Effects of Milling Methods on Rice Flour Properties and Rice Product Quality:A Review

High-quality rice flour is the foundation for the production of various rice-based products.Milling is an essential step in obtaining rice flour,during which significant changes occur in the physicochemical and quality characteristics of the flour.Although rice flour obtained through mainstream wet milling methods exhibits superior quality,low production efficiency and wastewater discharge limit the development of the industry.Dry milling,on the other hand,conserves water resources,but adversely affects flour performance due to excessive heat generation.As an emerging powder-making technique,semi-dry milling offers a promising solution by enhancing flour quality and reducing environmental impact.This is achieved by minimizing soaking time through hot air treatment while reducing mechanical energy consumption to reach saturated water absorption levels.However,continuous production remains a challenge.This comprehensive review summarizes the effects of various milling technologies on rice flour properties and product qualities.It also discusses key control indicators and technical considerations for rice flour processing equipment and processes.

Product quality prediction based on RBF optimized by firefly algorithm

With the development of information technology,a large number of product quality data in the entire manufacturing process is accumulated,but it is not explored and used effectively.The traditional product quality prediction models have many disadvantages,such as high complexity and low accuracy.To overcome the above problems,we propose an optimized data equalization method to pre-process dataset and design a simple but effective product quality prediction model:radial basis function model optimized by the firefly algorithm with Levy flight mechanism(RBFFALM).First,the new data equalization method is introduced to pre-process the dataset,which reduces the dimension of the data,removes redundant features,and improves the data distribution.Then the RBFFALFM is used to predict product quality.Comprehensive expe riments conducted on real-world product quality datasets validate that the new model RBFFALFM combining with the new data pre-processing method outperforms other previous me thods on predicting product quality.

International Patent Cooperation,Patent Prosecution Highway Agreements,and Export Product Quality

This paper investigates how international cooperation for patent examination using Patent Prosecution Highway(PPH)agreements has affected the quality of firms'exports.Taking the PPH agreements signed between China and the export destinations as a quasi-natural experiment,we established a difference-in-difference-in-differences model.We found that international cooperation for patent examination caused firms to increase export quality to PPH partners in patent-intensive industries to a greater extent.This effect was more profound among PPH partners with stronger intellectual property protection,diferentiated products and core products,and agreements along with the Patent Cooperation Treaty.We also found that PPH agreements increased the number of Chinese patent applications filed in PPH partners,patent applications by PPH partners in China,and the level of innovation,all of which constitute the major channels through which export quality to PPH partners increases.Our findings demonstrate that international patent cooperation has played an important role in promoting international trade quality.

Product Quality Evaluation Method Based on Product Gene Theory

Traditional quality inspection based product quality evaluation method with complex process has high operating cost and requires more professional knowledge. To remove the above limitation, this paper leads product gene theory into product quality evaluation. Methods of quality influencing factors based modeling and encoding are established. Combined with similarity theory and product gene theory, a product gene similarity analysis based quality evaluation method is proposed. The proposed method is low cost, operates easily and requires less specialized knowledge. A case study is conducted to prove the correctness and feasibility of this method.

Assessing the product quality and biological activities of barley(Hordeum vulgare L.)grasses at different harvest times

Barley(Hordeum vulgare L.)grasses(BG)have attracted considerable interest due to their multiple physiological activities and health benefits.In this paper,eight BG at four different growth stages were collected:seedling,tillering,stem elongation,and heading,and their product qualities and biological activities were examined and studied.Results demonstrated that harvest time obviously influenced proximate composition,surface color,and amino acid profile.Z21 and Z23 harvested at the seedling and early tillering stages,respectively,had higher total phenolic content(TPC)and total flavonoid content(TFC)than the other BG.Moreover,Z21 and Z23 possessed better DPPH radical-scavenging ability,antioxidant capacity,andα-glucosidase inhibitory activity,which were positively correlated with TPC,TFC,and protein and total amino acid contents.Our findings suggested that the early tillering stages were the preferable harvest times for BG with good product quality and biological properties.

Analysis of the influence of the hot-rolling material on galvanized product

Hot-rolled galvanized steel sheet is made from hot-rolled pickled sheet by continuous hot-dip galvanizing process.Without the cold-rolling process,it greatly reduces the operating costs and saves investment for shorter process and lower energy consumption.The economic advantage is obvious.The characteristics of high-yield and low cost will greatly enhance the competitiveness of enterprises in the market.There are big differences between the substrates of hot-rolled galvanized steel sheet and cold-rolled galvanized steel sheet in surface roughness,chemical elements,and surface defects.These factors directly affect on the quality of galvanized sheet.Pickling process is used to remove the oxide layer which is formed on the surfaces of hot-rolled steel sheet.The surfaces must be thoroughly cleaned for the oxide layer will seriously affect the adhesion of galvanized coating.Residual impurities,Carbon concentrating and other problems must not be caused during pickling as well.Therefore,the quality of galvanizing depends on the quality of pickled sheet surfaces.Experimental methods such as AES,XPS,SEM,OM are employed during the research for detailed analysis on the effects of hot-rolled plates and hot pickling plates on the quality of hot-rolled galvanized products.

Assessing the Awareness and Usage of Quality Control Tools with Emphasis to Statistical Process Control (SPC) in Ethiopian Manufacturing Industries

Introduction: The present work was devoted to assess the awareness and usage of quality control tools with the emphasis on statistical process control in Ethiopian manufacturing industries. Semi structured questionnaire has been employed to executive and technical managers of manufacturing industries of various size and specialism across the country. Stratified random sample method by region was used to select sample industries for the study. The samples used for this study are industries mainly from Oromiya, Addis Ababa, Tigray, Amara, SNNP and Diredawa regions proportional to their size of the available industries. Methods: Exploratory method and descriptive statistics was used for data analysis. Available documents and reports related to quality control policy of the selected companies were investigated. Results and Discussions: The number of manufacturing industries involved in this study was 44. Of the sampled manufacturing industries about 60% are from Oromiya and Addis Ababa regions. It has been reported that 100% of the respondents said that the importance of quality control tools is very important to their organizations’ productivity and quality improvement (Figure 3). Quality control professionals were also asked the extent to which quality control system is working in their industry and majority of the respondents (45%) have indicated that quality control system is working to some extent in their respective industries (Figure 18). Conclusions and Recommendations: Most of the quality department of the industries did not fully recognize the importance of statistical process control as quality control tools. This is mainly due to lack of awareness and motivation of the top managements, shortage of man power in the area, and others together would make it difficult to apply quality control tools in their organization. In general, the industries in Ethiopia are deficient in vigor and found to be stagnant hence less exposed to a highly competitive market and don’t adopt the latest quality control techniques in order to gain knowledge about systems to improve quality and operational performance. We conclude that quality management system has to be established as an independent entity with a real power and hence the quality control department which is responsible for quality can make an irreversible decision with respect to quality of any given product. Moreover, the concerned bodies (government and ministry of industries) should give attention and work together with universities to ensure how these statistical process control techniques could be incorporated in a curriculum of the universities at higher levels in degree and masters programs. Furthermore, different trainings which could improve quality and efficiency of their respective management system should be given as short and long term to the employees including top and middle managers found in various industries relevant to their process.

Production quality and pricing strategy for substitutable products under comparison effects

Comparison effects have been studied extensively in many fields.In particular,existing operations management articles have discussed the impact of comparison effects on enterprises'production and pricing decisions.Research has also shown that consumers'purchasing decisions are primarily determined by three factors:product quality,selling price,and comparison effects.The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist's production quality and pricing strategy for substitutable products.Results reveal the following:(1)Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model.(2)The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices.(3)When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products,the monopolist's optimal choice in the second stage is to keep production quality constant and increase the selling price.Consequently,the number of buyers does not decrease because of temporal comparison effects.Therefore,the firm increases its revenue.(4)For the market with two substitutable products with quality differences,one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period.At this point,the consumption situation in the market is the same as that in the first stage.Therefore,when no external constraints exist,the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage.(5)When consumer identity information can be confirmed in the market,social comparison effects,similar to temporal comparison effects,could help the enterprise increase its price and profit while maintaining product quality.These social and temporal comparison effects constrain consumers.Thus,the number of people who continueto buyproducts does not decrease.

Potential use of garlic products in ruminant feeding:A review

The addition of antibiotics as growth promoters to ruminant feed can result in bacterial resistance and antibiotic residues in ruminant products.Correspondingly,there is serious public concern regarding the presence of antibiotic residue in ruminant products and the consequent threat to human health.As a result,the addition of plants and their products to ruminant feeds,as an alternative to antibiotics,has received much attention recently.Garlic and its products are rich in organosulphur compounds,which have a variety of biological activities and have been widely used as natural additives in animal production.This review presents recent knowledge on the addition of garlic products(powder,skin,oil,leaf and extracts)to the diets of ruminants.In this paper,garlic products are evaluated with respect to their chemical composition,bioactive compounds,and their impacts on the rumen ecosystem,antioxidant status,immune response,parasitic infection,growth performance and product quality of ruminants.This review provides valuable guidance and a theoretical basis for the development of garlic products as green,highly efficient and safe additives,with the aims of promoting ruminant growth and health,reducing methane emissions and improving ruminant product quality.Garlic extracts have the potential to control parasite infections by decreasing the faecal egg count.Garlic powder,oil and allicin are able to reduce the methane emissions of ruminants.Organosulphur compounds such as allicin,which is present in garlic products,have the potential to inhibit membrane lipid synthesis of the archaeal community,thus influencing the population of methanogenic archaea and resulting in a reduction in methane emissions.Some garlic products are also able to increase the average daily gain(garlic skin,water extract,and leaf)and the feed conversion ratio(garlic skin and leaf)of ruminants.Garlic stalk silage fed to sheep has the potential to improve the nutritional value of mutton by increasing the concentrations of linoleic and linolenic acids and essential amino acids.Sheep fed a diet containing garlic powder or oil are able to produce milk with higher concentrations of the conjugated linoleic acids and n-3 fatty acids,which has health benefits for consumers,due to the widely recognized positive impact of n-3 polyunsaturated fatty acids and conjugated linoleic acids on human heart health,improving platelet aggregation,vasodilation and thrombotic tendency.Overall,garlic products have the potential to enhance growth performance and product quality and reduce parasite infections,as well as methane emissions of ruminants.
