Starch and protein are two important components in food system. The interactions between starch and protein have important influence on the structure, physicochemical properties of starch and the texture and digestibility of starch-based food. In recent years, the effect of exogenous protein on starch-protein interaction in mixed system and its application have become a hot research topic in the field of food. This article reviews the interaction mode between starch and protein, the effect of protein on physicochemical properties （gelatinization properties, retrogradation properties, rheological properties, thermal properties and texture properties） and microstructure of starch-protein mixed system, summarizes the regulation effect …

Objective: This study aimed to investigate the effect of slaughtering methods on the muscle quality of eels. Methods: Two slaughtering methods （including mechanical slaughter and manual slaughter） were used to analyze the energy metabolism and physicochemical properties of eel meat slices during storage. Results: Duringstorage at 4 ℃ for 48 h, the glycogent and lactic acid content of eelfillets subjected to mechanical slaughter were lower than those of manual slaughtered samples generally. During 7 d-storage, the sensory deterioration of eel meat samples was retarded by mechanical slaughter, and the TVB-N and TBARS content were lower than those of manual slaughtered …

Objective: To improve the availability of cherry seed, cherry seed oil was extracted by the aqueous enzymatic method. Methods: the ratio of mixed enzymes was optimized by mixture design on the basis of single factor experiment. The basic indexes of oil such as fatty acid composition and physical and chemical properties were detected. Results: the optimum extraction conditions were a 2.0% addition of mixed enzyme comprising cellulase, pectinase and acid protease （0.67∶0.10∶0.23）, liquid to material ratio of 10∶1 (mL/g), enzymolysis temperature of 45 ℃, pH of 4.0 and time of 4.0 h. The recovery of oil was 93.18% and the …

In this study, two kinds of edible fungus Sporisorium reilianum and Pleurotus eryngii were used as raw materials. Soluble dietary fiber (S-SDF, P-SDF) and insoluble dietary fiber (S-IDF, P-IDF) were prepared by enzyme-gravimetric method. The physicochemical properties including swelling capacity, water holding capacity and oil holding capacity, and the functional properties including glucose adsorption capacity, sodium cholate adsorption capacity, cholesterol adsorption capacity and glucose dialysis retardation index were measured respectively. Results showed that S-SDF had the strongest swelling force (11.83 mL/g). P-IDF had the strongest water holding capacity (4.55 g/g). P-SDF had the strongest oil holding capacity (3.01 g/g). S-IDF …

A calibration model of near-infrared spectroscopy for the determination of water and total sugar is established and optimized in order to realize the rapid detection of physical and chemical indexes of marzipan. The partial least square method is used to establish NIR calibration models for the determination of water and total sugar in marzipan. Then, the abnormal sample removal, spectral transformation, sample set partition and characteristic wavelength selection are used to optimize its performance. The results show that the number of modeling wave points of the moisture determination model is reduced to 0.8% of the total spectrum, R and R …
