Dried sugar–egg powders, obtained from a commercial Canadian source, were adjusted to 1.4, 2.8, and 3.2% moisture and stored at 40°, 80°, and 120° F. from 1 to 52 weeks. Quality of the powder was assessed by measurement of fluorescence, potassium chloride value, pH, and foaming volume. The rate of deterioration increased with an increase in moisture content at 80° and 120° F. The effect of moisture content on fluorescence and potassium chloride values was negligible at 40° F., but high moisture in powders stored at this temperature accelerated the development of acidity and the loss in baking quality as assessed by foaming volume.Packing in carbon dioxide, nitrogen, and in vacuo had a slight beneficial effect on dried sugar–egg powder.

HighlightsHA-RF disinfestation treatment had better pre-drying effect of rough rice than that of HA treatmentHighest moisture loss (8.7%) was obtained for samples with highest IMC (39.6% d.b.)Initial moisture content (IMC) correlated negatively with milling quality of rough riceHA-RF can be used as a pre-drying method to partially reduce the moisture contentAbstract.Hot air-assisted radio frequency (HA-RF) is an environmentally friendly disinfestation method, which can completely control the insects and meanwhile maintain quality of rough rice. In this study, the pre-drying effect of HA-RF disinfestation treatment of rough rice with different initial moisture contents (IMCs) (16.7%, 24.8%, 34.7%, and 39.6% d.b.) was investigated along with associated quality change. HA-RF treatments had better pre-drying effect of rough rice with various IMCs than that of hot air (HA) treatment and larger electrode gap obtained lower moisture removal. IMCs of rough rice also influenced the moisture removal for HA-RF treatments, and the corresponding moisture loss were 4.3%, 5.3%, 6.1%, and 8.7% for the treated rough rice with IMC of 16.7%, 24.8%, 34.7%, and 39.6%, respectively. More quality loss was observed for the rough rice with higher IMC, especially for broken rate, fissure, and water uptake ratio. HA-RF treatment had no influences on total phenolic acids, protein, and fat contents, but amylose and vitamin E contents were affected. Non-milled rice treated by HA-RF had an obvious decrease in the lightness (L*) except for the samples with highest IMC (39.6%). RF disinfestation treatment can be used as a pre-drying method to partially reduce the moisture content (MC) of rough rice. Keywords: Disinfestation, Moisture content, Pre-drying, Quality, Rough rice.

The crispiness is an important parameter of battered chicken meat products and could be improved by adding leavening agents such as baking powder and dried yeast. This work was aimed to study the effect of different leavening agents added on the quality characteristics of battered chicken meat. Chicken breast meat strips were dipped into batters using different type of leavening agent; control (without a leavening agent); 4% baking powder (1), 4% dried yeast (2) and 2% baking powder + 2% dried yeast (3). The batter was kept in room temperature (RT) and cold temperature (CT) for one hour after coating. Moisture content, fat content, the viscosity of batter formulation, color, texture and sensory of fried battered chicken meat strips were evaluated. Moisture contents of RT3 and CT3 were significantly higher compared to other treatments while the fat content and viscosity of RT3 and CT3 were among the lowest. The RT2 and CT2 resulted in the lightest color. Compared to control samples, the addition of baking powder and yeast increased crispiness (fracturability and hardness) which was higher when used in combination than alone. Sensory evaluation of quality attributes showed crispiness and overall acceptability for RT3 and CT3 were among the highest. From the experiment, formulation 3 displayed the best effect of the leavening agents (a combination of baking powder and dried yeast) in batter system which produced lower fat, high moisture content, and crispier deep-fried chicken breast meat.

The actual challenge for the food industry is the utilization of by-products of fruit and vegetable processing and their use in the production of enriched food products. It allows to use raw materials with a high content of biological active substances more efficiently and rationally. The possibility of using carrot bagasse as an ingredient in the preparation of extruded ready-to-eat product was studied. The wheat meal was used as core ingredient. The influence of the bagasse dosage on the extrusion conditions and the properties of the extrudates samples was studied. It was shown that an increase of the bagasse content more than 20% influenced the quality of the product negatively.The expansion index decreased more than 2 times and the bulk density increased by 40%. The method of additional steam venting from the middle part of the extruder chamber was investigated during the extrusion cooking of mixtures with the bagasse content more than 20% and moisture content 26.5, 28.9 and 34.5%.The indicator of the steam venting was the reduction of pressure in the degassing installation. As a result, the moisture content of the material in the die zone of the extruder chamber decreased. It was shown that additional steam venting during extrusion of high-moisture mixtures led to more severe extrusion conditions. The temperature, die pressure and torgue increased significantly. It imroved the quality of extrudates. Steam venting during extrusion of blends with 26.5 and 28.9% moisture increased expansion index more than 2 times and decreased the bulk density by 21-25%.Extrusion process of a mixture with a moisture content of 34.5% without and with steam venting was unstable and did not allowed to obtain samples of extrudates with acceptable quality. The proposed method for extrusion of high-moisture blend of wheat flour with carrot bagasse can be basis for developing technologies for the production of ready-to-eat extruded products using moist food by-products of fruits and vegetables processing.

ABSTRACT The objective of this study was to evaluate the quality of second-crop corn harvested with different moisture contents as a function of time before drying. The corn grains were harvested with moisture content of 28.5, 22.4, 21 and 19%, and submitted to a temporary storage for ten days, simulating the time between harvesting and drying. Quality was subsequently evaluated every two days, based on the commercial classification of the grains, sanity test and dry bulk density. The results showed that: the increase in moisture content at harvest affects the physical and sanitary quality of second-crop corn, and this effect is aggravated over time; the moisture content of 19% is the one that least affects grain quality during the ten days of temporary storage.
