HIGH QUALITY WHEATS

“Processing quality of Chinese wheats needs improvement”

We have the solution for higher quality:

Since 1995 cultivar DIVANA has been the best bread making wheat in Croatia (perhaps even in Europe).

Experimental bread baking of cv. DIVANA compared with standard wheat cv. SIROKA

The cross-section of bread loaf made from the same amount of flour of standard quality cv. Siroka (left) and excellent quality cv. DIVANA (right). Bread yield for cv. Siroka is 148 g/100 g, and for cv. DIVANA 162 g/100 g of flour.

Flour made from cv. DIVANA is recommended for improvement of other poor flours in process of bread making due to its extraordinary quality.

Recent researches pointed on low Cd accumulation in grain of cv. DIVANA. Low-Cd cultivars can be grown on Cd contaminated soil as a tool to reduce the risk of toxic metal movement into human diet.

 

Rheological parameters of excelent quality cultivar DIVANA…

Farinogram_1Farinogram: after 15 min of dough development, there is no recorded softening.
Extensogram_1Extensogram: large energy (cm2) and ideal relationship between dought extensibility (mm) and resistance (EU)
Amylogram_1Amylogram: value 760 AU indicate ideal amylolitic activity. Bread will not be sticky nor going to dry quickly.

…compared to the parameters of standard cultivar SIROKA

Farinogram_2Farinogram: after 15 min dough softening (125 FU) is expressed.
Extensogram_2Extensogram: dough energy, extensibility and resistance are rather poor.
Amylogram_2Amylogram: value 318 AU indicate great amylolitic activity resulting in to sticky bread.

Wheat gluten (miàn jīn, 面筋)

In ancient China wheat gluten was used as a meat substitute.

Mainly it is prepared as:

1. yóu miàn jīn (油麵筋), miàn jīn qiú (面筋球) or miàn jīn pao (面筋泡)

2. zhēng miàn jīn (蒸麵筋) or miàn lún (麵輪) and

3. kǎo fū (烤麸)

Fresh and preserved miàn jīn can be used to simulate pork, poultry, beef, or even seafood.

But, there are big difference between cultivars in amount and quality of gluten. Wet gluten readings of our wheat cultivars (bold) in comparison with one well known France cultivar (Renan), and two Austrian wheats (Edison and Ludwig) are presented in table:

* HMW Glu subunit composition for cv. DIVANA: 2*, 7+9, 5+10

Acording to the Chinese grading system for high-gluten flour at least 30% gluten is needed (A. Zhang).

DIVANA in comparison with durum wheat in pasta production

Experimental pasta production performed in the pasta factory “CROATIA” Osijek. Standard methods
(Official Gazette 53/83) were used. Organoleptic evaluation done by 10 evaluators at Osijek University.

Report
by Prof. Dr. Zaneta Ugarcic-Hardi,
Osijek University, Croatia

  • Divana has higher good quality gluten content than durum wheat!
  • Pasta made from Divana was strong and elastic, in general equal to pasta from durum wheat
  • Deficiency: Divana has lower amount of yellow pigment (2.89 mg/kg) and produced pasta was not yellow as pasta produced from durum wheat. (Curcuma as additive recommended)
  • Divana is classified as the good raw material for pasta production.

How to improve grain yield and retain high grain quality

1. By planting a seed mixture:

In dense population and higher N application the excellent quality cv. Divana is prone to lodging and it is not possible to improve rather low grain yield.

By use a seed mixture of cv. Divana (110 cm) and cv. Koleda (90 cm) or Cerera (90 cm) in mercantile grain production this problem could be solved.

Grain yield will be improved, and high grain quality will be retained.

Suggested seed ratio Divana : Koleda is 1:2 or 1:3 but for the best results additional experiments should be performed in specific environment.

In this way obtained yield could be even higher than that of cv. Koleda, and grain quality could be similar to that of cv. Divana. The Role of Wheat Cultivars Blend on Grain Yield and Backing Quality

2. By adopting a SCI (System of Crop Intensification):

Additional boosting of yields is possible if sufficient organic matter can be provided to the soil – little or no inorganic fertilizer is required and there is little if any need for agrochemicals in crop protection against pests and diseases. Requirements for seed, as well as for irrigation water are reduced.

Agriculture in the 21st century must be practiced differently from the previous century; land and water resources are becoming relatively scarcer.
