Two probiotic bacteria (Lb. acidophilus and B. lactis) were immobilized on the alginate coat of strawberry pieces and were added to the prepared sweet non fat dietary stirred yogurt. Physico-chemical parameters namely pH value, titratable acidity and synersis along with the viability of probiotic bacteria of the samples were evaluated over the 8 days of storage at 5 ºC at 2 day intervals. A sig...

Electrical heating of food products provides rapid and uniform heating, resulting in less thermal damage to the product. The objective of this research was to examine the effects of ohmic heating on the stability of orange juice with comparison to conventional pasteurization. During storage at 4 degrees C, degradation curves of ascorbic acid followed a linear decrease pattern in both ohmic-heat...

This study was conducted to evaluate the titratable acidity and effect of naturally acidic agents on the surface microhardness, elemental composition, and surface morphology of fluorapatite-leucite ceramics. One hundred and ten ceramic disks (IPS d.SIGN), 12.0 mm in diameter and 2.0 mm in thickness, were fabricated. Before immersion, the baseline data of Vickers microhardness and elemental comp...

ABSTRACT: Edible coatings made from whey protein concentrate (WPC) and gellan gum (G) were investigated for their capacity to preserve the quality of Malus domestica cv Golab apples. WPC and gellan gum coatings at different concentrations plasticized with glycerol (Gly) were tested. Postharvest storage quality condition testes included weight loss, color and texture changes, titratable acidity ...

In the present work, survival of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) on artificially infested ‘Clemenules’ clementine mandarins (Citrus reticulata Blanco) was assessed on fruit subjected to integrated quarantine treatments consisting of irradiation with X-rays at doses of 0 (control), 30, 54, and 164 Gy followed by exposure to 1°C for 0 (control), 3...

The probiotic juice is one of the newest innovation opportunities in various kinds of healthy drinkꞌs business. The aim of this study was to investigate effect of banana pureeꞌs on survival of Lactobacillus casei and physicochemical and sensory properties of cocktail juice containing apples and bananas juice during storage. The amounts of banana puree were added in 3 levels (7% and 15%) to appl...

Yogurt is the most important fermented dairy product. However, its per capita consumption in Iran is low. Production of flavored yogurt to create a variety of products can cause customer satisfaction and increase in per capita consumption. Flavored yogurt at three levels: 0.1, 0.3 and 0.5 were prepared by adding Zoulang aqueous extract. The systems were prepared by following a factorial design,...

1. In six volunteers, the effect of intragastric administration of different water-soluble chemical isolates of dietary fibre on gastric secretion, acidity and emptying was studied. 2. At 30 min after administration of the test meals, the stomach contents were completely aspirated and the volume, pH, phenol red concentration, total titratable acidity and different electrolytes were measured. 3....

Twenty-eight apple cultivars were selected for their potential hard cider production in Ontario; juice characteristics measured 2017 and 2018, beginning two years after planting 2015. After being harvested pressed, each sample underwent analyses to determine soluble solids concentration (SSC), titratable acidity (TA), pH, yeast assimilable nitrogen (YAN), polyphenolic concentration. Soluble ran...

The formation of 2-furoylmethyl derivatives of GABA (2-FM-GABA) and arginine (2-FM-Arg) as early indicators of nonenzymatic browning in different types of orange juice was studied. In dehydrated orange juice, the presence of 2-FM-GABA and 2-FM-Arg was detected from the first day of storage at 30 degrees C. In this type of juice, the content of these two compounds increased with temperature (30,...
