Chemical, physico-chemical and sensory characterization of mixed acai (Euterpe oleracea) and cocoa's honey (Theobroma cacao) jellies/Caracterizacao quimica, fisico-quimica e sensorial de geleias mistas de acai (Euterpe oleracea) e mel de cacau (Theobroma cacao)(adequar o resumo de acordo com o abstract).

INTRODUCTION

Cocoa and acai are fruit produced in the humid tropics and have considerable importance and use in the market. Their excellent nutritional value and high energetic value were conquered and consolidated nationally, with international expansion. The processed pulps of these fruits are commercialized in different forms, from "fresh", preferably frozen, until the development of energetic drinks, ice cream and popsicle, sweets, juices, nectars, jellies etc. The cocoa fruit is used primarily for making chocolate, but it also provides a clear liquid extracted from the cocoa mass which cover the seeds, known as "cocoa's honey".

In Brazil, jellies can be produced with a single fruit (simple jelly) or by mixing two or more fruits (mixed jelly). The preparation of these types of products means higher value and income for this agribusiness (DAMIANI et al., 2008, YUYAMA et al., 2008; ZOTARELLI et al., 2008; FERREIRA et al., 2011; LAGO-VANZELA et al., 2011; GUILHERME et al., 2012).

According to the Technical Standards Relating to Food and Beverage, in Resolution no. 12, July 24, 1978 (BRASIL 1978) jelly fruit is the product obtained by cooking fruit, whole or in pieces, pulp or fruit juice, with sugar and water and concentrated to a gelatinous texture and can be subjected to addition of glucose or invert sugar. It cannot be artificially colored or flavored, being tolerated addition of pectin and acidulants, when necessary, to compensate any impairment of the natural content of the fruit acid and or pectin. The texture should be such that, when extracted from its container, is capable of maintaining the semi-solid state. A suitable combination of these components, both in quality and order placement during the processing, must be respected to ensure high quality of jelly (LAGO et al., 2006).

There are several ways to produce jellies, but generally the steps involved in processing are receiving the fruit, washing, pulping, addition of sucrose and pectin, concentration, filling, closing, cooling, labeling and storage. The final soluble solid content (expressed at [degrees] Brix) may vary between 60 and 72 and the final pH between 2.8 and 3.3, however the commercial formulation is determined by consumer preference (DAMIANI et al., 2008; YUYAMA et al., 2008; ZOTARELLI et al., 2008).

The objective of this study was to determine the chemical and physico-chemical characteristics and evaluate the sensory acceptability of mixed acai (Euterpe oleracea) and cocoa's honey (Theobroma cacao) jellies.

MATERIAL AND METHODS

This study was developed at the Nucleo de Tecnologia de Alimentos (NUTEC) of the Instituto Federal Baiano (IFBaiano), Campus Urucuca, BA. All the fruits of acai and cocoa used in this study were obtained from plants grown in IFBaiano, Urucuca municipality.

Preparation of cocoas honey and acai pulp and elaboration of jellies

After harvesting, cocoa and acai fruit were transported to the Pilot Factory of IFBaiano, Campus Urucuca, where they were selected to make the plot more uniform as the maturation stage and eliminate those fruit with mechanical injury or decay. Next, the fruits were washed and sanitized, for 15 minutes, in a solution of sodium hypochlorite (50 mg [L.sup.-1]) containing active chlorine. Cocoa's honey was extracted by pressing (Bonina, model ACLC-50, Brazil) and acai pulp by removing device in semi-industrial (Braesi, model DES-20, Brazil), after a previous cooking. Before the preparation of the jellies, was necessary to promote the dilution of acai using a rate 1:10 (w/w) of acai pulp and water. Jellies were obtained with different proportions of cocoa's honey (CH) and acai (A) using a rate 60:40 (w/w) of pulp and sucrose, plus citrus pectin 105 (Doce Aroma, Brazil) at 0.5% (w/w). Four treatments were studied: T1 (40% A:60% CH), T2 (50% A:50% CH), T3 (60% A:40% CH) and T4 (100% A--control).

After mixing the pulp and 75% of sucrose was measured the soluble solids content and pH, making the necessary adjustments (with addition of acid or base) to obtain a pH close to 3.0 which is ideal for making jelly (JACKIX, 1988).

The mixture was processed in an open pan with continuous mechanical movement (Incal Industrial Machinery, Brazil), for a period of 15 minutes.The addition of pectin is a critical step in the manufacturing process of jelly, therefore was added only at the end of the process so that it was not degraded by excessive cooking. The dissolution of the pectin was made by mixture of the pectin with the remaining 25% sucrose plus 150 mL of water at 60 [degrees]C under constant agitation.

When the jelly reached 63 [degrees]Brix was added pectin diluted and mixed vigorously in order to incorporate it into the product completely. After reaching 65 [degrees]Brix, the jelly was bottled at temperatures around 94 [degrees]C in heat-resistant plastic bottles of 150 g capacity. Then, the containers were sealed, cooled and the products were identified with labels and kept under room temperature.

Chemical and Physico-chemical characterization

The jellies were analyzed regarding titratable acidity (expressed as g of citric acid in 100 g-1 sample, direct titration of the material with 0.01N NaOH, pH in pHmeter Quimis, model Q400MT, Brazil, soluble solids content expressed as [degrees]Brix in digital refractometer Tecnal, model R2l300, Brazil, dry mater in oven with air circulation Tecnal, model TE-394/2, Brazil, total protein (%), lipid content and ascorbic acid (expressed as mg of ascorbic acid in 100 g-1 sample) according to the methodologies established by Instituto Adolfo Lutz (IAL, 2008). The total caloric values of the jellies were calculated from the centesimal composition data, using the conversion of following factors: 9 kcal g-1 lipid, 4 kcal g-1 protein, 4 kcal g-1 carbohydrate.

Mineral profile

The mineral profile of jellies was determined using atomic absorption spectrophotometry PerkinElmer, model 3030, USA, for Ca, Cu, Mg, Zn and Mn, molecular absorption spectrophotometry Varian, series 6345, USA, for Fe and flame photometry Micronal, model B-262, Brazil for K .

Sensory evaluation

Samples containing approximately 5 g of jelly were served in 50 ml plastic cups at room temperature. These were coded with three digit numbers and evaluated through an evaluation form, and the overall impression, spreadability, brightness, flavor, texture and color. Tasters were instructed to wash out the mouth with water filtered from sample to sample. The sensory acceptance test was conducted with 90 untrained tasters using a hedonic scale numerical of 7 points, with scores ranging from 1 (a) "dislike extremely" to seven (7) "like extremely." To be considered accepted, jellies should receive higher scores than the score (4) "indifferent" (ACOSTA et al., 2008).

Statistical design

For the chemical, physicochemical characterization and determination of the mineral profile of jellies, it was used a complately randomized design (CRD) with four (4) treatments and 4 (four) replicates. The results of sensory acceptability were evaluated by adopting the model of randomized block design (RBD), where treatments were four (4) formulations, blocks and repetitions were referring to the tasters. Comparisons between means were performed using analysis of variance (ANOVA) and Tukey test at 5% probability. Statistical analyzes were performed using the statistical program StatisticalAssistant, version 7.6 Beta.

RESULTS AND DISCUSSION

Chemical and Physicochemical characterization

The results of chemical and physicochemical characterization of mixed acai and cocoa's honey jellies are presented in Table 1. The titratable acidity value of the treatmentsT1, T2 and T3 ranged from 0.46 to 0.64%, being within the range of acidity recommended for most fruit jellies (YUYAMA et al., 2008; FOPPA et al., 2009; LAGO-VANZELA et al., 2011). The titratable acidity of the control treatment (T4) with 100% of acai pulp was 0.20%. Thus, it was observed that the variation of the titratable acidity in the other treatments is directly associated with the gradual increase of concentration of cocoa's honey. Regarding to pH, it was found that the same has been reduced due to the higher proportion of cocoa's honey used in the formulation. Similar result was found by Ferreira et al. (2011) with mixed watermelon and tamarind jelly, where the addition of tamarind promoted an increase in acidity of jelly. The soluble solids content of the treatments ranged between 65.2 [degrees]Brix (T3) and 65.5 [degrees]Brix (T1). Similar values were found by Viana et al. (2012) in papaya and araza boi jelly (63.9 to 65.4 [degrees]Brix) and by Damiani et al. (2012) in mixed araca and marolo jam (68,40 to 72,18 [degrees]Brix. These results also corroborate those reported by Damiani et al. (2008) who obtained the fruit jellies with total soluble solids content in the range of 65 [degrees] Brix.

However, these values are lower than those obtained by Lago-Vanzela et al. (2011) for mangoes jellies (69 [degrees]Brix) and by Singh et al. (2009) for mixed pineapple and papaya jelly (70.5 [degrees]Brix) and papaya with orange (72.5 [degrees]Brix). Mota (2006), in a study of jellies formulated with different varieties of blackberry, found lower levels of soluble solids content (47-58 [degrees]Brix) than in the present study. According to Jackix (1988) the soluble solids ideal for jellies are 67.5 [degrees]Brix, and to lower values (64 [degrees]Brix), the gel becomes weaker and above (71 [degrees]Brix) can occur crystallization of the jelly.

The dry matter content of the four treatments ranged from 60.24% (T3) to 62.44% (T1), which means that moisture ranged from 35.56% (T1) to 39.76% (T3), similar to levels found in the Lago et al. (2006) and Lago-Vanzela et al. (2011) study in jelly of jambolan (29.6%) and otaheite apple (29.5%). respectively. Mota (2006) found higher moisture contents (42.84 to 46.44%) in jellies made from different varieties of blackberry. According to Viana et al. (2012), the moisture content in jellies is directly related to the conservation of the product during storage.

The total protein content of the treatments T1, T2 and T3 was 0.44%, 047% and 0.51%, respectively. The control treatment (T4), prepared only with acai pulp was 0.54%. Cocoa's honey and the acai pulp present low protein concentration. Smaller amounts of proteins also were found by Granada et al. (2005), studying pineapple jelly (0.21%, 0.22%, 0.26% and 0.28%), and by Foppa et al. (2009) at Housui and D'agua pearjelly (0.17%). Lago-Vanzela et al. (2011) found higher levels in pulp and peel "caja manga" jelly (1.47%).

The lipid content in the control treatment (5.51%) is considered high when compared with other jellies (YUYUMA et al., 2008; LAGO-VANZELA et al., 2011). This fact probably is associated with the higher concentration of lipids present in the fruit of acai and its pulp. Compared to the lipid content of others treatments (T1, T2 and T3), 3.50%, 3.66% and 3.95%, respectively can be deduced that the addition of cocoa's honey decrease the concentration of this nutrient. Yuyama et al (2008) studying cubiu jellies with xylitol and with sucrose found lipid content of 0.34% and 0.38%, respectively.

There is little information in the literature on the content of ascorbic acid in jellies. In the control treatment, the ascorbic acid content was 28.96 mg 100 g-1. In comparison to the other treatments (T1, T2 and T3), 13.08%, 10.87% and 10.36%, respectively, it was found that the addition of cocoa honey also influenced the decrease in concentration of that nutrient. The amount of calories of the treatments T1, T2 and T3 ranged from 303.09 kcal 100 g-1 to 305.62 kcal 100 g-1.

The results of the mineral profile of mixed acai and cocoa honey jellies are presented in Table 2. No difference was observed between the formulations with respect to P element. With respect to the element K, there was no difference between the formulations T1, T2 and T3. However, there was difference between the three formulations and the standard T4. The Fe content of the treatments T3 and T4 did not differ each other, however, there was difference between the other treatments T1 and T2. Also, was observed a difference between the formulations for Ca and Mn. Among the fractions of minerals present in the mixed acai and honey cacao jellies presented in the Table 2, the Fe element, due its importance, deserves mention, because it showed levels ranging from 32.70 mg 100 g-1 (T4) to 71.11 mg 100 g-1 (T1) equivalent, on average, four times higher the recommended daily dietary intended for an adult, considering a 100 g portion of the product. The mineral element, phosphorus, showed levels within the recommended daily value and Mn exceeded by ten times the daily value, considering the portion of 100 g of the product, since the fractions of K, Ca, Mg, Zn and Cu showed up at low of the daily values.

Sensory acceptance

The results of the sensory acceptance of mixed acai and cocoa's honey jellies are presented in Table 3. It was observed that none of the treatments presented score below 4, that correspond to the rejection zone (CAMARGO et al., 2007), according to hedonic scale of 7 points used. So it can be inferred that the products presented acceptable sensory characteristics for marketing. However, there was statistically significant differences (p <0.05) between the treatments except flavor and texture attributes.

There were variations in the preference of the jelly with regard to these attributes, since the treatment T1, with more cocoa's honey, presented a better acceptance, with scores between 5.0 and 6.0, corresponding to the hedonic terms "like moderately and like much", respectively. Zotarelli et al. (2008) observed that in mixed guava and passion fruit jelly, the higher concentrations of guava benefited the acceptance of the product by the judges. Ferreira et al. (2011) also found that the addition of watermelon improved acceptance of tamarind jelly. Regarding the flavor attribute, when compared with the control treatment (T4), it was found that the addition of honey cocoa did not affect sensory acceptance of jellies (T1, T2 and T3), which maintained the characteristic flavor of acai.

Damiani et al. (2008) explained that the texture of the jelly is the result of two factors of the structure: gelling, linked to the concentration of pectin, and stiffness, related to the concentration of sugar and acid. The cocoa's honey is a product known for its acidity and high levels of sugar and pectin and its addition contributed to the improve flavor and especially texture of jelly. However, there was no significant influence over these two attributes.

There was no significant difference (p < 0.05) between the treatments T1 and T2, T4 and T3, with reference to the attribute spreadability. The spreadability is directly related to the uniformity and rigidity of the gel formed and the resulting gel structure which is connected to the concentration of pectin, sugar and acid. Thus, the amount of pectin added, as well as the intrinsic characteristics of cocoa's honey influenced positively this attribute.

CONCLUSIONS

The treatments showed significant differences with respect to mineral contents, except for P and.

Every formulations of mixed jellies presented good sensory acceptance but the treatment T1 (40% acai: 60% cocoa's honey) presented the higher scores for the evaluated attributes.
