Problems solved by technology

The red koji fermented rice contains active Aspergillus and yeast. Even in a refrigerated state, relatively weak fermentation will produce a small amount of carbon dioxide. If there is an opening on the package, the fermented glutinous rice is easily exposed to external invasion. If it is completely sealed, it will make the packaging flat and cause rupture. Therefore, none of the food packaging or bags in the prior art can meet the packaging requirements of this innovative product. Therefore, it is necessary to design a " "breathable packaging", which can effectively prevent the invasion of external bacteria, and can smoothly discharge carbon dioxide, and can reliably maintain the quality of the red yeast rice wine of the present invention. The selection is very strict, and there is no disclosed relevant sealing material in the prior art that can be used for the packaging of red yeast rice wine

Embodiment Construction

[0017] The technical solution of the present invention will be further specifically described below through specific examples.

[0018] First, the preparation method of the non-sterilized red yeast rice fermented glutinous rice provided by the present invention is carried out according to the following steps:

[0019] (1) Select fresh japonica rice or glutinous rice or a mixture of japonica rice and glutinous rice as raw materials, and use Rhizopus wine medicine accounting for 0.2-0.8% by weight of raw materials as a saccharification starter, such as 0.2%, 0.3%, 0.4% , 0.6%, 0.8%, etc., use red yeast rice as a supplementary saccharification starter, such as 1%, 3%, 5%, 7%, 8%, 10% and so on; Wash with tap water, and then soak for 22-24 hours, such as 22 hours, 22.5 hours, 23 hours, 23.5 hours, 24 hours, etc. The specific time required is until the raw materials are soaked until they are pinched with fingers and become powdery;

[0020] (2) Rinse the soaked raw materials with ...

Abstract

The invention relates to a novel application of a high polymer material in the field of fermented foods and particularly relates to a novel application of a PTFE (Polytetrafluoroethylene) film to brewing of a sweet red yeast rice wine. The sweet red yeast rice wine is contained in a fixed-shaped open vessel; an opening part of the vessel is sealed by using a sealing element which is at least ventilated at a local part and can isolate microorganisms in the environment; the sealing element is composed of a bonding part bonded with the wall of the vessel and a functional part with ventilation and isolation functions; and the PTFE film is used for processing the functional part of the sealing element. According to the novel application, the PTFE film is used as a packaging film to be applied to the brewing of the sweet red yeast rice wine, so that the guarantee period of the sweet red yeast rice wine can be greatly prolonged and can be up to 8 months to the maximum extent, the PTFE film plays a role in controlling the fermentation speed of the sweet red yeast rice wine, the sweet red yeast rice wine has no flatulence and rancidity phenomena, and the physical and chemical performance indexes of the sweet red yeast rice wine are good.

Description

technical field [0001] The invention relates to a new application of a polymer material in the field of fermented food, in particular to a new application of a PTFE polytetrafluoroethylene film in red yeast rice fermented rice. Background technique [0002] Jiuniang, also known as sweet wine and fermented glutinous rice, is a traditional fermented food of the Chinese nation and a part of the daily diet of Chinese people. Tianjiuniang is well-known both at home and abroad for its unique mellow and delicious taste. From ancient times to the present, the brewing method of Tianjiu Niang is: wash and soak the glutinous rice overnight, twist it into a paste with your fingers, put it in a steamer and steam it, then pour the glutinous rice out of the steamer to cool down to about 32°C, and then put it into a large bowl. Sprinkle glutinous rice 2% liqueur koji on the glutinous rice, turn it over while spreading it evenly, and then form a trumpet-shaped hole in the center of the r...
