were evaluated. In addition, the content of bioactive compounds such as total polyphenol content, total antioxidant activity using the ABTS+, DPPH•, and FRAP methods, and the sugar profile were analyzed, and their sensory profile was also evaluated. Physico-chemical differences were found within the “Pero de Cehegín” clones and between the commercial varieties. “Pero de Cehegín” had a high firmness, high total soluble solids, very low total acidity, high FRAP antioxidant capacity, and more sucrose content in comparison with “Fuji” and “Golden Delicious”. These distinctive characteristics and the good appearance of the fruit make this variety a marketable product that will increase the offering of traditional, local, but underutilized fruit varieties.

The study aimed to develop a non-dairy-based probiotic-supplemented product using an underutilized crop in the Philippines such as the yellow passion fruit (Passiflora edulis f. flavicarpa Deg.). The physico-chemical properties (moisture content, water activity, pH, and total soluble solids), probiotics stability at different storage temperatures (4°C, 25°C, and 37°C), and the sensory characteristics of Lactobacillus plantarum S20-supplemented passion fruit juice powder was evaluated. Passion fruit juice powder and L. plantarum S20 were first prepared using low-temperature spray drying utilizing maltodextrin as a carrier, with yield as 42.97% and 21.17%, respectively. Spray drying of probiotics culture also resulted in 42.68% log survivability. The formulated juice powder had a final moisture content of 1.729±0.38% and water activity of 0.398±0.0051, and with recommended dilution with water, had a final pH and total soluble solids of 3.40±0.10 and 12.00±0.00° Brix, respectively. Results also showed that storage of the formulated juice powder at 4°C yielded the highest probiotic stability, maintaining a viable log count of 4.27 per g, while storage at 37°C showed no microbial growth. Sensory evaluation of probioticsupplemented passion fruit juice against a non-probiotic-supplemented one revealed significant difference in terms of color, sweetness, and sourness, while no significant difference was observed in terms of aroma, mouthfeel, and general acceptability.

AbstractSapota fruits are highly perishable and have short shelf life at the ambient conditions. The edible coatings have been used on different agricultural products in order to extend their post harvest life. In the present study, the polysaccharide based edible coating made up of sodium alginate and pectin (2%) was studied on the shelf life of sapota fruits. The coating of the fruits is done by dipping method with two dipping time (2 and 4 min). The both control and coated sapota fruits were stored at refrigerated temperature (4±1°C). The physico-chemical analysis including acidity, total soluble solids, ascorbic acid, pH, weight loss, colour and firmness were measured on 1, 8, 15, 23 and 30th day of storage. There was significant difference (p≤0.05) in these physico-chemical parameters between control and coated sapota fruits with 2 and 4 min dipping time. The sensory analysis of control and coated sapota fruits showed that, the polysaccharide coating with 2 minutes dipping time was effective in maintaining the organoleptic properties of the fruits.

Sapodilla has many uses from medicinal to dietary utilization. In recent years emphasis is focused on product diversification by development of value added sapodilla products to enhance its economic value. This study was carried out to investigate the effect of sugar concentration on the physiochemical properties like pH, moisture, ash, total acidity, viscosity, soluble solids, ascorbic acid and consumer acceptability of the product through sensory evaluation. Four samples S1, S2, S3 and S4 were formulated containing 550g, 600g, 650g and 700g sugar respectively. There was no significant difference observed in physiochemical properties of all sample due to sugar concentration. But among all samples S2 and S3 scored highest for color (7.7 and 7.9), flavor (7.6 and 7.7), taste (7.6 and 7.8), texture (7.2 and 7.9) and overall acceptance (7.5 and 7.7) which shows that jam with 550g and 600g sugar is best jam with good sensory attributes.

A salinidade provocada pelo mau uso da fertirrigação pode causar muitos danos às plantas e consequentemente à produção. Este trabalho teve como objetivo avaliar os frutos da cultura do pepino, em relação aos parâmetros pH, sólidos solúveis totais (%), acidez total titulável (g 100g-1 de amostra) e firmeza de polpa (kgf), cultivada em meio salino. Os tratamentos foram compostos pelos seguintes fatores: dois tipos de manejo de fertirrigação (M1 e M2) e seis níveis iniciais de salinidade do solo (S1=1,5; S2=2,5; S3=3,5; S4=4,5; S5=5,5 e S6=6,5 dS m-1). O experimento foi conduzido na área experimental do Departamento de Engenharia Rural da ESALQ/USP, Piracicaba/SP. O plantio foi realizado em vasos, utilizando solo arenoso e irrigação por gotejamento. A salinização foi obtida com soluções oriundas dos próprios fertilizantes. Como principais resultados, tem-se que o tipo de manejo da fertirrigação adotado interfere menos que os níveis de salinidade do solo em relação às características físico-químicas dos frutos, porém houve diferença significativa para o parâmetro acidez total titulável em seus valores médios tanto no tipo de manejo de fertirrigação adotado, como nos níveis de salinidade do solo.   UNITERMOS: fertilizantes químicos, condutividade elétrica, Cucumis sativus L.     MEDEIROS, P.

The objective of this study was to evaluate the cucumber fruits in relation to parameter Ph, total soluble solids (%), total acidity (g 100g-1 sample), and pulp firmness (kgf) cultivated in saline environment. The treatments were: two fertigation management types (M1 and M2) and six initial levels of soil salinity (S1=1.5; S2=2.5; S3=3.5; S4=4.5; S5=5.5 and S6=6.5 dS m-1). The experiment was conducted at the Rural Engineering Department of ESALQ/USP in Piracicaba/SP, Brazil experimental area. The grove was planted in pots using sandy soil and drip irrigation. The salinity was obtained with solutions derived from the actual fertilizer. The main results showed that the type of fertigation management adopted interfered less than the soil salinity levels regarding the fruits physicochemical characteristics; however, there was a significant difference for the parameter total acidity mean values in the fertigation type adopted as well as in the soil salinity levels.   KEYWORDS: chemical fertilizers, electric conductivity, Cucumis sativus L.

An antibacterial treatment consisting of 1.5% lactic acid plus 1.5% hydrogen peroxide at 40°C for 15 min was effective in reducing foodborne bacterial pathogens on raw apples. However, the effects of this treatment on an apple's sensory characteristics and the extent of consumers' willingness to use the treatment at home were not known. This study was undertaken to determine the sensory acceptability and chemical characteristics (pH, soluble solids, and total acidity) of apples subjected to the sanitizing treatment and to obtain information on consumers' purchase behavior, apple handling and consumption practices, and willingness to use an antibacterial treatment. Untrained consumers (n = 80) evaluated the appearance, color, aroma, flavor, texture, and overall appeal of untreated (control) and treated Red Delicious apples that had been stored at 5°C for 0, 6, and 10 days. Panelists used a nine-point hedonic scale (1 = “dislike extremely”; 5 = “neither like nor dislike”; 9 = “like extremely”) to evaluate sensory acceptability. Treatment and storage had no significant effect on the appearance, color, or aroma of the samples. Flavor ratings ranged from 6.2 (“like slightly”) to 7.0 (“like moderately”). There was no significant difference among any of the control and treated apples stored for 0 days or among those stored for 6 days. Although apples stored for 10 days received the lowest ratings (6.2 to 6.3), they still had an acceptable flavor (6, “like slightly”), and panelists could not perceive differences between the control samples and the treated samples on day 10. The same trends were noted in texture ratings and in overall liking ratings. Treatment and storage had a minimal effect on pH (range, 3.96 to 4.02), soluble solids (range, 11.8 to 12.9° Brix), and total acidity (range, 0.20 to 0.23% malic acid), which are important for apple flavor. Many consumers (87%) were concerned about fruit safety, and 53.2% were willing to try an antibacterial treatment at home. However, 74% would not be willing to use it if a 15-min heating-and-soaking step were required. Implementation of the treatment may be more feasible in the packinghouse than in the home.

<p>Tomato purees were produced from <em>De Rica </em>and<em> Roma</em> cultivars of tomato, packaged in high density polyethylene and stored at ambient temperature (32±2 ºC). The stored purees were analysed weekly for physicochemical composition, sensory attributes and microbial load until they became unwholesome. There was a significant (p&lt;0.05) falling in Titratable Acidity (TTA) within the first five and six weeks for <em>De Rica</em> and <em>Roma</em> purees respectively. TTA values dropped from 12.43 to 8.40 and 10.69-7.43 for <em>De Rica</em> and <em>Roma</em> purees respectively. Total solid (TS) of the purees decreased significantly (p&lt;0.05) from 16.2% to 9.08% for <em>De Rica</em> puree and 17.89% to 9.99% for <em>Roma</em> puree within the first four weeks of storage and became stable at the later weeks of storage. <em>Roma</em> puree had higher TS throughout the storage period. Total Insoluble Solid of the purees increased significantly from 3.07% and 4.01% for <em>De</em><em> </em><em>Rica</em> puree and 2.3% and 3.44% for <em>Roma</em> puree within the first week of storage. The values however, decreased significantly is (p&lt;0.05) at the second week of storage from 4.01% to 1.19% for <em>De Rica</em> puree and 3.44% to 1.89% for <em>Roma</em> puree. The bulk density of the samples decreased significantly (p&lt;0.05) from 1.14g/ml to 0.95 g/ml for <em>De Rica</em> puree and 1.12 g/ml to 0.95 g/ml for <em>Roma</em> puree through the storage period. There was an insignificant (p&gt;0.05) increase in total bacteria count from 140 CFU/g to 320 CFU/g for <em>De Rica</em> puree and 126 CFU/g to 280 CFU/g for <em>Roma</em> puree within the first two weeks of storage. The values increased significantly (p&lt;0.05) from 640 CFU/g to 137,000 CFU/g for <em>De Rica</em> puree and 590 CFU/g to 122,000 for <em>Roma</em> puree from the third to the tenth week of storage. There was no significant difference (p&gt;0.05) between the freshly produced <em>De Rica</em> puree, <em>Roma</em> puree and the commercial sample in appearance, colour, taste and overall acceptability before and during storage. Marked rejection of the purees was observed at the eight week of storage.</p>
