Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...

The present study aimed to evaluate the drying quality of three tomato cultivars (Amoroso, Berlinto and Messina) at low final-moisture content. Tomatoes were cut into slices and hot-air-dried from 92% (wet basis) to 12% final moisture content at 55 degrees C, 65 degrees C and 75 degrees C at 1.5 m/sec air flow. Color, total soluble solids (TSS), titratable acidity (TA) and ascorbic acid (AA) co...

The aim of the present study was to estimate genetic parameters for calcium (Ca), phosphorus (P) and titratable acidity (TA) in bovine milk predicted by mid-IR spectroscopy (MIRS). Data consisted of 2458 Italian Holstein-Friesian cows sampled once in 220 farms. Information per sample on protein and fat percentage, pH and somatic cell count, as well as test-day milk yield, was also available. (C...

‘In-store’ consumer acceptance tests were performed on a group of 400 American consumers and 250 native Chinese consumers to determine the relationship between ripe soluble solids concentration (SSC) and titratable acidity (TA) on consumer acceptance of ‘Redglobe’ grapes for different ethnic groups. For this, a group of Caucasian, Hispanic and Chinese-American consumers and a group of native Ch...

The objective of this study was to evaluate the use lemon essential oil and its mixtures with chitosan, calcium chloride, natamycin on postharvest storage quality citrus. analysis physiological biochemical index changes citrus stored at 20 ± 2 °C 75 5% relative humidity for 60 days showed that could help maintain nutritional sensory In addition, increased activities superoxide dismutase (SOD), ...

Wheat, pretreated by 60Co gamma irradiation, was dried by hot-air with irradiation dosage 0-3 kGy, drying temperature 40-60 °C, and initial moisture contents 19-25% (drying basis). The drying characteristics and dried qualities of wheat were evaluated based on drying time, average dehydration rate, wet gluten content (WGC), moisture content of wet gluten (MCWG)and titratable acidity (TA). A qua...

'Early Rich', 'Royal Glory', 'Sweet Dream(cov)', and 'Elegant Lady' peaches were stored at -0.5 °C for up to 40 days and then subjected to ripening at 20 °C for up to 3 days. Firmness, soluble solids content (SSC), titratable acidity (TA), color, consumer acceptance, and volatile compounds were then determined. The observed physicochemical changes included a significant decrease in firmness dur...

The effects of edible coatings based on gum arabic (GA) (0.5–1.5%), maize starch (MS) lemongrass oil (LO) (2–4%), and glycerol (GC) (0.5–1%) developed using response surface methodology (RSM) “Wonderful” pomegranate fruit were studied. After 42 days storage (5 ± 1 °C, 95 2% RH) 5 at ambient temperature (20 0.2 °C 60 10% RH), whole evaluated for weight loss (%) juice (PJ) total soluble solids (°...

The objective of this work was to formulate and characterize chemically physically different formulations camu-camu jellies, with or without mixture other fruits. Their sensory acceptance evaluated by identifying the greater acceptability while maintaining their nutraceutical potential. were: jelly, jelly jabuticaba, guava, acerola, passion fruit papaya. Untrained tasters were used assess consu...

‘zaferani’ peach, an important native iranian fruit, is a highly perishable fruit of limited shelf life. in the present research, effects of modified atmosphere packaging with three gas combinations (5% co2 + 2% o2, 10% co2 + 2% o2 and air) and two packaging films (polypropylene and low density polyethylene (ldpe)) on physicochemical characteristics and shelf life of 'zaferani' peach ...
