Provided are Saccharomyces cerevisiae SPC-SNU 70-1 (KCTC 12776BP) which is novel natural Korean lactic acid bacteria isolated from traditional Korean nuruk, and Lactobacillus brevis SPC-SNU 70-2 (KCTC 12777BP), Lactobacillus curvatus SPC-SNU 70-3 (KCTC 12778BP) and Lactobacillus sanfranciscensis SPC-SNU 70-4 (KCTC 12779BP) which are novel natural Korean yeasts isolated from traditional Korean nuruk.

[Problem] To produce a frozen bread dough improver that has an effect of improving rising of frozen bread dough, is highly safe, and tasteless, using a method that is low-cost and low in environmental impact. Also, to effectively use yeast cell body residue produced as a byproduct of yeast extract.

[Means for Solving the Problem] Yeast cell body residue remaining after extracting useful extract from yeast is suspended in water and heated, after which the suspension is subjected to centrifugal separation and a supernatant is obtained. This fraction contains, per solid content, at least 45 wt % RNA, at least 5 wt % dietary fiber, and at least 10 wt % protein, and mannan content in the dietary fiber is at least 60 wt %. This can be used to improve rising of frozen bread dough.

A proofed frozen dough includes a dough mixture of flour, water, and optionally additives; gas bubbles dispersed throughout the dough matrix; a spent yeast component; and a preserved yeast component. According to some aspects, the preserved yeast component includes encapsulated yeast, fat-coated yeast, non-hydrated active dry yeast, non-hydrated instant yeast, non-hydrated semi-dry yeast, non-hydrated frozen yeast, or a combination thereof. A frozen dough product can be prepared by mixing dough ingredients to produce a dough composition, where the dough ingredients include water, flour, a first yeast, and a second yeast; proofing the dough, where during proofing the first yeast is spent and the second yeast is preserved; and freezing the dough after proofing.

The subject invention provides compositions and methods for enhancing the quality of bread and other baked goods. By baking the bread or other baked goods with a yeast-based biopreservative composition, the subject invention provides methods for enhancing the taste, texture and shelf-life of these food products. In certain embodiments, the yeast-based preservative composition comprises Wickerhamomyces anomalus and/or a microbial growth by-product. The composition can be used in place of or in addition to traditional baker's yeast.

Provided is functional well-being pizza dough and a pizza prepared by using the same, which is digestible and increases savor and flavor by containing a great deal of fiber. The functional well-being pizza dough manufactured using dough mixed of 2,750 to 2,800 parts by weight of wheat flour, 1,300 to 1,400 parts by weight of water, 110 to 120 parts by weight of refined sugar, 70 to 80 parts by weight of soybean oil, 80 to 90 parts by weight of grain-nut mixture, 50 to 60 parts by weight of refined salt, 20 to 30 parts by weight of whey powder, 8 to 12 parts by weight of bread improver, 4 to 6 parts by weight of sourdough, 4 to 6 parts by weight of yeast, 2 to 4 parts by weight of chlorella powder, and 1 to 4 parts by weight of green tea powder.

The invention relates, in certain aspects, to a novel baking process that allows for the production of a gluten-free laminated baked good. In certain embodiments, the baked good of the invention has a look similar or indistinguishable from that of a conventional gluten-based baked good. In other embodiments, the baked good of the invention has a taste similar or indistinguishable from that of a conventional gluten-based baked good. In yet other embodiments, the baked good of the invention has a texture similar or indistinguishable from that of a conventional gluten-based baked good.

Pizza dough for later use, which can be stored at refrigeration temperature for up to 100 days with artisanal quality, comprising in percentage by weight of the finished product: flour (50-65), water (20-35), fats (0-8), salt (0.7-2), sugar (0-2), deactivated yeast (0.05-0.15), fermented flour (0.1-2), vinegar (0.1-2), baking powders (0.5-2), gums (0.1-3).

The present disclosure discloses a microwave processing method for food made of flour and rice fermented with sourdough and belongs to the technical field of food processing. It comprises: adding a sourdough to the raw material to prepare a steamed cake batter; fermenting the batter under the dielectric constant of 20.sup.˜34, the loss factor of 6.3.sup.˜9.0, the moisture content of 45.sup.˜55% and the water activity of 0.920.sup.˜0.980; and using microwave heating to obtain the microwave-steamed cake. Due to the regulating effect of the sourdough fermentation on the dielectric properties of the food material, it solves the problems of hard core, textual firmness and toughness, dryness and weak flavor caused by fast and uneven microwave heating without adding food additives; meanwhile, the sourdough fermentation process is optimized and the DY and additive amount of the sourdough are controlled to obtain the microwave-steamed cake with larger specific volume, lower hardness, more fine and uniform pores and better taste.

The present disclosure discloses a brown rice and oat bread with low glycemic index and a preparation method thereof, which belongs to the technical field of grain processing. The brown rice and oat bread provided by the present disclosure includes the following ingredients: brown rice flour, gluten powder, oat flour, butter, sodium caseinate, salt, yeast, improver, and water. According to the present disclosure, the sodium caseinate is used to help form a dough and improve the flavor of the bread, and the brown rice and oat bread with low glycemic index is obtained with the brown rice bread recipe and special baking process, which is close to wheat bread in terms of specific volume, taste and tissue structure.
