The present invention addresses enhancing a taste of common processed food and drink without imparting a foreign taste and without increasing calories or sodium content. In such a case, a substance added to the common processed food and drink is preferably a common foodstuff, and preferably has a high degree of safety. A yeast extract having a peptide content of 5 wt % or more, an RNA content of 5 wt % or more, a free amino acid content of 4 wt % or less, and more preferably having a dietary fiber content of 15 wt % or more is added in an appropriate amount to the common processed food and drink.

Yeast extract having taste-enhancing effect

Low-salt processed foods or drinks frequently taste like something is missing because of the less salty taste thereof. Although salt substitutes and flavoring agents are often used to offer a sense of satisfaction, these additives exhibit only limited effects or cause some troubles of, for example, changing the original flavor of food. Under these circumstances, the present invention addresses the problem of enhancing the salty taste of a low-salt processed food or drink without imparting any undesired taste thereto. To solve the above problem, the present inventors conducted intensive studies and, as a result, found that an effect of comfortably and naturally enhancing salty taste can be achieved by adding a composition, which comprises dietary fibers, in particular, glucan and mannan at a specific ratio, to common processed foods or drinks including low-salt processed foods or drinks.

Salty taste enhancing composition

[Problem] The present invention seeks to provide a composition for plants that is highly safe and that contributes to early harvesting, increasing yield, and increasing added value of crops. Specifically, the present invention provides a yeast extract that, by addition to a foliar surface spray or to soil or water, provides an effect of promoting growth, an effect of root lengthening, an effect of improved taste, and an effect of increased amino acid content of a plant. A substance obtained from yeast that is edible and considered to be safe is preferred as the yeast extract. [Means for Solving the Problem] A yeast extract having a peptide content of 5 wt % or more and an RNA content of 5 wt % or more is sprayed onto or provided as fertilizer to a plant. The yeast extract is preferably derived from, which is edible and considered to be safe.

[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.

[Problem] To make a color of a processed food containing anthocyanin pigment into a vibrant color. In this respect, using a common foodstuff that is cheap and highly safe, without adding a coloring agent, and not imparting an incongruous flavor to the food is preferred. [Means for Solving the Problem] To an anthocyanin pigment or a common processed food containing anthocyanin pigment is added, in an appropriate amount, a yeast extract containing 5 wt % or more of a peptide, 5 wt % or more of RNA, 4 wt % or less of free amino acid, and preferably further containing 15 wt % or more of dietary fiber.

To provide effective use from a yeast extract residue, an excess of which is produced as a byproduct of yeast extract, or reduction in amount of the yeast extract residue. Also to obtain various useful substances. A cell wall lytic enzyme having no protease is allowed to act on a yeast extract residue, after which a heat treatment is performed at 70 to 80&#xb0; C. for 10 to 20 minutes, thereby enabling separation into a fraction of primarily cell walls and a fraction of primarily protein. A yeast protein having a protein content of 60% or more is obtained from the fraction of primarily protein and, by subjecting the yeast protein to enzymatic degradation, a seasoning having a high amount of total nitrogen is obtained.
