The role of food safety has developed significantly in the last 2 decades, so today the production and processing of safe and quality food is of primary importance. Modem food production is based on principles of GAP and GMP （including GHP） and different methods and tools for quality control and assurance （IFS, HACCP, ISO-9000, ISO-9000/2010, ISO-22000, TQM）. There are different techniques and methods to produce safe food and to control the quality of the foodstuffs. The modem, up-to-date technologies and measurement techniques involve the application of many physical methods - high pressure, pulsing electrical field, microwave, non-destructive techniques （e.g., INAA, NMR, NIR-NIT, PAS）, radiation treatments as well. Using radiation technologies （of course not only nuclear ones） it is possible to fulfil some very important expectations of modem food processing, e.g., decrease of microbial contamination, improvement of sensory properties, increase of storability of food products.展开更多

Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical content.Compared to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.展开更多

The results showed that the polarization cross of lotus-seed starch granules was weakening gradually with increasing the treatment time, which indicated the termination of their ordered crystallite structures. The morphologies of granules were collapsed once the UHP was kept at 500 MPa for 60 minutes. The particle size analysis demonstrated that the granule size and distribution of lotus-seed starches increased as the treatment time was prolonged. X-ray diffraction studies showed that the intensity of the feature diffraction peaks of starch decreased and eventually disappeared with increasing the treatment time, and B-type transformation pattern was observed. The Fourier transform infrared spectra （FTIR） analysis of starch showed that the UHP is a physical modification processing because no new groups formed. The research showed that UHP processing at certain degree is capable to achieve the modification of lotus-seed starch. It is of significance for the deep processing of lotus-seed products.展开更多

The process excluded the use of a synthetic carrier polymer or non-aqueous solvents thus maintaining the food-grade status of the components. The inclusion of PUL reduced the surface tension and electric conductivity of pectin solution, and promoted molecular entanglement between PEC and PUL as confirmed by rheological analysis. The spinnability of either polysaccharide was promoted by inclusion of the other. Cross-linking PEC networks were obtained by soaking the fibrous mats in successive Ca<sup>2+</sup> solution. The fibrous mats can be used to carry bioactive compounds as demonstrated using probiotic bacteria Lactobacillus rhamnosus GG (LGG) as a model bioactive compound. The research is significant for the development of food products with unique textures and functionalities.展开更多

Food production and processing of quality food and safe food are today of primary importance. Food production is based on the principles of Good Agricultural Practice （GAP）, Good Manufactoring Practice （GMP） and Good Hygiene Practice （GHP）. Recently, the industrial food processing is focused dominantly on the quality, and one of the basic requirements of the quality is the safety. There are different methods and techniques to produce safe food. The up-to-date food technologies and quality measurements （quality control and quality assurance） involve the application of different physical methods, e.g., high pressure, pulsing electrical field, nondestructive techniques, e.g., nuclear magnetic resonance （NMR）, near infrared reflectance, near infrared transmittance （NIR-NIT）, photo acoustic spectroscopy （PAS） and instrumental neutron activation analysis （INAA） for chemical composition determination, radiation techniques, nanofiltration and reverse osmosis （RO） as well. Using ionizing radiation （nuclear methods） and non-ionizing radiation technologies, it is possible to fulfill a lot of expectations： decrease of microbial contamination, improve of sensory properties, increase of storability, etc..展开更多

This study was conducted to evaluate the effect of different processed food commonly consumed in Maroua (Far North Region, Cameroon) on the Glycemic Index (GI). To ameliorate the follow up of MS and population’s nutrition education, a survey was conducted among 200 families. The ten most consumed meals were selected after a food survey among 200 families. The meals were mostly made of a vegetable soup associated to a high carbohydrate staple. Vegetables and cereals were processed according to the food survey results. Then, a food tolerance test was performed on 30 male volunteers living in the same region. Among them, 12 were selected with an average age of 28.25 and a mean BMI of 19.63. They were studied on separate occasions in the morning after an overnight fast. After fasting, blood glucose was taken before and (15, 30, 45, 60, 90 and 120 minutes) after eating a test meal compared to sucrose and glucose solution (33.33%) used as reference. Glycemic response curves were used to calculate the gi of each meal. Results show that GI of the tested meals varied significantly (p < 0.05) between 20 and 79. Red millet porridge with kelenkelen-beans (Cochorus oletorius-Vigna unguiculata) sauce and red millet porridge with kelenkelen-peanut (Cochorus oletorius-Arachis hypogea) sauce exhibited the lowest GI. The highest GI was observed in corn porridge associated with fresh okra (Hibuscus esculentus) or with tasba (Cassia tora)-okra-beans sauce.展开更多

文摘The rate of flavor release in the mouth from traditional dry-cured pork was evaluated in this study.It was hypothesized that a slow steady release of flavor would occur on chewing and hydration.To test this,high salt dry-cured pork was chewed and held in oral cavity without swallowing for 4 different chewing stages(B,NC_(30),C_(30),EC).Saliva and food bolus from 16 healthy subjects were collected during oral processing,and analyzed for saliva flow rate,total saliva protein content,saliva pH,conductivity,saliva and sodium,and taste components.Results show that oral processing behavior and salivary release have important effects on flavor release of dry-cured pork.Sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)analysis showed that oral processing has a certain effect on the protein composition and concentration in saliva.This study suggests that the interaction between food and saliva that accompanies chewing can lead to significant changes in sensory perception during oral processing.

文摘In this paper, the time dependent effects of various pressure treatments on the characteristics of lotus-seed starch which was modified by ultra-high pressure （UHP） were investigated. The results showed that the polarization cross of lotus-seed starch granules was weakening gradually with increasing the treatment time, which indicated the termination of their ordered crystallite structures. The morphologies of granules were collapsed once the UHP was kept at 500 MPa for 60 minutes. The particle size analysis demonstrated that the granule size and distribution of lotus-seed starches increased as the treatment time was prolonged. X-ray diffraction studies showed that the intensity of the feature diffraction peaks of starch decreased and eventually disappeared with increasing the treatment time, and B-type transformation pattern was observed. The Fourier transform infrared spectra （FTIR） analysis of starch showed that the UHP is a physical modification processing because no new groups formed. The research showed that UHP processing at certain degree is capable to achieve the modification of lotus-seed starch. It is of significance for the deep processing of lotus-seed products.

文摘Animal-derived protein production is one of the major traditional protein supply methods,which continues to face increasing challenges to satisfy global needs due to population growth,augmented individual protein consumption,and aggravated environmental pollution.Thus,ensuring a sustainable protein source is a considerable challenge.The emergence and development of food synthetic biology has enabled the establishment of cell factories that effectively synthesize proteins,which is an important way to solve the protein supply problem.This review aims to discuss the existing problems of traditional protein supply and to elucidate the feasibility of synthetic biology in the process of protein synthesis.Moreover,using artificial bioengineered milk and artificial bioengineered eggs as examples,the progress of food protein supply transition based on synthetic biology has been systematically summarized.Additionally,the future of food synthetic biology as a potential source of protein has been also discussed.By strengthening and innovating the application of food synthetic biology technologies,including genetic engineering and high-throughput screening methods,the current limitations of artificial foods for protein synthesis and production should be addressed.Therefore,the development and industrial production of new food resources should be explored to ensure safe,high-quality,and sustainable global protein supply.
文摘Electrospinning was used to produce ultrafine fibers and fibrous mats from aqueous solutions containing two edible polysaccharides: pectin (PEC) and pullulan (PUL). The process excluded the use of a synthetic carrier polymer or non-aqueous solvents thus maintaining the food-grade status of the components. The inclusion of PUL reduced the surface tension and electric conductivity of pectin solution, and promoted molecular entanglement between PEC and PUL as confirmed by rheological analysis. The spinnability of either polysaccharide was promoted by inclusion of the other. Cross-linking PEC networks were obtained by soaking the fibrous mats in successive Ca<sup>2+</sup> solution. The fibrous mats can be used to carry bioactive compounds as demonstrated using probiotic bacteria Lactobacillus rhamnosus GG (LGG) as a model bioactive compound. The research is significant for the development of food products with unique textures and functionalities.
文摘The paper deals with some questions of important aspects of food safety and application of principles of food physics in the food sector. Food production and processing of quality food and safe food are today of primary importance. Food production is based on the principles of Good Agricultural Practice （GAP）, Good Manufactoring Practice （GMP） and Good Hygiene Practice （GHP）. Recently, the industrial food processing is focused dominantly on the quality, and one of the basic requirements of the quality is the safety. There are different methods and techniques to produce safe food. The up-to-date food technologies and quality measurements （quality control and quality assurance） involve the application of different physical methods, e.g., high pressure, pulsing electrical field, nondestructive techniques, e.g., nuclear magnetic resonance （NMR）, near infrared reflectance, near infrared transmittance （NIR-NIT）, photo acoustic spectroscopy （PAS） and instrumental neutron activation analysis （INAA） for chemical composition determination, radiation techniques, nanofiltration and reverse osmosis （RO） as well. Using ionizing radiation （nuclear methods） and non-ionizing radiation technologies, it is possible to fulfill a lot of expectations： decrease of microbial contamination, improve of sensory properties, increase of storability, etc..
文摘As deep learning techniques are increasingly applied with greater depth and sophistication in the food industry,the realm of food image processing has progressively emerged as a central focus of research interest.This work provides an overview of key practices in food image processing techniques,detailing common processing tasks including classification,recognition,detection,segmentation,and image retrieval,as well as outlining metrics for evaluating task performance and thoroughly examining existing food image datasets,along with specialized food-related datasets.In terms of methodology,this work offers insight into the evolution of food image processing,tracing its development from traditional methods extracting low and intermediate-level features to advanced deep learning techniques for high-level feature extraction,along with some synergistic fusion of these approaches.It is believed that these methods will play a significant role in practical application scenarios such as self-checkout systems,dietary health management,intelligent food service,disease etiology tracing,chronic disease management,and food safety monitoring.However,due to the complex content and various types of distortions in food images,further improvements in related methods are needed to meet the requirements of practical applications in the future.It is believed that this study can help researchers to further understand the research in the field of food imaging and provide some contribution to the advancement of research in this field.

文摘Plant-based meat analogues(PBMA)are formulated to mimic the sensory characteristics of traditional meat products(TMP)using vegetarian ingredients and are increasingly popular with the trend towards plantbased diets,even among meat-eating consumers.This narrative review compared the nutritional quality of PBMA and TMP to broaden the discussion on the suitability of simulated meat products to substitute TMP,while exploring other attributes for their comparison.The complexity of PBMA and TMP means they are not entirely interchangeable.Importantly,PBMA health effects extend beyond their basic nutrient content and quality.Postprandial metabolism and satiety,for example,can be affected by product formulation,ingredient interactions,and thermomechanical processing involved in producing organoleptically acceptable PBMA.There are specific opportunities for low-sodium PBMA products to contribute to a healthy shift toward plantbased diets.In conclusion,PBMA cannot be assumed to be healthier than TMP.They should be designed with comprehensive consideration of composition and processing to ensure they support consumers who are adopting plant-based diets in realizing the theoretical health benefits.

文摘High-saturated fat(HF)or high-fructose(HFr)consumption in children predispose them to metabolic syndrome(MetS).In rodent models of MetS,diets containing individually HF or HFr lead to a variable degree of MetS.Nevertheless,simultaneous intake of HF plus HFr have synergistic effects,worsening MetS outcomes.In children,the effects of HF or HFr intake usually have been addressed individually.Therefore,we have reviewed the outcomes of HF or HFr diets in children,and we compare them with the effects reported in rodents.In humans,HFr intake causes increased lipogenesis,hypertriglyceridemia,obesity and insulin resistance.On the other hand,HF diets promote low grade-inflammation,obesity,insulin resistance.Despite the deleterious effects of simultaneous HF plus HFr intake on MetS development in rodents,there is little information about the combined effects of HF plus HFr intake in children.The aim of this review is to warn about this issue,as individually addressing the effects produced by HF or HFr may underestimate the severity of the outcomes of Western diet intake in the pediatric population.We consider that this is an alarming issue that needs to be assessed,as the simultaneous intake of HF plus HFr is common on fast food menus.
文摘Metabolic Syndrome (MS) has reached a pandemic proportion and has an impact on the incidence and severity of cardiovascular pathologies. This study was conducted to evaluate the effect of different processed food commonly consumed in Maroua (Far North Region, Cameroon) on the Glycemic Index (GI). To ameliorate the follow up of MS and population’s nutrition education, a survey was conducted among 200 families. The ten most consumed meals were selected after a food survey among 200 families. The meals were mostly made of a vegetable soup associated to a high carbohydrate staple. Vegetables and cereals were processed according to the food survey results. Then, a food tolerance test was performed on 30 male volunteers living in the same region. Among them, 12 were selected with an average age of 28.25 and a mean BMI of 19.63. They were studied on separate occasions in the morning after an overnight fast. After fasting, blood glucose was taken before and (15, 30, 45, 60, 90 and 120 minutes) after eating a test meal compared to sucrose and glucose solution (33.33%) used as reference. Glycemic response curves were used to calculate the gi of each meal. Results show that GI of the tested meals varied significantly (p < 0.05) between 20 and 79. Red millet porridge with kelenkelen-beans (Cochorus oletorius-Vigna unguiculata) sauce and red millet porridge with kelenkelen-peanut (Cochorus oletorius-Arachis hypogea) sauce exhibited the lowest GI. The highest GI was observed in corn porridge associated with fresh okra (Hibuscus esculentus) or with tasba (Cassia tora)-okra-beans sauce.
文摘<span style="font-family:;" "=""><strong>Introduction</strong><strong>:</strong></span><span style="font-family:;" "=""> Facing the challenge of increasing consumption of processed foods in China, along with the demand for salt reduction, and dynamic adjustment of universal salt iodization (USI) policy, it is necessary to timely evaluate the distribution of iodine content in processed foods and condiments, so as to provide more accurate data for population dietary iodine intake assessment. <b>Methods:</b> From markets in 6 cities and e-commerce platforms, cereal, tuber, le</span><span style="font-family:;" "="">gume, meat, fish, egg, and dairy products, and condiments, consumed by volunteers who attended in iodine intake investigation, and top selling products in particular with well-noted brands were preferentially sampled during 2017 t<span>o 2019. After being mixed and homogenized, each sample was detected by ICP-MS method. The range and medium of iodine content in each type of product were given. <b>Results:</b> After merging samples with close value in the same style of the same brand, and screening out samples with no added salt or low sodium content (≤120 mg/100g), total 725 data were sub-grouped and analyzed. In comparison with the 95<sup>th</sup> percentile of the iodine distribution in relative nature source, assessed by our previous study, nearly 77% of products made from grains, potatoes, beans, nuts, livestock and poultry meat were presumed to be processed with iodized salt. In somewhat, related with sodium value marked on food labeling, the median iodine ranged from 1.1 mg/100g to 149 mg/100g. The variation of iodine in egg, milk and fish made products, and seaweed or with seaweed products was greatly affected by the background of ingredients, the median content most floated between 12.8 mg/100g and 86.8 mg/100g, even up to 1800 mg/100g in seasoned seaweed. Based on the frequency of iodine digital and the ratio of iodine to sodium, it was speculated that nearly 90% of soy sauce and 73.5% of other seasonings like vinegar, sauce, paste, etc., were not added iodized salt, with overall median iodine 4.0 mg/100g an</span><span>d 12 mg/100g respectively. <b>Conclusion:</b> Using iodized salt in processed foo</span><span>ds is an approach of USI police. Affected by the nature backgrounds of ingredients composed, the amount of salt used, and the regulated fortification level, iodine content in each kind of product varied largely. It’s important to establish a monitoring system in processed foods, as well as fortification salt, to control the b</span>enefit and risk of iodine health.</span>
