According to the latest BMI American petrochemical industry report, the current U.S. recovering petrochemical industry, but the relatively slow speed recovery, want to 2013 to restore to the level in 2008, in the long run, suffer from Asia and the Middle East competition intensifies, American petrochemical production capacity will be suppressed.
2009 major U.S. plastic resin product output for 3620 tons, small increase in 2008 than 0.9 percent. One low density polyethylene (LDPE) sales fell to 306 million tons; 5.7% The polystyrene (PS) sales fell 2 245 million tons, Polypropylene (PP) 2.8% year-on-year drop to 7.6 million tons, Polyvinyl chloride (PVC) output fell 1.3-580 million tons, And LLDPE and HDPE yield year-on-year growth rates rose 4.2 per cent and 1.1 million tons and 772 tons.
BMI, American petrochemical products output growth, but until 2011 and 9% in 2012 will slow rebound.

The traditional consumer habits affect, plus the speed, the pace of life in food, Chinese people still with frozen pasta, especially such consumption dumplings.

However, the dumpling cracking, dehydrate, leather Browning serious impact on the quality of products, to consumer, less a delicious, to the enterprise, but lost part of the market.

Say it has become one of the important quick-frozen dumpling. In order to change this situation, the enhancement enterprise competitiveness, improve the quality of our quick-frozen dumpling, not changing the quick-frozen process conditions, by adding food additives to improve PiPin dumplings with purpose.

Experimental materials and equipment

Special frozen dumpling flour: a. dumpling flour improvers b. c. thickening agent of reinforcement as gel d. dumpling flour improvers B + thickening agent of reinforced C (1:2), dumpling improver B + times (2:3 gel D thickening agent, flour) reinforced C + times (2:3 gel D), dumpling flour improvers B + thickening agent of reinforced C + times gel D (3:4:6). Mixer, cutting roller machine, double helix face powder, quick-frozen device, tension tester, refrigerated, cold storage.

Experimental methods

Mix flour with is 100 gold after the additive and determine the dosage of water, use and silty tensile test data for processing after the flour quality evaluation.

According to the different proportion of different additives with food additive, in accordance with the conditions were adding flour into 100kg, stir all 48kg water, rolling and kneading make dough smooth, time setting for 10min. Then use rolling machine, bag making, rolled into frozen tunnel - 38 degrees Celsius, 25min frozen and blank control without additives (A).

With the different proportion of dose with additives, frozen dough bag of flour with single and please experienced technical personnel 10 assessment team of dumpling appearance, color, fry, craze, etc, and sensory evaluation data, each group of extracting 1000 dumplings for inspection.

Each group of 20, dumpling arbitrary by quick-frozen dumpling use cooking and strict control of cooking, cooking 15min (guarantee cooked). Organize professional product test and taste, personnel, boiled dumpling accreditation JiaoZiPi whether bubbles and bubbly after severe, taste additives for dumpling skin texture is chewing and influence of conclusion, smoothness on record.

For each group of dumplings, 1000 Celsius conditions for storage in three months, each month on its technical personnel organization random samples for testing, in the process of recording stored water dumpling and cracking.

Results and analysis of flour, adding different additives in opaque and drawing on the determination of gluten content changes. Experimental results show that the use of additives in formation gluten flour, stable rise time declined, Weakening degree, reduce anti-spasticity enhanced obviously strengthened, ductility, this may be due to the different quality of additives.

The dough in rolling and kneading, leather bag, evaluation system, personnel with professional knowledge and experience of perennial comprehensive evaluation, mainly through the surface and the kumite out dough and handle, face the dough stuck when skin and package system and adhesion between the face. In the dough forms and the dough rolled into the flour, the network will void formation gluten free water, bind tightly to the dough and face no water, not glue the hand, keep smooth. According to the use of food additives in the national standard, allowing selection within the scope of use of flour for the test. Test results show that: in the same doses, different additives on the smoothness of the dough, hold water, viscosity, use additives, more performance improved obviously.

The skin moisture content of dumpling appearance, color, fry, the effect is an important reason for the cracks in the skin: because, after the network forming gluten free water in - 30 degrees below, quick-frozen form small ice, and make the face of fixed deformation, water molecules to flour of amylopectin stripping adhesion strength, strengthen between molecules anti-cracking performance enhancement, moisture loss not easily after frozen water activity, to reduce biomaterial dough oxidation Browning. The effect is not obvious in shape, the color white degree of blank test is a bit poor, fry line in the aspects of C + + D quantity, at least for B + C + + D number at least. In the control of crack and fry flour, the number of lines in a suitable additive is C, C + + D and B C + D.

Dumpling from thawing to cook, is actually colloid by elastic to liquid from homomorphisms, gluten network with changes in temperature, FenZiLi reduce between the structure and easy damaged. Lax, In cooked dumpling, strict process of cooking time and temperature control, avoid cooked on the palate, cooked test results show that adding additives in reducing the dumplings, transparent, enhance bubbles appeared in the universal female advantage, especially C and E skin to have a fundamental breakthrough dumpling, make skin quality have large dumpling of ascension.

The experiment in storage (mainly through 30 degrees Celsius) - fluid, craze of dumpling skin to explain the retention performance additives, experimental results show: two months before the loss is not obvious, the last month, have obvious skin moisture ability of additive dumplings are ascending, B best effect. From the experiment results, dumpling cracking dehydrate, number of skin, but with time and increase the basic, so as to prove in storage process, control temperature fluctuations, cold consumption, ice is problem solving factors such as the sublimation of the method is more effective.

Conclusion through the five additives used alone comparative tests showed that use additives for quick-frozen dumpling skin moisture, crack, color, smooth muscle, etc. Have better effect, so as to prove the additives in quick-frozen dumpling role and status. Additive and make changes in the flour dumpling deficiencies, improve the quality of flour for the dough, providing better plasticity, effectively resolve the dough in frozen storage, transportation, sale all sorts of problems appeared in the process, greatly reduce the cost and improve the quality of the dumplings, and enhance its competitiveness, and promote the frozen food industry, food additives in the application.

March 1986 America first launched “clean coal technology demonstration project”, the main (CCTP) contains four aspects: (1) advanced coal-fired power technology (integrated gasification combined cycle power - IGCC fluidbed burning, and improve combustion CFBC - and direct coal gas), (2) environmental protection equipment (control); and the SOx NOX (3) coal into a clean energy technology (washing, mild gasification, liquefaction), (4) industrial application (iron, cement and other industry control sulphur, nitrogen, dust and gas emissions recycling cleaning, etc.). Thirteen of commercialization achieved initial results. European countries are developing the project have gasification combined cycle power (IGCC), coal and biomass gasification (or combination and waste combustion), circulating fluidized bed combustion, solid fuel aerification and fuel cell technology, combined cycle. Japan in recent years is greatly increased began coal consumption, the development of clean coal technology.

Market participants said recently, if ethylene prices continue to adjust, the second half of this year the naphtha cracking operators in Asia may be cut device starts.

According to reports, ICIS prices are increasing supply from the Middle East, and stock higher ethylene Asia week prices down to seven months lows, drop to $1000 per ton 930 ~ (CFR, northeast Asia). This year, Japan has 8 sets of ethylene cracking unit overhaul plan, is expected to cease before the end of August. In Asia, there was only Asri company plan Chandra operators device Cilegon located in July to 60 tons/year device starts to 80%, June approximately 90% starts.

In the first half of this year is more than $400 gross ethylene/ton stimulation, Asian naphtha cracking unit starts in general maintenance of 90% to 100%. But since may also up the price of ethylene write-dow has affected the ethylene Maori level. Shanghai China olefin traders think that a future market environment will become more difficult, in Europe the debt crisis of the Chinese government tightening credit worries and scale of consumer demand, which would influence in petrochemical industry.

China petroleum enterprise association, said HuWenRui 18 unconventional natural gas resources in China is speeding up the development of dense gas has entered, scale development phase, the coalbed methane, shale gas utilization of natural gas hydrate is started, the research also strengthened gradually, in some areas has formed with the world’s advanced level of technology.

HuWenRui held in the 2nd China petroleum and petrochemical industry, China international BBS said unconventional natural gas resources is the amount of conventional gas 5.01 times. At present, China petroleum enterprise has initially formed unconventional natural gas resources exploration and development of the theory, technology and management experience and countermeasures, mode, and cooperate with international oil companies, in the density of gas development unconventional natural gas field has been developed with the world’s advanced level of technology.

Unconventional natural gas resources is not fully known, to not to mature technology and experience of the development of gas resources. Mainly include methane gas, dense, shale, gas hydrate etc. Relative to conventional gas resources, unconventional natural gas reserves, but the development more difficult.

HuWenRui said, when oil prices are stable in 60-80 dollars a barrel, unconventional natural gas resources between into conventional resource development has the economic feasibility. But the large-scale development in body remains to be mature and developed technology development way realization scale, intensive.

Global unconventional natural gas resources are very rich. The authorities estimate about unconventional natural gas resources of conventional gas resources, the conventional 4.56 times of oil and gas resources, including 1.65 proportion of natural gas hydrate.

“High carbon energy using the concept of” low carbonization since this year, make domestic large coal enterprise into a new upsurge of chemical industry has more sufficient reasons.
