Before And After

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.

Banana Leaf

The objective of the research was to identify volatile flavor compounds and odor description of tempeh wrapped with banana leaf and plastic fermented at different times. The research object was tempeh wrapped with banana leaf (TD) at 48 (TD1H), 72 (TD2H), and 96 hours (TD3H) fermented, and tempeh wrapped with plastic (TP) at 48 (TP1H), 72 (TP2H), and 96 hours (TP3H) fermented. Sample was extracted by SPME. GC-MS/O was used to identify volatile flavor compounds and odor description. The volatile flavor compound found in tempeh were group of ester, terpenoid, alcohol, aldehyde, ketone, furan and nitrogen containing compound. α-pinene was only found in tempeh wrapped with banana leaf, whereas piperazine, sec-butyl nitrite and (Z)-α-bisabolene were only found in tempeh wrapped with plastic. This revealed that there was difference flavor compound found in tempeh wrapped with banana leaf and tempeh wrapped with plastic. ABSTRAKPenelitian ini bertujuan untuk mengetahui komponen penyusun flavor volatil dan aroma tempe yang dibungkus daun pisang dan plastik pada waktu fermentasi yang berbeda-beda. Tempe yang digunakan sebagai objek penelitian adalah tempe yang dibungkus dengan daun pisang (TD) dengan waktu fermentasi 48 jam (TD1H), 72 jam (TD2H), dan 96 jam (TD3H) dan tempe yang dibungkus plastik (TP) dengan waktu fermentasi 48 jam (TP1H), 72 jam (TP2H), dan 96 jam (TP3H). Ekstraksi sampel tempe menggunakan HS-SPME. Analisis flavor dan deskripsi odor dilakukan dengan menggunakan GC-MS/O. Senyawa flavor tempe yang diperoleh adalah senyawa-senyawa dari golongan ester, terpenoid, alkohol, aldehid, keton, furan dan senyawa-senyawa yang mengandung nitrogen. α-pinen hanya ditemukan pada tempe yang dibungkus daun pisang, sedangkan piperazin, sec-butil nitrit dan (Z)-α-bisabolen hanya ditemukan pada tempe yang dibungkus plastik saja. Hal ini berarti ada perbedaan komponen penyusun senyawa flavor pada tempe yang dibungkus daun pisang dan plastik.

Significant Difference

A 1:1 mixture of Leuconostoc and Lactobacillus plantarum and of L. plantarum alone were used as starter-cultures in making two batches of summer sausage. Sausage samples were evaluated for volatile flavor compounds and by sensory evaluation. Ethanol was the primary volatile flavor compound in the sausage from mixed culture while acetaldehyde predominated in the single culture sausage. Sensory evaluation indicated a significant difference (p≤0.01) between the two types of sausages with 66% of the panelists preferring sausage prepared with L. plantarum alone.

Volatile Flavor

This study optimized the headspace solid phase microextraction (HS-SPME) conditions for the analysis of the volatile flavor compounds of Chinese south stinky tofu brine by gas chromatography-mass spectrometry (GC-MS). The optimum HS-SPME conditions established were as follows: polar column CD-WAX, white 85 μm polyella extractor, extraction temperature 60 °C, equilibrium time 20 min, extraction time 40 min. Under these conditions, a total of 63 volatile flavor compounds in five stinky tofu brines were identified. The offensive odor of the stinky tofu may be derived from some of the volatile flavor compounds such as phenol, p-cresol, 3-methylindole, indole, acetic acid, propionic acid, isobutyric acid, n-butyric acid and 3-methylbutanoic acid. The volatile flavor substances data was examined by principal component analysis (PCA) to visualize the response patterns in the feature space of principal components (PC). PCA analysis results revealed that the Chengshifu brine (STB1) and Baise jingdian brine (STB4) are similar in PC 1, 2, and 3, and the two brines have a similar flavor. Results also indicate that the Huogongdian brine (STB2) and Wangcheng brine (STB3) can be grouped in the same class as they are similar in PC 3. However, PC 1, 2, and 3 of the Luojia brine (STB5) and other brands of brine are different as is the flavor.
