چکیده
Abstract A pilot plant scale of SFE (steam flash explosion) chamber has been developed in order to process raw grobogan soybean. The objectives this research were study the physicochemical changes soybean term reaction kinetics approach and determine optimal variables produce high quality We used 2.5 kg 5 soybean, representing 75% 50%, respectively, headspace volume chamber. After soaking water, these soybeans then treated using operated at temperature 115 °C (P=1 bar), 125 (P=2 135 (P=3 bar) time interval 0, 5, 10, 15, 20, 25 minutes, after which steam was suddenly released from provide explosion effect. samples analyzed for hardness, color characteristics, urease index (UI), protein dispersibility (PDI), solubility (PSI). result showed that decrease hardness b-value (yellowness) during processing can be explained by 1 st kinetic model. As gave k T=115°C =0.0344 minutes -1 , T=125°C =0.0495 T=135°C =0.0864 E a =60.350 Kj.mol (for capacity); =0.0314 =0.0442 =0.0858 =66.009 capacity). b-value, =0.0225 =0.0378 =0.0558 =59.873 =0.0258 =0.0393 =0.0553 =64.544 capacity is higher than capacity. This found no appropriate model index, PSI, dan PDI. Soybean under (1 within both capacities satisfy processed requiement.

In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...
متن کاملChanges in RNA Splicing in Developing Soybean (Glycine max) Embryos
Developing soybean seeds accumulate oils, proteins, and carbohydrates that are used as oxidizable substrates providing metabolic precursors and energy during seed germination. The accumulation of these storage compounds in developing seeds is highly regulated at multiple levels, including at transcriptional and post-transcriptional regulation. RNA sequencing was used to provide comprehensive in...

Pigmented Soybean (Glycine max) Seed Coats Accumulate Proanthocyanidins during Development.
The dominant I gene inhibits accumulation of anthocyanin pigments in the epidermal layer of soybean (Glycine max) seed coats. Seed-coat color is also influenced by the R locus and by the pubescence color alleles (T, tawny; t, gray). Protein and RNA from cultivars with black (i,R,T) and brown (i,r,T) seed coats are difficult to extract. To determine the nature of the interfering plant products, ...
