Description

  The present invention relates to a sweet potato vinegar beverage containing vinegar obtained from sweet potato as a raw material and a method for producing the same, and more specifically, a unique flavor such as potato odor and earthy odor derived from sweet potato, a sour taste peculiar to vinegar, and an irritating odor The present invention relates to a sweet vinegar beverage having a good taste and excellent palatability, and a method for producing the same.

  Traditionally, vinegar has been used as a vinegar for flavoring and storage of foods and drinks, but in recent years, as the appetite promoting effect, sterilization and bacteriostatic effect, etc. become clear, the use as vinegar only In addition, vinegar itself has been actively consumed and ingested, and attempts have been made to develop foods and drinks containing vinegar suitable for this.

  However, in general, vinegar has a strong acidity and pungent odor, so if you drink it as it is, it may be difficult to drink and may cause excessive irritation to the stomach. There is a demand for ease of drinking, that is, excellent palatability while mitigating odor. Therefore, conventionally, means for imparting sweetness by mixing vinegar with drinking water and diluting, or further adding an appropriate sugar, etc. are used as usual methods. The present situation is that the irritating odor is not completely eliminated, and an excellent taste is not obtained.

  In view of this point, it is clear that the present inventors can expect various effects such as improvement of arteriosclerosis and improvement of lifestyle-related diseases such as heart disease, diabetes, and hypertension, among other vinegars in recent years. Developed a beverage using black vinegar, which is attracting attention for its use, and in this beverage, by blending a predetermined amount of sucralose, which is a high-intensity sweetener, it suppresses sourness and irritating odors and is excellent Have found that a beverage having a good flavor can be obtained. (Patent Document 1)

  On the other hand, vinegar is well known to be obtained by saccharification, alcoholic fermentation, and acetic acid fermentation using starch raw materials and saccharide raw materials as starting materials. Generally, grains and fruits are used as starting raw materials. It has been. In recent years, other than these, moss and the like are also used as raw materials, and various vinegars that take advantage of the characteristics of the raw materials are also attracting attention.

  In particular, among vinegars obtained from moss, vinegar obtained from colored sweet potatoes such as Ayamurasaki contains abundant pigments such as anthocyanins, so it has a distinctive color and has a vivid appearance. At the same time, various physiological effects of this anthocyanin are expected, and this has attracted attention.

  However, vinegar obtained from sweet potato as a raw material has a peculiar flavor compared to general vinegar, specifically, potato odor and earthy odor. It was difficult to use. In addition, the present inventors tried to improve the flavor of sweet vinegar-derived vinegar using sucralose, the effect of which has been clarified, but were unable to obtain a sufficient effect.

JP 2002-335924 A

  Therefore, the object of the present invention is not only masking the acidity and pungent odor derived from acetic acid, but also the sweet vinegar beverage having good taste and excellent taste without potato odor and earthy odor peculiar to sweet potato vinegar and its production It is to provide a method.

  As a result of intensive studies to solve the above problems, the present inventors have solved this problem by mixing vinegar, honey, and high-intensity sweetener obtained from sweet potato as a raw material at a certain ratio. The present invention was completed by finding that a sweet vinegar beverage can be obtained.

  That is, this invention provides the sweet vinegar drink characterized by containing the vinegar obtained from a sweet potato as a raw material, honey, and a high sweetness degree sweetener.

  Moreover, this invention provides the manufacturing method of the sweet potato vinegar drink characterized by mix | blending honey and a high sweetness degree sweetener with the drink containing the vinegar obtained from a sweet potato as a raw material.

  The sweet potato vinegar drink obtained by the production method of the present invention is not only masked by acetic acid-derived acidity and pungent odor, but also has a good taste and excellent palatability without the potato odor and earthy odor peculiar to sweet potato vinegar. Is.

  As the sweet potato that is the raw material of the vinegar used in the present invention, colored sweet candy such as Ayamurasaki, Yamakawa purple, Tanegashima purple, Jay Red, Benihayato, Sunny red, among others, anthocyanins that can be expected to have various physiological effects, among others Colored sweet potato rich in the active ingredients is more preferable. Specific examples include purple sweet potatoes such as Ayamurasaki, Yamakawa purple, Tanegashima purple.

  The vinegar used in the present invention can be obtained by a general method for producing vinegar using sweet potato as a raw material. That is, the vinegar used in the present invention is obtained by saccharifying sweet potato with koji and / or enzyme, adding yeast and subjecting it to alcohol fermentation to obtain an alcohol fermentation liquid (hereinafter referred to as “moromi”), and the resulting moromi or moromi It can be obtained by adding a fermentation broth (seed vinegar) containing acetic acid bacteria to the alcohol purified from, and subjecting it to acetic acid fermentation. The vinegar thus obtained can be used as it is in the present invention, but may be filtered and sterilized as necessary. Moreover, you may steam, grind | pulverize, and squeeze as needed before saccharification. These saccharification / alcohol fermentation / acetic acid fermentation processes can also be carried out continuously in the same container by a stationary fermentation method or the like.

  Here, the saccharification reaction may be performed under conventional conditions. For example, the reaction may be performed at 55 ° C. to 60 ° C. for 8 hours to 24 hours. The reaction conditions for alcohol fermentation may be, for example, 15 to 30 ° C. and 3 to 15 days. Acetic acid fermentation may be performed, for example, at 25 ° C. to 35 ° C. for 48 hours to 120 hours after adding a fermentation liquid (seed vinegar) containing acetic acid bacteria. Examples of acetic acid bacteria include Acetobacter aceti and Acetobacter pasteurianus.

  According to the findings of the present inventors, in the method for producing vinegar using sweet potato as a raw material, a sufficient amount of alcohol can be obtained even by alcohol fermentation compared to vinegar using a general grain or fruit as a starting material. There is a problem that acetic acid fermentation tends to be difficult to proceed although the cause cannot be obtained. Therefore, in the method for producing vinegar used in the present invention, it is preferable to add alcohol to the mash obtained by alcohol fermentation, or to add a fermentation aid during acetic acid fermentation. Among these, it is more preferable to add a fermentation aid during acetic acid fermentation because brewed vinegar with good flavor can be efficiently obtained without losing the material feeling of the raw material without adding alcohol separately. In the vinegar production method, a method in which no alcohol is added is more preferable.

  Here, the fermentation aid may be anything that promotes fermentation from alcohol to acetic acid, and examples thereof include yeast extract, ammonium salt, potassium salt, and magnesium salt. Examples of the ammonium salt include ammonium chloride, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, and ammonium sulfate. Examples of the potassium salt include potassium chloride, tripotassium phosphate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate and the like. Examples of the magnesium salt include magnesium chloride and magnesium sulfate. These may be used alone, but may be used in combination of two or more. From the viewpoint of having an excellent fermentation promoting effect, yeast extract, ammonium dihydrogen phosphate, potassium dihydrogen phosphate and magnesium sulfate Is more preferably used as a fermentation aid. Each mass ratio is 5 to 50 ammonium dihydrogen phosphate, 0.5 to 5 potassium dihydrogen phosphate, and 0.2 to 2 magnesium sulfate when the yeast extract content ratio is 1 from the viewpoint of good fermentation promotion efficiency. Preferably there is.

  The amount of fermentation aid added is preferably verified experimentally because the preferred range varies depending on the raw material of the brewing vinegar, but there is no adverse effect on the flavor and quality of the brewing vinegar due to the fermentation aid, and it is sufficient From the viewpoint that a sufficient amount of acetic acid can be produced, it is preferably added so as to be in the range of about 0.005 to 0.23 w / v%, preferably 0.01 to 0.10 w / v% in the fermentation broth containing alcohol.
