Effects of deep fat frying and hot air frying on texture, color difference, sensory score, yield, fat content, and volatile flavor compounds of giant salamander meatballs before and after frying were investigated. The results showed that, compared with the deep fat frying group, hot air-fried giant salamander meatballs had higher hardness, elasticity, and L ∗ ( p < 0.05 ), but lower a ∗ , b ∗ value, fat content, and yield ( p < 0.05 ). There was little distinction in sensory score, cohesiveness, and chewiness between the two frying methods ( p > 0.05 ). Gas chromatography ion migration chromatography (GC-IMS) was used for flavor compound analysis, and 50 flavor compounds were analyzed, containing 22 aldehydes, 11 ketones, 6 olefins, 4 acids, 3 esters, 3 alcohols, and 1 phenol. Compared with the samples before frying, the relative contents of aldehydes and ketones of fried giant salamander meatballs increased significantly, while the relative contents of esters and alkenes decreased significantly. Principal component analysis showed that the GC-IMS spectra of volatile flavor compounds before and after deep fat frying and hot air frying varied greatly, and the cumulative contribution rate of the two principal components reached 86.1%, indicating that the GC-IMS technology might be used to distinguish giant salamander meatballs before and after frying, or with different frying methods. These results may offer a note for development and quality control of the precooked giant salamander meatballs in the future.

The fat content of fried pork rinds is high, and alternative frying helps reduce the oil content and maintain their texture and taste. Different frying methods such as microwave-assisted, traditional deep frying and vacuum frying on the breaking force, color, microstructure, water loss and oil absorption attributes of fried pork rinds were evaluated in this study. The fat content of microwave-assisted and vacuum-fried pork rinds was lower (24.2 g/100 g dry weight basis (db) and 17.1 g/100 g db, respectively) than that (35.6 g/100 g db) of traditional deep-fat frying. Non-uniform, holy and irregular surface microstructures were obtained by vacuum frying due to rapid mass transfer at low pressure. The first-order kinetic models of water loss and oil absorption of traditional and microwave-assisted frying of pork rinds were established. Microwave frying caused a faster moisture loss rate, shorter frying time and lower pork rind oil content, makes it an attractive substitute for traditional deep-fat frying.

Зерновые энергетические батончики, пользующиеся большим спросом у потребителей, удобны для введения в рацион полезных для здоровья питательных веществ и функциональных соединений. Исследовано влияние базовых компонентов – взорванных зерен риса, амаранта и киноа на содержание белка, жира, общего пищевого волокна, показатели твердости и общей приемлемости в зерновых энергетических батончиках. Установлено, что содержание белка и жира в образцах батончиков повышалось по мере увеличения в их составе доли зерен киноа и амаранта. Повышение содержания жира привело к снижению содержания углеводов в составе зерновых батончиков. Образцы изготовленных батончиков в зависимости от соотношения зерновых компонентов могут содержать до 7,76% клетчатки, что позволяет классифицировать такое изделие как функциональный пребиотический продукт. Добавление волокнистых ингредиентов влияет на текстуру продукта, повышает твердость, улучшая жевательность и адгезию. Показатель общей приемлемости изготовленных образцов зерновых батончиков варьировал от 5 до 7,9 баллов при 9-балльной оценке. Самую высокую оценку получил образец с равным содержанием в рецептуре взорванных зерен киноа, амаранта и риса, а также отмечены образцы с более высоким содержанием (66,67%) взорванных зерен киноа и амаранта. Grain energy bars, which are in high demand among consumers, are convenient for introducing healthy nutrients and functional compounds into the diet. The influence of the basic components – blasted rice grains, amaranth and quinoa on the protein, fat content, total dietary fiber, hardness, and overall acceptability in grain energy bars was studied. It was found that the content of protein and fat in the samples of bars increased as the proportion of quinoa and amaranth grains in their composition increased. The increase in fat content led to a decrease in the carbohydrate content of cereal bars. Samples of manufactured bars, depending on the ratio of grain components, can contain up to 7,76% fiber, which allows us to classify such a product as a functional prebiotic product. The addition of fibrous ingredients affects the texture of the product, improving the hardness, chewiness and adhesion. The overall acceptability of the manufactured samples of grain bars ranged from 5 to 7,9 points with a 9-point rating. The highest rating was given to a sample with an equal content of exploded quinoa, amaranth and rice grains in the formulation, and samples with a higher content (66,67%) of exploded quinoa and amaranth grains were also noted.
