A typical fruit of this region is Guapeva (Pouteria gardneriana Radlk), which has a sweet taste, high nutritional content, and antioxidant action in the human body. This study aims to evaluate the physicochemical properties of Guapeva peel processed into flour. With the fruit acquired and sanitized, the peel was separated, and a portion of it was taken to the oven at 60°C for 18 hours. Subsequently, analyses of pH, moisture, total soluble solids, vitamin C, and total phenolics were carried out on the dehydrated peel. Water and oil absorption analyses and gel formation capacity were performed only on the dehydrated peel. The results obtained for the fresh peel were 6.00; 78.05%; 11 °Brix; 1.09 mg/100g; 0.07 mg GAE, respectively, followed by the dehydrated peel, which were 6.00; 10.85%; 19.5 °Brix; 0.47 mg/100g; 1.35 mg GAE; 7 g/g; 4.5 g/g, with good gel formation in 10% flour. Guapeva peel flour showed satisfactory physicochemical results, proving to be a viable alternative for better utilization of this residue.

This study aimed to analyze the physicochemical characteristics of fresh and dehydrated murici. The fresh and dehydrated fruits were analyzed for pH, total titratable acidity (TTA), moisture, and total soluble solids (TSS) parameters. The fresh fruit presented pH, TTA, moisture, and TSS values of 4.76, 2.61 g/100 g, 68.85%, and 12.33 °Brix, respectively, while the dehydrated murici showed values of 6.23, 4.01 g/100 g, 21.24%, and 33.66 °Brix, respectively. The results showed discrepancies when compared to those reported in the literature. These differences may be attributed to the fruit characteristics, endoclimatic factors, and analytical methodology.

A major problem faced in the cajuzinho-do-cerrado production chain is its conservation, as it is an extremely perishable fruit due to its high water activity. Osmotic dehydration used as a pretreatment, followed by drying, is a good alternative to reduce water activity and facilitate transportation, as well as to add value. The objective was to characterize the biometric and physicochemical properties of the samples. Analyses were carried out for pH, moisture, acidity, ash content, vitamin C, phenolics, total soluble solids, total reducing sugars, browning index, color, GS, PA, and RM in fresh samples, osmotically dehydrated samples, and after drying at 70°C. For moisture content, the sample dried with glucose had the lowest content, inversely proportional to the total soluble solids found. For vitamin C content, the fresh sample had the highest content, but as the processes progressed, it degraded as expected. It is concluded that the processes employed in this study were efficient. The best treatment identified was the sample dried with glucose, as reducing moisture content can prolong the shelf life of cajuzinho-do-cerrado.

Faced with this scenario, the food industry employs various technological processes such as sterilization, irradiation, drying, addition of additives, among others, in order to control this type of contamination. On the other hand, nowadays it is becoming common for people to prefer to consume naturally preserved food, that is, food that has undergone less aggressive treatments, without the use of synthetic additives. Given this reality, essential oils extracted from condiment plants have shown great promise, considering that they are a natural source of antimicrobial substances. In this context, the aim of this study was to evaluate the antimicrobial action of the essential oil of Zingiber officinale roscoe in samples of fresh sausage artificially inoculated with the pathogenic bacteria escherichia coli, staphyloccocus aureus and salmonella typhimurium) for 24, 48 and 72 hours of contact (oil x bacteria) using a concentration of 20 µL of essential oil. It was shown as a promising source of efficient natural antimicrobial agent to be used in meat products in the concentration evaluated for pathogenic bacteria.
