Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	NOTE 2. Business We are a specialty ingredient company focused on the development, production, and marketing of products derived from traditional and ancient small grains. We create and produce products utilizing proprietary processes to deliver improved nutrition, ease of use, and extended shelf-life, while addressing consumer demand for all natural, non-GMO and organic products. Notably, we convert raw rice bran into stabilized rice bran (SRB), and high value-added derivative products including: RiBalance, a rice bran nutritional package derived from SRB; RiSolubles, a nutritious, carbohydrate and lipid rich fraction of RiBalance; RiFiber, a fiber rich insoluble derivative of RiBalance and ProRyza, a rice bran protein-based product. SRB is an additive used in human and animal foods. SRB has certain attractions compared to additives based on the by-products of other agricultural commodities, such as corn, soybeans, wheat, and yeast. Our SRB and SRB derivatives are healthy, natural, hypoallergenic, gluten free, and non-genetically modified ingredients used in a variety of applications. We produce SRB from four locations: two facilities located within supplier-owned rice mills in California; and two company-owned facility in the Louisiana and Arkansas delta region.

Minimum lease payments include the fixed lease components of the lease and any variable rate payments that depend on an index, initially measured using the index at the lease commencement date. Lease terms may In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease. When we cannot readily determine the discount rate implicit in a lease, we utilize our incremental borrowing rate, the rate of interest that we would incur to borrow, on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. To estimate the incremental borrowing rate, we reference a market yield curve consistent with our assessment of our credit quality. We recognize operating lease expense related to the minimum lease payments on a straight-line basis over the lease term. For finance leases, we recognize amortization expense related to the minimum lease payments on a straight-line basis over the lease term while interest expense is recognized using the effective interest method. Expense related to variable lease payments that do not Revenue Recognition We measure revenue as the amount of consideration we expect to receive in exchange for fulfilling product orders. Incidental items that are immaterial in the context of the contract are recognized as expense. Our contracts do not may We capitalize the incremental costs of obtaining a revenue contract and amortized those costs on a straight-line basis over the expected customer relationship period if we expect to recover those costs. As a practical expedient, we expense costs to obtain a contract as incurred if the amortization period would have been a year or less. Typically, costs to incur revenue contracts are not Selling, General and Administrative Expenses Share-Based Compensation no We have outstanding common stock options as of December 31, 2022 2021. not 2020. We recognize forfeitures of employee and director awards as they occur. In the event an employee or director terminates service prior to the vesting of an award, we reverse the entire amount of previously recognized compensation expense related to the award. Share-based compensation for awards to nonemployees is calculated as of the grant date, taking into consideration the probability of satisfaction of performance conditions, in a manner consistent with awards to employees. The expense associated with share-based awards for service is recognized over the term of service. In the event services are terminated early or we require no Income Taxes We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered or settled. We recognized deferred tax assets for deductible temporary differences and operating loss and tax credit carryforwards. When necessary, we establish a valuation allowance to reduce that deferred tax asset if it is more likely than not not may may may may no We recognize interest and penalties related to uncertain tax positions, if any, in selling, general and administrative expenses.

Lessee, Leases [Policy Text Block]	Leases We recognize right-of-use assets and lease liabilities based on the present value of the future minimum lease payments over the lease term, beginning at the commencement date, for leases exceeding a year. Minimum lease payments include the fixed lease components of the lease and any variable rate payments that depend on an index, initially measured using the index at the lease commencement date. Lease terms may In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease. When we cannot readily determine the discount rate implicit in a lease, we utilize our incremental borrowing rate, the rate of interest that we would incur to borrow, on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. To estimate the incremental borrowing rate, we reference a market yield curve consistent with our assessment of our credit quality. We recognize operating lease expense related to the minimum lease payments on a straight-line basis over the lease term. For finance leases, we recognize amortization expense related to the minimum lease payments on a straight-line basis over the lease term while interest expense is recognized using the effective interest method. Expense related to variable lease payments that do not

Share-based compensation for awards to nonemployees is calculated as of the grant date, taking into consideration the probability of satisfaction of performance conditions, in a manner consistent with awards to employees. The expense associated with share-based awards for service is recognized over the term of service. In the event services are terminated early or we require no
