| Abstract: Bottle gourd (Langenariasiceraria), Aonla (EmblicaofficinalisGaertn.), Lemon (Citrus x limon) and Ginger (Zingiberofficinale) juice was blended in the proportion of 87.90: 23.40: 5.70: 6.00 mL, respectively. Prepared blend juice was hot filled in glass bottles and thermally processed over a temperature range over 80-950C for 5-30 min. Significant difference was observed in ascorbic acid (vitamin C), total plate counts and, yeast and mould counts (P<0.05), while no significant difference was in pH and TSS (P>0.05). The best thermal process was found at 85°C hot filling and processing at 85°C for 5 min. At this temperature-time combination, 3.52 pH, 5.17 oBrix TSS, 38.32 mg per 100 mL ascorbic acid, 35 cfu mL-1 total plate counts, 2... |

| Guava nectars were formulated for approximately 10, 12, or 14 ºBrix, with 40% guava pulp. Sodium benzoate, 500 mg.kg-1 was used as preservative. The Brix value was adjusted with saturated sucrose syrup. The guava nectar was pasteurized (85 ºC/42 seconds) in tubular heat exchanger and then hot filled in 500 mL white glass bottles. The products were stored either at room temperature (25 ± 5 ºC) or refrigerated (5 ± 2 ºC) under fluorescent light exposure and analyzed on the day after processing (time zero) and also 40, 80, and 120 days of storage. Eight compounds were identified and quantified by Gas Chromatography (GC) -Mass Spectrometry (MS): hexanal, (E)-hex-2-enal, 1-hexenol, (Z)-hex-3-enol, (Z)-hex-3-enyl acetate, phenyl-3-propyl acetate, cinnamyl... |

| Abstract: The objective of this work was to evaluate the effects of zinc concentration in acidified brine and of pasteurization time on the zinc content, color, and physicochemical and microbiological characteristics of canned vegetable-type soybean (Glycine max). The 22 central composite rotational design (CCRD) was used, with zinc concentration in the acidified brine and duration of pasteurization as variables, resulting in 12 assays. A canning formulation was developed and compared with canned-vegetable type soybean without zinc and with fresh-vegetable type soybean, with microbiological evaluation. Zinc addition within the limits defined by Food and Drug Administration (≤75 ppm) does not affect the physicochemical and microbiological characteristics of... |
