Abstract Manual labor involved in shrimp extraction selection accounts for an extremely high proportion of processing time and also entails reduced accuracy and efficiency moreover even it could induce potential safety hazards. The key to substitute the manual process with automation lies in the identification and pinpointing of the penultimate joint in shrimps. Therefore, a cascaded neural network is proposed in this study to implement the detection of key points in a multi-shrimp scenario processing. More specifically, our model includes two stages: a shrimp detector based on YOLOv3 and followed by a pose estimator based on Convolutional Pose Machine (CPM). With the combination of attention mechanism and improved NMS strategy, our detector is equipped to resist noise interference in dense case, ubiquitous on the production line. Experimental results indicate that both the detection rate and the speed information extraction have achieved the standard of industry applications.

Abstract This study elucidated the effect of wavelength, radiant fluence, and pH on the photobleaching of red cabbage extracts (RCE). Light-induced degradation of anthocyanins (ACN), color, total phenolic content (TPC), and antioxidant activity of RCE was evaluated. Blue light was found to have the most detrimental effect on red cabbage ACN, followed by white and green lights. The photo-degradation increased with pH and radiant fluence. The highest loss of ACN was estimated at pH 7, being about 91 %, 76 %, and 54 % under blue, white, and green light, respectively. Color attributes and antioxidant activity of the samples showed similar trends. The photo-degradation quantum yield was higher under blue light (pH 3: 0.46 × 10−4 mol einstein−1; pH 5: 4.5 × 10−4 mol einstein−1; pH 7: 4.5 × 10−4 mol einstein−1) than under other irradiations. The findings can help industrial processors devise suitable strategies to minimize the degradation of ACN under LED illumination.

Abstract Lactose and sodium caseinate were used as wall materials in microencapsulation of fish oil by spray drying. Thyme, rosemary, and laurel extracts were utilized to enhance oxidative stability. Efficiency of antioxidant capacity of plant extracts was compared with BHT. Fish oil encapsulates with rosemary extract exhibited better protection against lipid oxidation (0.36 mmol MDA/kg) than the control group (2.92 mmol MDA/kg) at +4 °C. Hue angle properties of encapsulated fish oil with the laurel extract showed the highest change. The lowest peroxide value (PV) was detected in the 1500 ppm rosemary group (5.13 mEq O2/kg oil) and 250 ppm BHT group (5.90 mEq O2/kg oil) after the spray drying. Also, these groups had the lowest TBARs values during the storage. It was observed that the pAV of CG2 (BHT Control), RE1 (1000 ppm rosemary extract), RE2 (1500 ppm rosemary extract), and LE2 (1500 ppm laurel extract) groups remained below six during 8 months of storage. Volatile components of encapsulated fish oil were the highest in control, thyme and laurel extracts compared to the microcapsules with rosemary extracts in terms of total aldehyde generation. Sensory analysis showed that fresh fish odor was better preserved with rosemary extract compared to other plant extracts. It was concluded that microencapsulation of fish oil with sodium caseinate and lactose as wall material and rosemary and laurel extracts as antioxidants enhanced the oxidative stability of the microcapsules.

Abstract The random distribution model (RDM) and uniform distribution model (UDM) were used to simulate the thermal sterilization of canned fruit. The RDM was established with the radiation function, and the stability of RDM results was analyzed by simulating temperature change during thermal sterilization and determining the sterilization parameter F value of the slowest heating zone (SHZ). The performance of the distribution models in simulating thermal sterilization heating process of canned fruit with different shapes was studied using the UDM and RDM of canned yellow peach (hemispherical shell), pear (sphere), and coconut (cube). Simulation results were compared with experimental results. The flow field and temperature field distributions were used in analyzing the influence of fruits shape on the accuracy of the models. The simulation results of different RDMs were consistent with the temperature change and F value, indicating that the RDMs had stable simulation results. When the contact between two types of fruit was a point, the UDM can be used in the numerical simulation of thermal sterilization. When the contact was a non-point, the RDM was more accurate in simulating thermal sterilization. This study provides constructive suggestions for the simulation of thermal sterilization of canned fruit with different shapes.

Abstract In view of the problem that conventional insecticidal methods cannot inhibit the hatching of insect eggs in rice, microwave heating was used to kill the insect eggs hidden in the rice grains. The lethal conditions of microwave irradiation on insect pests in rice and the effects of microwave irradiation on the quality of rice were studied, and the process conditions that can both ensure the quality of rice and kill insects were put forward. The microwave energy density parameter was used to evaluate the lethal conditions of microwave irradiation for insect pests in rice. The results showed that the lethality ratio of insect pests was 100% when the microwave energy density was higher than 0.0325 kW h/kg. Both microwave power density and microwave power affected the quality of rice. The results concluded that the cracking ratio, chalkiness and amylose content were increased with the increase of microwave power at the same microwave power density, while the free fatty acid content was decreased. Through the study of variable microwave power process, it was found that the cracking ratio and chalkiness can be controlled below 1.5% when the heating rate of rice at the later stage of microwave irradiation was less than 0.2 °C/s. The use of two-stage variable microwave power process can eventually ensure the disinfestation and the quality of rice simultaneously.

Abstract Food waste is one of the major challenges in food safety and finding a solution for this issue is critically important. Herein, edible films and coatings became attractive for scientists as they can keep food from spoilage. Edible films and coatings can effectively preserve the original quality of food and extend its shelf life. Polysaccharides, including starch and cellulose derivatives, chitosan, alginate and pectin, have been extensively studied as biopackaging materials. One of the most interesting polysaccharides is alginate, which has been used to make edible films and coatings. Incorporating essential oils (EO) in alginate matrices results in an improvement in some properties of the edible packages, such as antioxidant and antimicrobial properties. Additionally, the use of nanotechnology can improve the desirable properties of edible films and coatings. In this article we reviewed the antimicrobial and antioxidant properties of alginate coatings and films and their use in various food products.

Abstract This study aimed to investigate effects of ellagic acid (EA) and ε-polylysine hydrochloride (ε-PL) on biogenic amines (BAs), volatile compounds and quality of salmon slices stored at 4 °C. The results showed that EA and ε-PL attenuated the production of BAs, retarded the increase of TVC, TVB-N and TBARS. Additionally, water mobility, texture properties of salmon slices were also stabilized by the EA and ε-PL. Volatile compounds including aldehydes, alcohols and hydrocarbons were identified and spoilage-related compounds reduced by the EA and ε-PL, which was related to the inhibition of bacterial, TVB-N and TBA growth by EA and ε-PL. The content of phencthylamine, putrescine, cadaverine, histamine and tyramine in EA-s-PL groups reduced by 46.53%, 54.1%, 26.42%, 31.98% and 45.37% compared to the control group at the end of storage, respectively. Therefore, EA and ε-PL can be applied for inhibiting the increase of BAs and delaying quality deterioration of salmon slices.

Abstract Cupcakes were made by LZ-111 and LS-10 raw dehydrated potato flour (RDPF) with 10 %, 30 %, and 50 % additions. The addition of RDPFs improved nutritional quality but decreased the height and lightness compared to the control. Supplementation of RDPFs increased the hardness while decreased the adhesiveness and springiness. The sensory evaluation results showed that the score gradually decreased with the increase of RDPFs addition. Thermomechanical properties demonstrated that the gluten strength and the viscosity of the mixed dough were decreased while the water absorption rate was increased. The incorporation of RDPFs revealed a significant increase in volatile aroma compounds and LS-10 contributed more compounds than LZ-111. Isovaleraldehyde (no. 6), hexanal (no. 11) and 1-nonanol (no. 23) were considered to give the highest sensory evaluation scores in odor to the control cupcakes. Tetrachloroethylene (no. 45) and hexafluoro-1,1,3,4-tetrachlorobutane (no. 54) may be the pivotal volatiles caused bad odor in LS-10 RDPF cupcakes.

Abstract Chestnut starch acetates (CSA) with different degrees of substitution (DS) were prepared. The structure and physicochemical properties of CSA were then determined, with scanning electron microscopy showing that most of the CSA granules were damaged and dented, and adhered with increased in DS. X-ray diffraction results indicated that the crystal form of CS and CSA was type C. Chemical structure analysis showed that the starch molecule was grafted with acetyl groups. The transparency, freeze–thaw stability, solubility and swelling power of CSA improved with an increase in DS. The viscosity and stability of CSA were significantly improved and pasting temperatures reduced compared with native CS. The cohesion, hardness, gumminess, chewiness and springiness of CSA decreased with an increase in DS, whereas adhesiveness increased. By comparing the properties of CSA with different DS, a new option was provided for the application of renewable natural polymer CSA in food fields.
